A MULTI-BATTERY SYSTEM FOR HIGH VOLTAGE APPLICATIONS WITH PROPORTION POWER SHARING

摘要

A multi-battery system for high-voltage applications with proportional power sharing comprises a circuit having a circuit positive 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, energy storage means, system output voltage sensing means and a logic gate. Protection means generates a protection signal and the voltage sensing means 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 means 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".
