Provided are a terminal protection device and a battery module. The terminal protection device includes a base having a bottom portion and side plates connected to peripheral sides of the bottom portion, the side plates and the bottom portion together form an accommodation cavity, and an input port is in communication with the accommodation cavity; each of the side plates is provided with an input port, through which an output electrode passes; each of the side plates is further provided with a connection port, the connection port is in communication with the accommodation cavity such that an external electric connector can pass through the connection port) and be connected to the output electrode; and a protection plate is provided at the connection port, and the protection plate detachably covers the connection port.

Terminal protection device and battery module

This application provides a battery module and an assembly method for a battery module. The battery module includes batteries and a framework assembly. The framework assembly includes a first partition, two second partitions, and a securing clip. The first partition extends in a second direction. Each second partition extends in a first direction, and the two second partitions are located respectively on two sides of the first partition and form a cross-shaped structure together with the first partition. The securing clip fits with the two second partitions and secures the two second partitions to the first partition. The batteries are disposed on two sides of each second partition of the framework assembly in the second direction. The two second partitions of the framework assembly are secured to the first partition by using the securing clip, thereby improving the strength of connection between the second partitions and the first partition.

The present application provides an explosion-proof valve, a battery pack, and an electric vehicle. The explosion-proof valve includes a first connection member, a second connection member, a resilient connection member, and an explosion-proof film. An upper port is formed on the first connection member that includes an ejector pin. The second connection member is disposed at an interval from the first connection member. The first and second connection members are tightly in a sealed connection with the resilient connection member. The explosion-proof film is disposed at the upper port and seals the upper port, and the explosion-proof film is located above the ejector pin. Because the explosion-proof valve is directly disposed on a base plate of a case in a vehicle body using the first and second connection members, the explosion-proof valve can fully use narrow space between the base plate of the battery pack and the vehicle body.

Explosion-proof valve, battery pack, and electric vehicle

The present application relates to a battery module. A battery module includes a base, end plates, side plates and a plurality of sleeve members, wherein the end plates and the side plates are connected to the base through the sleeve members, and each sleeve member includes a pipe body and a connecting piece. The battery module further includes a transition piece having a transition plane perpendicular to the axis of the pipe body. The connecting piece has a mating surface toward the transition piece, and the mating surface clings to the transition plane. This solution enables the connecting piece to be screwed into the base along the axis of the pipe body, reducing the difficulty of connecting the connecting piece to the base, and improving the installation efficiency.
