To provide a secondary user with history information on a battery required for secondary use of a battery device after ensuring security.SOLUTION: A battery device 40 comprises: a power storage unit 420; a signal input/output unit 430 to which security signals are input; a storage unit 450 for storing information indicating a state of the power storage unit 420; and a changeover unit 440 that according to a signal input to the signal input/output unit 430, validates or invalidates reading of the information in the storage unit 450 from the outside. When a release signal, one of the security signals, is input to the signal input/output unit 430, the changeover unit 440 validates reading of the information in the storage unit 450 from the outside.SELECTED DRAWING: Figure 2 【課題】バッテリ装置が二次利用される際に必要なバッテリの履歴情報について、セキュリティを確保した上で二次利用者に応じて提供する。【解決手段】バッテリ装置４０は、蓄電部４２０と、セキュリティ信号が入力される信号入出力部４３０と、前記蓄電部４２０の状態を示す情報を記憶する記憶部４５０と、前記信号入出力部４３０に入力された信号に応じて、前記記憶部４５０の情報の外部からの読み出しを有効または無効にする切り換え部４４０と、を備え、前記信号入出力部４３０に、前記セキュリティ信号の一つである解除信号が入力された場合、前記切り換え部４４０は前記記憶部４５０の情報の外部からの読み出しを有効にする。【選択図】図２
