I want to put some solar cells on my EV (120V VW) to charge the accessory battery. However, the Acc Batt doesn’t need much charging since I don’t often drive at night, so it’s just running the contactor and blinker/brake lights.
I would like to create a switching charger that will use a bunch of strings of solar cells in parallel to charge the Acc Batt, then when it is full will switch the strings to series and charge the traction pack. Does anyone know if anything similar has been done before?
