Quoted from zaphX:Are you going to acknowledge that the reason for it is to give EV charging customers even better rates?
"Separately metering EV charging independently from a customer’s main utility meter is crucial because special rate structures apply to EVs that allow customers to buy less costly power during off-peak times."
I don't get this part. Why is a separate meter needed? As I posted previously, our local power company already offers a special rate for EV owners which applies in the off-peak times. No separate meter needed. I guess you have to prove to them somehow that you do have an EV. However, that TOU (Time of Use) plan isn't all roses, as you specifically have to pay a higher rate than everyone else for the critical 4-9 PM hours. So unless you can cut back your usage during that time, you have to factor that in. This is where having solar could be a benefit. Some of my neighbors say their electrical bill is basically zero with their solar panel installation, even if they crank the AC down low during the summer month 4-9 PM window. So if you have that and you toss in EV charging, you should come out ahead with the EV TOU plan.
However, I will say we have been on smart meters for some years now, so that could be the issue. If you don't have a smart meter then I don't think there would be a way to know what electricity you are using during all times of the day. Then, you would need a separate meter. I don't know to what degree smart meters have been implemented within the USA or elsewhere globally.
The smart meter thing is kind of cool, I can log in and track my kWh usage by the hour for any day.
