From late 2014 onwards, RFID access cards and smartphone apps from either company will allow access to the CarCharging Blink network and GE’s WattStation EV charging points located throughout the United States.

The deal is aimed at allowing electric vehicle owners easier use of a growing charging infrastructure operated by both companies. CarCharging acquired four businesses last year, including ECOtality's 12,560-strong Blink charging point network after the company went into administration in September, while GE has a partnership with PayPal to simplify payment for access to its network.

Michael D. Farkas, chief executive officer of CarCharging, said: ‘CarCharging is committed to working with all EV charging manufacturers on interoperability, and we are proud to work with GE on a solution that provides drivers with easier access to both Blink and GE EV charging stations.’

Seth Cutler, lead product manager, EV infrastructure and software, GE's Industrial Solutions business, added: ‘GE believes that interoperability across EV charging hardware should enable greater choices for equipment owners and greater mobility for EV owners. By working with CarCharging and their Blink Network, we are opening new access and payment channels for the entire EV industry.’
