The research and development of automatic fire extinguishing system and PFH automatic fire extinguishing device for new energy lithium battery vehicles are based on the characteristics of lithium battery fires in new energy vehicles, which effectively solve the fire accidents caused by lithium battery thermal runaway during the use of new energy vehicles, as well as the difficult problem of lithium battery fire fighting that is easy to re ignite. Technical treatment and improvement have been made in fire detection, suppression, elimination and anti re ignition, It effectively improves its fire detection ability, makes the fire extinguishing more efficient and fast, and realizes the automation, intelligence and efficiency of new energy vehicle fire.

Lithium battery is widely used in the field of new energy vehicle power battery because of its light weight, high energy density, green environment and other characteristics, and has become the leader in the field of new energy vehicle battery. However, in the process of its use, lithium batteries often cause fire accidents due to overcharge, overdischarge, thermal runaway and other reasons. The lithium battery of new energy vehicles is fast in fire, easy to deflagrate, fierce in fire and long in burning time. The traditional fire extinguishing mode is difficult to control the occurrence or spread of fire, and in the process of cooling, it is not only easy to re ignite, but also slow in cooling and long in extinguishing time, thus promoting the application of perfluorohexanone automatic fire extinguishing device with high quality, high performance and high reliability.

As a small, low-cost and highly reliable independent automatic fire extinguishing system, the automatic fire extinguishing system/device for new energy lithium battery vehicles can realize effective fire detection by setting the temperature in the protection space, realize rapid, accurate and effective monitoring of fire in the protection area, integrate alarm and fire extinguishing, and realize effective fire extinguishing at the initial stage of a fire.

Perfluorohexanone automatic fire extinguishing system/device for new energy vehicles can not only greatly reduce the project cost, but also reduce the cost of each fire fighting without causing any harm to personnel. Moreover, the use of fire extinguishing devices can also realize full flooding fire extinguishing in narrow and complex spaces, and achieve no dead angle and accurate spraying fire extinguishing in protective spaces, making up for the shortcomings of existing fire extinguishing products that cannot effectively extinguish such fire sources.
