Charging heavy vehicles, such as trucks, requires more power, therefore a new MCS (Megawatt Charging System) standard was designed with a voltage of up to 1250 V DC and a current of up to 3 kA. This standard introduces a new connector with 7 outputs (2 DC, PE, CP, PP and 2 communication) and the possibility of active cooling of the wires. Standardization is covered by IEC 63379 / J3271, communication takes place according to ISO 15118. The design supports two-way energy flow, the vehicle can serve as an energy store for another device, building, network (Vehicle-to-grid - V2G) or another vehicle (Vehicle-to-vehicle - V2V) ). standardization is covered by the CharIN association.
Currently, there are three current levels considered at a voltage of 1250 V DC:
Level 1: +350A ... 437 kW
Level 2: +1000A ... 1.25 MW
Level 3: 3000A ... 3.75 MW
Charging a 100 kWh battery would take 14 minutes at Level 1, 5 minutes at Level 2 and less than two minutes at Level 3.
With this type of charging, the support of means other than vehicles is also considered. For example, the company Lilium, which develops electric flying vehicles for the transportation of people, announced that it will use the Megawatt Charging Standard connector on its aircraft - a VTOL taxi.
