How can the electric vehicle industry leverage the high conductivity of copper-clad steel wires to improve charging and energy transfer efficiency?

The electric vehicle (EV) industry has significantly improved the efficiency of charging and energy transmission by leveraging the high conductivity of copper-clad steel wires (CCS wires). Copper-clad steel wire combines the excellent conductivity of copper with the strength of steel, providing multiple advantages for electric vehicle charging systems, specifically in the following aspects:

Improve charging efficiency: The copper layer of copper-clad steel wire provides extremely low resistance, thereby reducing energy loss during transmission, especially in high-power charging systems. Fast charging of electric vehicles requires a large amount of current transmission. The high conductivity of copper-clad steel wires helps improve current transmission efficiency, reduce heat generation, and ensure a more efficient charging process.

Reduce costs: Although pure copper materials have better electrical conductivity, their costs are higher. Copper-clad steel wire maintains excellent electrical conductivity while greatly reducing material costs by using a steel core and covering it with a copper layer. This cost advantage is particularly prominent in the construction of large-scale electric vehicle charging infrastructure, making the construction of charging piles and battery systems more cost-effective.

Enhanced durability and safety: The charging system of electric vehicles usually requires long-term exposure to various environmental conditions. The steel core of the copper-clad steel wire enhances its mechanical strength and can withstand higher tensile force and external pressure, extending the use life. In addition, the copper layer of the copper-clad steel wire also provides good corrosion resistance, especially in humid and corrosive environments, improving the long-term stability of the system.

Support higher power requirements: With the advancement of electric vehicle technology, charging power requirements are also constantly increasing. Copper-clad steel wires can carry larger current loads to meet the needs of fast charging technology. Its high conductivity and strength make copper-clad steel wire an ideal transmission medium in high-power electric vehicle charging facilities.
