Even a small spark generated during the connection or disconnection of the charging equipment may ignite these substances, leading to a fire or explosion. ለምሳሌ, in a parking lot with a charging station, if there are gasoline – powered vehicles parked nearby with fuel leaks, it creates a highly dangerous situation. A tiny spark from the charging operation could potentially trigger a large – scale fire, endangering the safety of people and property in the vicinity. Therefore, it is necessary to ensure that the charging area is free from any such hazards. If any flammable or explosive materials are detected, move the vehicle to a safer location or remove the hazardous substances before proceeding with charging.

2. Inspection of the Charging Pile

The next step is to check the condition of the charging pile itself. አንደኛ, carefully observe the display screen of the charging pile. If the screen is functioning properly, closely look for any error messages or fault indicators. Modern charging piles are equipped with advanced monitoring systems that can detect various malfunctions. These malfunctions can range from power supply issues, such as voltage instability or power outages, to communication problems between the charging pile and the vehicle or the central management system, and even internal component failures. Once a fault occurs, it is usually clearly displayed on the screen. ለምሳሌ, if the charging pile’s power module fails, the screen may show an error code related to power supply, like “Power Module Error: 001”. In such cases, it is not advisable to use the faulty charging pile. Instead, immediately contact the relevant maintenance personnel to repair the problem. Even if the screen appears normal, it is still a good practice to visually inspect the exterior of the charging pile for any signs of damage, such as cracks, loose parts, or exposed wires. A cracked housing may expose the internal electrical components to the outside environment, increasing the risk of short – circuits and electric shock.

Determining whether the charging gun is compatible with the vehicle is another crucial aspect. For older – generation vehicles that follow the old national standard, there is generally less concern as the new national standard is designed to be backward – compatible. In most cases, these vehicles can be charged using new – standard charging guns without issues. ቢሆንም, for new – generation vehicles that adhere to the new national standard, which is now the majority, special attention should be paid to the charging gun. New – standard charging guns are often equipped with electronic locks. When checking compatibility, not only should the physical connection between the gun and the vehicle’s charging port be verified, but also the proper functioning of the electronic lock mechanism. Insert the charging gun into the vehicle’s charging port and check if the electronic lock engages smoothly. If the lock fails to work properly, it may indicate a compatibility issue or a problem with the charging gun.

ከዚህም በላይ, it is vital to avoid using charging guns with dirty gun cores. A dirty gun core can cause a poor electrical connection, which may lead to charging short – circuits. A short – circuit during charging can not only damage the vehicle’s charging port but also pose a risk of electrical shock and fire. ለምሳሌ, if there is dirt or moisture on the gun core, it can create a conductive path that bypasses the normal charging circuit, resulting in abnormal current flow. This abnormal current can cause overheating at the charging port, melting the plastic components and potentially starting a fire. In addition, the sudden short – circuit current can also damage the vehicle’s battery management system and other electrical components, leading to costly repairs.

4. Reading the Charging Process Instructions

Each manufacturer’s charging pile may have a slightly different charging process. Therefore, before charging, it is essential to carefully read the charging process instructions provided on the charging pile or in the associated documentation. These instructions typically include details on how to start the charging process, how to monitor the progress, and how to end the charging safely. Ignoring these instructions can lead to charging failures. ለምሳሌ, some charging piles require users to insert the charging card first and then connect the charging gun, while others may have a different sequence. Some charging piles may also have specific requirements for the way to input charging parameters, such as the charging amount or the charging time limit. By following the correct charging process, users can ensure that the charging process starts smoothly and that the vehicle is charged properly.

When connecting the charging gun to the vehicle, make sure to insert it firmly into the charging socket. A loose connection can cause intermittent charging or even charging failures.

In rainy or humid environments, the risk of electric shock from a damaged cable is even higher. Water can conduct electricity, and if it comes into contact with the exposed wires, it can create a dangerous situation for anyone in the vicinity.

3. Secure Connection between the Plug and the Socket

During charging, ensure that the charging plug is fully inserted into the socket. A loose connection can cause arcing, overheating, and abnormal charging. Arcing occurs when there is a gap between the plug and the socket, and electricity jumps across the gap. This can generate heat and potentially damage the charging equipment and the vehicle’s charging port. Overheating due to a loose connection can also lead to a fire. ለምሳሌ, if the plug is not inserted fully, the resistance at the connection point increases. According to Ohm’s Law, when the resistance increases and the current remains constant, the power dissipated at the connection point (P = I²R) will increase, causing the area to heat up. If the heat cannot be dissipated effectively, it can melt the plastic components of the plug and socket and potentially start a fire.

4. Professional Installation and Maintenance

Charging piles should be installed and maintained by professional personnel. If there are any problems with the charging pile, do not attempt to fix them yourself.
