Development of high-power charging cables for electric vehicles

China [CN]

With the green and low-carbon development of transportation and the promotion of comprehensive electrification of vehicles in the public sector, the country has vigorously promoted new energy vehicles and improved charging piles, battery swap stations and other new energy vehicle charging supporting facilities. In addition, in the mainstream charging background of high-power charging, in order to achieve high-current charging and ensure safety, the charging cables must be continuously thickened and thickened, and the cost is also increasing. The emergence and use of high-power liquid-cooled charging cables can not only reduce the thermal damage caused by high-power charging to charging guns, charging cables, and charging piles, but also reduce the weight of cables and insulation layers, which is very suitable for high-power charging of electric vehicles.

The main technical point of liquid-cooled charging cables is the use of liquid-cooled charging technology. By adding cooling pipes to the charging guns, charging piles, and charging cable loops, and adding coolant pipes inside the cables, it can be compatible with two different requirements of high voltage 400V and 800V, and can also ensure low temperature rise of the charging interface.

Against the background of increasing global climate change and resource and environmental pressures, electric vehicles, as representatives of green travel, are changing our travel methods at an unprecedented speed. In this green revolution, high-power charging cables, as a key component of electric vehicle charging technology, are becoming an important force in promoting the sustainable development of the electric vehicle industry and even the entire society with their excellent performance and continuous technological innovation.

The widespread application of high-power charging cables has not only promoted the rapid development of the electric vehicle industry, but also laid a solid foundation for building a future energy ecosystem. It enables electric vehicles to access the power grid more conveniently and achieve deep integration with renewable energy. With the support of smart grids, electric vehicles can be used as distributed energy storage units to charge when the grid load is low and discharge at peak times, providing flexible adjustment capabilities for the grid and helping to achieve efficient energy utilization and low carbon emissions.

The social development power of high-power charging cables is also reflected in their positive contributions to environmental protection and economic and social development. On the one hand, by reducing the consumption of fossil fuels and reducing carbon emissions, high-power charging cables have made important contributions to addressing global climate change and protecting the environment. On the other hand, with the continuous growth of the electric vehicle industry and the improvement of charging infrastructure, the widespread application of high-power charging cables will also drive the development of related industrial chains, create more employment opportunities and economic benefits, and promote the sustainable development of the economy and society.

In summary, as an important part of the new engine of green travel, high-power charging cables for electric vehicles are leading the electric vehicle industry and the entire society towards a greener, low-carbon and sustainable future with their excellent performance and continuous technological innovation. We have reason to believe that in the near future, high-power charging cables will become an important cornerstone for building the future energy ecosystem and contribute more to the sustainable development of mankind.
