The present invention 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 in sealed connection with the resilient connection member. The explosion-proof film is disposed at 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 using the first connection member, and directly disposed in a vehicle body using the second connection member, the explosion-proof valve can fully use narrow space between the base plate of the battery pack and the vehicle body. Therefore, space utilization of the battery pack in the vehicle body is improved. In addition, because the explosion-proof valve is directly connected to outside of the vehicle body, no additional exhaust pipe structure needs to be provided for the battery pack. Therefore, not only a structure of the battery pack is simplified, but also a total size of the battery pack is reduced, and further, energy density of the battery pack is increased.
