PROBLEM TO BE SOLVED: To estimate temperature of a power storage system when an ignition switch is an off-state.SOLUTION: A power storage system to be mounted on a vehicle comprises: a temperature sensor for detecting temperature of a power storage device; and a controller for estimating standing temperature of the power storage device when an ignition switch of the vehicle is an off-state. The controller detects temperature of the power storage device when the ignition switch is turned on by using the temperature sensor, every time the ignition switch is turned on. Then, the controller estimates the standing temperature, by using an average value of at least two temperature values among plural temperature values when the ignition switch is turned on which are detected in a predetermined period.

    【課題】イグニッションスイッチがオフであるときの蓄電装置の温度を推定する。【解決手段】車両に搭載される蓄電システムは、蓄電装置の温度を検出する温度センサと。車両のイグニッションスイッチがオフであるときの蓄電装置の放置温度を推定するコントローラと、を有する。コントローラは、イグニッションスイッチがオンされる度に、イグニッションスイッチがオンされた際の蓄電装置の温度を、温度センサを用いて検出する。そして、所定期間中に検出されるイグニッションスイッチがオンされた際の複数の各温度のうち、少なくとも2つ以上の温度の平均値を用いて、放置温度を推定する。【選択図】図3
