Operation Safety

Key Control

The key to the distribution box should be placed in the key box of the duty room (monitoring room). When changing shifts, the duty personnel need to hand over management authority of the key box and have the on-duty personnel count and verify the quantity and accuracy of keys.

Regular Inspection

During normal operation of the charging station, on-duty personnel should conduct regular inspections. In case of thunderstorms, overloads, or power shortages, the frequency of inspections should be increased. The entire charging process must be monitored continuously. Any abnormal equipment status should be promptly identified and handled correctly, with records kept and reports submitted to relevant superiors.

Waterlogging Prevention

Regularly inspecting and clearing the drainage facilities on roads and premises, particularly before the rainy season, can help prevent water accumulation that may saturate the charging station base or power cables. There should not be any standing water within a 2-meter radius of the charging station. Check for leaks in buildings and ensure proper drainage of sewer pipes during rainfall. After rain showers, examine basements, cable trenches, and tunnels for any accumulated water promptly draining it if necessary. Ensure sufficient ventilation when there is excessive moisture in equipment rooms.

Daily Management

Charging stations, transformer rooms, and charging rooms should be kept clean and hygienic, with cable trenches free of debris and all covers intact. Measures should be taken to prevent infestation by insects or rodents as well as theft. When entering or exiting transformer rooms, distribution rooms, or charging rooms, please remember to securely close doors and windows. Regularly inspect the sealing strips on protective nets to prevent accidents caused by small animals sneaking in. If there is any abnormality or failure in the operation of the equipment room air conditioning and cooling fans, timely maintenance or replacement should be carried out without delay.

Dangerous Goods

The entry of any flammable, explosive, corrosive, strongly electromagnetic, or radioactive materials that may pose a threat to the normal operation of the equipment is strictly prohibited at the charging station. Smoking inside the charging station is strictly prohibited as well. The use of electrical appliances unrelated to charging within the charging station is also strictly prohibited.

Core Area

Unauthorized personnel are not allowed to enter the monitoring room, charging room, distribution room, or charging area without permission. The computer used for monitoring should only be used for its intended purpose and it is prohibited to browse the internet using server devices (computers). Writing, modifying, or changing various software systems and device parameter settings on equipment in the monitoring room is strictly forbidden. Maintenance, addition/deletion/configuration changes of various software systems and addition/replacement of hardware devices must be carried out by professional manufacturers. Uninterruptible power supplies should be regularly inspected and maintained, and should not be used for any other purposes.

Communication and Emergency

When detecting obvious abnormalities in charging vehicles, it is important for charging station operators to inform customers and advise them to repair their vehicles. Unrelated personnel are strictly prohibited from plugging or unplugging the charging gun or touching any of the charging equipment. It is necessary for operators to regularly contact the power supply department proactively in order to stay updated on the operation of the power supply network. Additionally, maintaining diligent duty records, patrol records, and shift handover records is crucial. In case of emergencies, cutting off power promptly and accurately can help prevent accidents from escalating.

Charging Process

Preparation Before Charging

• After the charging pile is powered on and self-checked, the system enters the charging interface. The status indicator of the charging machine should be able to light up normally, and the display interface of the charging machine should be able to operate without any fault display. The cooling fan of the charging machine should run normally.
• When a vehicle enters the charging area, it should be parked in a position where the cable plug can reach. The car key should be removed and kept by a dedicated person, and all doors must be locked with low-voltage power switch turned off to ensure that during the charging process, there will not be anyone performing vehicle maintenance or any other operation unrelated to charging. 
• Charging operators should wear insulated gloves for their work, and when air humidity is high they also need to wear insulated shoes.
• Confirm that high-voltage manual quick breakers are connected properly.
• Check whether both sides of charger gun and socket are intact,tightened securely,dry,and dust-free.
• Check that there is no damage on charge cables before use.

Connecting Charging Gun

• Remove the charging gun from the fixed rack of the charging station, holding it with one hand while holding the charging cable with the other hand. Pull on the charging cable to move it, but avoid pulling on the charging gun.
• Apply even force to insert the charging gun into the vehicle’s charging socket and ensure that its locking latch engages with the socket groove. The mechanical button on the charging gun should pop up, ensuring full contact between the charger plug and vehicle socket. 

Charging

• Choose the charging mode to initiate the charging process, and the charger will perform a charging handshake before entering the monitoring interface for charging status.
• Once charging begins, ensure that all charging data is normal and monitor the operational status of the charger closely. If any interruptions or abnormalities occur, immediately stop the process and notify maintenance personnel for assistance; unauthorized intervention or judgment is strictly prohibited.
• In case of abnormal noises inside the charger, unusual current or voltage displays, strange odors or smoke generation within the machine, anomalous LCD screen displays, or anomalies in various signal indicator lights during operation, promptly cease charging and cut off power supply by switching off AC main switch to prevent further damage to components.
• If battery voltage rises rapidly when approaching saturation level during a charge cycle, immediately halt it and provide timely feedback to relevant technical personnel for their attention and resolution.
• No personnel is allowed to stay in the vehicle during the charging process. It is strictly prohibited to open the doors, start the vehicle’s power, move the charging equipment, or engage in any other activities.
