Atlas Copco has launched the FCS 220-240 mobile rapid charging station for electric construction vehicles, site equipment, and temporary power applications.
The towable unit combines a 232kWh battery with up to 220kW DC output and 50kW AC output. It is designed for equipment including electric excavators, loaders, and trucks, while its IP55 rating provides resistance to dust and water ingress.
Atlas Copco says customer tests have shown that the FCS 220-240 can deliver up to five additional operating hours per day from one hour of charging. Multiple connectors allow several machines to be charged at the same time.
The system can be recharged from grid connections, EV infrastructure, or generators while continuing to supply power. Dynamic Load Management is used to balance charging demand with auxiliary loads, while RFID authentication, OCPP support, multi-level user access, and remote monitoring are intended to support control across multi-contractor worksites and hire fleets.
The launch comes as electric construction plant moves from demonstration projects into practical deployment. Electric compact machines, access platforms, compressors, and support vehicles are now increasingly available, but charging remains one of the main limits on wider site use.
Permanent high-power charging is rarely available at the point where projects need it. Many sites operate before permanent electrical connections are installed, and temporary supplies are usually planned around welfare, lighting, tools, and tower cranes rather than rapid plant charging. On remote, early-stage, or infrastructure projects, grid access may be limited or absent.
Mobile charging changes that equation by moving stored energy to the machine rather than requiring the machine to return to a fixed charger. Its usefulness depends on real operating patterns: duty cycles, shift length, recharge windows, site layout, and the number of machines drawing power.
Electric plant adoption also requires a more detailed approach to site energy planning. Diesel logistics are familiar and relatively flexible, even where they bring noise, emissions, and fuel-management challenges. Battery-electric equipment demands closer attention to kilowatt-hours, peak load, charging sequence, connector compatibility, and utilisation data.
Temporary high-power charging is increasingly an electrical design issue as well as a plant-management decision. Charging systems for temporary power sites need careful consideration of earthing, cable routes, segregation, fire strategy, access control, and emergency procedures.
The product sits within a wider change in plant supply, where machines are increasingly supported by telematics, charging infrastructure, finance, safety systems, and software. Recent plant and technology launches at Hillhead showed the same shift, with manufacturers focusing on productivity, protection, monitoring, and connected support alongside core equipment.
Rental companies may find mobile charging particularly useful because it allows electric machines and charging support to be supplied together. Customers can trial electric plant without committing immediately to fixed infrastructure, reducing the risk that equipment remains underused because the site cannot support it.
Urban contractors also face growing pressure to reduce noise, improve air quality, and limit generator runtime. Battery-supported charging can help where machines are used intermittently, where grid trickle charging is available, or where generators can run more efficiently by charging a battery rather than idling through fluctuating loads.
The technology does not remove the need for an energy source. On high-utilisation sites without sufficient grid capacity, generators may still be part of the charging chain. The operational benefit lies in buffering demand, reducing inefficient runtime, and allowing electric machines to work where fixed charging is not yet practical.
As contractors plan for lower-emission sites, equipment selection and power strategy will need to be considered together. A battery excavator, charger, temporary distribution system, and grid connection cannot be treated as separate decisions if the site is expected to run efficiently.
The FCS 220-240 is aimed at the transition period now facing the market. Many contractors want to test electric plant, but few sites are fully prepared for fixed rapid charging. A towable charging station provides a bridge between diesel-dominated operations and the more carefully managed energy systems that electric construction equipment will require.
