A battery compartment throwing away structure of a battery-swapping electric vehicle

Abstract

The invention relates to the technical field of new energy vehicle equipment, and discloses a battery compartment throwing away structure of a battery-swapping electric vehicle, including a chassis, the bottom of which is embedded with a battery compartment, and one side of the battery compartment is provided with a row Air pipe, the battery compartment is provided with a sensor for monitoring whether the battery is burning. The battery compartment throwing away structure of the battery-swapping electric vehicle, when the spontaneous combustion of the battery is detected, a large amount of nitrogen gas is released instantly through the ignition of the gas production device, and the battery compartment and the connection compartment are thrown out as a whole through the sharp change of the air pressure. Avoid the battery catching fire and igniting the car, causing greater loss of personnel and property. Secondly, it can quickly extinguish the open flame, and at the same time suppress the temperature in the battery compartment, effectively avoiding the secondary re-ignition of the battery, and reserve enough time for the battery to be thrown out. After being thrown out, the battery is kept away from the vehicle but not completely separated from the vehicle, which is convenient for controlling the throwing position of the battery and reducing the additional impact.

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.
