Title:
BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/134536
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a battery (100) and an electric device. The battery (100) comprises a housing (10), a heat exchange module (20), and a battery cell module (30). The housing (10) is provided with an accommodating cavity (11). The heat exchange module (20) comprises a first heat exchange assembly (21), and the first heat exchange assembly (21) is provided in the accommodating cavity (11). The battery cell module (30) is provided in the accommodating cavity (11), the battery cell module (30) comprises several battery cells (31), the battery cells (31) abut against the first heat exchange assembly (21), and the first heat exchange assembly (21) is provided perpendicular to a direction (X) where the battery cells (31) are stacked. By means of the structure, each battery cell (31) can exchange heat with the first heat exchange assembly (21), so that the temperature of each battery cell (31) in the battery (100) is equal, thereby preventing the output power of the battery (100) from being reduced due to the non-uniform temperature inside the battery (100).
