| description | 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. |
