Fast Charging Technology for Electric Vehicles

With the advent of the new energy era, the innovation of the automobile industry can be said to be earth-shaking. More and more fossil energy is being replaced by clean energy. At present, the fastest developing new energy vehicles in the market are mainly electric vehicles. The biggest advantage of such vehicles is low maintenance cost in addition to environmental protection. In China, the government is actively introducing electric vehicles and has also launched many policies to stimulate sales of new energy vehicles in 2019. In March 2022, China's BYD company announced that it would stop the production of fuel cars, becoming the first traditional auto company in the world. German automaker Audi also announced that it will not develop or launch a fuel car in 2026. Fast charging is at the heart of the power supply for electric vehicles. This paper introduces the chemical concerns and electrical design for the fast charging technology.
