Land Rover Defender L663 - Low Battery Warning ! - Static Power Drain Investigated ...
Вставка
- Опубліковано 30 вер 2024
- In this video we look at what the current draw is on the battery when you unlock and open the door on the Land Rover Defender L663. We look at which circuits are consuming the power and how much. Maybe Land Rover could devise a "camping mode" to stop some of these circuits powering up when you are camping.
Here is the link to our Defender FUSEBOX spreadsheet

This is what I like about this channel. Acknowledge the problem. Identify the cause. Propose a solution. Three simple steps and if anyone dares to make silly accusations of you bad-mouthing Land Rover, I will personally be very annoyed. If anything, I think Land Rover will welcome this kind of feedback. Excellent video and your proposed solution is brilliant.
Thanks Andrew - I love my Defender as you know but as an engineer I need to understand why I am getting warning messages ! I am sure Land Rover are working on improvements to this issue.
very good video indeed. I am not sure if latest defenders has the same problem or its fixed. any idea?
Simon, I'm a member of the JLR Advisory Board, this is a superb video on an issue which plagues all JLR owners, be it EV or Normal powertrains, I'm posting a link to your video for other JLR members in the hope it gets passed up the chain.
Hi - I too hope this get some attention. I love my Defender and I love camping with it - Land Rover even sell roof tents for the Defender so its important that the car can deliver on the lifestyle offered. I may investigate further as it seems there is a signal that comes from the BCM to wake up the infotainment relay on the rear circuit board.. I will data log this and see how it behaves.
Did anything come of it? I've just come back from camping and had exactly this problem.
just for documentation purposes in case anyone stumbles upon this comment
simon did a video showcasing the "unlock tailgate" feature, which circumvents the infotainment startup, potentially saving those mentioned 3 amps over the duration of the camping session
As an overlander, that is an excellent video. When you have a second battery system with a fridge and a couple of other items drawing power, you really do want to conserve as much energy as possible. I think LR would destroy the market if they included a camping option under the off-road options. Select it when you park and it stays on until you select any other drive mode.
I do hope Land Rover listen to this idea - it would really help those of us that like going away in our cars.
@@L663 I think they could add it as a menu option in Pivi, and also allow you to configure which lights come on, or default them to manual for example. Where I think they'll struggle is adding it to the Remote app as that would require a 4G signal to work. If you tried to use 'local' bluetooth you'd need Pivi to be running again. I wonder how much the built in modem and associated electronics for that use? Or whether they only function if Pivi is on, likewise SOTA.
I also thought one of the features of Pivi was it's own battery to help with keeping it alive. The media press release is not too specific. I wonder where that is?
Some kind of battery saver mode would be a great idea. Disable the infotainment system put certain LEDs into a low power mode, maybe shorten the delay certain light stay on after you close the door
0.63a for the loadspace light, that I do know. Although that will be halving for a near comparable output soon! :)
Hi Tim - thanks for the data on the extra lamp - the 8W your light takes is useful and much appreciated when camping / cooking etc. Where the other 112W of power is being used is what puzzles me !
Nice to see this come up after our brief chat online the other day.
I’ve just been camping in the Zambezi valley for a week (video coming up soon) and I have now worked out that if you open the rear door the infotainment doesn’t start up. Any of the four driver or passenger doors starts it up, so leave the doors open and if raining or there are bugs flying around you can close the doors without letting them latch/close completely and eventually everything shuts down and stays off.
Not a perfect solution but works.
At the very least I hope Landrover turn off the startup of everything on the passenger doors and leave it on the drivers door. Makes more sense for us who use our vehicles in remote areas.
I also have a dual battery system but this is stand alone with solar power so running the fridge and exterior lighting does not affect the vehicles battery
Great idea enabling a camping mode from the app. My L663 constantly displays low battery - I wondered whether it was because the car is approaching two years old but a car security specialist said that even on a long run the battery does not fully recharge - Not sure if that is true. I might mention to the JLR service team when it goes in for its first service but suspect they will blame the dash cams I had installed, however, I know they switch off when the battery goes below a certain voltage.
My battery was replaced when it was just a few weeks old.
@@L663 That’s interesting to know - Thanks Simon.
The defender has a smart alternator. So it gets to about 95% and shuts off. The battery doesn't fully charge.
Awesome video Simon. I've just had this problem the last couple of weeks camping here in Australia. I've sent an email to my Land Rover dealer with a link to your video (hope you don't mind). Kind of glad it just isn't me. Thank you for the fuse spreadsheet as well.
Yes I hope Land Rover will listen to us - 10 Amps is a lot of power draw.
@@L663 which leads me to another question. How long do I run the car, before it's okay again?
Hi Simon, great video and I experienced the same issue the first time I took the car out for camping last year. I have a Defender MY2022 for our first overlanding trip last year we went through Southern Oregon and Northern Nevada; the morning right after the first night out camping I got the "low battery warning" message. During the whole trip I kept the interior lights off (when it's dark we use headlamps anyway to move around the camp) but also I kept 1 door slightly open all the time until we were done and ready to go to bed, as just one door slightly open disables the screen and the PIVI system, they don't to wake up any time you open the other doors to access your stuff in the car. That was my workaround for the trip and since it worked I keep doing it anytime I go camping. It’s far from ideal so I 100% agree an additional driving mode would be great!
Agreed there is a post on this in our facebook group around a year ago where we also suggest a camping mode, its terrible as is when you're camping usually your car is your base and your in and out of it constantly sometimes for a week or more, battery conservation dual batteries or not is crutial even if you have solar. The mode will also be super helpful when you are working on your car a whole day or over multiple days when you are opening closing the doors constantly and get the dreaded low bat warning. Looking forward to what you and Landrover come up with Simon, great Vid and welcome to your new Cheif Filming Officer too 😉👍🏽
Thanks Ben - Lily is doing a good job with the camera and helping in the workshop !
@@L663 Fantastic, well done Lily! 🙂
That is an interesting discover Simon. I notice that the speed in which the systems shut down (the radio for example) increases as the battery ages so must monitor the voltage very closely. I wish I could listen to a 30 minute radio programme whilst sitting in the car but about 10 minutes is the best I can ever get and that drops rapidly as the battery ages. Years ago I could sit in my Cortina Ghia with my Mum and Dad and listen to a whole afternoon of Sunday music without any battery problems. It must be progress!😳😳😀😀😀Richard
Hi Richard - I think what I am seeing is an unforeseen consequence of what is a clever idea to improve start up times. I think one more iteration of the logic / addition of a camping mode will see this improve - fingers crossed !
Is there anything as simple here as a door switch that could have a second switch added in series to fool the car that the rear door is shut ?
You are doing such a good job!
I experienced the problem myself and would have narrowed down the issue exactly the way you already did. But now I don't have to. Thanks for the fuse plan. I'll be manipulating some fuses with a switch now.
BUT LAND ROVER PLEASE LISTEN WE NEED THIS CAMPING MODE!
I am still trying to work this out - i need to workout the signal wire from the BCM
@@L663 By the way, I noticed the external socket panel on this video. I'm still searching for a way to connect the roof tent and solar panels to the storage inside. Is that panel one of your designs, or where can I get this panel?
Доброго здоров'я привіт з Одеси Україна.
Hope your day is going OK.💛💙💛💙
We’re thinking of you all in the Ukraine 🇺🇦 peace
Should have called it the appollo 13 vid!
I was thinking the same thing! Good thing the Landy engineers weren’t designing the lunar module
The puzzle is finally solved, app camping / battery saver mode would be ideal, in the absence of that some kind of easy switching option would be handy 👍🤓
I think Land Rover could really gain some credit by offering a camping mode / airport mode / holiday mode - battery save option. I guess this is all doable with SOTA ?
@@L663 SOTA yes absolutely, let’s hope LR listen as, in the scheme of things, it doesn’t feel like a complicated one.
Fit an auxiliary battery, like the army land rovers had. Small 12V lithium should be better to fit under some plastic trim.
Brilliant video, get it , brilliant
Perhaps add a solar panel for camping. Roll up ones now available. Bug Out Vehicles UK channel might be a good place to look.
I guess i would just rather my car did not use 120W of power just with the door open - but i will take a look at the solar options.
My L322 does that all the time too. Low battery warning. I should see what’s going on… I just thought it was another Land Rover quirk.
Unfortunately this is a challenge I’ve experienced on every overlanding trip I’ve done with my 2020 Defender. We also have a D5 and had similar issues that left us with a dead battery.
Thank you for confirming what I suspected after my first big camp with the 110 and low battery warnings. I have been hoping Land Rover would engage a “camping mode” - other cars have it, and I think it could be a software fix. Beyond all that, the best solution I have found for camping is: key in a faraday box. Holding and getting a flashing light on the overhead lights, so they don’t turn on when you open the door (its in the iGuide). And now possibly pulling the pivi pro fuse (thank you!) The other wise/practical solution is to have a portable battery jumper (mine is a noco and its brilliant if you truly find yourself with a dead battery in the middle of nowhere). Thanks as always for such a good post! (And I’d buy a remote fuse disabler in a second if such a thing existed for the 110)
Hi Steven - my key is not keyless entry so the faraday cage thing is not a factor for me - but i can see this would be a problem for you as your key would be in close proximity of the car - so "camping mode" would need to disable keyless entry ! I am not sure if a fuse disabler is available or if we will need to design this into a loom onto the pivi pro unit ( under the passenger seat )
@@L663 I actually am not convinced 'camping mode' would need to disable the keyless entry. I think even with pivipro simply disengaged it would be a significant help with battery drain. As for the key, a faraday box/bag is an easy work around too (and smart just to have with sneaky car thieves)! My biggest issue while camping in the back, was trying to be sly and not disrupt folks... and if I crawled out the back by opening a door, the pivipro screen would light up for 10 minutes... basically alerting everyone in neighboring camps that yes, I had too many pints and had to use the loo. Not cool. :-)
Question: Does the Activity Watch also draw on the battery, the way the keyless entry does?
@@stevenburnsvideo My concern with the keyless entry was not to do with power consumption - it was to do with theft - if I had keyless entry and was in the roof tent then the key would surely be close enough to allow the doors to be opened ?
I have the looms for the rear door release just come in so look at for this !
@@simonjefferson Exactly. Everyone with keyless entry should probably use a faraday pouch/box - it's just too easy to swipe RFID info.
Late to the party! 🥳 Our Brutus is left unlocked and never get this, although when it was in the main dealers they did mention that the battery was low!
Parasitic Drain - agree 10 amps is a lot. I had a 2006 Fiesta that used to flatten the battery if left for 2 days - turned out to be a faulty central locking module.
Simon, is it possible to interrogate the system to see where the threshold for the alarm is? Ours started doing this at the weekend, I've done a few hundred miles and it alarmed again today. I've just put the battery on charge with a workshop charger and it's telling me the battery is fine, fully charged within minutes. Is it possible some recent update has "shifted" the point at which the alert appears?
We have decoded the CANbus and found the voltage signal and we can also see the low battery warning on the CANbus - I will take a look some more and see if we can get the exact value of voltage ( I am pretty sure it will just be a voltage ) that triggers the warning
Also had this issue camping in Australia, thanks for doing the hard detective work
No worries
I am currently touring Europe and had this issue. I tie a sock around the door latches whilst I’m near the car to stop them closing, turn off interior lights, carry a nocco and I also carry ctek charger and occasionally pull up at an electric pitch to charge the car over night. This has been doing okay so far but it is a pain. Bare in mind I have a solar panel and jackery for all my personal needs. It’s solely the car draining it’s own battery.
It seems that there are quite a few people being inconvenienced with the power drain issue. I will continue my investigations. I will look at the wiring diagram and see if i can find if there is a relay controlling these things that we can intercept the signal too and create a hardware "camping mode".
A quick way to know if your battery is low and in poor nick is if you car stops cutting out when idle.
I believe when the engine is below 60% charged it will not cut the engine when stationary.
Yeah had that on my Freelander 2. 7 Year old battery meant that eco mode never worked.
Yes the stop start does indeed stop working - but my battery was fine and fully charged on Sat morning - but low by Sunday afternoon !
@@L663 does the defender not have a second battery for stop start like the discovery 4
@@markrigby9588 It looks like this was only fitted to cars with PHEV
@@markrigby9588 two batteries is sensible when you consider the gear inside the car.
Land Rover doesn’t consider that this kind of thing will simply push people to get a Grenadier.
Recall ref n846 just issued by Land Rover take a look on urgent basis to do with hybrid system
Maybe LR should have an option called "camping mode" where the current draw is down to a minimum. Or maybe even a configurable option in the infotainment-system, where you can do your own setup? Ideal for those people venturing far outside Chelsea :p
Just got my landy and will take a solar panel charger with me when i go and connect it to the terminals under the bonnet..i dont want to be stranded up in the Yorkshire dales.
Wait, so if there is an issue you dont just throw your hands up and say the only solution is a Land Cruiser? Weird.
Purely by experimental method, I found out that if one of the four doors (not the trunk) remains ajar, and the Defender falls asleep with this door ajar, then in the future the opening and closing of other doors will not wake up the car!
This will already save us a lot of energy, however, the car’s reaction to the key still remains. According to the dealer, every time the Defender detects a key near the vehicle, it initializes the basic systems to then speed up starting, and also turns on the fuel pump. If the car is not started, the systems turn off, but every time the car detects the key, it starts the systems again - and all this wastes battery power.
With the new gen of EVs power consumption should be a factor, a basic EV with no frills would have a massive range potential..
Some very good ideas Simon. There is transportation mode, that kills most things. Maybe good if you are camping for a week
I need to look at the transport mode and see how to activate that.
@@L663 it’s in the Landrover remote app vehicle settings , there’s service mode and transportation mode
@@Bikeaddict4235 The service mode was removed from the latest app - not sure of the transport mode has also been removed - which app are you looking at ? the white or black background one ?
HI Simon , I didnt realise there was another app,mine in remote mode the background is white, home screen is top half black and bottom white , both Smode and T mode still there on mine @@L663
Version 2.10
Hi Simon, after our chat at Gaydon on Sunday about this I've been meaning to do a test on my Discovery Sport. Did you test what the power draw difference is between closing the doors and leaving things to rest, single locking & double locking. I've heard things before about dealers blaming flat battery issues on customers not double but only single locking their cars when parked int he garage. Keep up the research!
Yes a switch that interrupts the circuit you can use when camping sounds like a good idea.
Looking at the wiring diagram there is a signal from the BCM that drives a relay in the rear fusebox... intercepting that signal may be the method we need
Simon. Like Sandy Munro, but better.
Sandy Munro is my idol !
Amazing and helpful information each and every time. So useful no matter which side of the pond you're on. Thanks so much for all your excellent work for us Defender owners!
Thanks - yes most of my findings should apply even to those with the steering wheel on the wrong side !
Another informative video Simon. Thank you.
I was thinking, if you close and lock the car after opening it to retrieve something then does the 120w draw drop to the normal, dormant level?
I don't know if it does, does anyone know?
We can look at this - a good point
Hi Simon, when I go camping with my 110, I now place a small carabiner in the rear barn door locking mechanism and double lock the vehicle. The car powers down and this way I can keep the barn door open and avoid packing away cooking/wash up paraphernalia that hangs off my fold down table. If you leave the passenger door ajar or the vehicle unlocked, the key proximity sensors keep communicating with the key (or activity watch) and occasionally the recirculation fan and/or the pivi pro will fire up, I have no idea why but have experienced this many times now. Before the carabiner trick, my headlights also used to turn on when someone opened a door, at least until I switched this off in the settings. I installed a 100Ah aux lithium battery through a dc/dc charger for the fridge and accessories and wired 3D Tim's overhead loadspace light through a three position switch so that it can run either off the aux, off the ignition or be powered off altogether. One thing to note, if you keep ignoring the low battery warning on the dash, you will eventually need a jump start and this will require a device that can provide >650 CCA (most lithium jump starters are 400 or less) or you'll need to recharge the main AGM from a running donor vehicle for a long time before it will crank over. I learnt this the hard way.
Hi Darren - thanks for the tip on the rear door but this is not really a full solution if you want to lock your car etc. My car does not have keyless entry so i am more fortunate in that it does not trigger from the key. I hope Land Rover will look into this issue !
@@L663 I'll keep my fingers crossed for a camping mode solution in a future software update 😴...however the battery drain issue is not new and unique to the new defender. I hope you can get this issue onto their kanban, but until (or even if) such a release is pushed, I'll be applying workarounds and carrying a lithium jump starter for piece of mind, especially if I've been caught winching late in the day.
@@L663 Hi Simon further to my previous comment, I just read the post from Overlanding with Bruce and he is 100% correct that if you open the barn door when the vehicle is locked that it doesn't fire up the pivi pro OS. So one solution is to have everything you need accessible from the loadspace when camping!? The catch to this is that if you don't open a passenger door and then double lock the vehicle, the barn door won't be re-alarmed and can be opened without a key in your pocket. I see positives and negatives to this scenario depending on where you are camping!
I’m convinced the Stop Start function is the big killer. I’ve had Land Rovers for nearly 40 years now of just about every type except Range Rover strangely. As they’ve got newer so the battery lasts less and less. Big difference - early cars - no stop start. My wife’s 5 year old Evoque is now on its 3rd Battery. To be fair she doesn’t do too many long runs and a lot of stop start but after about 18 months the low battery warning is on. Appreciate they have bigger batteries now in theory to compensate but to my mind it makes a mockery of being green with ATP start but having to replace batteries at regular spaces.
Cars with no stop start, use the older style, lead acid battery.
Years ago, your battery would generally last 5 years, or more
( many factors do affect the lifespan of a battery )
Cars have so much more electrical stuff etc nowadays, but, battery size has not increased.
Everything focussed on saving space and weight.
A lead acid battery in a new modern car, generally now won’t last as long as it used to, as modern cars have so much more gadgets in them nowadays.
No stop start means that an average lead acid battery will start the car approx 750 times per year.
( depends how often u drive your car, and how many times u start it up every day )
A car with stop start uses a different type of battery
AGM battery
On a normal drive, the AGM battery will restart the car many times..
Over 17,000 restarts over an average year !!
Stop start battery works very hard, and thus they generally are unlikely to last beyond 3 years.
AGM battery needing replacement after 2 years is not uncommon.
AGM battery very expensive compared to a lead acid battery
But
Manufacturers chasing lower fuel economy and emissions.
Environmental benefits
But
More expensive for the consumer who is replacing the (expensive) AGM battery every 2 to 3 years !!
In my 2017 Disco Sport, I always turn off stop start.
Still on the original AGM battery after 5 years and
90,000 kms
AGM battery is very strong, and will last a long time, IF it’s only being required to start the car 750 times per year, instead of 17,000 times.
Cheers. 👍
Refer my other comment
Your battery experience with your wife’s Evoque, is very common, and backs up what I said
This matter is NOT just a JLR thing
Same with every car nowadays. 👍
I will keep my FJ cruiser.
Dash Cam? We had an EGR Valve issue in France some years ago in our FL2. It went in an excellent garage (Maurienne Auto Diffusion!). They did, however, leave the dash-cam running the entire time they were working on the car. We got the car back to our camp site, ready to go home the following morning and woke up to a dead battery. Nice people on site helped jump start the car. I've kept a Lithium jump starter in our cars ever since. And a charger in the caravan!)
I have the defender 2021 it is not the explorer model . and I am giving up the car because a Battery problem that is occurring the last 3 month , the battery has been changed two times and the problem still there .
What about looking into replacing the stock battery with a deep cycle battery? For example a battery for upgraded car audio systems. How much space is there to place in a larger battery?
Think of installing a switch to force all the Defender's power on and off, just like you did with a trunk interior open switch. Korean custom companies develop this and install a slim mode switch on the Defender to customers. Whenever the door and trunk are opened, the interior light and audio light system are turned on and activated, consuming electricity and displaying a low voltage warning light. The sleep mode module is a device that prevents the vehicle from recognizing even if a door or trunk is opened.

Hi Simon, Thanks for your great videos and products. ( I have purchased your front grill improvement and it looks great!) I have a 2013 Freelander2, SD4 HSE. Is there any chance you could produce a similar schematic chart of what each fuse does for the Freelander. I appreciate it would take up your time but would prove extremely helpful to "Luddites" like me who have great difficulties with the mysteries of "electrics".
In a similar vein - I now carry a portable radio in the car so that I can listen for more than 10 minutes before shutdown.........which is a bit of a basic remedy for something so fundamental to the use of a car. Perhaps Simon could have a quiet word in someone's ear about a fix for this too? Running the engine just to listen to the news is a bit extravagant in every way methinks.
Hi Simon
I have a 230v 180w three pin plug in the boot can you tell me which fuse that is please.
Si
Just charge the auxiliary battery with the trickle charger ,from my perspective the Land Rover is not aware of this and it is not even mentioned in owner's manual handbook how to charge them...
When you park up for say a week or two at the airport how do you make sure you will have enough battery to start engine is there any tricks
Cheers Garry

I had the low battery issue after about a year I had my Defender P400, needed to call Land Rover Roadside Assistance three times to get a boost. Had the battery swapped out and still had some parasitic draw on the battery. The dealer took the car for over a week updated all the software in the entire vehicle and fortunately had some early software updates like wireless CarPlay, ever since then never had the issue with the battery. I purchased a Noco battery booster and fortunately never had to use it yet. I think with the bigger batteries in the Defender the alternator may be too small because larger AGM batteries take longer to charge and require more amps. I always suspected it was the infotainment system that was drawing the power because right before the battery issues started there were some new music apps that were added Spotify, TuneIn etc to Pivipro and there could of been a bug in the Spotify app that was still playing and connected to the internet and drawing power after you shutdown the car and locked it. I don’t think the dealer or Land Rover ever found the actual problem and just updated all the software and firmware to be safe.
I was once told that a D4 draws power for nearly 45mins after turning off, while it shuts various systems down. I learnt from one of your videos, that holding the button for a few seconds turns the interior lights off, now I leave them off permanently.
Really interesting and thank you for publishing this. I have to say I’ve been extremely happy so far with my D250 and compared to my previous XC90 D5 my defender is a dream. I had so many problems with my XC90 which was forever giving me low battery warnings and was replaced once by Volvo. The stop start rarely worked because the battery was never charged enough 🤯 In comparison my D250 has not once, in 10 months, shown a low battery and the stop start always works. I’ve taken note not to leave doors open! Thank you 🙏
Glad to hear you Defender is doing well - and to be fair in "normal use" mine does not give a low battery warning but i do like to go camping with the Defender and I just worry i will go to start the car at a campsite one day and i will be guy with flash new Defender who needs to call out the AA !
@@L663 You could keep one of those small lithium battery jump starters in the glovebox.
@@L663 if anyone can come up with a solution you can 😃👍👍
if i use the fbh on my d4 every day and night by the end of the week i get that battery low message and i travel 60 miles a day,but if i only use fbh in the morning its fine,i even installed a new battery and its the same,got the alternator checked and its all ok,im thinking of installing another battery in the boot
Camping mode would be a great idea (bit late for my ol' D4!). Thought about fitting an AUX/dual battery?
Great video Simon. Who would have thought the pivi was the culprit? Dome lighting always used to be the cause hence the stealth / hunting mode dome light sequence. I wish not only they have camping mode, but automatic car wash mode to disable all of the collision avoidance and hold in neutral while using a car wash.
Wouldn't a sensible compromise be to only trigger the infotainment system to boot when the drivers door opens or even only when it senses someone in the drivers seat?
This is such a great idea! Somebody get this idea to the Land Rover folks.
My suffix A Range Rover has only three fuses!!!! And I very much enjoy camping without any power outages!!!!
Old school maybe a lot more practical!!!
Regards Ian 👨🎤😂⚠️😇🤔👍😎✊🇺🇦✊🇳🇿
I have just purchased a late 3 door Range Rover classic - video coming tonight
Can we fit the touch duo steeringwheel of Range Rover evoque on range rover 2012
Perhaps Land Rover didn't intent it for camping?
2022 P400 with the battery issue here as well, but I don’t go camping. Happens after many short drives. I’ve had to use a noco trickle charger a few times, issue returns after a few days. I make sure to lock vehicle and keep the keys away when not in use.
Hoping for a solution from JLR, hopefully in the form of a software update giving us an option to shut down the pivi pro manually or delay its boot up.
Yes a lot of people are having problems with this issue - I am still looking at options.
Hello, please help me how to save the Google sheet file (Defender FUSEBOX spreadsheet)to my computer for future offline reference.. Thank you
Hi - i just tried to save it as a PDF so i could send to you but it does not work very well - sorry !
One quick question: Where can I get that panel on the rear door with the sockets?
Would be great to connect solar panels or roof tent to.
these rear panels come of easy and they are cheap - you can add parts to these panel really easily

Interesting findings, I literally use mine as a van, I reckon some days I open and closes the back door 20 plus times (and I have the L.E.D light strip from yourselves) sometime the back door is left open for some time whilst unloading, not once have I had a low battery warning in over a year. The Radio shutting off after 10mins of sitting in car is annoying tho.
It may be that the back door is ok - it could be the other doors are an issue.
In addition to my L663 D240 First Edition I also own a 2022 Mini Cooper S E (the all electric one). The Mini’s BMS monitors both the movie I’ve HV battery and the 12v “services” battery and will not allow the 12v battery to drop too low, it will allow some charge from the HV battery to be sent to the 12v battery. I know that there have been a lot of issues with Ioniq5’s discharging their 12v batteries to the stage when the central locking cannot operate so they don’t have a smart BMS. Also if you look through the menus in your Tesla’s big screen I think you will find that it has a camping mode that allows the heating to cycle at night in cold weather - it might do other power saving thins to to reduce the load on the 12v battery with the car not being allowed to go fully into sleep mode like switching off the surround security cameras and other unnecessary things. I used to have issues with the battery in an L320 RRS TDv8 that would flatten its battery quickly if you left the tailgate open - that was fixed with a software upgrade. Could the answer to camping in the L663 be to stick masking tape over the courtesy light switches on the doors and tailgate to trick them into thinking that the open doors are closed ………
Hi Tim - some interesting points. The Tesla does release power from the HV battery to top up the 12v battery much like your Mini. There are work arounds we could do on the Defender like disconnect the fuses / unplug the infotainment system but 120W of power consumption is a lot ! Also i need to be able to lock the car as I normally have the drone and other equipment with me that i need to lock in the car.
I had this issue on my Renault Grand Scenic last year whilst listening to music for an hour, sat waiting for my daughter to finish her riding lesson. I took it to Renault and they also found an electronic handbrake module problem. They replaced the battery and all is good. I'm amazed at how much we think we know about cars (I have had four defenders) but cars are so complex!! Love the channel, currently looking at a 110 at the moment!!
They are complex - complex is good but they still need to be efficient.
No fix for this problem?
Not that i have yet - although i am still looking in the CCF files
Inferiortainment maybe but I can’t see JLR ever getting to grips with full electric
As legislation moves towards banning fossil burning cars in 2030 all electric will be one of the main options soon !
Interesting video.
I have gone the PowerStation router for camping. That way it can run setup interior lights and exterior lights etc with out really touching the vehicle battery.
Thats a good idea but even with a powerstation i would have the same problem - just be opening my doors to access my equipment etc
At least with an ICE car you can start the engine to charge the battery, with an electric car then you could well end up stuck.
Hi Steve - Indeed - although you have a lot more power with an electric car - so you have 80Kw in a tesla model 3 - the land rover battery only has 96x12v = 1.1Kw
Out of interest, what is the biggest capacity battery you can put into the new defender?
Hi - not sure - i guess size is the only limitation
Great idea 👍
Good information 👍👍👍👍👍
Thanks
Damn Infotainment systems
To be fair the infotainment system is only doing what its told to do !
👍👍👍👍👍👍
I guess 10 Amps
I was correct 😂as that is what a 2005 LR does!
Spot on !
I’m not sure it’s just for speed. The 2005 would boot up the ICE on unlocking just to show a bloody LR logo for 10 mins and drawing 10A. Locking the car would not shut it down! Crazy !
As you can tell I think there is some real room to improve power consumption here - with modern electronics 120W is wild. I have my theories on this ... Apple devices are the shining example of how to achieve fast response and low power consumption....but this requires a lot of integration of all the modules into one silicone IC !
