Changing the norm. Charging the future

1. Charging startup failure

When the charging station does not respond or the screen goes black, first check whether the circuit breaker in the distribution box has tripped. If necessary, reset it and observe the status of the device indicator light. If there is still no response, try performing a basic restart: press and hold the emergency stop button for about 5 seconds, then release it, unplug the charging gun, wait a moment, and reconnect it.

If the charging gun cannot be inserted, check if the metal contacts on the gun head have dust or oxidation. You can gently wipe them clean with an eraser. Also, check if the vehicle interface has minor deformation. If necessary, manually adjust it. If the deformation is severe, it is recommended to replace the interface components.

2. Charging Interruption Issues

If a power outage or circuit breaker trip occurs during charging, common causes include leakage protection activation or power overload. It is recommended to first inspect the charging cable for insulation damage and ensure the grounding resistance does not exceed 10Ω. Additionally, verify that the charging station’s rated power matches the circuit breaker specifications; for example, a 100kW device should be paired with a 125A or higher circuit breaker to ensure stable load capacity.

Some vehicle models may experience “abnormal disconnection” during charging, which may be caused by protective interruption due to high battery temperature. Typically, the system will automatically pause when the temperature exceeds 50°C. In such cases, simply wait for the battery to cool down before reconnecting. If temperature is ruled out as the cause, focus on checking whether the BMS communication protocol is compatible with the charging station, especially when connecting a new vehicle model for the first time. Additionally, it is recommended to confirm whether the charging gun’s locking mechanism has any mechanical issues such as jamming to rule out hardware problems.

3. Abnormal charging efficiency

If you notice a significant slowdown in charging speed during the charging process, it may be related to the device’s operating status, grid conditions, or the vehicle’s battery condition. For example, when both charging ports are in use simultaneously, the system automatically distributes power, and a halving of the current is a normal phenomenon. Additionally, if the supply voltage is below 200V, it may also affect charging efficiency. It is recommended to contact the local power authority for inspection.

Low temperatures can also cause charging speeds to decrease. When the battery temperature is below 0°C, the system automatically limits the charging current to protect the battery, thereby extending the charging time.

As for failed trickle charging, this is typically caused by the vehicle’s own control strategy. When the battery current remains below 10A for over 10 minutes, some vehicle models will automatically terminate charging. This phenomenon is not caused by a charging station malfunction and does not require additional action.

5. Handling of emergencies

In rare cases, users may encounter emergency situations such as device abnormalities or charging gun jamming. If the charging gun cannot be pulled out, first confirm whether it is currently in AC or DC charging mode. For AC pile, generally only need to wait for about one minute after the vehicle is unlocked, after the voltage is automatically released, it can be pulled out smoothly. If it is a DC pile, you can use the supporting key to insert it into the object comprehension lock hole on the side of the gun and gently rotate it to complete the unlocking.

If you find smoke or burning odor from the device, be sure to press the emergency stop button at the first time, cut off the main power supply, and contact a professional as soon as possible to report for repair. Such problems may involve overheating of internal components or short-circuiting of wiring, do not operate without authorization.
