To provide a technology that can appropriately protect a battery even for an external charger having various performances and qualities.SOLUTION: There is provided a battery protection device to be installed in a vehicle. The battery protection device has a relay provided between the battery and a circuit on the vehicle side, and a control device capable of monitoring the battery voltage while the vehicle is parked and executing a protection process to open the relay when the battery voltage or a change thereof indicates a predetermined abnormality. The control device suspends the execution of the protection process when the daily change width of the voltage of the battery is equal to or less than a predetermined first upper limit value.SELECTED DRAWING: Figure 2

    【課題】性能や品質が様々な社外品の充電器に対しても、バッテリを適切に保護することができる技術を提供する。【解決手段】本明細書は車両に搭載されるバッテリの保護装置を開示する。保護装置は、前記バッテリと前記車両側の回路との間に設けられたリレーと、前記車両の駐車中に前記バッテリの電圧を監視し、前記バッテリの電圧又はその変化が所定の異常を示すときに、前記リレーを開放する保護処理を実行可能な制御装置と、前記制御装置は、前記バッテリの電圧の一日当たりの変化幅が、所定の第1上限値以下であるときに、前記保護処理の実行を中断する。【選択図】図2
