While U.S. automakers like Tesla are making gains in China’s EV market, the Shenzhen-based BYD Co. Ltd. is becoming a domestic power player in its own right. Under CEO Wang Chuanfu, the company sold almost 600,000 all-electric and plug-in hybrid vehicles in China—the world’s largest auto market—last year, a 232% annual increase. BYD’s EVs can also be found everywhere from Brazil to Australia. The company, backed by Warren Buffett’s Berkshire Hathaway, moreover provides a range of other environmentally friendly solutions in more than 50 countries and regions, from electric buses, forklifts, and sanitation vehicles to rail systems and batteries.
