> Electric cars are primarily charged at off-peak times
When would that time be? I get home from work after 17:00/5:00PM. Plug in my EV, and set the air conditioner to a few degrees lower. I get up and leave for work at 7:00. EV cars with Level 2 charging take from 5h (Mini SE Hardtop) to 12h (Tesla Model S). The average is 8.6h, and median at 8h. [0,1] At Level 1 charging, the charging time can take days, depending on the vehicle.
> According to California Public Utilities Commission (CPUC), the California Energy Commission (CEC) and California Independent System Operator (CAISO), the state’s electricity grid reaches its peak level of usage between the late afternoon and early evening – a time frame in which electricity produced by renewable resources is less available and thus costs more to produce. The peak demand period is generally defined as the hours between 4 to 9PM ... [1]
With the above details, with the best case scenario on timing & charging, that means I must not plug in my vehicle before 9:00PM, but have to before 10:30PM.
If California is hoping that people will plug in their vehicles "at the right time", that is not a re-assuring strategy.

- plorkyeran 4y agoYou plug in your car when you get home, and it starts charging a few hours later at the scheduled time. This is not a remotely complicated problem and it's been solved for years.
