Title
(EN) BATTERY MODULE, BATTERY PACK, AND VEHICLE
Abstract
(EN)
The present application relates to a battery module, a battery pack, and a vehicle. The battery module comprises a plurality of battery units and a fire-preventing structure, anti-explosion valves being provided on the battery units. The anti-explosion valves of the plurality of battery units all face towards the fire-preventing structure. The fire-preventing structure comprises a fire-preventing structure body and a first extension part connected to one end of the fire-preventing structure body, and/or the fire-preventing structure comprises a fire-preventing structure body and a second extension part connected to the other end of the fire-preventing structure body. In the present invention, by means of the fire-preventing structure, when thermal runaway occurs in a battery unit, flames and high-temperature particles expelled from the anti-explosion valve are stopped by the fire-preventing structure body and the first extension part and/or the second extension part, preventing the flames and the high-temperature particles from burning adjacent battery units, thus preventing the battery unit in which thermal runaway has occurred from causing thermal runaway to also occur in battery units adjacent to the anti-explosion valve thereof.
