BATTERY MODULE

The present invention provides a battery module, which includes: a plurality of batteries, each battery including a top cover, and a first electrode terminal, a second electrode terminal and an explosion-proof valve being disposed on the top cover in a width direction; and a first heat exchange plate including: a first main body portion and a first bending portion bending from an upper side of the first main body portion to the plurality of batteries in the width direction; the first bending portion covers explosion-proof valves of at least some of the batteries in the width direction, a flow channel for flow of a heat exchange medium is disposed in the first bending portion, and the first bending portion is configured to be capable of leaking the heat exchange medium in the flow channel after being melted. When a high-temperature and high-pressure gas generated inside the batteries breaks through the explosion-proof valves to melt the first bending portion, the heat exchange medium flows out. The heat exchange medium lowers the temperature of the high-temperature and high-pressure gas and/or an outflowing doped electrolyte to avoid fire, and the heat exchange medium may further enter insides of the explosion-proof valves to lower the temperature of the batteries. Accordingly, a degree of thermal runaway of the batteries is reduced, so as to buy escape time for a passenger and/or buy time to extinguish the thermal runaway manually.
