Technology from Domažlice is shaping the future of heavy-duty transport
The core innovation is the Battery Storage Charger 400 (BSC 400) – a unique combination of an Alpitronic Hypercharger 400 kW fast charger and a battery storage system with a capacity of up to 2 MWh. This solution allows e-trucks to charge at up to 400 kW without the need for transformer stations or complex high-voltage grid connections. A standard 400V supply or connection to a solar power plant is sufficient. Grid charging is managed by software to ensure the battery storage is replenished at the most favorable tariff.
The entire system is designed as a mobile unit that can be deployed within hours, making it an ideal solution for logistics hubs, industrial sites, and carriers looking to start electric operations without waiting for grid upgrades.
„From Domažlice, we are now delivering solutions across Europe that enable fast and energy-efficient truck charging in places where it would have been impossible just a few years ago. Combining battery storage with smart energy management brings companies significant savings while reducing their carbon footprint.“
The BSC 400 technology is developed and tested at 3D Lasertec’s facility in Domažlice, where traditional metalworking has evolved into the production of advanced systems for energy and e-mobility.
3D Lasertec supplies structural and assembly components for Alpitronic hyperchargers and assembles battery modules designed for fast charging of heavy-duty vehicles.
“Domažlice is becoming a symbol of industrial transformation. We leverage our expertise in precision metalworking to manufacture technological systems that help transport across Europe transition to cleaner energy,” adds Dipl. Ing. Josef Stauner.
SG Equipment Finance (SGEF) plays a key role in scaling this technology by providing financing for projects focused on sustainable energy and mobility. Carriers can acquire the BSC 400 through loans or leasing with terms of up to 10 years, down payments starting at 0%, and potential incentives from EIB funds.
The offer also includes consulting from ENVIROS, a subsidiary of Komerční banka Group, which helps businesses assess the impact of investments on energy efficiency and ESG.
“We want electric freight transport to be accessible even for smaller carriers. Our financing solutions allow companies to spread the investment over time and immediately benefit from lower operating costs, which offset higher purchase prices within the first year."
The partnership between SGEF, Sunaffairs, and 3D Lasertec demonstrates that energy and transport innovations can emerge outside major cities and still have European significance. The project brings new jobs, know-how, and collaboration opportunities with other Czech industrial partners to Domažlice.
“From Domažlice, we are exporting not only technology but also expertise that helps reduce costs and emissions in European logistics. It’s proof that Czech regions can lead the green transformation,” says Dipl. Ing. Josef Stauner.
Every day that long-haul carriers rely on diesel trucks represents a real economic loss. A recent study comparing total cost of ownership (TCO) for electric and diesel trucks under Czech conditions shows a clear result – operating an electric truck is on average CZK 8 per kilometer cheaper than a diesel truck.
The analysis, prepared by Sunaffairs in cooperation with Mercedes-Benz Trucks, is based on real operational data and considers fuel, electricity, and toll costs valid in 2025. With an annual mileage of 150,000 km, a diesel truck incurs total costs of approximately CZK 30.44/km, while an electric truck costs only CZK 22.11/km. The difference represents savings of more than CZK 1.2 million per year, and with intensive use, it can exceed CZK 2.5 million.
Example 1 – Regional milk distribution (400 km/day, load volume 33,000 liters)
Annual diesel truck costs: approx. CZK 4.44 million, electric truck: CZK 3.23 million. Savings: CZK 1.21 million/year.
Example 2 – Long-haul transport (800 km/day):
Diesel truck costs: approx. CZK 8.6 million/year, electric truck: CZK 6.09 million. Savings: CZK 2.51 million/year.
Savings result mainly from lower energy costs, reduced maintenance needs, and the absence of emission tolls. In many cases, carriers can also benefit from subsidies or tax incentives, further shortening the payback period.
“Electric trucks are no longer an experiment. In the Czech market, their operation is economically viable even without subsidies. Companies that start electrifying their fleets now gain not only lower operating costs but also a significant competitive advantage,” says Dipl. Ing. Josef Stauner, CEO of Sunaffairs and 3D Lasertec, adding: “The economic advantage of electric trucks will continue to grow in the coming years. Diesel prices are rising, emission tolls are increasing, and at the same time, fast-charging infrastructure and models with longer range and higher payload are expanding.”
