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.^[3]

The geometry of the charging plug, for example, was on display at the ABB eMobility stand. The design, long kept secret by CharIN, is triangular, with the tip pointing downwards. In the two upper corners are the (as expected) large receptacles for the two DC pins. The other, smaller pins for earthing and communication are placed in the middle and at the bottom. Since this is still a prototype, the final standard is not to be published until 2024, as mentioned above. CharIN says that the members of the organisation will present their respective products implementing MCS in the coming year. This means that the connector design should already be very close to the final specification.

Building on previous lessons learned, this year's event focused on expanded evaluation to consider more real-world cases for safety and durability within the [Megawatt Charging System] standard, which specifies compatibility with up to 1,250 volts and 3,000 amps.
