The invention provides a non-pressure-storage type lithium battery fire automatic fire extinguishing device which comprises a shell, a nozzle and a fuel gas driver arranged in the shell. The shell isfilled with a fire extinguishing agent, the nozzle is arranged on the surface of the shell and communicates with the interior of the shell, and the fuel gas driver comprises a shell, an igniter and agas generating agent filled into the shell, the igniter is arranged at the top of the shell and is connected with a thermosensitive line, the thermosensitive line is in contact with the gas generatingagent in the shell, and a plurality of gas generating ports are formed in the surface of the shell. According to the automatic fire extinguishing device, when thermal runaway occurs in an electric vehicle power battery system or an energy storage power station, rapid start and spray can be achieved, the fire extinguishing agent can be scattered, a power battery fire can be effectively restrained,thermal expansion of a power battery is delayed or prevented, and the non-pressure-storage type lithium battery fire automatic fire extinguishing device has high practical application values.
Description
technical field [0001] The invention belongs to the field of lithium battery safety protection, and in particular relates to a non-pressure storage automatic fire extinguishing device for lithium battery fires. Background technique [0002] Lithium batteries have been widely used in electric vehicles, electrochemical energy storage power stations, electric bicycles and other fields due to their advantages of cleanliness, high efficiency and reusability. They have broad development prospects and great market demand. A lithium battery is a chemical energy storage device that is susceptible to thermal runaway caused by external stimuli or its own manufacturing defects, which can then lead to fire, combustion, or even explosion. [0003] During the development of electric vehicles, there have been hundreds of fire accidents such as Hangzhou pure electric taxi spontaneous combustion accident, Shenzhen pure electric taxi was hit and caught fire, Tesla spontaneous combustion fire, ...
