#3We were thinking to add PV to the roof of the office for daytime charging of employee cars. The cheapest power, and the right time to use it

#4The more detailed Nature article that this report is based on is open access (no paywall) and readable here:
"Charging infrastructure access and operation to reduce the grid impacts of deep electric vehicle adoption"

The suggestion to use more daytime charging is specific to California, since California's future energy trajectory is weighted toward more solar. A state like Texas which has more renewable energy output at night, from wind [1], wouldn't necessarily need more daytime charging. If California ends up installing more offshore wind than currently projected, that could also change the optimal charging strategy.

Did anyone imagine that by 2030 California would have most of its power storage in cars? So all the people on here that want to get rid of cars should chuck their air conditioners and heaters right now.

#6We have the means to balance grid usage by telling specific families at which time they should charge their vehicles.

#7"time of use" tariffs will be important to keep things balanced. People who want to minimize their power bill should have the option to pick the "time of use" pricing and shift some of their consumption off-peak. Others can choose to pay more for the convenience of not having to worry about all that stuff. How much more, that can be determined by market forces.

I'd say that plugging in a car should mean - charge it enough to get me to a hospital. Beyond that wait for the optimum charge time. However there should also be a screen that overrides this if you are going on a trip or something.

#9The solution to this is going to be have customers enroll in smart charging. Keep your car connected to the smart charger when not in use and during times of excess power charge the car for a few cents per kw.

Then everyone‘s charger decides „now is the time“ and the grid gets overloaded
