    摘要: A fire suppression system for a battery pack includes a controller, an inlet line, an outlet line, a detector, a first pressure vessel with a first valve, and a second pressure vessel with a second valve. The pack includes: an inlet, battery modules housing battery cells, and an outlet. The inlet line connects to the pack inlet and the outlet line connects to the outlet. The detector senses a condition indicative of a fire event caused by a battery cell breaking and produces a signal. The controller, connected to the detector, determines a fire event is occurring based on the signal. The first vessel and the second vessel connect to the inlet line. A first suppressant flows from the first vessel into the pack when the controller opens the first valve. A second suppressant flows from the second vessel into the pack when the controller opens the second valve.

    摘要: A battery includes an explosion-proof valve and a battery casing. The explosion-proof valve is arranged in the battery casing. The explosion-proof valve is arranged on a first surface of the battery casing, the explosion-proof valve includes a fragile portion. The fragile portion protrudes toward a middle region of the first surface. The fragile portion includes a first end point and a second end point, and an area jointly enclosed by a connection line between the first end point and the second end point and the fragile portion between the first end point and the second end point is a. A minimum distance between the first end point and a circumferential edge of the first surface is b. A minimum distance between the second end point and the circumferential edge of the first surface is c.
