Abstract

The disclosure relates to a battery pack. The battery pack comprises: a casing; a cover, which is disposed to cover the casing; a battery assembly, which is disposed within an enclosed space formed by the casing and the cover; and an end assembly, which includes a panel and two or more connectors fixed to the panel. The battery assembly is electrically connected to a device outside the enclosed space by the connectors. The panel is sealedly connected to the casing or the cover, and is fixedly connected to the casing by a bracket. In the battery pack according to the embodiment of the disclosure, the end assembly integrated with two or more connectors is fixed to the casing by the bracket, thus the weight of the connectors is borne by the bracket and the connectors are not easy to be detached.

First claim
