As the Megawatt Charging System (MCS), a new charging standard for heavy-duty EVs, enters the final stages of standardization, automakers and EVSE manufacturers are busily putting the new system through its paces. Commercial implementations of MCS, which industry experts are calling a game-changer for electric trucks, are expected to begin later this year.

The latest testing milestone was announced by Siemens Smart Infrastructure, which completed its first successful one-megawatt charge, in a pilot using a prototype Siemens MCS charging station and “a long-haul prototype eTruck from a well-established OEM.”

Siemens has introduced a prototype of the SICHARGE Megawatt Charging System, which consists of multiple SICHARGE UC150 power cabinets, a switching matrix and a customized MCS dispenser. The switching matrix bundles the output power of the charging stations and, depending on requirements, directs power to the MCS dispenser. Siemens says an output of around one MW could enable a typical e-truck battery to be charged from 20 to 80 percent in about 30 minutes.

Markus Mildner, CEO eMobility, Siemens Smart Infrastructure: “Especially in long-distance transport, electric trucks and coaches will need fast MCS during the legally prescribed driving time break. To ensure nationwide distribution of this, various requirements must be met including on the governmental side. However, the successful test brings us a big step forward on the technology side.”
