What Are Megawatt Charging Systems (MCS)?

The Future of Heavy-Duty EV Charging

As electric vehicles continue to evolve, charging infrastructure must keep up—especially for heavy-duty transport. Megawatt Charging Systems (MCS) are emerging as a groundbreaking technology designed to meet the intense power demands of large electric trucks, buses, and commercial fleets.

In simple terms: MCS can deliver over 1 megawatt of charging power, enabling massive EV batteries to be fully charged in under 30 minutes. This guide is tailored for the ones who want to understand how MCS works, why it’s necessary, and what sets it apart from today’s fast-charging systems.

Core Features and Technological Fundamentals

Power and Performance

- Charging Capacity: 1,000 kW to 3,750 kW
- Voltage Levels: Up to 1,250 V
- Current: Up to 3,000 A using liquid-cooled connectors
- Standardization: Developed under the Megawatt Charging System (MCS) initiative by CharIN

With this level of power, a heavy-duty EV equipped with an 800 kWh battery can be nearly fully charged in as little as 20 minutes.

Why Do We Need Megawatt Charging?

- Freight transport demands fast turnaround—long charging times cost money.
- Commercial EVs require larger batteries for extended range.
- Fleet efficiency hinges on short charging windows, especially at highway stations.
- High-power charging ensures infrastructure scalability for industrial mobility.
