A thermal management system (270) for a rechargeable secondary battery has an electrically insulating material (262) lined inside a metal housing (260). One or more battery packs (24) made of individual cells (12) arranged within the end frame (220) are arranged in the metal housing (260). The thermally conductive particulate filler (264) occupies a gap (264A) between the individual cells (12) and a space between the battery pack and the electrically insulating material gasket (262). The thermally conductive filler (264) reduces thermal impedance from the battery pack (24) to the outer surface of the metal housing (260) to reduce battery pack temperature and extend battery life. 一种用于可充电二次电池的热管理系统(270)，其具有衬在金属壳体(260)内部的电绝缘材料(262)。由布置在端架(220)内的单独的电池(12)制成的一个或多个电池组(24)布置在金属壳体(260)中。导热颗粒填料(264)占据单独的电池(12)之间的间隙(264A)以及电池组和电绝缘材料衬垫(262)之间的空间。导热填料(264)降低从电池组(24)到金属壳体(260)外表面的热阻抗，以降低电池组温度并延长电池寿命。
