It's no wonder when parked in a country that regularly exceed 40C that the cells deteriorated. A secondary issue is that the cell chemistry is very poor. --- End quote --- Yeah, and LMO could be acceptable when temperature is under good control - but the combination of no cooling and LMO is a really crappy one. |

And if they will go with it and people still buy it. It will be just an inspiration for other manufacturers. It is a sad world. --- End quote --- I wouldn't say they are anti-repair, that is where the company does things for no reason other than to block repair. But yeah, lots of issues with repair definitely --- End quote --- Every "How to design stuff" course I have been on have all emphasised ease of assembly over ease of repair. If Tesla have designed it such as they have a very low failure rate and a method for recyling the battery easily they could just have said "Swap the pack and recycle the old one" Then again, as Tesla know what that foam is they may have the solvent to get rid of it. Munro don't and haven't so have to do it the hard way. Given the energy involved in that pack it is one way of preventing unauthorised tampering. |

Munro himself claims in an older vid that model Y batteries are intended to be grounded down to a pulpy mess and then metals extracted out, how he newer detail as in his world everything is solved and Elon Musk is a saint. Now, metal separation are still cumbersome to do (read expensive) and its just cheaper to buy the various ingredients new from the supplier. |

--- Quote from: Zeyneb on August 13, 2022, 06:44:09 pm ---Yeah, I'm pretty annoyed by the ignorance of the babyboomers in my family buying electric vehicles because the media propaganda told them so. --- End quote --- The people I know who bought them did so because they are fun to drive and because they are so cheap to run. The Tesla Y my dad had would do 0-60 in about 3 seconds, that's supercar territory in a modestly priced SUV and 300 miles of range cost about $10 in electricity. I'd buy one myself if I drove enough for it to matter, I don't watch TV so it's not propaganda, I've driven one and personally observed how superior the driving experience is. |
