With FleetBoost, you can get the most out of your existing grid connection.
FleetBoost is not a temporary solution, but rather strategic infrastructure, because FleetBoosters can be used permanently on site, are modularly expandable, and can be operated in parallel with further infrastructure expansion. They start immediately and grow with your fleet.
You charge with high power—without waiting for the network operator.
• Use of existing infrastructure
• No building permit required
• No network expansion required
• Plug & play installation
• Implementation in just a few weeks
• Reduction in power prices
Where is the network?
You want to electrify.
Your customers expect CO2 reduction.
The orders are there.
And then reality sets in:
• Limited grid connection.
• Years of waiting for grid expansion.
• Skyrocketing expansion costs.
That's not how you scale an electric truck fleet.
Decentralized generation
FleetBoost can be seamlessly connected to your existing on-site generation systems, such as photovoltaics, wind power, or combined heat and power plants. This allows you to use your self-generated electricity flexibly, reduce peak loads, and significantly increase the economic efficiency of your system.
Super-fast loading & unloading
At the heart of FleetBoost is a high-performance mobile battery storage system that can quickly absorb energy and flexibly release it again when needed. This allows high charging capacities to be achieved even where grid connections or charging infrastructure are limited. FleetBoost enables a reliable, powerful, and flexible energy supply, especially for applications in electromobility.

Frequently Asked Questions
What is a FleetBooster?
A FleetBooster is a mobile energy and charging unit specifically designed for DC fast charging of electric commercial vehicle fleets. The FleetBooster combines battery storage, charging infrastructure, and intelligent energy management. Despite a limited grid connection, e.g., 80 kW (CEE 125A), the FleetBooster can provide up to 800 kW of DC fast charging, actively supporting the scaling of electric truck and commercial vehicle fleets. The system can be deployed overnight on a plug-and-play basis without requiring a building permit.
How does FleetBoost help when network connectivity is limited?
FleetBoost stores energy via the existing connection and makes it available as an additional source during high-power charging.
For which locations is FleetBoost suitable?
For depots, depots, logistics centers, construction sites, and temporary work sites.
Can FleetBoost be combined with solar power or other energy sources?
Yes, the solution can be integrated into existing energy generation and energy management systems.
Is the FleetBooster just a temporary solution?
No – the FleetBooster can be used both temporarily and permanently.
Many companies initially use it as a flexible solution to gain initial experience with electric trucks or to bridge the gap until a possible grid expansion. At the same time, however, the FleetBooster can also be part of the charging infrastructure in the long term.
The integrated battery storage system increases charging capacity, reduces peak loads, and makes efficient use of existing grid connections. That is why many companies are choosing to permanently integrate the FleetBooster into their energy and charging infrastructure.
FleetBoost Hub
Battery energy storage systems (BESS) + high-power charging (HPC) = a virtual power plant
The system buffers energy from the grid and provides it at high power when needed. This enables fast charging of electric vehicles even where existing grid capacity is limited.

About Us
Energy. Simple. Everywhere.
We believe that the mobility transition will only succeed if energy is as flexible as the people and companies that use it. The electrification of transport, construction, events, and agriculture requires more than good intentions – it requires an infrastructure that thinks ahead, adapts, and isn't held back by bureaucracy.
FleetBoost was born out of practical experience. We know firsthand the challenges surrounding charging infrastructure. And we know that these challenges vary from place to place—on construction sites, in depots, at festivals in the middle of the city.
That's exactly why we develop solutions that are mobile, scalable, and affordable. Our FleetBoosters ensure predictable energy costs, flexible deployment, and true independence from the grid—with a product that sets standards in quality, performance, and service.
Our mission: To deliver energy where it's needed. Simply. Fast. Without detours.
