Love this story.
I follow battery technology closely. Here is what is in production now cheaper LFP batteries with really fast charging times. So 250 miles added in 10 minutes no problem. Today a Co Op could buy fast charging you about $700 capital per vehicle supported. 23 high speed chargers could support 14000 EV households. Ok the $700 per customer includes grid batteries so electrical power purchased at the cheapest rate. Now in Ga 2 cents a kWh is really cool. So sell it at 3 cents plus a monthly access fee of say $50.
Why do this? It’s profitable. What about places charging $0.44 per kWh? They are serving corner cases of folks driving long distances so ok charge a bunch. But if you capture 95% of the charging, the price can come down.
Just saying charging will get better. Note L2 where homes support it is still best for convenience and cost.
Last point. LFP batteries from CATL have an expected life of 1,200,000 miles. I would guess EV vendors will offer transferable warranty soon around 250,000 miles and 12 years so the perception of the EV value at resale goes up.
Which is to say yes to your point EVs are good and getting better.
