With ever-increasing number of BEVs, I can't help but think we as a group must be putting a significant strain on the grid at the top of the charging hour. For example, I have mine set to charge at 12AM PST. I'd wager that the majority of BEV owners also set to charge at 12AM. Not counting Alaska/Hawaii, there would be 4 different massive surges at midnight for the 4 different time zones in the US.
Instead of setting a scheduled charging time as above, why not have an option that would somewhat randomize when the car starts charging? One way would be to calculate when to charge, so that the car finishes charging 1 hour before departure time. For example, if I have to leave for work at 8AM and I drove 30 miles the day before, the car would stop charging at 7AM, meaning it would start charging at 5:50AM (assuming 27mph charge rate). The start charge time will be "randomized" as a group based on the amount to be charged.
One caveat to the above scheme is for those who work at a later shift. As an example again, let's say I go to work at 9PM and the worst TOU (time-of-use electricity rate) is 4PM-9PM, obviously it would not be beneficial to use my randomized charging scheme, since the charge time would occur during the worst TOU. For those late shift individuals, the current scheduled charging scheme would make more sense.
What do you guys think? Much ado 'bout nuthin'?
