first stages of pulling out the battery to fit ours - To support the Twizy Roadtrip and be rewarded with some 'Working Ink', go to www.indiegogo.... OR to buy materials for your own experiments, go to www.workingink.co.uk.
Appreciate the strip down and that you were working this out as you went. Just for others reading, the Twizy is designed for the pack to be replaced from the underside so removing anything from the top is not needed just to get it out. Might be worth adding to the description so saving others doing a strip down just to get the pack. Great video mate.
As a someone without a drive, I wonder how easy is it to reconfigure the vehicle so that the battery is taken out to charge in the house in the evening and slot it back in the morning
Of interest may be a set of plastic trim tools similar to those made by " Bojo". They very cheap on eBay and invaluable for stripping down without doing damage to trim. Can also get a fastener popper, like a pair of pliers with veg jaws that open when handles closed and they pop out fasteners without breaking them. There a whole science to stripping trim off without doing damage,worth learning as can get quite costly!
The Twizy is such a rare vehicle your struggle to find much information on RU-vid and they did a battery lease which was very expensive so it killed the Twizy almost instantly otherwise they would have sold hundreds of thousands
Ouch, this is bleeding £££ every month it sits "^Price excludes mandatory battery hire from £45 per month, based on 4500 miles per year, 100 excess miles £3.75 including VAT. You will not own the battery"
From memory the only place you could buy a Twizy outright was Norway for about £11k. If the Chinese near copies ever come here I'll buy one; the Chinese have even invented things called 'doors' which would be handy in the UK.
You could have read about how to get the battery out on the german Twizy forum (www.twizy-forum.de/), but you made a nice video along the way :) The bottom bars are actually an integral structural part of the battery case, they are designed to absorb energy in case of a crash. They are massive, some have replaced them by aluminium versions to save weight. For the standard replacement box Klaus is working on, he thinks we can achieve enough structural integrity also by another case design. As you're only risking your own battery I think you can omit them and use the space gained for cells (if you build your own case).
As far as I read an E-Car needs about 20 KWh for 100 Km by normal size. But I think with the tiny twisty it will be less - may be 10 KWh per 100 Km only. And ... a Battery with less weight causes even less energy.
I wonder, if you ever will get all the parts together again... Lol... not like me, that will have 50 % of the screws left, if I rebuild the device again...lol..
I would rather go with pouch cells than power blade as it takes too much of space. May be it can be implicated in future demos but for this one the world is watching. So save up some space and use as much as battery material as you can. I for one hope that you guys nail it. This world needs innovators like you guys and go down in the history books that changed the world entirely. Cheers mate and good luck.
Yes, I have been wondering how much energy density those yellow cases on the blades will cost you. I think the concept of the blades is a good idea, but I think you should use a much thinner case for each blade. I looks to me that they don't need to be that thick to be structurally sound.
Missed the train.. All solid-state hybrid batteries with carbonaceous materials are now of particular significance. This is the way to go and get funding. Keep up !
Andy, your fan in the top corner of the bike box won't work at all, all fans need space on both the inlet and the outlet sides it is recommended that you leave at least one fan diameter of space for normal operation.
1:25 Did you mean 40kWh? that would be enormous, the Twizy has a 6,8 kWh battery. Also, pleaaaase be careful and don't mix up: - kiloWatts [kW] - which is thousands of Watts, which is a unit measuring an amount of energy being used (or produced) by second => [kW] = [kJ/s] (or kiloJoules per second) - kiloWatthours [kWh] - which is thousands of Watthours, which is a unit measuring an amount of energy (because you multiply the power by time). => [kWh] = [kJ/s * 3'600s] = 3'600 [kJ] (or kiloJoules) because there are 3'600 seconds in one hour.
Just to make a quick correction. The Twizy comes with a 6.1kWh battery pack, rather than a 40kWh battery that you mention in the video. What is amazing is that this small battery has a reported weight of around 100kg, which I guess comes from the amount of protection around the cells.
mechanic I have some useful information for you. About the twizy It's about the main nut. It is found on the drivers seat. It's called the owner😂 lol. Sorry I just had to 😂😂 I hope that you get a smile from this cheeky joke lol
Oh god, I hate those rubber stoppers Renault uses! On a more positive note thanks for the informative video, I look forward to seeing this project progress.
yeah could be - but it also plays a part in the centre of gravity - the twixy is quite high it might make it a bit hard on cornering if you reduce the weight of the bars too much
This looks like a wonderful little weekend project-hobby money maker idea. Pick up the Twizy cheap off auto trader. Replace the battery pack, give Renault theirs back and turn the Twizy around as a "No battery rental" I have seen a lot of people on forums say they would be interested in the Twizy if they could own the battery. Me being one of them. Yes, I understand if doing it as a business, they would likely send in the lawyers but if you are doing it as a hobby to a car you own, there isn't a lot they can actually do.
Hi there was this project never completed for some reason ? As i see this vehicle has not held an MOT since 2018, was there some issue with getting an MOT with the modified battery. Cheers regards Richard
I m amazed that they make your life not easy at all... a slider in the rear side of the vehicle would be logical and on electric overboard so you can bring 100kg batteries to your flat to charge at home if needed... no I m too logical... the overboard cost 200 euro only... they are french so they do not have the Chinese technology to create something easy to charge at home.
No surprises if you had visited your local panel beater before you started destroying the Twizzy's body! Or get Ed China ,his face is still famous and he hasn't had serious online work for a long time! Rob + Ed and you eat your Indigogo target! Ed even has a real garage and you can flog your toy tools on Ebay. Bloody painful watching you all fartarse around - Plus Ed would look better on the Twizzy and bike trials. And a lot cheaper than Richard Ayoade i bet! i am sure Ed's BBC standard expertise won't go astray either! Weight before and after the battery upgrade?
Great stuff! I'm looking forward to seeing your blade config going into that battery box. Also, I commend you on upping your video production quality - clear video imagery and sound IS important.
Hi Robert, excellent work. Keep doing it you are about to change the world! Just a small observation and I'm pretty sure you already thought about it. Are you not concerned about a fire on the batteries if using paper as the sepparator?
How do you release the orange high voltage cable from the rear of the battery as I can see a button you push in, a clip that looks like a tie wrap you push in & then the plas tourer cover slides to the rear but I can’t remove the Plug/connector Any information would be helpful. Regards peter Ps good videos bye the way 👍👍
There is a forked plastic tool to remove this 'automotive rubber stoppers" Screwdriver will damage them AND maybe your hands! Wheeler Dealer Ed China will show you where to get one.
could you just replace this battery with an 60v 60ah lithium battery? with its own bms? so you only need to connect positive and negative? thinking of buying a twizzy. i already have the battery
I’ll say this ! Lucky you guys have the grits it takes to get this project to succeed . I do believe it will require tenacity that you have proven many times over to have but in saying that you may need support in some areas . Very exciting and I would be looking forward to many videos of each step of the FWG Twizzy development . Great content you guys ! Cheers
fair play, my least favourite part of working on vehicles is the plastic parts, they are a struggle to get off, then bits snap off and they never go back as origional :o
Watching this disassembly, I'm reminded of what Princess Lea said to Han Solo while escaping the Death Star: "You came in THAT thing?! You're braver than I thought!" I've driven everything from small motorcycles to semi trucks with 3 trailers... I don't think I'd be brave enough to drive that on an American interstate. But seriously, you've become a great inspiration to me. I'll be converting a spare bedroom into a lab this summer. Thank you for all the wonderful work you do, mate!
Im not sure if he realised how rough he is with it all and using a screw driver on plastics parts is a no no considering that there are plastic tools for that type of job.
Did Robert accidentally state the capacity of the replacement battery? Eight times the Twizy's standard capacity would give a hypermiling range of around 400 miles, if weights were kept to about the same as the standard battery. A second one (or two!) in the passenger seat would give enough range to travel the whole journey on a single 120kWH charge.
Well done man! I wanted toave some information about the battery pack (I didn't trust the Wikipedia's one). The driver’s handbook says that the battery voltage is 58 V. However it does not tell some other specifications: Brand of the battery. Limits of voltages ( if SOC is low, there is a maximum voltage that is required, if SOC is high, there is a nominal value (probably 58 V) Capacity (Ah) Energy( KWh) Internal resistance Cycle of life. Weight (100 Kg according to Wikipedia?) Is it possible to purchase comercially this battery pack? Yeah, I know I'm asking too much information, but I might get these information from forums and the battery's manufacturer.
I see a pouch left and right in the foot-well. Looks exactly like my BMW C1-200 has. It looks serious the same kind of built as a BMW C1-200 .. The BMW C1-200 was made in Germany. Mayby there is a crossover somewhere.
They didn’t design it with ease of battery replacement in mind, did they! What a palaver for what could have been designed as a five minute job. At least nobody will be stealing Twizy batteries in a hurry. Thanks for the detailed video.
I'm sorry you were not able to meet your goal I only heard about it a few days a go and the same time I went to buy the kit but it was not available...i will definitely support the shop...again I am sorry.
Seems to me that a smaller version of the power source for the Twizy would be ideal for an electric ride on lawn mower. A rechargeable carbon battery would appear to solve many of the problems of the current versions.
from an engineering aspect having to rip apart the whole car to get to the battery says everything about renault... this is mechanical design 101 your machines have to be easy to assemble and disassemble
I really hope to see how to modify a printer to use the ink to create the sheets for the cells. As well as how to assemble the cells with how to make the ingredients, wire up the cells into the battery, with balance if required and charging. I've been wondering how it's all done ever since before the scooter! Congrats on getting this far gentlemen the twizzy is looking hungry for a new heart. Love all the content lately as well. I can't wait to get me some ink!
I've been wondering why you don't use a paint roller especially when I see that big roll of paper and the poor sod flailing away with that tiny paint brush painting an inch at a time. Unroll that paper and you could do about 20 feet of it in half a minute with a roller.61 m sq that is less than 700 sq ft. If you had a flat space to lay it out and fasten it down you could do the lot in a couple of hours. Let it dry flip it over and do the other side next day. Or staple strips to the wall like wallpaper and let me go to town. Give me a good roller and a broom handle and it wouldn't take 2 hours.
May I recommend purchasing a trim removing kit - plastic tools (mini-crowbars and levers) sold on Amazon or eBay - perfect for helping to remove the clips and plugs on a modern vehicle without damaging anything... Regarding 'dropping' (lowering) the battery - do make a simple fixture to bridge the double frame and add lifting eyes to the battery box - then you can lower the battery with a simple winch mechanism... Both these operations are obviously going to occur several times - so it's worth a bit of expense/effort to make the job easy by making/buying simple tools... Regards, MartinB - Gothenburg, Sweden
Very intresting Video. Not so easy to get the Battery out - on purpose?! And when I see the ceap plasic material ... Ugh ... However - you did not gave up. Well done! Now I'm looking foreward about your Battery - difference of weight and dimensions.
quick tip for your further sound technique: you can plug the mic with your smartphone and record sound parallel with your camera. Then put the sound file of your phone to the computer. There should be a mode in your video editing program where it automaticly synchronizes. (Better then having a long cable across the room)
I can't believe you had to take that much of the thing apart to get the battery out. It's a good thing you guys have the pallet jack, for that it is really the best thing to use. Hey, what is the volt and amp rating of 1 of the power blade cells and how fast do they charge from 0 to full, and how many amp hours are they good for? I can't wait to see the outcome of you guys efforts.
i know it's silly isn't it - ah well lol - as for the specs on the blade i am reluctant to release specs mate - just in case i make an idiot out of myself lol
It's what I call a knee moment, where a project moves onto the next phase. Really exciting times there at FWG and for us watching ! Congrats on a very enjoyable teardown and battery removal.
To take most modern cars apart we need more specialist tools than a snap on draw chest can take, I was impressed with the tizzy simplicity but it's quality shows in places, the main crash struture done OK in the ncap test so it's not a death trap and that's always a plus.
Hé bien pas de moquette nul par !pour le prix !Le siege un truc en plastique !En gros renault nous laisse faire l'interieur ! Voiture belle est mignone !Mais encore bien tros cher ! Vraiment dommage que la video ne soit pas en vf !
Hey interesting question, are you going to have to put some weight in it after you put your battery in? Because I'm thinking your battery is going to weigh next to nothing.
Hey, great video, wonderful platform for playing with big batteries! I notice the treadmill in the background. With that connected to a generator, how long would it take to charge the Twizzy from it!!! ;)
