This will definately be an interesting addition to the range tests
absolutely agree, great idea!
Top Bjørn, glad you are doing this test, so that we don't have to do it 😎
I have seen videos of Tesla's being charged and run by the Delta Max. This is the first time I have ever seen it used on a BMW i4.
One reason I like that power station is that it has more than 2000Wh of capacity.
I'm quite surprised that the Delta Max was portable enough to fit in the back seat of your BMW. Normally power stations of that size are quite big and heavy.
Great addition to your range of tests, kudos for having designed this new stream for us!
Great resource Bjorn, maybe spreadsheet the specs so we can see differences between cars, how they handle the deap discharge, power limits, etc.
I will
@@bjornnyland call it "how deep in the sheet" 🤣
@@Bud_Terence 🏀🏀's deep 🤣
Thank you Bjorn, for another great video. I truly love your channel and learning a lot here. Keep up the great work!
Great video Bjorn. It is very important to understand how the different vehicle manufacturers treat the low and zero battery situations...
This is exactly what I was waiting for; someone to test the Ecoflow for an "emergency backup" for EVs. Thank you Bjorn!
Love the BMW driver jokes 😂
And great quality content as always!
Absolutely great addition to the test suite. I am sure that each manufacturer has residual capacity to do two things: 1. Mask the hi volt batt degradation, 2. Protect the cells of the hi volt battery ( they don't like being completely depleted). That i4 M50 is very efficient as is the Ecoflow. Great vid!😁
How can you mask the battery degradation without change the voltage limits?
@@antoniofreitas6335 battery capacity is comprised of energy which is a function of voltage, current and time (kWh).
@@dondonaldson1684 i know it, that's not what i asked, how can you take more energy from the battery without change the voltage limits? Like, if you have 10kWh between 350V and 400V how can you take more energy from it without change the lower or the upper voltage?
@@antoniofreitas6335 what Bjorn and I are pointing out is the following: manufacturers are saying the capacity is "x" when it is really "x" + 5-10 percent. They are masking the degradation of the battery's capacity over time. Bjorn showed this in his test. I hope this is more clear.
@@dondonaldson1684 is very far away from clear, manufaturers limit the capacity by limiting the voltage, all packs are full or empty when they achive a voltage point, if you understand something about electricity you know that the capacity is betweenthis 2 points of voltage, you can´t mask capacity without moving this points, like Tesla did before in emergency situations and free the upper part off the battery, Tesla did that by moving the upper voltage of the pack by software, that's the only way to do it.. It's Physics, can't go around it.Or there's somenthing i don't see, tell me about...
Perfect acting Bjorn ! You made me smile!
I do like this test. The Ecoflow was a great choice as accessory. The 12v booster charger will definitely save your butt at some point!
Great video Bjorn! This is a nice addition to the list of tests you do. Very entertaining! I haven't seen you run out of juice in one of your videos in a long time except for the race with Pawl, he would have loved to have that backup battery!
Good idea, Bjorn! Looking forward to the DED test results of other cars!
Leaving the trunk open is also a very good sign to show that you are stationary (of course in addition to the triangle)
With a BMW, nothing is predictable 🤣
@@bjornnyland true
Great video. Please do more. Very cool demo of the Eco-Flow.
Great test to add in to the collection Bjørn!
Would love to see you do it with other cars as well. Like Model 3 and so on :)
The new zero hero! Awesome video, definitely one I will be watching again!
Nice addition to the tests. Now people will have an idea how the acts when it runs out of electrons.
This is a very good test! continue this for other vehicals as well please bjørn. Hope to catch up with you sometime in Oslo :)
Loved taking and using the Ecoflow to charge the car. Cool man!
Very good test, thanks Bjørn.
Great to see these tests to see how the car will behave at battery death!
Very cool and full of good information. Thanks Bjorn
What a cool test Björn!
This is awesome! Very interesting and reassuring to know how the vehicule behave. Please do this test with a Ioniq5!!! 🙏🙏🙏
This is very useful Björn and especially for EV drivers. Great video. 👍. Matt Watson on CarWow in the UK did a similar videos testing quite a few cars until they died. Very interesting how many cars actually went beyond the zero and by quite a lot of margin as well. Not sure in Norway if they have similar to the UK were many breakdown organisations now have on many of their vans electric generators to give customers enough power to get to the nearest chargers. But be good to add this to your tests as it will definitely help EV drivers what to expect if they breakdown. Sh*******t now you have test every car again 🤣🤣🤦🏻♂️
Great test to add into the TBTests !! Veerrryyyy NICE ! 👍
For your back, I'd advise keeping that battery unit in the open trunk and charging the car from there.
This is a great addition and unseen concept!
Staging the clickbait thumbnail was flawless. You’re a natural actor 😂
Great test. Thanks for that. Gives me even more confidence when getting low, that BMW built in some buffer.
You finally show your comedy.. good show Bjorn, Really!
Great video! Recommend not putting the ecoflow battery on the hot asSphalt when pulling high load. Trunk may be cooler than the heat soaked ground.
Very interesting new test procedure :) Love it 😊
👍 very cool new test procedure, great info! Can't wait to see the next cars performing below zero. How about doing this with a MEB car?
I look forward to Bjørn doing this test in January when it's pitch black, stormy and -20°C outside. 😁
Well done, Björn!
Thanks, its an interest test. Of course another factor is it might have 20km left in it at 0% but when its a few years old it may not.
Nothing like a Japanese eco ICE car though which typically have 50 - 75km left once the fuel gauge gets to empty - not the same situation for at least a couple of American ICE cars I have driven where empty often means empty (I have twice coasted into a fuel station in neutral in the USA with the engine stopped!) - who would of thought ;-)
Thankyou for this - reassuring that in the event of a charger being unavailable that a car will keep going for a little while. This test would be good with a product like zipcharge (I assume other products are also in development) which has specific functionality for EVs (native type 2 support).
Great new test. Very interesting and entertaining to watch!
Very Nice test, I think this should be implemented in your test program 🙂
Great test and very interesting. I have iX50 and i feel even more confident about range now. Even at 0% still can reach EV-charger
Love this test! Also for old cars!
Nice new test! Thank you!
You might start to not like this test in the cold seasons. ;)
Almost you have the battery calibrated now! :)
Great test. Just be careful doing it in the winter time.🥶🥶🥶
Mycket bra video Björn!
Agree with others this is a very interesting test and you should add it to your standard test. I appreciate that you also looked at the charging speed. We seeing why BMW gave you a test car without the latest 7/22 software.
Great demonstration thank you very much
Amusing and interesting stuff! Bjorn should be a comedian!
Even when stranded that car is good looking
Apart from the hideous 'beaver' front end
Agreed. One of the best BMW designs in recent times.
@@johnodell5310 I think it fits the car very well. It's an overall gorgeous car.
Good test. You should do a test charge at home for each new car, some don’t like the grounding arrangement of these units (I.e. there isn’t one) - do you know if it’s got ground tied to neutral to simulate a tncs ground?
"...also known as the BMW parking light..." hilarious :D
Great test 👍 please continue to do other cars one day.
Perfect test as always! How many kilometers would a Tesla MY LR go under 0%/0km? What would you estimate?
15:47 I think you also have to open the bonnet to show people that the car has broken down as I remember breaking down and occasionally people would honk and shout "you can't park there" when you are clearly broken down.
Great test, this is really useful info!
Nice 👍 A whole new level of battery nerdness has been reached
16:00 „Mein Auto is kaputt!“
BMW-Salesman: „That is not my Baustelle!“ ☝️😉
Great content! More videos like this please
As always, very entertaining and informative. Love your vids. And “Now I need to take click bait photo” LOL.
I have understood that the car AC->DC inverter uses couple of hundred watt’s. So that eats to the efficiency.
very interesting, make more videos like this with all cars
very good real life testing.
great educational video
Perfect idea. It can prepare us for the worst scenario and tell us what expected when we ran out juice
Bjørn: Can this Ecoflow charge up a Zoe with standard charging cable without trafo and generate this a TN power or it's generate only IT powergrid like we have in old houses? Typical TN is 0V between ground and N and 230V between ground and L1.
Great idea for a series
Great test :) Thank you, Bee Emmm Veee , for allowing Bjorn to do this kind of testing . We consumers want to know what happens when we are in an emergency low SOC situation :)
Bjørn, I was actually expecting Pavel to appear with a tow truck :) We haven’t seen him for a while already ;)
Very Interesting! Perhaps you can try it on an old Kia Soul with degraded Battery? I wonder if the BMS eventually miscalculates on a used battery, so that the car shut down before 0% ? That would be also very interesting.
Hi Bjorn, thanks for your great videos!!
Can you do the same test with the 500e?
👍👍
Interesting test. Odb scanner with cell voltage and cell difference would be nice at 0% or Dead on future tests.
Option for ventilated seats = priceless 😍
Wish Teslas had these for countries like Australia.
@@ad_fletch Unfortunately Tesla find it more important to put fartsound in the seats instead. As a non-USAian I struggle to se how that improves driving comfort.
I'm pleasantly surprised that the BMW uses Wh/km unit instead of kWh/100km! Very nice! Is this something you can change in the settings?
Serious?
14kWh/100km = 140Wh/km
Or... delete the k and put a 0 behind the amount of kWh
Rocket science? Noooooo
Yes
@@krisja2995 Bjorn has a video explaining why it should be Wh/km and not kWh/100km.
@@krisja2995 agreed, hard to do math in their head? Gheesh
@@dondonaldson1684 Not having to do the math is better
I was going to try this on our Leaf on an EF Delta (sadly, no app for this version), but the US version doesn't have a ground pin so the EVSE (Level 1 - 120V) won't activate. Any way around this? The EU version Bjørn has appears to have ground pins. I suppose I just need to bond the ground pin to the neutral somehow.
Hej Bjørn, can you also do some more testing with the bmw ix3? :)
I laughed so hard at the front open for the 'clickbait thumbnail' haha. This was a good video.
One more phrase for the vast Bjørn repertoire: Don’t be a zero hero! 😂😂
I had no idea Ecoflow "huge battery pack" even existed. Nice thing to buy in case people go camping for example.
Gas generator is better
@@eletrohitsbr You cannot use a gas generator indoors. Your "better" is not necessarily my "better".
@@KurtSeiffert just leave it outside and use a cord, a battery can catch fire easily
@@eletrohitsbr thats actually not true. Your gas generator can catch fire more easily.
@@eletrohitsbr And What about noise? Better for You and neighbors?
Now we're cooking. Nice one👍. Depends a lot of the Battery degradation. You could do this Test beside the new-ish Testcars, also with older cars, Teslas, Leafs, E-Golfs etc. Maby in combination with an Aviloo diagnosis upfront, so we can see at what degradationlevel of the battery, how much the car is getting under 0.
Dont be a zero hero.
Bjorn 2022.
PS love your vids dude
it is a beautiful colour for sure
Intressant!😍 Du måste göra det med nån av dom franska bilarna. Dom är ju knepiga😅
Going slow at low SOC is something I never understood, the only reason would be to check for over-discharged cells but the BMS should know that right away.
This test will be so much more dependant on temperature, and previous charging cycle.. the battery voltage on low SoC and the cell voltage difference is not really important for normal driving, but at low SoC this becomes very dominant. Cold battery could easily mean the difference of having 15km left on 0% or stalling at 2%.
Very good video. This is something everyone know.
Great test - thanks! Question for you: if you had an extra 3 kWh buffer on the low end of the battery and there is only a 3 kWh total buffer (84 kWh gross vs 81 kWh usable), that doesn’t leave much (if any) buffer on the top end. Is it possible that BMW is underreporting the gross battery capacity by 1-2 kWh?
Actually, it’s 83.9 (gross) vs 81.5 (usable), which is only a 2.4 kWh difference. I’m thinking the Germans have snuck in extra storage in this battery…
Most EVs with 400 volt architecture use a 96s configuration, meaning, how many ever paralleled cells are run 96 in series for a nominal voltage of 355.2 and full charge of 400 volts with each series paralleled module being 3.7 volts nominal and technically 4.2 volts fully charged. However, if the pack voltage is a true 400 volts fully charged 400÷96= 4.166... volts per cell, which would be slightly less than 2% top end buffer that is never used regardless of cell degradation to allow cell balancing. The car manufacturer may set a larger buffer initially but it would always end up 2% in the end.
Interesting video and test. It would be interesting to test on other cars.
Holy shit. This guy got a portable power bank for his car.
11:45 Going up a hill with no power left is really scary. This part of the video gave me bad memories on a eNiro with around 5 %. When the hill demands more than turtle mode delivers, your are DON. No way to recover from that, even if the battery is not DED yet.
This is probably the best test for EV range anxiety, now i'm even happier with my i4 purchase.
how much did you paid for the blinker fluid? Staying there with the hazards must be expensive on a BMW.
Don't worry. I have the paid blinker subscription 🤣
Very interesting test to see how a car acts when the battery is extreamly low.
Is it the yellow vest test? Nice informative test again, it's always interesting to visit how the car's software reacts. I guess they could always change it (OTA?) in the future. I saw on a Japanese pet Otter YT channel "Aty" that Otterman tested a similar EcoFlow unit with 4x Solar Panels whilst camping last year(?). Kettle, Microwave and freezer (for the otter's fish), maybe take a look there.
PS also saw a video in America using the EcoFlow to charge a car but there they needed some dongle plugged in to provide a neutral/earth for the USA outlets.
PPS If you ever get the chance to test the SylvanSport Go pop up camping trailer that would be cool, together with an EcoFlow ;-)
it's coooool! waiting for more!
Cool test, thanx for sharing! =)
Wow, that is very courageous of you.
What a funny way of the technology evolution: you have to convert low voltage DC source to mid-voltage AC in order to feed the car with high voltage DC, losing twice on DC->AC->DC conversion. And that is only because the car is not designed to receive DC below 500v and has no dedicated DC->DC 🙈
@@mattg432 well, sure, it doesn't. But even if it had, it wouldn't help: ecoflow internal voltage is 48v, max output is 220-240v, while ccs dc voltage cut-off is 250v. The only way to boost 48v to 500v is this weird 2 step 48->220->500v (in fact even 3, car does 2 conversions when is fed by 1 phase current)
Some cars needs to get over 1% to start again. But wil be fun to watch if the eco flow is to small at some point
