Thermal imaging camera to monitor the safety of EV charging stations

A thermal camera is the only diagnostic technology that can instantly visualise and verify thermal information. As the new energy vehicle industry has entered a new stage of accelerated development, public awareness of environmental protection is gradually improving and deepening ecological civilisation construction.

With the increased use of electric vehicles, the number of supporting charging stations has also increased. To shorten the charging time of users, charging piles generally use high-voltage and high-current working methods, which put forward extremely
high requirements for safety.

Electric vehicle charging piles can be divided into indoor and outdoor forms. Generally speaking, outdoor charging piles are mostly public charging piles, and indoor charging piles are mostly private charging piles. No matter what kind of charging pile, there will be potential safety hazards such as line ageing and leakage, and a fire or a larger safety accident will likely occur. At the same time, most of them are located in densely populated places.

At present, traditional fire-fighting systems mostly use traditional smoke-sensing, temperature measurement and other technologies, all of which are post-disaster alarm technologies. It cannot be prevented beforehand and will cause heavy losses to the safety of people’s lives and property.

How to give early warning in the temperature rise stage and smouldering stage of fire, eliminate hidden dangers in the bud, and truly turn “passive monitoring” into “active prevention”? A thermal camera is the only diagnostic technology that can instantly visualise and verify thermal information. It has a unique temperature measurement capability and can accurately detect the
temperature change of the charging interface and line surface before an accident occurs. An alarm is issued to achieve early warning, and the fire protection system is linked to preventing fires.

Thermal camera for monitoring.
24h real-time monitoring A thermal camera can provide non-contact accurate temperature measurement and realtime monitoring of the charging process. The monitoring of the surface temperature distribution of the charging pile and the output of temperature image distribution and data are performed at the same time. Thermal cameras can also provide online temperature measurements
of the charging pile 24 hours a day while monitoring the input and output overvoltage and Undervoltage, etc. Insulation detection fault, leakage, over temperature, short circuit and other faults will be alarmed to ensure its safe operation.

Diverse and accurate temperature measurement
In the process of real-time monitoring, especially for the high-temperature hidden danger areas such as connecting cables, electric boxes, charging gun heads, and various contact points of line terminals, a thermal camera supports drawing multiple monitoring areas according to the monitoring targets and conducts real-time monitoring and temperature measurement of key areas. In order to timely detect high-temperature thermal hazards.

Prevent from Burning
Compared with traditional smoke detectors, a thermal camera can be used in fire prevention to realise early warning. High-temperature points can be found by the temperature measurement function in the heat accumulation stage and smouldering stage before the fire, and abnormal temperature changes caused by charging failures can be sensed. Prevent from burning.

Accurate fire positioning
A thermal camera can penetrate and can pass through the thick smoke caused by combustion. Even in an environment without light, it can still accurately locate the ignition point by temperature measurement function. When a fire accident occurs, it can help rescuers put out the fire quickly.
Intelligent Linkage Fire Extinguishing
Real-time temperature measurement and monitoring of the charging pile (highest temperature, lowest temperature, average temperature) and fire point monitoring. Once an early warning is issued, the thermal camera will automatically associate with peripheral equipment, perform alarm snapshots and videos, and provide data support for event tracing. At the same time, it outputs alarm signals to support and the third-party equipment cooperates with the application to realise the function of sound and light alarm and firefighting linkage, and complete the fire extinguishing or suspend work.
