BATTERY MODULE, BATTERY PACK AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/168553
Kind Code:
A1
Abstract:
The present application provides a battery module, a battery pack, and an electric device. The battery module of the present application comprises: first battery cells and second battery cells, the number a of first battery cells being greater than or equal to the number b of second battery cells. It is assumed that the product of volume energy density E1 and thickness T1 of the first battery cells is X1, the product of volume energy density E2 and thickness T2 of the second battery cells is X2, and X1/X2 satisfies: .35≤X1/X2≤18. Therefore, the uniformity of energy density distribution and the overall volume energy density of all battery cells are improved.
