The increasing popularity of electric vehicles, charging usage, and safety are top priorities for governments, industries, and customers. During the long-term use of charging piles, occasional relay adhesion causes the power supply to fail and cannot be interrupted normally. This safety hazard is often ignored. This article will give a brief description of its possible potential hazards and the necessity of detection and diagnosis.

The relay is one of the key components of the AC electric vehicle charging pile and is responsible for controlling the on and off of AC energy transmission. However, during long-term use, the relay may have a certain probability of failure and adhesion, causing the device to continue to be powered after the charging gun is pulled out. Although this is a scenario with a low probability of occurrence, the hazards cannot be ignored:

• Not easily identifiable by users. Because the relay is stuck, the device continues to receive power. When the failure occurs, there are no obvious features on the periphery of the equipment. The live equipment is continuously exposed and accessible to the user, and there is no obvious identification reminder. This kind of safety hazard will be huge as users use it frequently every day.
• Non-household public charging facilities are often unattended, remotely monitored and managed, and such risks will increase exponentially.

How does Raedian achieve this?

The full range of smart charging pile products launched by RAEDIAN are equipped with hardware monitoring and protection circuits, software control and APP/Cloud early warning strategies for the relays in the control circuit.

RAEDIAN smart charging pile wallbox has a built-in monitoring and protection circuit. After the charging process, if it is detected that the relay is adhered and is not broken normally, an alarm will be issued through the light language and OLED screen, and charging will be prohibited, effectively preventing subsequent accidents. At the same time, fault information is immediately uploaded to the cloud and APP, and customers are immediately reminded to cut off power and perform necessary equipment repairs or replacements. If it is a public charging pile, based on the reported data, safety risks will be given the highest priority, and the charging station operation and after-sales service personnel will be reminded to handle them in a timely manner.

What Raedian can bring to EV charging?

The danger of relay adhesion is an important matter that cannot be ignored for the safe operation of charging piles. The ubiquitous charging piles are closely related to everyone’s life and safety. Whether it is for the safety and protection of car owners or to help operators improve the efficiency of remote operation and maintenance of charging stations and reduce operating costs, it is very important.

When designing and manufacturing each charging pile, RAEDIAN fully considers relay adhesion protection and is 100% factory inspected. The APP will have a dedicated interface to receive safety inspection results in real time and push them to customers in a timely manner to ensure that it can provide car owners with the best service. Smart and efficient charging experience.
