A new partnership between ChargePoint and Electrify America will allow users of each electric-vehicle charging network to use the other network with no additional charges, the operators have announced.

The "roaming" agreement, which may help users think about the agreement in a similar way as cellular networks, is expected to help accelerate adoption of plug-in vehicles, because it overcomes a proprietary-network hurdle.

"This roaming agreement further accelerates the seamless integration of individual EV fueling networks and brings us even closer to the day when the movement of all goods and people will be powered by electricity," said Pasquale Romano, ChargePoint's president and CEO. "Partnerships like this make transitioning to electric drive easier than continuing to use fossil fuels."

There will be more than 30,000 individual charge points connected by the two networks, including Level 2 AC and DC fast charging (CCS or CHAdeMo). ChargePoint claims to be the largest charging network in the world with 66,000 locations. Electrify America has pledged to have 2,000 charging points at 484 locations in the U.S. by July 1.

ChargePoint has also made an agreement with WEX Inc. to provide seamless charging payments for commercial and government fleets.
