The Megawatt Charging System (MCS) is an emerging EV charging standard that (despite the name) allows commercial electric vehicles to charge at rates of up to 3.75 megawatts—fast enough for heavy-duty EVs to top up their batteries during mandated driver breaks or during loading and unloading.
EVSE manufacturer Kempower has been at the forefront of MCS development, and now that truck OEMs such as Traton, Volvo and Daimler Truck are demonstrating progress toward commercially available, MCS-capable electric trucks, Kempower believes that 2026 will be “the year of MCS.”
Kempower’s MCS deployments to date include:
- Alfredsson Transport, Sweden: Kempower claims to have performed the world’s first public megawatt charging session in August 2025, at Alfredsson’s truck charging site in Norrköpingin.
- Danske Fragtmænd, Denmark: a megawatt charging station for trucks opened in September in Odense, in collaboration with GodEnergi and Kempower.
- ASKO, Norway: a commercial MCS site is powered by Kempower’s distributed charging system.
- Circle K, Sweden: Kempower MCS chargers are up and running at Circle K charging stations in Järna and Vädermotet.
- EV Realty, California: Kempower will supply the MCS infrastructure for a grid-connected MCS site at EV Realty’s truck fleet hub in San Bernardino, California.
Kempower expects the transition to MCS to take place gradually over the next few years, and is therefore pursuing a dual strategy, deploying chargers that can accommodate both CCS- and MCS-compatible vehicles. The Kempower Megawatt Charging System supports the Kempower Mega Satellites, which offer peak power of 1.2 MW, and a variety of different CCS satellites. Existing customers can also upgrade existing systems to MCS by combining two 600 kW Kempower Power Units.
