Abstract
An input and output device of an inspection device is configured to instruct charging devices capable of charging respective cells to perform constant current charging or constant voltage charging, and acquire a voltage value and a current value of each of the cells from corresponding one of the charging devices. A controller of the inspection device is configured to instruct the charging devices to perform constant current charging of the respective cells, and perform constant voltage charging of the respective cells when a voltage value of each of the cells acquired from corresponding one of the charging devices reaches a preset value. The controller of the inspection device is configured to determine presence or absence of a micro-short circuit in each of the cells with reference to a peak current value of corresponding one of the cells generated in switching from the constant current charging to the constant voltage charging.
