Kempower has introduced a charger designed to solve one of the thorniest problems in electric transport infrastructure: how to serve passenger cars and heavy-duty trucks from the same physical site without building two separate systems. The Finnish charging manufacturer unveiled its Mega Satellite Flex this week at ACT Expo, during its Unplug & Recharge event for customers and partners. It is the company's first dispenser capable of switching between the established CCS standard and the emerging Megawatt Charging System, or MCS, built specifically for electric trucks.
The timing reflects a genuine inflection point in EV infrastructure. CCS, or Combined Charging System, has been the dominant plug standard for passenger electric vehicles across North America and Europe for years, typically topping out in the hundreds of kilowatts. Heavy-duty trucks, however, carry battery packs many times larger than a car's, and charging them at CCS power levels would mean parking a truck for hours rather than minutes. MCS was developed to close that gap, pushing charging power into the megawatt range so that trucks can recharge on schedules that resemble diesel refueling rather than overnight downtime. For fleet operators weighing reliability against cost, questions about network resilience and safety features - including what a kill switch actually does in a connected charging or data system - are increasingly part of the due-diligence conversation around new infrastructure. what a kill switch actually does
One Site, Two Standards
The practical appeal of the Mega Satellite Flex lies in its flexibility rather than any single spec. It supports CCS charging up to 560 kW and MCS charging up to 1.2 MW, with current capacity reaching 700 amps for CCS and 1,500 amps for MCS. Cable lengths are 5 meters for CCS and 2.7 meters for MCS, dimensions that matter more than they might seem, since truck charging bays and car parking spaces have very different layouts and vehicle inlet positions.
Because the unit can serve either standard, an operator building a new charging site no longer has to guess which vehicle types will dominate demand, or commit to a second construction phase later when truck traffic grows. That matters commercially: charging infrastructure is capital-intensive, and idle equipment is dead weight on a balance sheet. A charger that can flip between a passenger sedan and a semi-truck keeps utilization rates higher across more hours of the day, which is the metric that ultimately determines how quickly an operator recovers its investment.
Ready for the 800-Volt Generation
The Mega Satellite Flex also supports newer 800-volt vehicle architectures, an increasingly common design choice among automakers seeking faster charging times and reduced energy losses. Higher-voltage systems allow more power to be delivered without the extreme currents that generate excess heat, so compatibility here is not a minor footnote but a signal that Kempower is building for where the vehicle market is heading, not just where it stands today.
The charger is also designed to slot into Kempower's existing distributed charging architecture, meaning operators already running Kempower installations can add the new unit without rebuilding their power distribution or software backend. An integrated payment terminal option rounds out the package for public-facing sites. Kempower says the Mega Satellite Flex is expected to reach the North American and European markets in July 2026, giving infrastructure planners a firm date to weigh against the accelerating rollout of MCS-compatible trucks.
