Nissan and EVgo have revealed a plan to connect Boston and Washington DC via nine electric-vehicle DC fast-charge sites.

The automaker said the plan would deliver a “robust charging infrastructure along I-95” providing EV owners peace of mind when driving along the route. The charging route should be available this autumn.

The so called I-95 Fast Charge ARC is already under construction. Covering the 500 mile span between the two cities, the nine sites and 50 charging stations will have a capability of charging four or more EVs simultaneously at a power output of 50kW. The charging sites have been designed with future advances in EV technologies in mind and have been pre-wired for a high-power charging power output of up to 150kW with simple upgrades once such technology is available to consumers.

Each station will feature both CHAdeMO and Combined Charging System (CCS) DC fast-charging outlets as a part of Nissan’s inclusive Infrastructure for All initiative. When plugged into a DC fast charger, a Leaf can be charged up to 80% in approximately 30 minutes.

“Regardless of range capability, a convenient fast-charge infrastructure along high traffic routes is imperative in the mass-adoption of electric vehicles,” said JeSean Hopkins, senior manager, EV infrastructure strategy & business development, Nissan North America. “This element of the EV equation is seemingly overlooked by others, but we’re all-in. Following a similar project in California, this is our second ‘corridor’ project in the US and completion is expected in time for the launch of the [redesigned] Leaf.”
