Defining MCS
The Megawatt Charging System (MCS) is a cutting-edge, high-power charging solution that delivers significantly quicker charging speeds than traditional Combined Charging Systems (CCS). It was developed specifically for heavy-duty battery-electric vehicles like trucks and buses.
While CCS systems typically provide 50–400 kW of DC power, MCS has the potential to exceed 1 megawatt. To safely manage these higher currents, MCS uses a unique connector distinct from CCS. However, modern electric truck models now come equipped with both types of outlets, allowing compatibility with both systems.
Implications for the Future of Electric Trucks
MCS chargers will make electric trucks a more practical choice for operators covering longer daily distances. Currently, many electric truck owners use the driver's mandatory 45-minute break for "opportunity charging"-brief recharges during downtime. With an MCS charger, charging a truck's battery from 20% to 80% is estimated to take around 40 minutes.
This means an electric truck could regain enough power during a 45-minute break to drive for another 4.5 hours-the maximum allowed under EU regulations. In this scenario, the vehicle itself would no longer be the limiting factor for long-haul electric trucking.

Where Are MCS Charging Stations Located?
The rollout of public MCS charging stations has just started. Last February, Milence opened its first public MCS chargers at the Port of Antwerp-Bruges, offering up to 1440 kW of power.
Other providers have plans to expand MCS infrastructure in the coming years. For example, Iberdrola intends to launch its first MCS charger in Murcia, Spain, with over 1000 kW capacity. In the UK, BP Pulse plans to install MCS chargers at its new Ashford International Truckstop by 2026.
Through the MILES (Mobility Infrastructure for Logistics – Electric & Sustainable) project, Milence has secured up to €111 million from the EU's Alternative Fuels Infrastructure Facility (AFIF). This funding will support 284 additional MCS charging points across 71 locations, with completion expected by late 2027.
The rollout of MCS chargers is likely to be faster and simpler than that of CCS, as it can leverage existing charging station networks. Adding MCS to existing sites will raise grid capacity issues, but many logistical challenges-like site selection, parking setup, and facility construction-are already resolved.
Will MCS Replace CCS?
No-all signs suggest both CCS and MCS will coexist, giving customers a choice based on time and cost needs. For truck owners who don't require MCS's speed and power, CCS will remain a practical option.
Building CCS stations is also more cost-effective, so infrastructure providers will need to decide between investing in multiple CCS units or a few MCS chargers. Most stations will likely offer a mix of both. Still, MCS provides an alternative for businesses that couldn't switch to electric using CCS alone.
