Lately, as the capacity of the batteries installed in electric vehicles has been increasing, there has been a need for faster charging equipment that can accommodate more power. To satisfy this need, the Company has developed SEVD™-11U, a new quick-charger connector assembly that boasts the largest capacity in CHAdeMO-specific connectors, as a new line of the SEVD™ series. SEVD™-11U has obtained UL certification,*1the North American safety standard.

The Company is planning to add CE*2-certified models that meet EU safety standards and domestic models to this lineup.
