With the rapid development and popularization of electric vehicles, charging technology is also advancing. However, prolonged high-power charging can lead to the problem of overheating of the charging cable, which brings certain safety risks to the charging process. In order to solve this problem, the following methods can be taken:

1. Optimize cable design: Improve the structure and materials of the charging cable to enhance its heat dissipation performance and high temperature resistance. For example, materials with better thermal conductivity are used as the outer layer of the cable to increase the heat dissipation area and effectively reduce the cable temperature.

2. Introduction of liquid-cooled technology: Liquid-cooled charging technology is an innovative solution to achieve active cooling of the cable by introducing a cooling liquid into the charging cable. Liquid-cooled charging technology works by flowing a cooling liquid through the internal channels of the charging cable, absorbing the heat generated by the cable and then removing it. Typically, the cooling liquid is circulated through a recirculation system to ensure that the charging cable remains within the appropriate temperature range at all times.

By lowering the temperature of the charging cable, liquid-cooled charging technology can effectively prevent safety issues caused by overheating of the cable, such as cable damage and fire. This is essential to ensure the safety of the charging process. And excessive temperature can cause damage to the material and structure of the charging cable and shorten its service life. The application of liquid-cooled charging technology can realize efficient heat dissipation of the cable, reduce the aging and damage of materials, and thus extend the life of the cable. In addition, liquid-cooled charging cables can also reduce energy loss, improve charging efficiency and shorten charging time. At the same time, with the rapid development of electric vehicles, the charging market has an increasing demand for charging power. The safety of liquid-cooled charging cables and the reliability of fast charging make them adapt to the demand of high power charging and are widely used in fast charging piles.

3. Control charging power: Reasonable control of charging power to avoid long time high power charging and reduce the risk of cable overheating. The power can be adjusted by intelligent charging equipment or charging pile, which automatically adjusts the charging power according to the battery status and ambient temperature and other factors, keeping it within the safety range.

4. Regular inspection and maintenance: Regularly inspect and maintain the charging cable to ensure that the cable is well connected, the insulation is intact, and to clean up the debris and dust around the cable to maintain good heat dissipation.

5. Provide charging protection function: the charging equipment can be equipped with overheating protection function, which automatically stops charging or reduces the charging power when the temperature of the cable exceeds the safety range, in order to protect the safety of the cable and the charging equipment.

Solving the problem of overheating of charging cables requires comprehensive consideration of a number of factors. By taking appropriate measures, the temperature of the charging cable can be effectively reduced to ensure the safety and efficiency of the charging process.OMG' is committed to become the world's first-class new energy charging application technology provider, and after nearly three decades of steady development has already had a professional technical team and R&D experience.
