Clarifications

In previous posts I mentioned the number of EV charging stations in the US as well as the effect of a net metered solar array in literally creating a solar power car. Here are some more precise comments.

While the DOE shows 4,364 stations (about to be updated by 10 for Vermont), the Electric Drive Transportation Association (EDTA) states there are 10,000. Here’s the difference. The DOE stations are physical sites listed while the EDTA number is the number of connections possible. So at one station there may be multiple plugs. While we don’t mention for gas stations how many pumps they have the difference with plugs in the amount of time one would spend connected thus making the number of plugs equally important as the number of locations.

Vermont has public charging at 15 distinct locations – 14 Level 1 and 15 Level 2 plugs, as well as a number of non-official level 1 plugs available.

Regarding a solar powered car, I had assumed that all the power my solar panels were generating were going directly back to the grid. I learned that in fact the electrons are first used to offset any load being generated at home and then only the excess goes to the grid. So, as long as I’m charging my car while the sun is shinning I am running on solar power.
