Through the project, Hitachi will utilise its accumulated EV charging technologies to develop and demonstrate next-generation high-power chargers.

The CHAdeMO Association has standardised the next-generation high power charging standard (ChaoJi), which is under joint development between Japan and China, as CHAdeMO3.0. Design requirements were issued last year. CHAdeMO 3.0 supports high output power of over 500 kW (maximum charging current: 600 A). It uses liquid cooling technology and relocates the lock mechanism to the inlet side to enable the connector to be compact and the charging cable compact and lighter. The design maintains backward compatibility with existing CHAdeMO 3.0 vehicle fast chargers (CHAdeMO, GB/T*1, CCS*2). These technical elements are essential to widely promote EVs with large battery capacity and fast charging infrastructure.

The project is planned to be implemented at Hitachi’s Omika Works with plans to open this demonstration site to domestic and foreign vehicle OEMs for two years from April 2023 through the CHAdeMO Association.
