50kW Quick Charger for EVs

Nichicon Corporation announces the release of the world’s smallest and lightest* quick charger for EVs (Electric Vehicles). This 50-kW-capacity model is certified for the CHAdeMO system and expands the company’s lineup of quick chargers for EVs. By utilizing its technology for OBCs (on board chargers) for EVs and standardizing the main components, Nichicon has developed a 50-kW quick charger that is approximately 60% smaller and 50% lighter than its current model.


With issues like global warming raising the environmental awareness of people around the world, countries are working in earnest to reduce their carbon emissions. Nichicon has been supplying OBCs (OBC with DC/DC converter) for the Mitsubishi EV (i-MiEV) and the Nissan EV (LEAF) since the release of these two electric vehicles. Besides OBCs, Nichicon has also been helping spread the use of EVs by developing and mass-producing quick charging systems for vehicles.

This 50-kW model expands Nichicon's lineup of high-capacity quick chargers. Like the world's smallest and lightest 20-kW and 30-kW quick chargers for EVs, which Nichicon released on August 24, 2011, this model was made to be an ultra-compact quick charger. Nichicon has achieved an amazingly thin 50-kW EV quick charger: this latest model measures the same width and height (350 mm x 1565 mm) as the 20-kW and 30-kW models.

The most remarkable point of this newly developed quick charger is that it occupies approximately 60% less space and weighs about 50% less than the current model. This saves the customer cost and effort in installing this system. And the quick charger's thin profile makes possible a greater range of installation locations. Nichicon has also made the most of its technological expertise in OBCs to develop a modularized charger that boasts high reliability and high efficiency, features that will help hasten the spread of the charging infrastructure for EVs.
