EV batteries are getting cheaper and cheaper, encouraging OEMs to put more battery capacity in their vehicles. However, what is fast charging for 16-24kWh batteries, becomes not so fast when the battery size reaches 40, 60 or more kWh. To meet the expectations of the e-mobility stakeholders and drivers, CHAdeMO is working on high power charging. A new edition of CHAdeMO protocol enabling 200kW to 400kW charging was developed by the Association and its members, who are now preparing for 900kW.

While 200kW means a significant change of charging speed for EVs with high capacity batteries, it does not require a lot of changes in the protocol itself. The main changes concern the connector and not the charger body or charging specification.
