組電池
Document Type and Number:
Japanese Patent JP7103043
Kind Code:
B2
Abstract:
To provide a battery pack that can suppress problems caused by liquid adhering between cells through which a heat medium flows.SOLUTION: A battery pack includes a plurality of battery cells 2, a heat medium passage member through which a heat medium flowing through an internal passage and the battery cells 2 exchange heat, and a plurality of grooves 44 provided in an inter-cell portion 40 to allow the liquid attached to the inter-cell portion 40 to flow downward. The heat medium passage member includes the inter-cell portion 40 in which the heat medium that is interposed between the battery cells 2 adjacent to each other in the stacking direction and flows through the internal passage and the battery cells 2 exchange heat with each other, and a connecting portion 41 that connects the inter-cell portions 40 that are adjacent in the stacking direction and by which the heat medium flows through the internal passage.SELECTED DRAWING: Figure 2
