Vehicle-mounted battery fireproof heat source management synchronization device and use method

Abstract

The invention relates to a vehicle-mounted battery fireproof heat source management synchronization device and a use method. The device comprises a liquid storage device, a liquid storage device control valve, a fire extinguishing pipeline, a spray head or a spray hole, a fire extinguishing pipeline control valve, an inductive probe, a water inlet connecting pipe and a water outlet connecting pipe, a sealed circulating flow channel is formed among the heat exchange pipeline, the water inlet connecting pipe, a vehicle-mounted battery pack module and the water outlet connecting pipe, fire extinguishing heat exchange liquid is stored in the liquid storage device, and the liquid storage device control valve, the fire extinguishing pipeline control valve and the inductive probe are all connected with a vehicle-mounted computer controlling the heat source management system and the vehicle-mounted battery pack module and are synchronously controlled by the vehicle-mounted computer. The vehicle-mounted battery fireproof heat source management synchronization device is ingeniously combined with an existing vehicle-mounted battery heat management system; under the condition that normal operation of an existing vehicle-mounted battery thermal management system is kept, professional fire extinguishing equipment of a battery module is omitted, the integration degree of resources is improved, the structural layout of the whole vehicle is simplified, the requirement for light weight of the whole vehicle is met, cost is saved, and the working mileage of the whole vehicle is increased.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to a synchronization device for fire prevention and heat source management of a vehicle-mounted battery and a method for using it. Background technique [0002] In the development of new energy vehicles, the battery thermal management system water cooling unit (TMS) is used to control the battery operating temperature to improve the service life and efficiency of the battery, and the battery intelligent fire protection component (EMS) is used to deal with combustion caused by battery failure; two The device is arranged on the whole vehicle, resulting in too many equipments on the whole vehicle, high cost, cumbersome structural layout, heavy weight, too many CAN signals of the whole vehicle, easy downtime, high maintenance cost, and short mileage of the whole vehicle, etc., two independent The control system is cumbersome and cannot be synchronized and coordinated, and ...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no intelligent control device on the market that can control the heat source of the battery, and can extinguish the fire in time when the battery or the whole vehicle fires; Not yet, so in view of this problem, it is necessary to develop a device for synchronous management of vehicle battery fire protection and heat source
