It's really great to learn that this is something that is possible, to control the charge rate from the charger itself, opens lot of doors for renewable energy use like in this case with the solar. I plan to build an off grid homestead and was kind of wondering if it's possible to control how much power the car draws, and the fact that it's a simple PWM signal makes it very simple if I wanted to design my own charger even. I suppose this works with level 1 charging to with 120v right? Can you get it down to like say, 100w if you really wanted to, or is there a hard minimum? Maybe not with that particular charger, but like with the standard in general?
I don't have an EV yet myself but that will probably be my next major purchase. I just need to pay off my land first... and then save up. Hopefully the prices come down in the next couple years. I really want a truck, but I will settle for a SUV if it can tow a small trailer.
