Cable with CHAdeMO-specification-based Quick Charge Connector for EV Applications

Chargeable by simple operation

 

The recent growth of public interest in electric vehicles (EVs) has encouraged the installation of quick chargers. Sumitomo Electric has developed a cable fitted with a CHAdeMO-specification-based quick charge connector that plays an important role in supplying electric power to EVs from quick chargers. Comprising a lightweight aluminum alloy connector body, this easy-bend rubber sheathed cable provides excellent operability. A workable prototype of the cable was unveiled to the public at the 2nd EV & HEV Drive System Technology Expo, held in January 2011. At the Expo, the cable’s design and operability received favorable comments from the visitors.

Sumitomo Electric is currently establishing a production/marketing system with the aim of bringing the cable to market as early as possible.
