What is the reason for the red warning light flashing on the charging pile?

The red warning light flashing on the charging pile indicates that the converter of the charger is damaged and cannot convert or charge, requiring replacement of the charger resistor. Below are methods to protect your electric vehicle charger: Choose an appropriate location: It is best to charge the battery in a cool, ventilated, and dry place. Direct sunlight or rain can adversely affect the performance of both the battery and the charger. During charging, keep the battery and charger away from other heat sources. Charge promptly: The battery should be fully charged immediately after use, indicated by the charger's green light. Storing the battery with insufficient charge for a long time or using it before it is fully charged will affect the battery's performance. Using the battery 3 hours after the charger's green light turns on yields the best results.

Last week, I encountered a red flashing light on the charging pile, which really worried me. After careful troubleshooting, the most likely issue was poor communication between the charging pile and the car, such as the charging gun not being inserted tightly or dirt on the car's charging port. Another possibility is that the charging pile itself malfunctioned, such as internal circuit overheating triggering protection, especially when exposed to direct sunlight in summer. It could also be due to unstable power supply at home, with fluctuating voltages causing the charging pile to alarm. It's recommended to first completely power off and restart the charging pile, then thoroughly clean the charging port. If the red light continues to flash, you should contact the manufacturer's after-sales service.

I've seen many cases of charging piles showing red lights, with common issues concentrated in a few areas. The failure rate of the charging equipment itself is quite high, especially for older piles used for more than three years—aging motherboard components tend to trigger alarms. Power supply issues are another concern; nowadays, too many electric vehicles charging simultaneously in residential areas can overload the grid, leading to unstable power supply. Connection line problems are also frequent, particularly for ground lines that are often stepped on, which can easily lead to exposed wires and short circuits. If you can't identify the cause, it's recommended to disconnect the charging pile's power and open its maintenance panel—there's usually an indicator code table. A display of E10 typically indicates a communication fault, while E05 is mostly due to overheating protection.

The flashing red light on the charging pile indicates that it has detected an abnormality, which requires immediate attention. Focus on inspecting three key aspects: First, the connection status between the charging gun and the vehicle's port, as dust accumulation on the metal contacts can lead to poor contact. Second, the power supply line environment, such as voltage fluctuations exceeding the 200-250V range, which can trigger protection mechanisms. Third, the charging pile itself, where overheating or failure of the internal lightning protection module can cause an alarm. Typically, troubleshooting in sequence is sufficient—start by reinserting the charging gun, then check the household voltage, and finally consider faults in the pile body. Safety is particularly crucial in this situation; never directly touch live components with your hands.
