Battery thermal management system for hybrid and all-electric vehicles using a heating condenser

摘要

A battery thermal management system comprising a battery pack, a heat exchanger in fluid communication with the battery pack, a pump interposed between the heat exchanger and the battery pack for flowing a heat exchange fluid in a refrigeration cycle between a heat exchanger and the battery pack, includes. A heating condenser is arranged upstream of the heat exchanger with respect to the flow direction of the heat exchange fluid in the cooling circuit downstream of the battery pack and with respect to the flow direction of the heat exchange fluid in the cooling circuit. A valve is arranged in the cooling circuit with respect to the flow direction of the heat exchange fluid in the cooling circuit upstream of the heating condenser. The valve controls at least a portion of the flow of the heat exchange fluid through the heating condenser and / or the heat exchanger.
