Press Release: DB Intermodal Services Resolves Loading Bottleneck with FleetBoost’s Mobile High-Performance Solution

(Greven, April 21, 2026) The future of electric trucks has long been a reality—but in many places, the charging infrastructure is holding back the ramp-up. The German startup Fleetboost is providing a solution and is launching the Fleetbooster 20 and Fleetbooster 40 mobile energy storage solutions, offering a new infrastructure option for high-performance charging of commercial vehicles such as electric trucks. The Fleetboosters enable immediate, fast charging without the need for grid expansion and without long wait times: flexible, scalable, and ready for use at short notice.

Fleetboost was born out of real-world logistics challenges. A lack of charging infrastructure, high electricity prices, and lengthy approval processes are hindering the rollout of electric mobility in heavy-duty transport in many regions. “Many logistics companies don’t even know where to start. In addition to selecting the right electric truck, dynamic electricity rates, PV integration, and load management all play a role—it quickly becomes complex,” explains Frederik Rumpf, CEO and co-founder of Fleetboost. “Our goal was to develop a system that works right away—without first having to build a transformer or retrofit the entire site’s infrastructure.”

First regular service with DB Intermodal Services

DB Intermodal Services (DB IS) is a pioneer in this field. Together with TFG Transfracht, DB IS is already using the Fleetbooster 40 for its electric truck fleet at its Großbeeren site. Despite a grid connection of only 100 kW, charging capacities of up to 800 kW are achieved. Intelligent energy management thus enables off-grid, scalable fast charging at a level that previously required a medium-voltage connection.

DB IS is thus considered the first user and pioneer of this technological solution in intermodal transport. The mobile battery platform supports the electrification of the first and last mile—from electric trucks and terminal equipment to reefer containers. Wherever energy was previously lacking or limited, electric mobility can now be put into practice.

Like an energy storage system on wheels—flexible and scalable

“Fleetboost gives us the flexibility we need to implement electric mobility in combined transport quickly and sustainably. This allows us to electrify our fleet in a flexible and predictable manner,” explains Michael Heinemann, Managing Director of DB Intermodal Services.
“The Fleetbooster basically functions like a smart energy storage system with charging infrastructure on wheels,” says Rumpf. “Energy is slowly fed into the battery system and released again in a flash when needed. This allows multiple electric trucks to be charged simultaneously, even at weak grid connections.”

Flexible & scalable – and applicable beyond logistics

The Fleetbooster 20 and 40 were developed specifically to meet the needs of electric trucks, which require significantly higher charging power and energy capacity than passenger cars. Their applications extend far beyond logistics: construction, agriculture, events, passenger transport, ports, or airports—anywhere energy needs to be available quickly, flexibly, and independently of the grid, the Fleetbooster offers a ready-to-use solution.
With its Charging-as-a-Service model, Fleetboost offers economic flexibility. Customers do not invest in hardware or infrastructure but pay exclusively for usage.
The mobile systems can draw power from PV or wind turbines, store it, and supply it on-site—for example, to forklifts, machinery, or buildings via CEE outlets (125 A, 64 A, 32 A). In this way, they create true energy autonomy—without the need for permits, without waiting times, and without additional grid expansion.
