My taxi in Hebei ski country just pulled off for two-minute battery change by robot. A fresh battery lasts 150km in winter, says driver. He pays 45yuan ($7) for a fresh battery. Impressive system, all the more for being totally workaday, not exotic. Future here now for China EVs. pic.twitter.com/l8DkUtW2pA
