The disclosure provides a bi-directional switchable cooling flow for traction battery. An apparatus and method, according to an exemplary aspect of the present disclosure includes, among other things, a battery pack having a coolant inlet and a coolant outlet, a coolant source to cool the battery pack, and a proportional valve in communication with the coolant inlet and the coolant outlet, and in communication with the coolant source. A battery control module controls the proportional valve such that a direction of flow is switchable at the coolant inlet and the coolant outlet based on temperatures at the coolant inlet and the coolant outlet to provide bi-directional cooling flow through the battery pack. The battery control module directly connects the coolant outlet to the coolant inlet via the proportional valve to bypass the coolant source in response to a predetermined condition.

    本公开提供“用于牵引电池的双向可切换冷却流”。根据本公开的示例性方面的设备和方法尤其包括:电池组,所述电池组具有冷却剂入口和冷却剂出口;冷却剂源,所述冷却剂源冷却所述电池组;以及比例阀,所述比例阀与所述冷却剂入口和所述冷却剂出口连通,并且与所述冷却剂源连通。电池控制模块控制所述比例阀,使得流动方向可基于所述冷却剂入口和所述冷却剂出口处的温度而在所述冷却剂入口和所述冷却剂出口处切换,以提供通过所述电池组的双向冷却流。所述电池控制模块响应于预定状况而经由所述比例阀将所述冷却剂出口直接连接到所述冷却剂入口以绕过所述冷却剂源。
