Title:
電池パック
Document Type and Number:
Japanese Patent JP5753910
Kind Code:
B2
Abstract:
Technical Problem Improve heat-radiating characteristics while resolving the drawbacks associated with use of a metal outer case. Solution to the Problem The battery pack is provided with a plurality of battery cells 1, a battery holder 2 that retains the plurality of battery cells 1, and a plastic resin outer case 4 that houses the battery holder 2. Metal heat-radiating plates 14 are insertion-molded into the outer case 4; parts of the heat-radiating plates 14 are exposed from inside and outside surfaces of the outer case 4; and the battery holder 2 is thermally coupled with the heat-radiating plates 14 exposed on the inside surfaces of the outer case 4. By putting the battery holder 2 in contact with the outer case 4 in a thermally coupled manner, the externally exposed heat-radiating plates 14 serve as heat-sinks, and heat generated by the battery cells 1 is efficiently dissipated outside the battery pack through the battery holder 2 to achieve high reliability battery pack operation.
