I have a Ford Escape Hybrid. it is a 330v battery with about 1.4kw of capacity. Currently there is no cost effective after market charger. Also my location in NYC does not allow me a "plug in" option. I had an idea on how to access the battery pack to charge it, but I wanted to know if this is a reasonable way to go about it. All the electronics in the car received the energy from 330v batter. There is a converter there to step it down. There is a wire harness on the back of the battery that supplies the electric to the rest of the truck. This is a 12v system. Is it possible to deliver a 12v charge via a solar charger in series to deliver a charge to the battery system? In other words, splice into a single wire, the positive end of the wire would go to the positive end of the charger and negative to negative. Would the additional amperage return to the battery and charge it, or is this a bad idea?
