To provide a battery protective device capable of appropriately protecting a battery from collision with a vehicle.SOLUTION: A battery tray 12 mounted with a battery 10 is supported by a variable structure 21 and a variable structure 22 on both lower sides in the vehicle width direction of a vehicle 1. The variable structure 21 and the variable structure 22 are supplied with gas of an inflator 30 so as to rapidly expand and change shape. When predicting collision, an ECU 100 causes the inflator 30 to actuate and supplies the gas of the inflator 30 to the variable structure 21, the variable structure 22 or both of the variable structures in accordance with a predicted collision situation. Due to this configuration, in accordance with the predicted collision situation, the shapes of the variable structures 21, 22 are rapidly changed and the battery 10 is moved vertically so as to appropriately protect the battery 10 from the collision with the vehicle 1.SELECTED DRAWING: Figure 2

    【課題】車両に対する衝突からバッテリを適切に保護することができるバッテリ保護装置を提供する。【解決手段】バッテリ10が搭載されたバッテリトレイ12を、車両1の車幅方向両端側の下部において、可変構造物21と可変構造物22とで支える。また、可変構造物21および可変構造物22は、インフレータ30のガスが供給されることにより、急速膨張し、形状を変形させる。ECU100は、衝突を予測すると、インフレータ30を作動させるとともに、予測した衝突状況に応じて、可変構造物21または可変構造物22、あるいは双方にインフレータ30のガスを供給させる。これにより、予測した衝突状況に応じて、可変構造物21,22の形状を急速変化させ、バッテリ10を上下方向に移動させ、車両1に対する衝突からバッテリ10を適切に保護する。【選択図】図2
