Title:
BATTERY AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/124705
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a battery and an electrical apparatus. The battery comprises a battery cell group and a thermal management apparatus, the battery cell group comprising a plurality of battery cells, the thermal management apparatus being used for regulating the temperature of the battery cell group, and at least two surfaces of each battery cell being in heat conduction connection with the thermal management apparatus. The embodiments of the present application can increase the heat exchange areas of battery cells, such that the thermal management apparatus achieves higher efficiency of thermal management on battery cells, thus meeting battery cooling requirements in working conditions of larger currents or more rapid charging, and meeting battery heating requirements in environments having lower temperatures, thereby improving the safety and prolonging the service life of the batteries.
