Problems solved by technology

[0005] The above reactions are all exothermic reactions, and the heat released by the reaction will further increase the internal temperature of the battery to 110°C to 120°C, which will cause the SEI film to lose its protective effect on the negative electrode of the lithium-ion battery.

Abstract

The invention relates to the technical field of vehicle power battery fire fighting, in particular to a vehicle power battery thermal runaway intelligent fire fighting device and an automobile. Comprising a battery shell, a pipeline mounted above the battery shell, an electric control water mist nozzle arranged on the pipeline, a high-pressure water-based fire extinguishing pump, a water-based fire extinguishing agent storage tank connected with the high-pressure water-based fire extinguishing pump, a temperature sensor, a gas sensor and a control unit, the control unit is electrically connected with the electric control water mist nozzle, the high-pressure water-based fire extinguishing pump, the temperature sensor and the gas sensor; the device is simple and practical, can effectively solve the fire safety problem when the power battery is in thermal runaway, and protects the vehicle and personal safety to the greatest extent.

Description

technical field [0001] The invention relates to the field of vehicle power battery fire protection technology, in particular to a vehicle power battery thermal runaway intelligent fire protection device and an automobile. Background technique [0002] In recent years, with the progress of my country's economy and society and the concept of green and healthy development has become more and more popular, lithium-ion batteries have been widely used. So far, smoke, fire and even explosion accidents of lithium-ion batteries have occurred from time to time, posing a huge threat to the lives and property of relevant personnel, and most of these accidents are caused by thermal runaway of lithium-ion batteries . Therefore, it is necessary to use a power battery thermal runaway intelligent fire protection device for vehicles to carry out fire protection in time when the battery thermal runaway occurs, so as to avoid greater harm to vehicles and personnel. [0003] Generally, the all...
