Assignee: VOLVO CAR CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A battery module comprising:
a plurality of sides defining a housing of the battery module;
a plurality of battery cells held within the housing of the battery module;
a plurality of heat pipes configured to be thermally connected to a heat reservoir, the heat pipes being individually sealed and integrated in an external surface of one side of the housing of the battery module to internally re-distribute heat within the battery module, the heat pipes being soldered onto the external surface of the battery module and configured to be arranged in physical contact with a heat conducting element for transferring heat to and/or from the battery module, each heat pipe in the plurality of heat pipes comprising a condensation portion positioned along a centrally arranged portion of the external surface of the battery module and an evaporation portion positioned relatively closer to a periphery of the external surface of the battery module as compared to the condensation portion; and
the heat conducting element centrally arranged along a longitudinal axis of the battery module,
wherein the heat pipes soldered onto the external surface of the battery module are configured to transport heat away from the periphery of the external surface of the battery module to the centrally arranged portion of the external surface, via the heat pipe, to internally re-distribute heat within the battery module separate from heat being transferred from the battery module to the heat reservoir, the heat conducting element, an external heat sink, and/or an external cooling plate.
