Fire-fighting box for vehicle battery, battery compartment mechanism and battery replacement system

Abstract

The invention relates to a fire-fighting box for a vehicle battery. The fire-fighting box comprises a flame-retardant box; the flame-retardant box comprises a second box body and a first box body; the second box body and the first box body are isolated through a movable baffle; a flame-retardant substance is stored in the second box body; the first box body is used for putting the vehicle battery; and a limiting part for limiting the movement of the baffle is arranged in the first box body. The invention also relates to a battery compartment mechanism and a battery replacement system. The vehicle battery is put into the first box body, the battery touches the limiting part, the limiting part drives the baffle, then the flame-retardant substance in the second box body falls to cover the battery in the first box body, the combusted battery is covered with the flame-retardant substance to isolate oxygen, and meanwhile the flame-retardant substance absorbs heat on the surface of the battery to achieve a fire extinguishing effect, and fire accidents caused by spontaneous combustion of the battery are avoided.

Description

technical field [0001] The invention relates to the technical field of battery replacement for electric vehicles, in particular to a fire box for vehicle batteries, a battery compartment mechanism and a battery replacement system. Background technique [0002] The development of pure electric vehicles is becoming more and more rapid. One of the bottlenecks hindering the development of pure electric vehicles is the charging problem of power batteries; the traditional method is to use charging piles to charge quickly, but this method has many disadvantages: the efficiency is not as fast as refueling, and the battery usage is reduced The cost of life and battery maintenance is high. In order to solve the efficiency problem, the existing solution is to replace the battery on the electric vehicle directly by replacing the battery, replace the fully charged battery from the replacement station, and replace the deficient battery and charge it at the replacement station, which impro...

[0002] The development of pure electric vehicles is becoming more and more rapid. One of the bottlenecks hindering the development of pure electric vehicles is the charging problem of power batteries; the traditional method is to use charging piles to charge quickly, but this method has many disadvantages: the efficiency is not as fast as refueling, and the use of batteries is reduced. Long life and high cost of battery maintenance

In order to solve the efficiency problem, the existing solution is to replace the battery on the electric vehicle directly by replacing the battery, replace the fully charged battery from the replacement station, and replace the deficient battery and charge it at the replacement station, which improves the efficiency of electric vehicles. The most important thing is to improve the efficiency and reduce the waiting time for charging. Because the battery needs to be disassembled and assembled, it generally needs to be completed in the battery swap station, and there are a large number of batteries stored in the battery swap station. However, there is a safety hazard (thermal runaway) in the battery itself. If it cannot be disposed of in time, the battery burns and emits toxic gas that will pollute the environment and cause damage to the human body, and cause a fire in the replacement station. A large number of batteries will be destroyed. The consequences are more serious, and a device that is convenient to isolate and extinguish the abnormal battery (which tends to burn or has spontaneously ignited) is needed
