Aker Wade Power Technologies has entered into a licensing agreement with Tokyo Electric Power Company (TEPCO) to manufacture and market Level III DC fast chargers for electric vehicles. The chargers will incorporate TEPCO’s patented technology and be capable of charging vehicles such as the Nissan Leaf, Mitsubishi i-MiEV and Plug-In Stella by Subaru within less than half an hour. Aker Wade is the first US manufacturer that has concluded a license agreement to use this technology.
Aker Wade is also joining CHΛdeMO (stands for Charge and Move), an association formed by Nissan, Mitsubishi, Subaru and TEPCO that will start this March to promote a common use quick charger.

The association is being founded to give drivers a sense of assurance that chargers of member manufacturers are fully compatible with electric vehicles of member OEMs.
Under TEPCO’s scheme, only the communication protocol and the connector are standard; the main circuits and component designs are dependent upon the EVSE (electric vehicle supply equipment) makers.
TEPCO has been a pioneer in the implementation of electric vehicles. Since 2006 it has tested more than 300 battery powered cars in the greater Tokyo area. From this experience it became convinced that fast chargers were the answer to overcome consumers concerns about the electric vehicle’s limited range.
When we deployed fast chargers the vehicles were driven over 50 percent more. Drivers felt comfortable and used the full range of the vehicle.—Takafumi Anegawa, group manager of TEPCO’s Mobility Technology Group at their Yokohama R&D Center

Aker Wade Power Technologies designs and manufactures advanced fast charging systems for electric vehicles and industrial forklifts. Aker Wade is collaborating with battery companies, infrastructure suppliers and EV manufacturers to deliver advanced Level III fast charging solutions for the future generation of battery electric vehicles.
Earlier this week, Aker Wade and Coulomb Technologies agreed to deploy Level III networked fast charging stations for electric vehicles worldwide. The Level III fast charging stations will be co-developed, distributed, marketed and supported by both companies, and designed in accordance with the TEPCO Level III specifications. (Earlier post.)
