Abstract
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.
