Problems solved by technology

[0002] In the prior art, battery modules are generally equipped with single battery explosion-proof valves. One way is to set the single battery explosion-proof valves upwards, that is, towards the battery pack upper cover and the passenger compartment; when one or more of the battery modules When the thermal runaway of a single battery occurs, when the explosion-proof valve of the single battery explodes, the flame, high-temperature medium, and high-temperature gas with a certain impact force are sprayed from the explosion-proof valve directly to the protective cover, and the impact of the gas is easy to make the protective cover The cover was punctured, and sprayed directly onto the upper cover of the battery pack and the passenger compartment, igniting the vehicle and endangering the safety of the occupants and items in the passenger compartment

Abstract

The invention provides a fireproof protective cover and a battery module, and relates to the technical field of batteries. The battery module comprises a shell, a single battery and a fireproof protective cover, the single battery and the fireproof protective cover are mounted in the shell, the protective cover body is fixed to the shell, the battery module is provided with a single battery anti-explosion valve, and a flow guide hole corresponds to the single battery anti-explosion valve. The fireproof protective cover comprises a protective cover body and a protective plate; the protective plate is arranged on one side, far away from the battery module, of the protective cover body and can cover the flow guide hole; when the battery module is in a normal working state, the protective plate covers the flow guide hole; and when the single battery anti-explosion valve is exploded, an airflow channel is formed between the protective plate and the protective cover body. And the situation that the safety of passengers and articles in a passenger compartment is endangered when the single battery anti-explosion valve is exploded can be improved.

Description

technical field [0001] The present application relates to the field of battery technology, in particular, to a fire protection cover and a battery module. Background technique [0002] In the prior art, battery modules are generally equipped with single battery explosion-proof valves. One way is to set the single battery explosion-proof valves upwards, that is, towards the upper cover of the battery pack and the passenger compartment; when one or more of the battery modules When the thermal runaway of a single battery occurs, when the explosion-proof valve of the single battery explodes, flames, high-temperature media, and high-temperature gas with a certain impact are sprayed from the explosion-proof valve directly to the protective cover, and the impact of the gas is easy to make the protective cover The cover was punctured and sprayed directly to the upper cover of the battery pack and the passenger compartment, igniting the vehicle and endangering the safety of the occup...
