Battery compartment throwing structure of battery replacement type electric automobile

Abstract

The invention relates to the technical field of new energy automobile equipment, and discloses a battery compartment throwing structure of a battery replacement type electric automobile, which comprises a chassis, a battery compartment is embedded in the bottom of the chassis, an exhaust pipe is arranged on one side of the battery compartment, and a sensor for monitoring whether a battery burns ornot is arranged in the battery compartment. According to the battery compartment throwing structure of the battery replacement type electric automobile, when it is detected that a battery spontaneously combusts, a large amount of nitrogen is instantly released through ignition of the gas production device, the battery compartment and the connecting compartment are integrally thrown out through rapid change of air pressure, and the situation that the battery is on fire to ignite the automobile, and consequently larger personnel and property losses are caused is avoided, and moreover, open firecan be rapidly extinguished, meanwhile, the temperature in the battery bin is restrained, secondary reburning of the battery is effectively avoided, enough time is reserved for throwing out of the battery, after the battery is thrown out, the battery is far away from a vehicle and is not completely separated from the vehicle, the throwing-out position of the battery can be conveniently controlled, and extra influences are reduced.

For electric vehicles, battery charging time consumption and battery life are difficult bottlenecks to break through. Therefore, some car manufacturers have introduced battery-swapping electric vehicles to overcome insufficient battery life and long charging time by providing battery replacement services. The problem

[0003] Existing electric vehicles usually use lithium batteries. Lithium batteries are made of flammable organic electrolyte solutions and active lithium metals, and have high battery energy density. Spontaneous combustion or even explosion occurs. Since lithium batteries are usually installed in the vehicle chassis, and the battery spontaneously ignites very quickly, it often ignites the vehicle before it can react, resulting in greater loss of personnel and property, and a greater potential safety hazard.

[0004] On the other hand, since the combustion of lithium batteries is often caused by the violent chemical reaction of its internal substances, it is difficult for the usual fire extinguishing methods to go deep into the interior and to extinguish it completely. After the fire is extinguished, it will re-ignite quickly. Therefore, if you want to completely extinguish the fire, you often need to wait until the battery is completely burned or soaked in water. Therefore, when the battery is natural, it is usually difficult to eliminate the problem in time and affect the rear vehicles.
