Study: EVs cannot succeed without developing parallel supercharging networks Electric vehicles cannot succeed without developing a nationwide network of fast-charging networks in parallel with the cars. Current EV business models are doomed unless manufacturers that have bet their futures on them, such as General Motors and VW, invest in or coordinate on a robust supercharger network. These are the observations in an in-depth study of the industry by management professors at the University of California, Davis, and Dartmouth College. The researchers say that that while large, traditional automakers have developed some exciting EVs, they have essentially ignored the charging station side of the equation. Meanwhile, Tesla worked both sides of the market by building a sufficiently wide network of high-speed charging stations before they sold too many cars. There are about 4,000 high-voltage super-fast charging stations in the US, and the majority of them are available only to Tesla vehicles.
