Nio

Nio builds premium electric vehicles in China. The company’s EVs feature swappable batteries that allow drivers to get back on the road minutes after pulling into battery-swap stations. It has signed partnership agreements with other carmakers, Zhejiang Geely and Changan Automobile, to build cars with the technology and expand the country’s network of swap stations. It operates two plants, both in Hefei, the capital of Anhui province.
