High-power electric vehicle charging cable is a key component connecting charging piles and electric vehicles. The selection of its performance is crucial to the safety and efficiency of the charging process. When selecting high-power electric vehicle charging cables, you need to pay attention to the following performance aspects:

Good electrical conductivity: Electric vehicle charging cables should have good electrical conductivity to reduce energy loss and resistance. High-quality conductive materials and designs can reduce the resistance of the cable and improve energy transfer efficiency, thereby shortening charging time and reducing energy waste.

High temperature resistance: High-power electric vehicle charging cables have high current and voltage during high-power charging, which will generate higher temperatures, so they need to have good high-temperature resistance. Cable materials should be able to withstand high temperature environments, maintain the structural integrity and performance stability of the cable, and avoid cable damage or safety hazards caused by excessive temperature.

Good wear resistance and durability: Electric vehicle charging cables are frequently plugged and unplugged, bent, or dragged on the ground in daily use. The outer material of the cable needs to have good wear resistance and durability to ensure that the cable can be used for a long time. It is not easy to be damaged or broken.

Environmental adaptability: Electric vehicle charging cables are used in charging places under various circumstances. Excellent environmental adaptability extends the service life of the cable and ensures the safety of electricity, such as waterproof, moisture-proof, acid and alkali resistance, etc. to prevent moisture from entering the cable. Internal short circuit or damage. Cable design and material selection are key to ensuring cables function properly in a variety of weather conditions.

Anti-interference ability: High-power electric vehicle charging cables should have good anti-interference ability to reduce the impact of external electromagnetic interference on the charging process. Shielding technology and high-quality cable design can effectively reduce electromagnetic interference and improve the stability and reliability of the charging process.

Impact: When electric vehicles are charged quickly with high power, the charging cable will withstand large currents and generate a large amount of heat, causing the cable to heat up due to heat accumulation, shortening the service life of the cable, and even causing physical damage and accidents such as leakage. The safety of standard cables is reliable, but if the charging power and charging current are further increased, the temperature of the cable insulation layer will exceed the safety limit, making it impossible to work safely, and additional heat dissipation measures will be required. .
