I'm not really worried about the traction battery. I'm worried about all the other components unnecessarily packed into the modern car (not exclusive to EVs) that may get damaged or fail and incur significant repair costs. Unfortunately I live in California where the gas savings from an EV aren't that significant.
Inflated costs due to over-regulation, high interest rates. People don't have $100k sitting around, especially people looking to cost optimize their commute.
A hundred thousand? For home solar? In the state with a direct line to Chinese panels? In a liberal state that is desperate to get carbon neutral? Where you have fantastic year round sunlight?
Yep. BOM is about $40k, but the barriers to DIY are artificially raised. There is nothing complicated about these systems. It's a buck, BMS, inverter, and load switch.
