EVs depreciate quickly since the battery, which cannot be economically replaced, is not likely to be efficient or even functional after three or four years. Extremely limited market for used EVs. Range and repair issues remain huge. Even Musk has to obey the laws of physics. The whole concept had inherent problems and contradictions from the onset. Not least of which is that the electrical grid could never accommodate an American fleet that was 30% EVs.
“This Ultra-High Mile Tesla Proves That EV Batteries Last Longer Than You Think”

I have a Model 3 with 45,xxxx on it the SOH is 97% meaning in nearly 50,000 miles it has only aged 3% end of life is 80% by definition but that doesn’t mean the pack is dead it means it’s only holding 80% of its start of life charge. There is still years of life left in it. It is not a linear rate of decline for SOH the first 2% happened right away in 10,000 miles according to the BMS onboard. The last 1% was over 35,000+ more mkles. This is typical behavior for LFP cells. At its present polynomial rate of decline the 80% point will be reached after 500,000 miles. LFP cells have a 15 year calender life rating to 80% so that’s the EOL that will be reached first not miles. Model 3s in uber service have already gone over 350,000 miles with NMC cells and LFP cells have twice the full DOD cycle life times 3000 vs 1500. LFP cells also have a nonlinear relationship with DOD and cycle life if you only take them to 50% DOD you get 20000-30000 cycles not 3000 it’s a function of depth of discharge and C rate a 1C charge vs 1/2 vs 1/4 or fast DC at 2-3C rates. Mine never gets anything but a 1/4C L2 240v charge since it’s furthest trip is 65 miles one way to cowtown and back to the stable of vehicles.
Case in point I have two powerwalls not Tesla made but experimental from another company that I am torture testing off my solar system. Those banks all have second life cells in them from former EV packs that reached 80% EOL. I have been cycling them daily at 1/2C discharge rates for months now I have a nondisclosure agreement but I will say at this rate of use well above what even an off grid home would use no one uses 30kw in an hour for 2 hours straight. 30kwh is the typical usage in 24 hours for a medium sized home. Even then these cells SOH shows years of life left. They are in a separate steel enclosure because we are testing to failure they will go up at some point it should be spectacular. That’s the whole point test to the very limit and see what these cells can do.
