Kind Code:
A1
Abstract:
The present application discloses a box body of a battery, the battery, and an electrical device. The box body comprises: a thermal management component for containing a fluid to adjust the temperature of battery cells, a protective member for protecting the thermal management component, and a heat absorption member. The heat absorption member is disposed between the thermal management component and the protective member, and the heat absorption member is configured to absorb, when the temperature of the thermal management component reaches a threshold, heat generated by the thermal management component. In the box body of embodiments of the present application, the heat absorption member is disposed between the thermal management component and the protective member, so that heat generated on the thermal management component can be absorbed by the heat absorption member and then transmitted to the protective member, thereby reducing, taken as a whole, heat transmitted to the protective member, and effectively solving the problem of abnormal noise caused by uniform temperature on the protective member.
