Provided is a battery assembly, comprising an upper cover, a lower cover and a battery, wherein the upper cover is sealed together with the lower cover to form a vacuum sealed cavity, and the battery is provided inside the sealed cavity; a heat conducting element is provided inside the sealed cavity for performing heat exchange with the outside of the sealed cavity; a limiting device is provided inside the sealed cavity for limiting the location of the heat conducting element, wherein when the limiting device is in a heat conducting state, the heat conducting element is located at a location where heat exchange is performed with the outside of the sealed cavity, and when the limiting device is in a non-heat-conducting state, the heat conducting element is located at a location where heat exchange cannot be performed with the outside of the sealed cavity; and a temperature control device is provided inside the sealed cavity for controlling the limiting device so that it can be switched between two states, namely, heat conducting and non-heat-conducting states, according to the change in environment temperature, wherein the heat conducting element, and contact parts of the upper cover/lower cover and the heat conducting element are made of a heat conducting material. |
