    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.
