ABSTRACT:
A multi-battery system comprises a circuit having a circuit positive terminal and a circuit negative terminal. At least two batteries are provided to combine to deliver required system power. The batteries are connected to a protection circuit, an energy storage device, a system output voltage sensor and a logic gate. The protection circuit generates a protection signal and the voltage sensor generates an enabling signal that are fed into the logic gate as true signals to generate a true control signal. The true control signal causes the energy storage device to discharge. The digital enabling signal for each of the circuits is time-shifted by a time “t” so that at any time one of the circuits is discharging and one of the at least two circuits is charging during said time “t”.
