The ROEV Association, announced at the Los Angeles International Auto Show, is a collaborative project between BMW and Nissan with CarCharging/Blink, ChargePoint and NRG EVgo, accounting for 91% of the public charging points in the U.S. (17,500 units).

Its goal is to make life easier for drivers, who currently have to carry a number of access cards to use the various charging networks in the U.S., by adopting standards which will enable units to share information, in turn meaning a single membership will offer open access across multiple networks.

ROEV said other stakeholders have already signed up, including Audi, Honda, Efacec, Portland General Electric, SemaConnect, and BTC Power, and other members are being invited to join.

Simon Lonsdale, chair of the board of ROEV, said: "Driving an EV will be easier thanks to ROEV. The EV driver's ability to find, and charge at, any member public station, using an EV charging network account of their choice, is paramount to a simple driving and charging experience.”
