Is It Normal for New Energy Electric Vehicle Cables to Heat Up?

The heating problem of new energy electric vehicle cables


Slight heating of new energy electric vehicle cables is normal, because the transformer will be constantly passing through voltage and current during the working process of the charger. For high-intensity currents, it is easy to increase the temperature of the transformer, so the charging line will also heat up. If it is a hot summer, the temperature may have some impact on the degree of heat generated by the charging line.


If the car owner finds that the electric vehicle cable of the new energy electric car is overheating and has reached a temperate temperature during use, consider that this is caused by factors such as long charging time, large current and voltage, and malfunction of the charger's heat sink. It is recommended to unplug the power supply in time and try again after the charger is completely cooled. If the overheating is still severe, it is recommended to replace the brand new charger.


When purchasing a new energy vehicle charger, you must choose a regular and original charger, because poor quality chargers can easily cause electric vehicle cables to generate heat. At the same time, when charging, it is necessary to avoid direct sunlight and finally charge in a shady and sun-shaded position.


How to charge electric cars?


For pure electric vehicle charging, the vehicle must be turned off first, and then the DC charging port in front of the engine compartment is opened. Remove the charging gun on the charging pile, and then insert it into the car's charging port. Next, select the charging mode on the charging pile, you can choose to charge with a charging card, swipe the card to select the corresponding payment mode, and click OK. It is recommended to select the automatic full charge mode, and then see that the charging connector is correctly connected on the screen, swipe the card to confirm the charging.


  • Fast charging, which mainly uses non-vehicle-mounted charging machines, and then charges the vehicle's battery through high-current methods. This method can allow the car battery to reach about 80% in a short period of time, and it takes about 1 hour to fully charge it.

  • Slow charging, which represents the conventional electric vehicle charging, usually used for home wall-mounted charging piles or vehicle-mounted charging machines. The charging power and current of slow charging are relatively small, so it takes about 6 to 8 hours to fully charge.

  • Wireless charging, which uses wireless charging source panels embedded in roads and parking spaces without wires or cables. Using this method to charge is safe and fast, but it is not widely used in the short term.

  • Battery swapping, which means using the method of replacing power batteries to replenish energy to the battery. When the car's power is quickly depleted, use a fully charged battery to replace the depleted battery and send it to the battery exchange station for charging.
