The invention provides a battery pack cooling liquid leakage detection system. The system comprises a low-voltage wire harness, a plurality of probes and a battery management system; the low-voltage wire harnessis arranged along the inner periphery of a battery pack, forms a loop in the system and extends into the battery pack to form a plurality of branches; the plurality of probes are respectively arranged at the tail ends of the plurality of branches and are used for detecting the leakage of the cooling liquid; and the battery management system is used for executing corresponding actions according to the detection results of the probes and informing a user of the detection results. According to the battery pack cooling liquid leakage detection system, the leakage condition of the cooling liquid in the battery pack can be detected, a user can know the leakage position and the leakage degree of the cooling liquid; and in addition, the system is simple in structure, only the low-voltage wiring harness needs to be improved, and therefore, the cost can be saved. Compared with an existing water sensor, the system has higher detection sensitivity and durability.

    本发明提供了一种电池包冷却液泄漏检测系统,包括:低压线束,沿着电池包的内周围设置,在系统形成回路,并且向电池包的内部延伸形成多个分支;多个探头,分别设置于多个分支的末端,用于检测冷却液的泄漏;以及电池管理系统,根据探头的检测结果执行所对应的行动,并通知用户检测结果。根据本发明的电池包冷却液泄漏检测系统可以检测到发生在电池包内部的冷却液的泄漏情况,并且还可以使用户了解到冷却液的泄漏位置及泄漏程度,此外,该系统结构简单,仅需改良低压线束,不仅可节约成本,并且相比现有的水传感器具有更高的检测灵敏度及耐久性。
