Ultra-fast charging (>1 MW)

Multiple charging standards are currently being developed for charging medium- and heavy-duty vehicles at power rates of greater than 1 MW. Technical specifications for ultra-fast charging are under development. In China, co-developers China Electricity Council and CHAdeMO's 'ultra ChaoJi' are developing a charging standard for heavy-duty electric vehicles for up to several megawatts. In Europe and the United States, specifications for the CharIN Megawatt Charging System (MCS), with a potential maximum power of 4.5 MW, are under development by the International Organization for Standardization (ISO) and other organisations. The final MCS specifications, which will be needed for commercial roll-out of medium- and heavy-duty electric vehicles, are expected for 2024.
Ensuring maximum possible convergence of charging standards and interoperability for heavy-duty EVs will be needed to avoid the cost, inefficiency, and challenges for vehicle importers and international operators that would be created by manufacturers following divergent paths.
