Title:
VOLTAGE EQUALIZATION CIRCUIT SYSTEM
Document Type and Number:
Japanese Patent JP2017028864
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an equalization circuit system that simplifies a system configuration by reducing the total number of switches.SOLUTION: A power storage cell voltage equalization circuit is made to operate by using, an input voltage, a rectangular wave voltage occurring at a switching node in a power storage module voltage equalization circuit, whereby the power storage cell voltage equalization circuit is made switchless. A resonance type voltage doubler rectification circuit can be used as a typical power storage cell voltage equalization circuit. A switched capacitor, the resonance type voltage doubler rectification circuit, a step-up/step-down converter or the like can be used as the power storage module voltage equalization circuit.SELECTED DRAWING: Figure 33
