Abstract
The application provides a battery pack and an electric device, and relates to the technical field of battery packs. The battery pack comprises a shell, a plurality of battery monomers and a cover plate. The shell defines a containing cavity with an opening at the top. The plurality of battery monomers are divided into a plurality of battery groups arranged along a first direction, and each battery group comprises a plurality of battery monomers arranged along a second direction. The cover plate is arranged at the opening and covers the plurality of battery monomers. The cover plate is provided with a plurality of first glue injection areas extending along the second direction. A plurality of first glue injection holes are arranged on the glue injection areas. The first glue injection areas are opposite to the gaps between the adjacent two battery groups and cover the respective partial areas of the adjacent two battery groups. The first direction is perpendicular to the second direction. The battery pack provided by the application is beneficial to reducing the structural members in the battery pack, simplifying the fixing steps of the battery monomers, and improving the assembly efficiency of the battery pack.
