Electric Vehicle Charging Shed Electrical Fire Monitoring System

background

Charging electric vehicles has become a part of people's daily lives. However, the charging safety issues of electric vehicle charging sheds are becoming increasingly prominent. Especially in recent years, the number of fires caused by electric vehicle shed charging has remained high nationwide, resulting in heavy losses and causing great sorrow. After analyzing the causes of the accident, in addition to non-standard equipment installation and quality issues with the electric vehicle itself, there are also the following main reasons:

1) Improper management, such as dense vehicles and complex environment in the area, lack of daily inspections, serious inadequate management, and numerous safety hazards;

2) Lack of technical means, such as outdated equipment and facilities, especially safety hazards in charging lines and early overheating or smoke anomalies in vehicles and other equipment, lack of monitoring and prevention measures, and inability to timely warn or control any potential danger; In addition, the lack of intelligent fire extinguishing devices makes it impossible to achieve automatic fire extinguishing when active.

In response to the above issues, it is urgent to adopt effective technical measures to solve the problem of electrical fire prevention and control, in addition to improving the quality of electric vehicles and strengthening the safety inspection and supervision of charging sheds.

System Overview

Electric Vehicle Charging Shed Electrical Fire Monitoring SystemTaking the charging shed area and its main distribution box as the object, a set of intelligent electrical fire monitoring system with the function of "fire prevention integration" is built by adding thermal imaging heat detectors, hanging fire extinguishing devices and electrical fire protection current limiting protectors, networking directly or through the gateway, and connecting to the cloud platform through the mobile Internet.

This system is based on self-learning AI technology, which detects abnormalities through all-weather electrical parameter monitoring, thermal imaging temperature monitoring, and intelligent smoke recognition. It promptly activates warning or microsecond level current limiting short circuit protection, and in severe cases, activates intelligent fire extinguishing devices to achieve safety monitoring and management of electric vehicle charging sheds.

This system promptly pushes various safety hazard information discovered to relevant personnel, facilitating timely investigation and handling, early elimination of hazards, and forming a closed loop of O2O business management, effectively avoiding accidents and truly achieving prevention before they happen. The specific structural diagram is shown in the following figure

System functions

1. Electrical protection: Provides microsecond level fast short-circuit power-off protection, overload protection, leakage protection, and over temperature protection, etc;

2. Intelligent monitoring: thermal imaging and intelligent recognition of abnormal temperature, smoke, flames, and other characteristics of vehicles and other objects in the detected area, and timely issuance of warning and alarm signals when abnormalities are detected;

3. Automatic fire extinguishing: When a fire occurs and the ignition temperature is detected, reaching the melting point, the corresponding fire extinguishing device will automatically start, effectively ensuring the fire safety of the electric bicycle shed and surrounding areas;

4. Intelligent alarm: View real-time data, device status, alarm events, hidden danger handling records, etc. online, and notify users of alarm information through pop ups, emails, SMS, phone calls, APP push notifications, WeChat mini program push notifications, etc;

Applicable occasions and system value

Electric Vehicle Charging Shed Electrical Fire Monitoring SystemWidely applicable to electric vehicle charging sheds and indoor parking lots equipped with charging facilities. Through this system, the safety risks caused by non-standard management of charging sheds and quality issues of electric vehicles and charging facilities have been compensated for, effectively avoiding the occurrence of fires and preventing casualties and property losses. Through O2O innovative management mode, remote monitoring has been achieved, which not only improves the speed of identifying and handling accident hazards, but also greatly enhances the level of operation and management of charging sheds.
