【Abstract】In order to solve the problems of short range and long charging time of electric vehicles，major car manufacturers have successively launched fast charging solutions with voltages of 800V or even higher. The significant increase in charging rate and the use of higher voltage platforms also place higher demands on the high-voltage components of electric vehicles. This article briefly analyzes the current development status of the 800V high-voltage platform，as well as the technical problems brought by the implementation of the 800V high-voltage platform to automotive high-voltage components from a technical perspective.
