The invention relates to the field of new energy electric vehicle corollary equipment, in particular to an active control battery protection device and a control method thereof, and the active controlbattery protection device comprises a battery protection shell and a moving assembly slidably arranged at the bottom of the battery protection shell; the battery protection shell comprises a buffer assembly used for buffering a battery, a driving part enabling the battery protection shell to move is arranged in the moving assembly, and the driving part and the buffer assembly are electrically connected with an ECU. A sensor is installed on the inner side of the automobile threshold beam, and the distance D from the sensor to the battery protection shell is determined; the distance D is inputinto the ECU, the ECU judges whether the invasion amount y is larger than D or not when the automobile threshold beam is collided through internal storage data, and if the invasion amount y is largerthan D, the ECU controls the driving part to enable the battery protection shell to move in the direction opposite to the collision direction. Through the device provided by the invention, the batterypack can be protected.
本发明涉及新能源电动汽车配套设备领域,尤其涉及一种主动控制电池保护装置及其控制方法,包括电池保护壳、滑动设置在电池保护壳底部的移动组件;电池保护壳包括用于缓冲电池的缓冲组件,移动组件内设有使电池保护壳移动的驱动部,驱动部、缓冲组件电性连接有ECU。在汽车门槛梁内侧安装传感器,确定传感器至电池保护壳的距离D;将距离D输入至ECU中,ECU通过内部储存数据判定汽车门槛梁受碰撞时的入侵量y是否>D,如果入侵量y>D,ECU控制驱动部使电池保护壳沿碰撞的反方向移动。通过本发明的装置,能对电池包进行保护。
