Electrify America, Volkswagen’s EV charging network unit, has more than 850 charging stations with about 4,000 chargers in the US and Canada. During the NACS transition, Electrify America will continue to offer the widely used CCS connector.

Tesla, meanwhile, has expanded beyond its connectors to include CCS at some of its US charging stations as the Biden administration seeks to provide billions in subsidies to expand charging networks.

The EV maker’s Superchargers account for about 60 percent of the total number of fast chargers in the United States, according to the US Department of Energy.

The companies’ decisions for NACS transition have shaken up the EV charging industry that is likely to be drifting towards the rival CCS connection, with the help of federal subsidies.

Separately, Polestar has signed an agreement with Tesla to make its charging network available to the customers of the Swedish electric vehicle maker in the United States and Canada.
