How does charging at home lessen the stress on the power grid? You're still charging. Didn't CA ask folks not to charge their EV's during certain hours/days?
We had a cold snap here a few weeks ago and the power companies were doing rolling black outs to lessen stress on the grid and asking folks not to charge EV's.
I’m not an expert on this stuff but I have heard that grid managers prefer EV’s to charge after midnight and before 5 AM for balancing reasons, although I don’t actually know what that means. I know a BC hydro rep said they prefer night charging but they don’t incentivize it like some power companies. When we were with Southern California Edison it was definitely cheaper after midnight. Most DC fast charging is done during the day because of road trips. Most home charging is done at night because of commuting. We always set our timer for 1 AM. It’s usually done by 2 AM.
Differential rate or differential meters, that is the answer because it forces EVers to charge during off-peak hours. Several states have both, not only for EVs, but for pool heaters, air conditioners and several other types of equipment. EVs ORIGINALLY were designed in Japan to level-load the power consumption by using the ChaDeMo plug. Being a 2-way plug, you could feed power to the grid in peak ours and recharge during the off-peak. It was the largest socially-funded energy storage project ever conceived, and an amazing one at that.
California has diferential rater and shutdown lines with diferential meters in certains cities, so does Nevada. I have my cars programed to start charging ar 12:30AM, and they are done by 5. I have no restrictions in Florida, but at that time my ACs are working less.
