More Information
Summary:The present invention provides a battery voltage equalizer to equalize the voltages of the series of connected battery strings. The battery voltage equalizer has a plurality of energy transferring circuits having bridge architecture. Each energy transferring circuit having 4 nodes comprises a first semiconductor switch, a first diode, a second semiconductor switch, a second diode, and an inductor. One end of the first semiconductor switch is connected to the negative end of the first diode. One end of the second semiconductor switch is connected to the positive end of the second diode. The inductor crosses between the negative end of the first diode and the positive end of the second diode.
