The proper way to build a battery is to have more serial connections between the cells. You have all the cells connected in parallel with a nickel strip on both sides and then just two strips to connect it in series. Those two strips take all the current. Better to connect each cell in series and then connect all of them in parallel with one, possibly even thinner strip. Parallel connection is just to keep all the cells at the same voltage and it carries minimal amps
You wanna install a parallel charge cable that is routed internally.
That way when your out and about you can leave the Twizzy locked up and charging so that when you return not only has the car been topped up 10-20% it's also been nicely warmed up by the inverter ! Win Win :-)
Matching the main pack voltage and using this as an extension would be a better solution, your losses with the DC - AC - DC conversion would be around 30 - 40%
Shame to lose it as heat rather than get extra miles out of it, your main BMS will probably need rethinking but I'm sure it would be worth it
This concept would help with commuting in a cheap short range EV like an iMiev. If there is no charge point available when you get to your car park, you can trickle charge from this auxiliary pack instead 😎. For example, the public charger in the street where I park near work has been out of order for days 😱.
interesting idea. You could keep one of these on charge at work tucked away under your desk and when you arrive in the morning just take it down to your car. Put it back on charge before you go and do the same the next day.
Yes you could!
Fantastic. Consider maybe routing a semi-permanent charging cable along the floor and into the back seat with a chunky switch on it, so all you have to do is switch it on, and not run the coily cable through the door... Great project though, loving all the Twizy mods.
Did you ever thought about doing straight injection to controller from your spare battery? Obviously lovering the voltage to 57v. So the twizy could take charge thinking as its regenerating? Faster! More efficient!
Yes it’s not entirely straight forward because the BMS controls everything in the battery box, if it suddenly sees a strange voltage trying to charge the battery it will throw an error on the CANBUS and shut down! I have got a new custom BMS to install in there but it involves taking the battery out and apart and I just haven’t got that far yet! The issue is I enjoy using the car so much I just don’t want to take it off the road haha!
@@andykirby you got me wrong a bit. I spoke with keneth twizy box maker, and he said that it can be done through motor wires, as i said it would think its regenerating, so wouldn't ne a problem with bms, as its controllers work to take charge and send bms. I hope one day i will find time for this type of project. Imagine 200amps fast charging? ;)
Ah yes, in theory you could do it like that but you would have to make sure the car was in Drive whilst charging and be very careful not to put power to the sevcon terminals when the car is off otherwise it would probably fry the controller 😁 i know others have done this, I’’m not convinced it’s a full proof solution.
@@andykirby oh so you know personally who done it? Would love to chat to that person. 500amps diods to use, to be sure its not gonna fry ;)
@@eddieeddie7715 Where exactly would you put those 500A diodes?
i wonder if theres an aftermarket replacement battery pack available for the twizy that keeps all the original stuff working
Another great video Andy! Can’t help but feel this battery project will morph into a giant battery that lives in the back of the Twizy for a mega range extender.
I am seriously in love with that tuuune! That and the rest of this upload makes you the coolest Twizy driver out there.
Consider yourself as one of the true and mad eco-car nutters and hypermilers. People long talked about packing an auxiliary battery. It seemed prohibitive for even the i-MiEV owners who were known to tow VW Beetle REx-generators behind them. This is pretty practical proof of concept.
If Renault is building their Twizy 2.0, they should be damned to not source you up!
Haha thanks for the comment 👍 which tune do you mean? The one at the beginning?
I want to know why the twizy costs 7k+ when can buy a
Baojun E100 Electric motor-29 kW, 81 ft-lbs, top with real doors and windows
TWIZY costs 7k when you can buy a 2 seats Baojun E100 Electric motor-29 kW, 81 ft-lbs, top
speed-62 mph Range-100 miles (160 KM), Price-$5300
only costs so GDP 4 THOUSAND pounds
19:50 You invented the perpetual Twizy 😂 It charges self plugging like the meme
Could you not use a Tesla battery instead of the Twizzy's battery pack ?
Fun video, I would use a more substantial box though as you have to think about protecting the battery and also protecting you from the battery if you are involved in a crash, the last thing you want is an accident and for that battery to break free and possibly hurt you or start a fire, particularly if you cant get out of the car, your insurance company also might take a dim view of you driving around with that in the back, not being a killjoy as I love your videos and this is a totally brilliant video I just dont want you getting hurt, even low speed accidents can be very destructive and abrupt, take care Andy.
Also get a proper crimp tool for the Anderson connector and the ring lugs, soldering offers no mechanical strength between the wire and the ferrule and can be a potential source for poor connections esp when being used in automotive applications, I got my crimp tool from powerwerx delivered with a batch of Anderson connectors.
Hi mate, yeah I hear ya! Better box and perhaps cell fusing could make this safer, as well as a better way to secure the kit in the back.
Good tips about the crimp tool, I will look into that.👍😁
Excuse my ignorance here, but what would happen if you used a high amp 12v car battery & a suitable inverter... would that charge the Twizzy any amount ?
No it wouldn’t give any useable power because the twizy needs 2200W to charge, at 12V this would be 180A without losses. A car battery would not deliver this power for very long, maybe 1 minute if your lucky! This gives you an idea of how powerful lithium batteries are. You would need about 3-4 car batteries (ideally wired in series) to charge the twizy.
This is so like the days of the 70's Bond Bug when all you wanted to do was scoot about in an insane but fun like manner.
It might make sense to essentially hard-wire a cable through the car to the cable box under the "bonnet". So all you do is pop the flap, and plug into itself (or flick a switch). You could then shut the doors etc and it would be more secure.
Also i know its a proof of concept but if you build a nice box that fills the shape of the seat a bit better, paint it black, etc, it will look part of the car, and not stand out.
well done and really a great idea ;-)
Great job, would love to have one for my Twizy. What's the total weight including the invertor?
Hey ho. Well done mate! A word to the wise though. You are pushing toward the limit with those cells, I have a pack made with 26F's they are rated @5A max so 2,5A constant per cell. That means that your "P" can handle 35A constant, so you have 5A to spare.... That is constant current that I am refering to.... Not to shabby at all...... Nice one Andy good on ya....
Hey man! Yeah I realised they were 5A cells max, interesting they don’t really get that warm after an hour or so at 30A. It’s crazy how much energy is in that pack. I just need to find “creative” ways to charge it 😁
@@andykirby hey Andy, yeah creative indeed, without that bms its not so easy....... Look you can still pull 35A CONSTANT, remember the 5A per cell is MAX and 2,5 CONSTNT so they should not get warm as you are not going above the constant max, so your all good. I mean you could theoretically run your fridge on it IF the invertor can handle the startup current needed to get the compressor running, that is the drawback on invertors and appliances like fridges............
Heating Socks. I just saw it the other day and think of buying it. It would be also an option to drive the Twizy in the winter. Does only need 5 Watts. Regard max
5 Watts won't do jack shit though. 15 would be fine and then taper off towards 5 as you get warm.
My heated seat pad is about 15W and it is perfect. Heated socks would be good too, although might get annoying having to put them on just to go out in the twizy and then walk around the shops with them on 😅 I have heated gloves for my ebike, couldn’t ride without those in the winter.
why you need invrter? why you dont do DC to DC charging? it will more efficient ... your inverter consuming 20% of your batery backup pack .... any way nice idea...
The AC charging system for the Twizzy battery system is already in place and works well. Theres little point re-inventing the wheel by bypassing it. If you can feed it AC it will "just work" either on this battery pack or on normal AC. Simple. Otherwise you have to start pulling apart the twizzy at quite a low level which runs a high risk of damaging something.
Maybe feed the charger with DC? Usually they run on DC too just look at the input circuit
Fav thing with twizys.... Draw crowds all over "what the Ffff is that...." Fav comment!
Hi Andy if you buy a roof rack you can put the extender on it lol.On a more serions note I hope you got some heavy duty fire extinguisher and some fireman glooves!!
Nevertheless a good technical video quite interesting especially those 26f Samsung's.😍❤Happpy Xmas mate....😉
Could you review the car as a whole, I'm looking to buy one but no one seems to have the knowledge you have. I'd really like to hear your opinions on this?
Hi, if you’ve been watching my videos you will know I absolutely love the little quadricycle! It’s certainly not for everyone and I would only drive it with a powerbox fitted (I had it for 2 hours before I installed the powerbox) also you will need good windows like Twyrain windows as the standard Renault ones are junk. Finally I would try to buy one without a battery lease as it’s just stupid having to pay £30-40 per month to lease the battery. If you can get around that and don’t mind not having a heater in the winter (even though I built my own(another video)) then just do it! You’ll love it!
I wish the twizy had a 10-12 kwh 18650 battery in the first place, and some semi-fast charging and type 2 capability.
That’s my plan eventually! It’s doable.😁
May I ask why you can't upgrade the existing battery for extended range?
You can and I’m working out the best way to do it. There’s space for a little more battery capacity(range) but not a huge amount without compromising the battery construction.
@@andykirby Thanks Andy. You're the man! I look forward to seeing the video.
Bought a 100w wired iron from maplin for dirt cheap once and it was nice and chunky! If I let it heat up too long it would start glowing red!! Too much for pcb repair but perfect for large copper cables
the 18650 battery are bad for multi use without balancing each cell to cut off when charged, you'll get the middle cells warming, which in my eyes is a bad idea when temps can get high while discharging
Great idea mate and glad it worked well for you!
Let us know if any updates get added to the BMS you have on your site.
As built, the battery looks ideal for an eBike i.e. compact, delivering occasional peak loads but far from ideal for high continuous discharge to top up the Twizzy, as it has no provision for cooling of any sort whatever...
Not entirely true😉, the Samsung ICR18650-26F cells in this packs are fairly low discharge cells, 5A max so they are best suited for energy storage rather than high peak current applications such as powerful ebikes. Cooling is not an issue in my tests so far as the temperature didn’t exceed 30 degrees at the end of discharge nearing 3V per cell. Cooling is tricky to do properly as you end up cooling some cells rather than others which causes problems in itself. You might as well allow the cells to do what they want to up to a point and then cut off discharge if the temperature rises too much. This is how powertool batteries work.
OK - the cells are specified between 9 and 18 mohm so at 5 amps draw they will each dissipate 0.3375 watts or about 95 watts in total. That's quite a lot for a sealed pack if you run it for an appreciable time to charge the Twizzy - or do you disagree ?
We are drawing a max of 2.14A per cell for a total of 30A across 14 parallel cells. Also remember you are battling against the ambient air temperature.
LIKE for using red connectors on the minus pole
Sometimes you gotta just use what you got!🤐
Great. Needs two 'thumbs up'.
so I want to charge my ENV200 with this inverter .......advice ? ..............battery required?
Basically this prototype range extender can charge your car for about an hour, just the same as if you had plugged it into a consumer socket (slow charger) so whatever range you get from an hours charge at home you would get from this device.
The new ENV200 has a big 40kWh battery, this battery is only 2.6kWh so you may only get about 10 miles extra range with this battery not taking into consideration any inefficiencies.
I reckon a sensible extra battery for the ENV200 would be around 10kWh.
The inverter will be available from our store soon. I’ve been doing a lot of testing on it.
Nice one mate, no faffing around with the Twizzy electronics either :) This would also be good for work places that don't have charging points. You could leave the gadget charging under your desk overnight at work so it would be full to charge your car up the next day to get you home :D
That is EXACTLY the sort of thing it would be useful for! Free energy. It’s not that big so it could be charged anywhere really.👍😁
I think that maybe called theft. Not fee electricity, there is no free electricity. Nothing is free if it's man made.
@@chrisredfield3240 Would only do this with the employer's full consent of course. Goes without saying :)
@@zenzen9131 i can't even get my boss to pay me for the next day if i work through the night and have to sleep the next day.
Chris Hart Damn that's no good !
Great video, one thing that springs to my mind 2kw 240v fan heater, toasty?
Yes absolutely! I think 1kW would probably be enough actually, then it would run for 2 hours 😅
Need to work out a way to charge the pack when the car is being charged!
You'd have to add climate control then... In the house he's fine because he's charging at like 1A but in a box in the car overnight or something it might get too cold to charge properly.
great to see new video Andy 👍 love your content and channel 👍you must open the twizy and show us the battery 🤪 then make a bigger one 👌
Will do soon! Thanks 😁
could you use one of those power packs which charges all your devices when camping. worth a crack but they are expensive most decent ones about £500 / £1000 already have a uk plug port in it, so i was thinking charge it at home take it with you when long distances put it in the back seat or in the small boot in the back what the new twizzy cargo has, not sure if you would need inverter just plug in and charge, or a small pertrol suitcase generator for emergencies just plug ?
Could a 12v car battery be used with the inverter to do the charging. Than the 12v battery could be charged with solar panels when it is drained. I know this video is three years ago but I was hoping you could reply. Thanks
By the look of your shop, it is obvious that you are at least at electrical engineering level in your qualifications. Then you must also realize that this is as wasteful as charging a phone with a power bank? What would be better is to make a range extender by matching the number of cells in it to your vehicle pack and just add a high current two prong connector to piggyback it directly on your pack. Then you would not need to park while using it and the load on your original batteries would be lower when driving adding further to your range. I'm guessing you'd get 30-40% more energy that way instead of going from battery over AC inverter to EV charger to battery. It would also be a much cheaper product to produce as you'd only need cells tape and BMS, if this is a commercial idea.
I think u'll find its not as easy as that...
The traction battery uses contractors & is controlled by the CAN bus...
If the system sees HV on when it shouldn't b it will think there is a fault & the engine fault light will come on.. & u won't b able 2 drive it & could result in further problems...
I know as that's what I want to do as well & have been looking into what others have done & found out...
U need to find a way 2 turn it on & off (using the CAN bus or some other way eg manually) with the traction battery.
I'd love to see him do that.!
Having said all that...
Yes u are right it would b much better that way & u could recharge it from any charge point even when ur out making it a true range extender..!
@@MaxMax-dq1lu Excellent info, But I was talking about directly to the battery before the main relay? Is this difficult, because the contactor is built in the battery pack? I do know that connecting it after will puzzle the board computer and you would also have to be sure the booster pack is close to the same voltage when you plug it in, otherwise, sparks and a welded connector. But the idea is to leave it in permanently if you never use the back seat or only on longer trips, so you should be able to match the sate of charge when connecting, then it would be charged normally with the main pack, and the computer would be none the wiser. What you could also do is get a second relay and parallel it to the existing relay, so that booster pack is switched on and off together with the main pack.
@@Tore_Lund No worries buddy...
I didn't think about directly connecting the batteries as that would entail a load more work...
Battery off vehicle, open up the battery pack, make holes in casing, weather-proof the holes, etc.
I guess it could b done on a relatively small EV like the Twizzy but much harder to do on mine (Peugeot Ion) or any other full size car EV.
Please see my other comments...
Usually the charger runs on DC anyway just try it, the rectify it anyways
@@kitecattestecke2303 Yep it should as it must be a switching power supply in that charger. So he should rather make a 230V DC battery pack and plug it in directly without an inverter!
Toyota had a system like this for the Japanese prius solar roof. This would be amazing connected to any evs roof solar panel.
Great video Andy, pleased it all worked.
Can you connect the extend battery to main battery of twizy as series? So you can charge and run extend battery both at same time
I want to buy one BUT do you need a charging station. Or can it use a 120 volt outlet
Question for you Andy, Instead of using a battery to recharge a battery, why not get a second Twizy size battery and connect it in parallel with the original battery. Then both batteries will charge off the mains (OK it will take longer to charge) and give yourself longer range before needing to charge?
John
Hmm, it’s a good theory but the electronics and battery management are complex and you can’t just connect a second battery in parallel. Not to mention the interconnections and wiring would need to be capable of 450A which is what I’m currently pulling from the battery in the car under hard acceleration. I do plan to make a bigger battery eventually, maybe higher voltage to make it go faster 😃
@@andykirby u could quite easily parallel 2 batteries & the required control connections (or a manual switch to turn it on & off) ...
Also u wouldn't be pulling 450A as it would b half from each battery..!
Can you run the electric car directly of the inverter on road?
That's proper smart mate!
bro you was in harlow dude lets meet up
I'm assuming you have to max out the Twizzy to get it to motorway speeds. It goes faster than I thought. I thought it only went 50 mph.
That was awesome mate. U made all that look very easy but I know that working eith cables and connections that big isnt so easy. Really well done mate that was great. A charging cable inside the car would be better for security. Cracking idea tho love it.
Hi there how made you the battery back and how much was it.
it would be even more great if the there would be a way to connect it to the DC-side of the charger....
Hi buddy... Love ur vid...
It's a great idea, but it's less efficient than linking straight up 2 the traction battery.
Though I think these cells may not b the best choice 4 that... it would b interesting 2 see how they cope.!
I know it's way harder than most people think... but if any1 can/should do it... it's got 2 b u mate... if only to inspire the rest of us.!
As the traction battery uses contractors & is controlled by the CAN-bus...
If the system sees HV on when it shouldn't b it will think there is a fault & the engine fault light will come on.. & u won't b able 2 drive it & could result in further problems...
(I know as that's what I want to do as well & have been looking into what others have done & found out...)
U need to find a way 2 turn it on & off with the traction battery (using the CAN-bus or some other way eg manually or find the ecu's control signal to the contractors & use that 2 switch ur pack).
I'd love to see you do that.!
It would b much better that way & u could recharge it from any charge point even when ur out making it a true range extender..!
Best wishes...
PS. What inverter is that & how much was it...Thanks.
Thanks, and basically YES to everything you said 😁 I will be looking into this more, the correct use of contactors is VERY important because the speed controller in the car must not have voltage present during charging or it will fry. The system in the twizy is well designed and you can’t just bend the rules! Also just paralleling is no good because you have no way of controlling the current flowing between the two batteries. There’s a lot to think about, basically it’s like making a DC charger.
Thanks for the comment.
@@andykirby Thanks 4 ur reply...
Looking forward to u doing a direct connection, it will make an interesting few videos (the doing, testing various battery packs & the results/comparison/round up)...
If the 2 batteries r @ the same voltage (or very close) there will be little/NO current flow between them...
Great , looking forward for new stuff, I have an old Nissan leaf and it sucks, I can't use it to go far :(
You created battery to charge it.thats fair. But you can charge it directly from solar panels and inverter, without batteries? No matter the time, is possible to charge it directly from panels and inverter that no need batteries to work?
You can do but there's a battery management system (BMS) that controls what goes in and out the battery so its not completely straightforward or safe to di this without extra contactors
@@andykirby bms for battery?? I dont think so...if you charge your smartphone with old usb charger giving 0,5A-1A, it wont charge?? Of course it will charge but more slow. This is the idea.
...not very electrical minded but like what you are doing. Forgive me, but what is a BMS ?
You should not turn on your twizy when you are charging! There are some hints , that the charger of certain generations can get damaged by this.
2015-2017 are problematic.
Could you make a mini charge converter that would fit on a bike rack for an ebike?....is that even possible!!
Blowing up no problem live dangerously 👍
Please try on zoeQ210,tell me if is ok to charge a Zoe with the same inverter and a bigger power pack.Thank you.Miti Zoe driver Vienna.Look please for Renault Zoe 2500km trip, on you tube.Pace
Hi, yeah you could do, you’d need a much bigger battery for the Zoe to get any useable range.
You can put 6 cells in that Dyson or get a 6cell battery it will work on full power like the Dyson with the power switch button
Really? Interesting! So it can handle 22.2V no problem? Did you try it?
@@andykirby yes no problems what so ever
The motherboard inside is designed for future Hoover's wich they did and added 6s battery and a switch for the 2 speeds.
I have been fixing Dyson cordless Hoover's for some years and I know all the secrets.
I have 2 videos on my channel how I added extra battery and battery meter
Very cool😁 sounds like you’ve got a good business there! I’ll have to try 6S on that hoover, I still think that yellow one is better than the V6 that I’ve also got in the house.
@@andykirby if you want better performance from any cordless Dyson just remove the second filter...It's gonna be a bit louder but will have better suction...for the shed,garage or car the second filter is useless reduces power and battery life
grate idea love it what type of battery is 18650 cells?
Yes 18650, they were in something else before this so they are reused cells which makes it much more cost effective.
How would you rate the inverter? I’m actually thinking of doing something similar.
So far so good, we will be selling them in our shop soon with worldwide shipping.👍
Good stuff, how about the battery, i cant seem to find many 72v batteries for a good price, i have emailed ebikebatteries. Just waiting for a reply.
Email me on andy@cloudsto.com
Hi i dont know much about the twizy , can you not get a battery pack out of a smashed car and do away with back seat to double the range?.
David Macdonald something to look into
Question i have a twizy aswell does it need 2000 watts to load or does it load with lower watts greets from germany
Andy, i might do the same! Had this idea in my head!
great stuff....thanks
Great job thanks.
While cool you lose like 10-15% through the inverter and then more through the AC->DC converter/buck/boost stage. If you wanted to be super legit you should figure out a DC-DC converter that can match the cars nominal voltage :-)
It’s very true and was always at the back of my mind during this project however it’s pretty difficult to interface directly to the battery as you have CANBUS, BMS, various contactors in the Twizy, it’s just as advanced as any other modern electric vehicle so to do it properly would take a fair bit of work. I will probably build a battery for the car eventually 😁
True, but you would need to have access to the battery's main terminals.
If Andy built another big 14S pack with its own BMS, then he could connect it to the Twizy's battery directly and increase its range. It might confuse the computer's range calculator though!
Still, it's nice to have a separate mobile multi kW battery - he could rescue other EVs with it too.
Hi can you give link for this inverter Gobor 6000W
Yes it will be in the store soon 👍 www.cloudsto.com
@@andykirby i´m waiting to
Hi Andy what a great video. I finally get my new Twizy next week and of course one of the 2 disappointments with a new Twizy is NO power box option and the range this winter( they don't seem to have improved the battery performance). I also have been thinking of range extension and I looked at my i3 which has a built in range extender ( a small built in petrol generator)so I bought a honda suitcase generator and I thought I would carry that on the back seat, because I live in the country there are very few charge points. But this Idea of yours is tons better. Once you get it right, I for one can say that if you put it in your store I will have one. Just one point why did you choose such a big 6 kw inverter I have a 3kw Victron inverter on my boat that is much smaller and that will run a kettle all day long ,wouldn't some thing similar do the same job? looking forward to further vids on the Twizy Well done
Hi, actually I believe you can now run a powerbox on the later models! I reckon your generator will work well as long as it can provide 2.2KW continuously and is pure sine wave. I’m seriously thinking of offering this as a product so stay tuned 😁 the reason I used this 3000/6000W inverter and not a victron is that this inverter can run from 72V which means the current at 2200W when charging the twizy is about 30A, on a 12V victron it would be over 200A and that just isn’t a good idea😁 victron only go up to 48V for their 3000W inverters which is a bit too low for using with a small battery... and they are VERY expensive too 😁
There is little harm in having a bigger inverter than you need the power drawn only really relates to what you draw. Most inverters are disappointing in what they actually deliver. Some of the lower rated inverters can do a bigger start up than higher rated ones for hoovers ar mictowaves etc
@@chrisredfield3240 hi Chris . Yes I was just thinking of the physical size . Would be a great idea to conceal the cells about the twizy (if you could find a place for them)and then if the inverter was not so big it may be feasible to install that some where?
@@stevea5407 wonder how well a small diesel generator would work out using red diesel.
@@chrisredfield3240 I think it would work ok . But any genny would attract attention, then there is the noise and of course you'd have to chain it up or it would be gone pretty quick, you would have to stay in attendance throughout the hole charge. With Andy's idea it could be concealed in the back of the Twizy no noise and you could go for a coffee ( great idea)
Could you check how it works with the compressor 24 liters
Should work just fine, those compressors are about 1.5hp right? That’s fine continuous but would need to check the startup power.
Can you drive it while it is charging?
Genius !
Thank you
Do you charge the battery pack with the hyperion eos?
No it can only charge 14S maximum, I use a cycle satiator or one of my other chargers, I’ll be doing a video about it soon.
Why is he using a SpeakOn connector O.O
Hi sir
Can the vehicle be charged while travelling?
No it can't.
@@andykirby I wonder what is the root cause of this
i like the twizy
Brilliant!
Cutting edge bro!
who would thought of that !!! if you putt on more battery's you could drive further
well done...
Imagine it on bicycle !
Prix ?
Great vids love em...
Couldnt you plug it in to the Twizy in parallel ? seeing as you'd be carrying it about anyway.
Or would be that be too much complication ? and not compatible with the Twizy BMS setup ?
Yes I’ve thought about this a lot. You can’t easily parallel lithium batteries of different types with the BMS, contactors and CANBUS, ECU etc not to mention Regen braking current going back into the battery. The Twizy is a proper electric car and it will throw up errors if it sees a voltage somewhere it doesn’t recognise. The charger is also controlled by canbus and talks to the BMS. I’m trying to learn more about all this so I can eventually build my own battery.
Check out the scoot company for me. I made a perches and I was told it’s a scam. There selling your twizy stile car for reduced price ‘s . Are they in business or not. Am I getting scammed or not.
Andy that is amazing 👍
DC to AC to DC.... Let's think about this for a second.........
No of course its not the most efficient way of doing it but it avoids wiring direct to the traction battery and dealing with BMS, contactors etc
@@andykirby that's the fun part, figuring out mayhem. Nothing like PnP. Either way. Keep having fun!!!!!

Don't listen to all the nonsense about DC-DC conversion 10% loss blah blah. What you have made is a FAR more useful device. You can power pretty much any mains powered equipment anywhere you want to. Campers, caravanners and boaters would love to have this (although probably not at the price it would cost to produce it commercially). Then there are farmers, builders and who knows how many others that need mains power and don't want to use a massive generator.
The only mods I'd make would be to stop it getting stolen!
Cheap small generator
Yes true but I don’t think that would go down well at a car park, also you still need a pretty big one to kick out 2.5kW continuously for 2 hours.
