Electric vehicle battery fire extinguishing monitoring system and charging pile

Abstract

The invention discloses an electric vehicle battery fire extinguishment monitoring system and a charging pile. The system comprises the charging pile connected with an electric vehicle. The charging pile comprises a fire extinguishing device and a temperature monitoring system arranged in a charging pile body, wherein the temperature monitoring system is used for collecting temperature signals of a battery in the electric vehicle and controlling the fire extinguishing device to spray out fire extinguishing agents to cool the battery or extinguish a fire when temperature values corresponding to the temperature signals exceed a preset temperature threshold value. The charging pile of the electric vehicle battery fire extinguishment monitoring system conducts real-time monitoring on the battery of the electric vehicle under charging, and the fire extinguishing device is used for extinguishing the fire of the battery or cooling the battery when the battery of the electric vehicle is abnormal, so that losses caused by abnormity of the battery of the electric vehicle are greatly reduced, safety and controllability are achieved, and cost is low.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle battery fire extinguishing monitoring system and a charging pile. Background technique [0002] At present, with the promotion of low-carbon travel, electric vehicles are becoming more and more popular. Compared with the use of traditional fuel vehicles, electric vehicles need frequent charging. [0003] While electric vehicles bring convenience to people's travel and environmental protection, there are also potential safety hazards, such as electric vehicle fires, including fires during charging, collisions, and normal discharges. Since there are protective measures and the battery is operated in a low-energy range, there are fewer fires during normal discharge, and it is easier for personnel to escape or rescue in this case. [0004] However, for charging and igniting, since the battery charging of the electric vehicle is often unattended, during ...

AI Technical Summary

Problems solved by technology

[0004] However, for charging and igniting, since the battery charging process of the electric vehicle is often unattended, therefore, during the charging process, if the battery of the electric vehicle catches fire, the battery cannot be extinguished in time, which will cause Great loss for users
