The Siemens SICHARGE Megawatt Charging System used in the test is based on the company’s existing SICHARGE portfolio, featuring a customised MCS dispenser. The successful test involved a pilot project that integrated the prototype MCS charging station from Siemens with a long-haul prototype battery electric long-haul truck.

The development of megawatt charging systems is seen as instrumental in driving the uptake of Battery electric trucks. With advancements in battery and charger technology, there is a growing demand for zero-emission transportation solutions, particularly in long-distance haulage. The introduction of the MCS, in combination with the current Combined Charging System (CCS), is poised to bring significant benefits to heavy-duty electrification.

The MCS comprises multiple SICHARGE UC150 power cabinets, a switching matrix, and a customised MCS dispenser. This system allows for rapid charging, with batteries commonly used in trucks able to reach 20 to 80 percent charge in about 30 minutes at a suitable charging station with an output of around one megawatt.

“Especially in long-distance transport, electric trucks and coaches will need fast MCS during the legally prescribed driving time break,” explained Markus Mildner, CEO eMobility, Siemens Smart Infrastructure. ”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 and underlines our ambition to actively make transport more sustainable.”
