China is surging ahead in electric vehicle sales and infrastructure. There are several competing options in the passenger car realm. One I have been watching is NIO. Like Tesla, they are not only making a variety of EVs, they are also providing great charging, or in this case, battery swapping options. Nissan and Renault attempt to launch this concept many years ago, but it never took off. Shanghai-based NIO appears to have refined it into a slick and quick system.
