It’s insane that you can’t just DIY recell an EV battery with off the shelf cells. This could easily be made a trivial job.

- etrautmann 2y agowhy is that insane? Some have liquid cooling in between cells and high levels of integration. I'm guessing heat transfer compounds may be in there as well. Given the scale of what re-celling a whole automotive pack would entail, this strikes me as way out of scope for an average consumer, though I appreciate the DIY attitude and wish more products were made to be consumer repairable!
- _yb2s 2y agoSince cars are all more or less solving the same problem, hopefully it will standardize on a set of parts and procedures. I meant trivial for a mechanic- on the order of swapping out an engine. It would still be work for a professional mechanic or a skilled DIY person not your average consumer. You’d still be dealing with big voltages, toxic chemicals, and major chances of fire or overheating if done wrong.
- RevEng 2y agoYou can still swap out a battery just like swapping out an engine. Both require extensive knowledge, specialized tools, and a lot of time, but it's definitely possible.
- defrost 2y agoBoth can be done by highschoolers in the transport shop class.
- _yb2s 2y agoYeah but usually you have to get an identical pack- which is expensive for common EVs and nearly impossible for older ones. My point is these parts could be standardized with a simplified process to more easily recell any car. Batteries don’t need to be as unique to a car as engines do. Eventually I think EVs will last nearly forever, with the only major wear items being suspension and battery- both easy to replace.

- qwertox 2y agoYou want to share the road with a hillbilly driving at 80 mph who just hand soldered his battery pack together with the cheapest cells he could find on ebay?
- _yb2s 2y agoYes- I’m already sharing the road with people that DIY repair their cars. I’m an ex pro mechanic, most mechanics shops are in such a hurry they are not doing better work than DIY repairs. Your average hillbilly has been repairing things their whole life and knows what they’re doing.
- dns_snek 2y agoYou're alredy sharing the road with people who don't maintain their cars, don't have insurance, and people who could intentionally crash into you at any time, yet you still drive. This type of scaremongering is nonsense and does nothing except make corporate executives smile.
- qwertox 2y agoI'm pretty glad that maintenance and insurance are mandatory, and that most alterations to a vehicle require passing a special inspection. And it would be great if batteries, including their mounting frame and cooling system, were standardized in such a way that one would not only be able to let a shop replace the battery, but also have the option to buy a car without a battery and either reuse the old one or buy a new one from a better brand.
