Abstract
A power storage device includes: a plurality of series-connected battery cells (311); a balance circuit (112) that is provided for each of the plurality of battery cells (311), and is connected with corresponding one of the battery cells; a first temperature sensor (111) that is provided for every one or more of the balance circuits (112), and measures a temperature of a corresponding balance circuit (112); and a control unit (121) that stops an operation of the corresponding balance circuit (112) when a first measured temperature measured by the first temperature sensor (111) is equal to or more than a first upper reference temperature, and restarts an operation of the corresponding balance circuit (112) when the first measured temperature becomes equal to or less than a first lower reference temperature that is lower than the first upper reference temperature after an operation of the corresponding balance circuit (112) is stopped.
