elephi manages charging for three Volvo FH 540 Electric trucks, two vans and eight passenger cars across the six DC charging points, with access controlled via RFID cards. The platform draws on live vehicle data including state of charge and charges on a vehicle-by-vehicle basis: each vehicle gets what it needs, when it needs it. Charging processes are coordinated and matched to actual operational requirements, while those responsible at roll have full visibility at all times, seeing which vehicles are charging and tracking live charge status directly in elephi.
"We wanted infrastructure that just works, day in, day out, without us having to constantly manage it. IO-Dynamics delivered exactly that: elephi runs quietly in the background, and the vehicles are ready to go when we need them," says Horst Wagner, Managing Director at roll.
One of the DC charging points is also open to external fleets via Depotcharge. Operators can find it, select it, and book it directly on the platform. Access is fully automated via RFID or MAC address, and Depotcharge takes care of billing end to end. For roll, there is no additional workload. Capacity that would otherwise sit idle during quiet periods becomes a new revenue stream, while elephi ensures the company's own fleet always takes priority.
roll Firmengruppe is a strong example of logistics businesses that treat the shift to electric mobility not as something to plan for, but as something to act on now. They bring what it takes: the commitment to electrify, the willingness to invest, and the expectation that technology serves the operation rather than the other way around.
"What we value about working with roll is their clarity of purpose. This isn't about making a statement; it's about building a fleet that's ready for the future. That mindset is what makes electrification at scale possible, and it's exactly the kind of customer we're here for," says Johann Olsen, CEO & Co-Founder of IO-Dynamics.
Mid-sized logistics operators face the same structural challenges as large fleet operators, often with fewer resources and less time to navigate technical complexity. IO-Dynamics sees its role as bridging that gap, from the first conversation through vehicle integration to smooth day-to-day operations.
]]>Spedition Diez is taking the next step towards electrifying its fleet with a dedicated charging hub. To ensure stable, efficient and sustainable operation, the company relies on smart charging and fleet management from IO-Dynamics. The charging infrastructure was set up by LichtBlick eMobility.
The site is equipped with three 400 kW hyperchargers, each with two charging points, and a 450 kWp photovoltaic system. The world’s largest free-standing solar canopy provides both shelter and renewable energy for operations.
Charging heavy-duty trucks requires high power and involves complex load profiles. This is where IO-Dynamics’ software comes in: it orchestrates energy flows in real time, prioritises self-generated solar power, enables multiple trucks to charge in parallel without overloading the grid, and integrates, in collaboration with Rabot Energy, dynamic electricity tariffs into the charging schedule. The result is an integrated system that ensures reliable fleet charging.
A site analysis highlights the impact of intelligent energy management. With just four e-trucks, annual electricity consumption already triples compared to operations without electrification. Without control, only a few vehicles charging at once would overload the connection. Smart charging, however, allows efficient use of the existing infrastructure: peak loads are reduced by around 36%. The charging management from IO-Dynamics also integrates dynamic electricity tariffs from Rabot Energy, ensuring the fleet charges during low-price periods. This delivers clear advantages in terms of cost and energy efficiency. In the future, a two-megawatt battery storage system will buffer solar power and make it available during charging hours. Combined with load management and dynamic tariffs, this setup reduces energy costs by around 25%.
Spedition Diez started with two Mercedes-Benz eActros 600, with the fleet set to expand to seven e-trucks by 2026. From day one, the charging infrastructure has been designed to support growth.
“For us as a logistics company, it’s crucial that electric mobility remains economically predictable. With IO-Dynamics we can make the best use of solar energy, avoid peak loads and keep our operating costs under control.”
– Matthias Diez, Managing Partner, Spedition Diez
Together with Rabot Energy (www.rabot.energy) as the electricity supplier, the project demonstrates how dynamic electricity tariffs can be integrated into the intelligent charging strategy and charging load management in order to operate electric trucks reliably and cost-effectively.
]]>By 2026, the company plans to expand its fleet to a total of ten fully electric trucks. With this strategy, Voigt is consistently advancing the transition towards climate-friendly logistics and underlines that electric mobility is a key success factor for the future of the industry.
For Voigt, electrification is not just about charging infrastructure, but above all about the efficient and economic use of energy. Electricity prices, charging times and vehicle availability must be balanced in daily operations – one of the major challenges for logistics companies.
To address this challenge, Voigt relies on IO-Dynamics. The intelligent charging and fleet management system connects charging infrastructure, vehicles, and PV system into one reliable and efficient setup. This enables predictive charging, reduces energy costs, stabilises the grid and maximises the use of photovoltaic energy. In this way, Voigt builds a sustainable and economical foundation for the electrified fleet.
The benefits go beyond the e-trucks themselves: forklifts and other warehouse vehicles are also integrated, so that the entire operation profits from optimised energy management.
With the combination of high-performance charging infrastructure, one of the first eActros 600 trucks in the state and a clear roadmap for further electric trucks, Voigt-Logistik demonstrates how the transformation of heavy-duty transport can be put into practice.
We sincerely thank Voigt-Logistik for the trust and close cooperation in this forward-looking project.
