What kind of device would i need to control the charge flow between a battery, a load, and a generator. Where the battery powers the load and the generator charges the battery when it discharged. How would i build this control sequence into a small circuit, say with a Raspberry Pi?
Essentially the circuit flow is this: A hydrogen fuel cell powers an electric motor (inductive load) while an on board generator charges up a battery. I need a circuit that allows me to discharge the battery through the motor when the fuel-cell doesn't have access to hydrogen, and switch the the fuel cell if the battery is dead. While the generator charges the fuel-cell fuel source when dead (battery powers motor) then when the battery is dead and fuel cell is charged the process reverses where the battery is charged by the generator and the fuel cell powers the load. What kind of circuit do i need to control this?
