It depends on the EV model. Tesla battery replacements are way more expensive than with Kia/Hyundai EV’s batteries.
For me the decision to make one of our cars an EV came down to these points:
It was time last year to replace my wife’s car anyway.
Having one ICE car and one EV gives our long distance driving some energy security in that if the Dims mess up gas supply we can do our driving in the EV. If they mess up power supply we can do our driving in the ICE pickup. Currently gas prices are too darn high so we do most of our driving in the EV (26K miles per year).
We have further energy security by having lots of solar. I simply can’t drill and refine oil on my own to fuel my ICE pickup. But I supply 82% of the power we need through solar, including charging the EV for about 22K to 23K miles per year that are charged at home.
It’s wonderful that you can self sustain your home and your EV. It’s also nice that you can afford to install solar, buy an EV and an ICE vehicle and I assume install a charging station? Most folks can’t. People would have to go into huge indebtedness to do all that. How about those that live in the country? Also how about an EV in say a hurricane? We were without power for a week after Hurricane Idalia. The nearest charging station to us is like 25 miles away. Wouldn’t do us any good unless we wanted to use the power of the EV battery to keep running to the charging station. Not feasible. If folks in a city want their EVs...they should go for it. If someone doesn’t, especially in the rural areas, they should have to or be forced to.
