    摘要: It is an object to provide a circuit for equalizing voltages of energy storage cells, with less number of element and simpler circuit configuration than ever before.A plurality of field-effect transistors are arranged such that each of a plurality of parallel circuits formed, in one of connection states attained by switching of the switches, by connecting in parallel energy storage cells to perform mutual charging and discharging, includes a field-effect transistor adapted to avoid blocking a current having one of opposite polarities in the each of the plurality of parallel circuits, and a field-effect transistor adapted to avoid blocking a current having the other polarity in the each of the plurality of parallel circuits. This makes it possible to perform a voltage equalization operation using a small number of transistors.

    摘要: An electric energy storage system is designed to equally utilize electric energy storage banks during charging/discharging, and keep fluctuation of an input voltage from a charger or an output voltage to a load, within an arbitrary range, while equally utilizing the electric energy storage banks during charging/discharging. The electric energy storage system comprises an electric energy storage module, a charger, a balancing circuit, a voltage detection section, taps led out, respectively, from one of opposite terminals of the electric energy storage module and/or the other terminal of the electric energy storage module and/or one or more of series-connection points between the electric energy storage units, through respective switches, and a switch control section for switching the switches such that one of the taps is connected to one of opposite terminals of the charger. The switch control section is operable to sequentially switch the switches according to progress of the charging.
