【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.

【Key words】electric vehicle；800V high voltage platform；opportunities；technical challenges

電動(dòng)汽車被認(rèn)為是解決能源危機(jī)和環(huán)境問(wèn)題的一種方法，而由于續(xù)航里程短和充電時(shí)間長(zhǎng)所造成的里程焦慮以及充電焦慮很大程度上制約了純電動(dòng)汽車的銷量，也限制了其對(duì)燃油車的替代。（剩余4363字）
