US Patent 12136721 Battery busbar temperature management system

A battery system includes a fluid tube that cools busbars of a battery module having one or more cells. The fluid tube is constructed of an electrically insulative/thermally conductive material. Thus, the fluid tube can be affixed directly onto the surface of the busbar. The fluid tube can be used with chilled water to reduce the temperature of the busbars and hot water to increase the temperature of the busbars. The fluid tube can be affixed to the busbars using a flexible joint material that allows for the expansion and contraction of the busbars. The flexible joint material an electrically insulative/thermally conductive material. The joint material can include a resin and conductive powder.
