JFE Engineering has apparently made significant progress on its super-rapid charging system and claims that it will be ready for field tests before the end of the year. In addition, the company claims that it will be ready for production as soon as EVs supporting the rapid charging standard become available. The system utilizes 500-600 amps of current, significantly more than the CHAdeMO systems, which of course means that the Nissan Leaf and Mitsubishi i-MiEV are not currently compatible with the super-rapid standard. Of course, there's still concern over battery degradation from the rapid charging system, but JFE remains confident that batteries can be designed to withstand the additional strain. We'll update you again as soon as the super-rapid charging system swings into action. Hat tip to Larz!
