The Megawatt Charging System (MCS) is a charging connector under development for large battery electric vehicles. The connector will be rated for charging at a maximum rate of 3.75 megawatts (3,000 amps at 1,250 volts direct current (DC)).
The MCS connector is being advanced by the CharIN organization, with aspirations that it become a worldwide standard charging connector for large and medium commercial vehicles.
