Electric vehicle charging networks must be well connected to meet the surging demand for power around the world, according to a new report.

A new Navigant Research study says that communications technologies like RFID, Wi-Fi, ZigBee, Ethernet, cellular systems, and advanced metering infrastructure (AMI) are among the key reasons electric vehicle charging installations are able to proliferate around the world.

Public charging stations require the right communications capabilities to ensure that consumers are given access to charging power and the ability to pay. Even if the charging is free, the charging station must be able to communicate consumption data to the site owner or network operator, Navigant Research says.

Navigant says that the growing base of EVs and government efforts to encourage their spread will support millions of connected charging stations. These will include public charging stations along with installations by private fleets and at residential and workplace sites. Connectivity will enable remote control of the chargers, as could potentially enable utility-driven demand response (DR) capabilities.

Fully connected charging networks are still several years away but it will take off, according to the report. Global communications equipment and services associated with EV charging networks should generate revenue of just over $62.8 million in 2015 and expand eleven times to more than $709.7 million in 2024.
