The flagship of the eMobility power banks.
The Fleetbooster 40 is the most powerful model among the mobile eMobility power banks and sets new standards in terms of flexibility and charging power. Housed in a 40-foot high cube container, it can be used on a low-deck container chassis or platform trailer. With an impressive storage capacity of 2.1 MWh, it reliably provides energy via CEE connections and two 400 kW charging stations, each with two charging points. The system is complemented by Powerlock connections and an integrated plug-and-play concept that enables immediate readiness for use.
The installed LFP batteries from CATL, the intelligent battery management system (BMS) and modular inverters (PCS) ensure a flexible grid connection of between 80 kW and 800 kW or off-grid, both for feeding into the grid and for drawing power from it.
Fleetboost's mobile battery buffer storage systems are the ideal solution for providing electrical energy flexibly, efficiently and independently - whether to avoid peak loads, to supply e-charging stations or as a self-sufficient energy source in off-grid areas.
The future is inviting. Are you ready?
We bring energy to where it is needed.
Your advantages
- Maximum flexibility: Our mobile storage units can be used anywhere.
- Ready for immediate use: plug-and-play solution without new mains connections or transformer houses
- Cost savings: Charge the Fleetbooster when electricity is particularly cheap and avoid expensive peak loads
- Super-fast loading and unloading: Provision for fast charging of e-vehicles
- Simple integration: integration into existing infrastructure e.g. PV or wind power possible
- Future-proof investment: state-of-the-art LFP batteries from world market leader CATL and first-class after-sales service
Performance up, price down
Our battery buffer storage systems offer you decisive advantages in terms of cost efficiency and sustainability. Compared to conventional storage systems, they impress with a service life of up to 8,000 charging cycles - for intelligent energy use and permanently reduced electricity costs. An optional warranty extension of up to 10 years is available.
In addition, the storage units can be used specifically to reduce peak loads. This ensures even grid utilization and protects you from high peak load tariffs. The result: a stable, economical and independent power supply - even with fluctuating grid availability.
