Abstract
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.
