The Globe and Mail reports in its Thursday edition that China's electric vehicle industry leaders are calling for stronger global co-operation and standardization in policy to ease the technological transition. A Reuters dispatch to The Globe says that Wan Gang, a key figure in leading China's development of electric vehicles, said efficient batteries, better EV architectures and intelligent driving systems were the three key technologies required to boost EV uptake. Differences in policy, industrial foundations and the level of technological development were leading to a growing disparity in EV growth across global regions, said Robin Zeng, chairman of the world's largest battery maker CATL. The executives were speaking at the World New Energy Vehicle Congress in Munich, happening for the first time outside China in a symbol of Chinese EV makers' ambitions for expansion. "We want to invite partners from Germany to join BYD to promote green transport," BYD chairman Wang Chuanfu said. Chinese EV executives from companies including Xpeng, Leapmotor and SAIC have called in recent days for more partnerships with German carmakers, expressing admiration for the innovations on display at Munich's IAA conference.
