Rapid fire extinguishing and cooling system for battery pack

Abstract

A rapid fire extinguishing and cooling system for a battery pack comprises the battery pack, a temperature and smoke sensor, a fire extinguishing and cooling pump, a conveying pipeline, a cooling andfire extinguishing material box and a control device. The battery pack comprises a plurality of battery packs which are connected in series or in parallel, and a sealed shell coating the outer sides of the battery packs. The temperature and smoke sensor is arranged in the sealing shell and used for detecting the temperature value and the smoke concentration value in the sealing shell. One or moreof a cooling material and a fire extinguishing material are contained in the cooling and fire extinguishing material box. The control device starts the fire extinguishing and cooling pump according tothe temperature value output by the temperature and smoke sensor and the smoke concentration value, so that the fire extinguishing and cooling pump drives the fire extinguishing or cooling material to enter the sealed shell for fire extinguishing or cooling. The rapid fire extinguishing and cooling system for the battery pack can provide enough time for drivers and passengers to escape from the vehicle, so that life and property loss is avoided.

Description

Technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a rapid fire extinguishing and cooling system for battery packs. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), including pure electric vehicles, extended-range electric vehicles, hybrid vehicles, and fuel cells Electric cars, etc. But no matter which type, it will use battery packs to store energy to provide continuous power to the car. [0003] However, with the development of technology and industry, the safety of battery packs has become a key technology in new energy vehicles. Because the battery pack is usually composed of multiple battery pieces combined into a battery pack, and then composed of multiple battery packs. The power of the battery pack is often determined by the number of battery packs. However, in da...

AI Technical Summary

Problems solved by technology

However, in such a short period of time, especially during the driving process of the vehicle, it is often difficult for the user to find out, resulting in the spontaneous combustion or explosion of the vehicle, and the loss of life and property caused by the lack of time for the drivers and passengers to escape.
