1. a kind of lithium ion battery balance module, it is characterised in that including at least two basic battery units;

  • Each described basic battery cells in series is used;

    The basic battery unit includes at least two lithium ion batteries connected and balanced with lithium ion battery parallel connectionBattery;

    During charging, basic battery unit each described is charged simultaneously, when close to default maximum voltage value, by describedEqualizing battery latter stage of charging voltage constant characteristic, consumes unnecessary electricity, suppresses the lithium ion battery in latter stage of charging electricityVoltage between the quick upper drop of pressure, each balanced described basic battery unit;

    During electric discharge, the lithium ion battery and the equalizing battery are discharged simultaneously, in close default minimum voltage valueWhen, the lithium ion battery is shunted using the equalizing battery, suppresses the lithium ion battery in electric discharge latter stage electricityPress the voltage between rapid decrease, each balanced described basic battery unit.
