I'm thinking of building my own dc motor controller and a switched battery charger for my future EV. The charger and motor controller both have
1. a large and expensive capacitor bank in parallell with the batteries
2. a large and expensive heat sink
3. a case
So to "upgrade" a motor controller to a combined charger/motor controller I would only need an inductor, a slightly larger heatsink and case, a MOSFET, a diode, a rectifier and some control electronics.
What do you think?
