The present disclosure provides traction battery thermal management. A vehicle includes a traction battery having a plurality of battery cells arranged in an array and grouped into a plurality of cooling zones. The thermal management system includes a plurality of different loops, each associated with one of the zones. The thermal management system is configured to provide separate heating or cooling to each of the loops to independently control the temperature of the zones. The controller is programmed to, in response to one of the zones exceeding a first threshold temperature and another of the zones being less than a second threshold temperature: command the thermal management system to provide cooling to the loop associated with the one of the zones; and commanding the thermal management system to provide heating to the loop associated with the other one of the zones.

    本公开提供“牵引电池热管理”。一种车辆包括牵引电池,所述牵引电池具有多个电池单元,所述多个电池单元以阵列布置并且分组为多个冷却区。热管理系统包括多个不同回路,所述多个不同回路各自与所述区中的一个相关联。所述热管理系统被配置为向所述回路中的每一个提供单独的加热或冷却以独立地控制所述区的温度。控制器被编程为响应于所述区中的一个超过第一阈值温度并且所述区中的另一个小于第二阈值温度:命令所述热管理系统向与所述区中的所述一个相关联的所述回路提供冷却;以及命令所述热管理系统向与所述区中的所述另一个相关联的所述回路提供加热。
