Description

Automatic rotating battery compartment replacement cabinet with fire protection function

【Technical field】

The invention relates to the technical field of battery replacement, and in particular to an automatic rotating battery compartment power replacement cabinet with a fire protection function.

【Background technique】

Existing power swapping cabinets charge the batteries placed in their battery charging compartments. The internal space of the power swapping cabinets is limited. In order to charge more batteries at the same time, the battery charging compartments are often designed to be small in space and compact in structure. The overall structure only allows one battery to be charged; the battery will generate a large amount of heat when charging. If this heat cannot be dissipated in time, it will accumulate in the battery charging compartment, which will easily cause the temperature of the battery in the charging compartment to rise. , the battery will burn or even explode; in order to prevent the above accidents, existing power swap cabinets are equipped with fire extinguishers to extinguish open flames generated by battery burning.

The batteries charged in the power swap cabinet are generally lithium batteries. The ignition and combustion of lithium batteries is energy-type discharge ignition and combustion with a delay. After the aerosol fire-extinguishing material stored in the fire extinguisher is sprayed, the energy in the lithium battery is still there. There is no complete discharge, but as the aerosol fire-extinguishing material volatilizes and the oxygen gradually recovers, the lithium battery will undergo secondary combustion or even explode, eventually causing a serious fire.

The fire source of the battery replacement cabinet is the battery. If the battery catches fire, if you use an inert gas or dry powder fire extinguisher to extinguish the fire, you will not be able to effectively extinguish the fire, because when the battery core catches fire, there will be a chemical reaction inside and it will produce oxygen and flammable gases. That is to say Cells can spontaneously ignite without external oxygen. Water is better than other fire extinguishing agents. In different types of chemical systems, water shows better cooling ability. If the burning battery is continuously cooled with water, effective fire extinguishing can be achieved after the battery is completely cooled. The current battery swapping cabinets on the market do not have fire protection systems. Once a battery catches fire, the fire can easily spread without being controlled in time and cause a fire, which brings great safety risks to people's lives and property.

The smart charging and swapping cabinets for electric vehicles currently used mainly charge the batteries of electric bicycles. However, most batteries on the market currently use lithium batteries. In recent years, lithium battery charging fire accidents have occurred frequently. It has brought great hidden dangers to personal safety and property safety. In order to reduce the loss of accidents caused by fire. The problem of improving the fire safety of equipment needs to be solved urgently.
