Abstract: The present disclosure provides a battery pack including a casing and a battery module housed in the casing. The battery module can include a plurality of batteries arranged along a length direction and an end plate located at an end of the plurality of batteries in the length direction. The end plate can include a main body portion and a lug integrally formed with the main body portion, wherein the lug protrudes outwardly from the main body portion along the length direction and is fixedly connected to the casing. The design disclosed herein reduces the number of the components that are fixedly connected between the end plate and the casing, the number of steps in the operating procedure, and the production cost.

Abstract: The present disclosure provides a battery module including a plurality of batteries arranged sequentially in a length direction and a cushion pad disposed between two adjacent batteries in the length direction. The cushion pad can include a main body portion and an extending portion extending outwardly from an end surface of the main body portion in a height direction. The extending portion can include a pair of convex portions and a concave portion between the pair of convex portions. The design can ensure that the cushion pad does not exceed the corresponding surface of the battery in the height direction when pressed, and thus does not affect the flatness of the corresponding surface of the battery.
