Traction battery pack thermal management system and thermal management method

The invention provides a traction battery pack thermal management system and a thermal management method. A thermal management system for a traction battery pack includes: at least one cell stack having a plurality of battery cells; a heat exchange device having a first plate, a second plate, and at least one coolant channel that conveys coolant between the first plate and the second plate. The first plate is a first material. The second plate is a second material that is different from the first material. The thermal management system also includes at least one thermal circuit breaker in the heat exchange device. The at least one thermal circuit breaker is configured to suppress thermal energy transfer from a first region of the heat exchange device to a different second region of the heat exchange device. 本公开提供了"牵引电池包热管理系统和热管理方法"。一种用于牵引电池包的热管理系统包括：至少一个电芯堆，所述至少一个电芯堆具有多个电池电芯；热交换装置，所述热交换装置具有第一板、第二板和至少一个冷却剂通道，所述至少一个冷却剂通道在所述第一板与所述第二板之间传送冷却剂。所述第一板是第一材料。所述第二板是与所述第一材料不同的第二材料。所述热管理系统还包括所述热交换装置中的至少一个热断路器。所述至少一个热断路器被配
