The important impact of electric vehicle charging cables on fast charging

Date:2024/3/14 8:16:52

With the rapid development of electric vehicles and the increase of charging demand, charging cable, as an important part of electric vehicle charging system, has an important impact on charging speed and charging efficiency. In this paper, we will discuss the impact of electric vehicle charging cables on fast charging and introduce related optimisation strategies and technologies.

1. Transmission capacity of charging cable: The transmission capacity of charging cable directly affects the charging speed of fast charging. Fast charging usually adopts DC charging mode, which requires high charging power. Therefore, charging cables need to have sufficient conductivity to stably transmit high power. OMG' focuses on providing electric vehicle charging cable solutions, and selects high-quality charging cable materials and appropriate cross-section area of wires according to the actual demand, which can reduce the resistance of the cable, improve the charging efficiency and realise fast charging.

2. Durability of charging cables: During fast charging, charging cables are subject to high currents and frequent plugging and unplugging operations, so their durability is critical. Cables with poor durability are prone to damage or overheating, thus affecting charging effect and safety. In order to improve the durability of charging cables, OMG' puts the use of high-quality materials and structural design into production, increasing the tensile strength and abrasion resistance of the cables, as well as paying attention to the correct operation and maintenance in the process of use.

3. Temperature management: During fast charging, the charging cable and connector may generate a certain amount of heat, which requires effective temperature management. Excessive temperature will affect the conductivity and safety of the charging cable, and even lead to potential safety hazards. Therefore, charging cables should have good heat dissipation performance, and OMG' improves the temperature management capability by optimising the heat dissipation structure and increasing heat dissipation materials. Our liquid-cooled charging cables utilise liquid-cooling technology to incorporate a liquid-cooling circulation system inside the cable, and a structural form that allows the cooling system and charging system to co-exist and function together through a sealed circulation connection inside the charging gun. This allows the cable to maintain a low and constant temperature during the charging process, overcoming the thermal damage caused by heat generation to the charging gun, charging cable and charging pile, thus increasing the DC charging current.

4. Safety considerations: charging cable as an important link in the transmission of electricity, safety is a factor that can not be ignored. OMG's design and manufacture of charging cables, follow the relevant safety standards and norms, cables are in line with the European standard, the American standard, the Japanese standard, the Chinese standard and other standards in the industry, to ensure that the cable's insulation and voltage resistance, to prevent electric shocks and fires and other safety issues occurring.
