On the 19th, Wang Chuanfu, chairman and President of BYD group, said that the electrification of vehicles has brought great changes that have not been seen in a century, and the industrial supply chain system has been reconstructed. "In the field of semiconductors, the demand for semiconductors by electric vehicles is 5-10 times higher than that of traditional vehicles. However, due to the 'lack of core', about 7 million electric vehicles are not produced in the world. Electric vehicles are the first half, smart vehicles are the second half, and smart vehicles have greater demand for semiconductors."
