Abstract
The present application belongs to the technical field of batteries. Disclosed are a battery device and an electric device. The battery device comprises a battery cell assembly and a thermal management component, the battery cell assembly comprising a plurality of battery cells arranged in a first direction. The thermal management component is arranged on one side of the battery cell assembly in a second direction, and is configured to adjust the temperature of the battery cells, and the second direction intersects the first direction. The heat exchange efficiency between the thermal management component and the battery cell of the battery cell assembly located at at least one of the two ends of the battery cell assembly in the first direction is less than the heat exchange efficiency between the thermal management component and any battery cell located between the two ends thereof in the first direction. The battery device has high reliability.
