Abstract: Provided a battery and an electric apparatus. The battery includes a box, a battery unit, and a protective member. The box includes a first wall. The battery unit is accommodated within the box, where the battery unit is provided with a pressure relief mechanism, and the pressure relief mechanism is configured to form a pressure relief hole for releasing substances inside the battery unit. The protective member is accommodated within the box, where at least a portion of the protective member is located between the first wall and the pressure relief mechanism and configured to cover the pressure relief hole in an axial direction of the pressure relief hole. battery unitIn the embodiments of this application, redundancy designed for the dimension of the protective member can be reduced while thermal protection requirements are met, thereby reducing energy density loss of the battery and improving safety of the battery.

Abstract: The embodiments of the present application provide a method, apparatus and system for thermal runaway processing and a storage medium. The method first obtains a battery parameter for each of a plurality of battery modules in a power battery pack, then determines that a thermal runaway is occurred in a first battery module based on the battery parameter for each of the plurality of battery modules; and then obtains a second battery module based on the first battery module, wherein the second battery module corresponds to at least one battery module excluding the first battery module in the power battery pack; and finally supplies power to a chiller system with the second battery module.

Abstract: A thermal runaway trigger method relates to the technical field of batteries. The thermal runaway trigger method includes: providing a battery cell and a heating member arranged in the battery cell; and heating the inside of the battery cell by the heating member, so as to cause a thermal runaway of the battery cell. The heating member is arranged inside the battery cell, and the heating member heats the inside of the battery cell to cause the thermal runaway of the battery cell, so that the inside of the battery cell can be heated to cause the thermal runaway of the battery cell in a relatively short time. Due to the reduced internal space of the battery cell, the range of diffusion of the heating member inside the battery cell is small, and the heat loss of the heating member is relatively small.
