Electric vehicle charging area safety early warning system

Abstract

An electric vehicle charging area safety early warning system comprises an environment detection module, environment parameters collected by the environment detection module comprise environment temperature signals and smoke signals in an electric vehicle charging area, the environment detection module transmits collected data to a control module, and the environment detection module and a charging pile are connected with the control module. The control module processes the environmental parameters, compares the acquired data signals with threshold parameters in the control module, and controls the on-off of a power supply of the charging pile according to a judgment result. A plurality of smoke and temperature sensing sensors and area temperature measuring modules are arranged in an electric vehicle charging area, temperature signals and smoke signals in the charging area are monitored in real time and transmitted to the control module, and the control module monitors the charging current and the electricity utilization power of the charging pile in real time; the control module compares the collected data with an internal threshold value, if the collected data exceed a safety threshold value, the charging pile is controlled to be powered off, and the hazard possibility is reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of electric vehicle safety monitoring, in particular to a safety early warning system for an electric vehicle charging area. Background technique [0002] With the development of society, traffic congestion and environmental pollution are becoming more and more serious. Electric vehicles have become the travel choice for most people, especially for short-distance travel in cities. Due to the mushrooming of the electric vehicle industry, and therefore Various problems of uneven quality have arisen, especially for batteries, the core components of electric vehicles, unqualified batteries are very likely to cause hazards such as spontaneous combustion, and even qualified batteries need to be charged when charging them. Take care to prevent damage from overcharging. [0003] Due to the guidance of the current government and the awareness of residents, for users living in buildings, electric vehicle charging wil...

AI Technical Summary

Problems solved by technology

[0003] Due to the guidance of the current government and the awareness of residents, for users living in buildings, electric vehicle charging will be carried out in the charging area divided by the residential property, while the existing electric vehicle charger is charging the battery of the electric vehicle. During the process, most electric vehicles do not have an automatic power-off function. In the actual charging process, when the battery is fully charged, the charger of the electric vehicle will not stop charging by itself, but will continue to output a low trickle to the battery. Current, although charging a small amount of trickle current in a short period of time will not have much impact, but if it is kept in this state for a long time, it will cause floating charge to the battery, and if it does so for a long time, it will cause serious water loss and affect the life of the battery. However, if the life of the battery is shortened, there will be quality problems. When a battery explodes due to a fault, other batteries in the charging area where it is located will cause a series of explosions, causing great harm. Today's residential areas or office buildings have no A device or system for safety monitoring of all electric vehicles in the charging area has potential safety hazards
