|1. (WO2017064907) BATTERY PACK|
|Applicants:||KABUSHIKI KAISHA TOYOTA JIDOSHOKKI
In this battery pack 1, battery modules 3 inside housing spaces S are held together by a main body part 4 and a lid part 5 in a state in which one group of facing portions 42 from heat transfer plates 15 abuts heat transfer members 43 respectively provided on one side surface 7a and another side surface 7b of a standing portion 7 in the main body part 4, and another group of facing portions 42 from the heat transfer plates 15 abuts heat transfer members 43 respectively provided on side surfaces 8a, 9a from the lid part 5. By holding together the battery module 3 in this manner with the main body part 4 and the lid part 5, the occurrence of warping in the battery modules 3 due to a reactive force from the heat transfer members 43 is suppressed, thereby allowing the heat transfer plates 15 to abut the heat transfer members 43 firmly. Consequently, the efficiency of heat transfer mediated by the heat transfer plates 15 can be improved.
