Thanks to generous incentives and the size of the market, China has quickly become the largest market for plug-in electric cars.

According to the U.S. DOE’s Office of Energy Efficiency & Renewable Energy, sales of plug-in vehicles in China amounted around 550,000 last year, compared to nearly 200,000 in the U.S.

Also, in terms of market share, China has an edge over the U.S. - some 2.3% of new vehicles were plug-ins in 2017, while the U.S. onlyreached 1.1%.
