The invention discloses a battery protection system and method and a vehicle. The system comprises a battery cooling device which is arranged outside a containing cavity where a battery cell is located; the liquid leakage detection device is arranged in the accommodating cavity and is in contact with the wall surface of the accommodating cavity, and an insulating material and a conductive material are arranged on the liquid leakage detection device; and the controller is connected with the battery cooling device and the liquid leakage detection device, and is used for determining the liquid leakage of the accommodating cavity based on the signal of the conductive material, and controlling the flow of the cooling liquid of the battery cooling device to be reduced to a preset flow in response to the liquid leakage of the accommodating cavity. According to the invention, the technical problem of poor protection effect on the battery cell in the accommodating cavity in the prior art is solved.

    本发明公开了一种电池保护系统、方法和车辆。其中,该系统包括:电池冷却装置,部署在电池电芯所处的容纳腔外部;漏液检测装置,部署在所述容纳腔内部,并与所述容纳腔的壁面接触,所述漏液检测装置上部署有绝缘材料和导电材料;控制器,与电池冷却装置和漏液检测装置连接,用于基于导电材料的信号确定容纳腔发生漏液,响应于容纳腔发生漏液,控制电池冷却装置的冷却液的流量降低至预设流量。本发明解决了相关技术中对容纳腔中的电池电芯的保护效果较差的技术问题。
