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 be it on land, water or in the air, but other large vehicle charging interfaces are also progressing and being brought into serial production.
