  • Patent number: 11641037
    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.
