Storage battery, storage-battery evaluating device, and storage-battery evaluating method

摘要

A storage battery includes power storage devices in series and switching circuits each arranged between adjacent power storage devices. Each switching circuit includes an input terminal I, an output terminal O, an input terminal Si, and an output terminal So, a first switch that electrically connects the input terminal Si and the output terminal O, a second switch that electrically connects the input terminal I and the output terminal So, a third switch that electrically connects the input terminal I and the output terminal O, and a fourth switch that electrically connects the input terminal Si and the output terminal So. The input terminal Si is electrically connected to the output terminal So of one of adjacent switching circuits and the output terminal So is electrically connected to the input terminal Si of the other of the adjacent switching circuits.
