Electric Vehicle Charging Pile Electrical Fire Monitoring System

Background Overview

Electric vehicles, as a sustainable alternative to gasoline vehicles, have become a social consensus. In recent years, the number of electric vehicles and charging stations has grown rapidly. However, incidents of fire and combustion caused by electric vehicle charging stations are also highly frequent. According to the analysis of the cause of the accident, in addition to safety risks such as improper equipment installation, untimely maintenance, or non compliant charging behavior, the quality problems of the product itself are the key risk factors, mainly manifested in the following aspects:

1) Leakage risk: ① There are defects in the anti electric shock protection. ② Not equipped with residual current protector, or improper selection of residual current protector type. ③ The equipment does not have insulation detection function and grounding continuity detection function.

2) Short circuit risk: ① Low insulation resistance and decreased insulation performance may lead to phase to ground short circuit or equipment to ground short circuit, and in severe cases, there may be a fire hazard. ② The failure of overcurrent protection function can easily lead to overheating of the charging circuit, and even burn damage to the insulation layer of the output cable, posing a risk of short circuit.

3) Fire risk: ① Overloading protection device specifications are too large, which can easily cause overheating and even fire hazards in the charging circuit, including charging cables and connection points, and cannot provide protection. ② The power supply and vehicle sockets lack over temperature protection.

For the above quality issues, it is necessary to consider fully configuring electrical fire monitoring equipment at the charging station. By monitoring the remaining current, temperature, fault arc and other parameters of the electrical circuit in real time, fire warnings can be issued in advance or current limiting protection can be activated to prevent problems before they occur.

System Overview

Electric Vehicle Charging Pile Electrical Fire Monitoring SystemThe electric fire monitoring system for charging stations or charging piles is mainly built by taking charging stations or charging piles in parking lots as objects, installing electrical fire protection current limiting protectors, networking directly or through gateways, and connecting cloud platforms through mobile Internet.

The main implementation of this system is: 1) Through the current limiting protection function, when a short circuit fault occurs in the backend circuit of the protector, the protector can automatically start the current limiting protection within 150us to trip and cut off the power, avoiding electrical fires caused by short-circuit arcs. 2) Through the residual current monitoring function, when the residual current exceeds the set value in a timely manner, the current limiting protection or alarm can be selected to be turned on. 3) Through overload and cable temperature monitoring functions, when overload or high cable temperature is detected in a timely manner, current limiting protection or alarm can be selected to be turned on. 4) By real-time monitoring of parameters such as current, voltage, power, residual current, and temperature in electrical circuits, we provide users with uninterrupted data change tracking, statistical analysis, and safety monitoring services. The platform promptly pushes various safety hazard information discovered to relevant personnel for easy investigation and handling, early elimination of hazards, and formation of a closed loop of O2O business management, effectively avoiding the occurrence of electrical fire accidents and truly preventing them before they happen.
