摘要： An equalization circuit system having a system configuration simplified through reduction of the total number of switches is provided. An electricity storage cell voltage equalization circuit is operated with a square wave voltage generated at a switching node in an electricity storage module voltage equalization circuit as an input voltage, thereby achieving an electricity storage cell voltage equalization circuit without a switch. Typically, the electricity storage cell voltage equalization circuit may be a resonance voltage-doubling rectifier circuit, and the electricity storage module voltage equalization circuit may be a switched capacitor, a resonance voltage-doubling rectifier circuit, a buck-boost converter or the like.

摘要： The disclosure describes a charge device capable of charging electricity storage cells while eliminating a voltage variation among the electricity storage cells without a need for at least a circuit section playing a role in voltage equalization among the electricity storage cells to be designed to have a large current capacity, and describes a charge-discharge device constructed by additionally equipping a discharging function with the charge device. Provided are a charge device and a charge-discharge device each of which comprises a convertor, an input circuit, and a multi-stage voltage doubler rectifier circuit. An element in the convertor configured to be applied with a rectangular waveform voltage is connected to the multi-stage voltage doubler rectifier circuit via the input circuit to thereby realize a voltage equalization function, and an output section of the convertor is connected to the multi-stage voltage doubler rectifier circuit to thereby realize a charging-discharging function.
