Technical Field
The utility model relates to a square extinguishing device suitable for new energy automobile battery box belongs to fire control technical field.
Background
The rapid development of new energy automobiles is a basic national policy of energy policies in China and the reduction of environmental pollution. Since 2009, many commissions have frequently issued documents to support the development of new energy vehicles. For example, the state service institute issues 'decision on accelerating cultivation and developing strategy emerging industry' in 2010, and officially lists new energy vehicles in one of seven strategic emerging industries. In recent years, new energy vehicles, especially electric buses, have been developed greatly, and many cities invest huge capital for using new energy buses.
The new energy automobile uses a lithium storage battery as a power battery. When the lithium ion battery is abused or is subjected to external environmental factors or forms short circuit and other quality problems due to the fact that the lithium ion battery penetrates through a membrane, the phenomena of leakage, air release, smoke generation and the like can occur, and burning and explosion can occur in serious cases. The main flow dynamic battery in the current market is a cobalt acid lithium battery and a ternary lithium battery (nickel cobalt lithium manganate). The technical means is adopted during the design and manufacture of the battery, the occurrence of fire is limited to the greatest extent, but in the using process, the phenomenon of spontaneous combustion of the automobile caused by the ignition of the power lithium battery still occurs at all times, and according to incomplete statistics, 29 new energy automobiles are reported to be ignited in 2016, and the total number of the new energy automobiles is 40.
Most electric vehicles are not equipped with a dedicated fire extinguishing device for the battery box. Once the battery is on fire, the electric automobile can spontaneously ignite, so that the economic loss is huge (about 200 ten thousand for one electric bus), and the fatal potential safety hazard can be brought to passengers.
This phenomenon has attracted much attention from the national authorities. In 2015, a public transport department issues implementation opinions about accelerating popularization and application of new energy automobiles in the transportation industry by transport department (2015)34, and a special fire extinguishing device is required to be arranged in a battery box; the 'automatic fire extinguishing device special for the power battery' is also definitely brought into a grade evaluation project in 'new energy passenger car grade evaluation supplement requirements'.
