Emergency handling device for power battery of new energy vehicle and operation method thereof

Abstract

The invention discloses an emergency handling device for the power battery of a new energy vehicle and an operation method thereof. The emergency handling device is novel in structure, good in fire control effect, capable of solving the problems of discharging of power batteries and small in occupied land area. The emergency handling device comprises a base, a water tank, columns, a lifting mechanism and a supporting and raising mechanism, wherein the columns are fixedly connected with the base and are fixed to the rear side of the base, and the lower parts of the columns abut against the rearside surface of the water tank; the supporting and raising mechanism is connected with the lifting mechanism; the front end of the supporting and raising mechanism has a raising support arm capable of supporting and raising a power battery; the raising support arm of the supporting and raising mechanism reciprocates between a first position and a second position in virtue of the lifting mechanism; and fire extinguishing liquid in the water tank is a saturated saline solution. The emergency handling device of the invention has the water tank which allows the power battery to be completely immersed, and the water tank is filled with the saturated saline solution, so the discharging of the power battery is assisted while a fire is extinguished, the power battery is protected from secondary dangerous cases, and remarkable handling effect is obtained.

Description

technical field [0001] The invention relates to the technical field of power batteries of new energy vehicles, in particular to an emergency treatment device for treating the power batteries of new energy vehicles and preventing the expansion of crises when the power batteries of new energy vehicles catch fire. Background technique [0002] With the advancement of science and technology and the development of society, more and more new energy vehicles are used. Among all kinds of new energy vehicles, the most common ones are vehicles driven by pure electric vehicles. At present, there have been several accidents where the power batteries of pure electric vehicles caught fire and exploded during use and charging. With the increase in the market share of new energy vehicles, the number of accidents involving power batteries will increase accordingly. , so how to properly deal with the power battery on fire has become an urgent new topic. [0003] But so far, the automobile OE...

Problems solved by technology

[0003] But so far, the auto OEMs have not proposed a proper way to deal with this problem

The common size of the power battery pack of a pure electric vehicle can reach 1900*1100*250mm, and the weight can reach more than 900KG. Once the power battery of a new energy vehicle catches fire, the existing treatment method is to use a fire extinguisher to extinguish the fire, but if the power is not well controlled The fire of the battery is extremely easy to cause an explosion, which will seriously endanger the health of rescuers. For automobile OEMs, where the space is small and the crowds are relatively dense, the consequences caused by the fire of the power battery of new energy vehicles are even more serious.

[0004] In addition, there are certain potential safety hazards in the existing technology to simply use fire extinguishers to fight the fire. Since the main body of the fire is the power battery of the new energy vehicle, the battery will continue to discharge during the fire extinguishing process, and there will be secondary dangerous occurrences at any time.
