This paper started with a very good article in one of my favorite sources (Science), about how consumers are likely to demand EV batteries in the near-term future that can fast-charge at record rates. And further, if manufacturers could not supply these, this would put California’s goal of mandating that all light vehicles be mostly electric starting in 2035 at risk.
Contrary to the above argument is the fact that most EV owners in my home state (California) charge in the evenings at home. Experts noted most EV charging is done in off-peak hours, mostly because of time-of-use rates set by utilities that push drivers to power up overnight. Industry experts said efficient charging technology is just getting started.
To reinforce this fact, my electric utility (PG&E) and, I assume, other investor-owned utilities in our state, offer special rates for EVs. These rates are three-tiered time-of-use rate, with a very-low off-peak rate (from 11:00 PM until 7:00 AM).
