Solar charging a BMW i3 electric car

One feature of the i3 that wasn’t available on my previous Renault ZOE is the ability to change at very low powers. Of course that means charging can be very slow.

The benefit of this option, which may not be obvious, is that it means the current draw is a good match for solar panels. In other words the car can be entirely charged by solar with nothing being drawn from the grid. Free fuel!
