Kempower, a provider of DC fast charging solutions, has announced a major step forward in high-power charging infrastructure with the rollout of its Megawatt Charging System (MCS) technology, addressing the next phase of electrification for heavy-duty electric trucks and commercial vehicles. Designed to support charging power levels exceeding 1 MW, Kempower’s MCS solution enables ultra-fast energy transfer required for long-haul and high-utilization freight operations.
The MCS standard has been developed specifically for electric trucks with large battery capacities, often exceeding several hundred kilowatt-hours, where conventional DC fast charging based on CCS, typically limited to around 350–400 kW, is insufficient to meet operational uptime requirements. Kempower’s MCS technology supports charging currents of up to 1,500 A and system voltages approaching 1,250 V, enabling substantial energy replenishment during short dwell times such as mandatory driver breaks, loading cycles, or depot turnaround windows.
Kempower’s MCS implementation is based on its distributed charging architecture, which decouples power generation from the charging dispensers. Centralized power units deliver scalable DC output that can be dynamically allocated across multiple charging points, supporting both MCS and CCS interfaces simultaneously. This architecture allows charging operators to deploy mixed-use sites, where megawatt-level truck charging and conventional fast charging for light-duty vehicles can coexist without stranded power capacity.
Kempower’s modular design enables infrastructure scalability from early pilot deployments to full megawatt-class installations. Existing sites equipped with high-power CCS chargers can be upgraded to MCS by paralleling power units, such as combining two 600 kW units, without fundamental changes to site layout. This approach reduces capital risk while allowing operators to incrementally transition as MCS-capable vehicles enter service.
MCS places significantly higher demands on efficiency, thermal management, and current handling compared to conventional fast chargers. Kempower’s system design addresses these challenges through optimized DC power conversion stages, high-current cable assemblies, advanced cooling concepts, and real-time control software that manages load balancing and grid interaction. These capabilities are particularly critical in depot and logistics hub environments, where multiple megawatt-class loads may operate concurrently.
Kempower has already demonstrated MCS technology in real-world deployments across Europe and North America, including early public MCS charging sessions at logistics sites and installations supporting commercial fleet operators. These projects validate both the electrical performance and operational feasibility of megawatt-scale charging under commercial conditions.
Kempower is also integrating energy management and grid optimization features into its MCS solutions. This includes compatibility with onsite energy storage systems, peak-shaving strategies, and intelligent power scheduling to mitigate grid constraints, an increasingly important consideration as heavy-duty electrification scales.
