Megawatt Charging System
Also called: MCS The Megawatt Charging System, or MCS, is a high-power DC charging system developed for heavy-duty electric vehicles using the MCS coupler. It is aimed at vehicles that need much higher charging power than conventional passenger-car charging systems. IEC TS 63379:2026 specifies the MCS vehicle connector, vehicle inlet and cable assembly. IEC 61851-23-3:2026 covers the associated DC EV supply equipment. MCS charging also uses digital communication between the EV and EVSE. IEC 61851-23-3 points to ISO 15118-10 and ISO 15118-20 for communication used to control energy transfer.
