> Interoperability of EV charging infrastructure. The requirements relating to interoperability similarly address less visible standardization along the national EV charging network. The FHWA is working to establish a seamless national network of EV charging infrastructure that can communicate and operate on the same software platforms from one State to another. The FHWA establishes interoperability requirements through this final rule for charger-to-EV communication, charger-to-charger network communication, and charging network-to-charging network communication to ensure that chargers are capable of the communication necessary to perform smart charge management and Plug and Charge.
