The key factor is how the storage system, power electronics, control system, interfaces and transport concept work together.
That is why Handtmann develops solutions that can be adapted to the location, power requirements and infrastructure.
Loading, drilling, lifting or supplying power generates a wide range of continuous and peak loads. The battery system must provide sufficient energy, cope with sudden changes in load, and be able to deliver its power reliably even after repeated charge and discharge cycles.
Mobile battery containers, trailers and power supply modules are regularly moved between locations. Transport, vibration, dust, humidity and temperature fluctuations place high demands on the housing, cooling system, interfaces and safety design.
From the pilot application through to repeatable series production, the electrical architecture, charging capacity, mains interface and mechanical integration must all be compatible. Taking industrialisation into account at an early stage shortens the path to a ready-to-use product and creates a robust foundation for further variants.

Portable turnkey systems for the storage, control and supply of electrical energy at various locations, for example as Mobile Energy Storage Systems (MESS) or Hybrid Mobile Storage.
Typical configurations
· Battery trailers
· Mobile generator replacement systems
Robust and modularly scalable storage systems for temporary, grid-supported or off-grid energy supply, for example as containerised battery storage or construction site energy storage.
Typical configurations
· Energy containers with integrated batteries
· Power supply modules for construction sites
Flexible systems for charging and rapid energy exchange in electric machines and vehicles, for example as mobile charging infrastructure or battery swap and energy systems.
Typical designs
· Mobile DC charging stations
· Mobile fast-charging systems
· Battery swap systems
Energy supply tailored to requirements for sites, machinery and plant without a sufficiently high-capacity mains connection, for example as temporary power systems or off-grid power supplies.
Typical configurations
· Drilling rigs
· mobile cranes
· Mining and tunnelling machinery
Mobile power storage units provide energy where there is no mains supply, where the mains supply is too weak, or where it will only become available at a later date. They power electrical equipment, reduce generator running times and enable construction site processes with lower emissions.
Applications: Mobile battery storage systems for construction sites · mobile power supply for events and temporary sites · peak shaving for temporary grid connections
Examples: Mobile battery trailers · Energy containers with integrated batteries · Power supply modules for construction sites · Mobile generator replacement systems
Mobile charging infrastructure delivers high charging power directly to the site of operation. This means that electric construction machinery and specialist vehicles can be operated even without a permanently installed charging infrastructure.
Applications: Charging infrastructure for electric construction machinery · mobile fast-charging systems
Examples: Mobile DC charging stations · Battery trailers with charging outputs · Portable fast-charging modules
High-power machinery requires a stable and tailored energy supply, even at off-grid locations. Mobile storage systems can cover peak loads, supplement generator-based systems or enable fully electric operating concepts.
Applications: Power supply for drilling rigs · Battery containers for off-grid applications
Examples: Drilling rigs · mobile cranes · mining and tunnelling machinery · mobile power packs
Replaceable battery systems minimise charging downtime and increase machine availability. Charged energy modules can be prepared independently of the vehicle and swapped flexibly between job sites.
Applications: Swapable battery systems (Battery Swap)
Examples: Battery swap systems for construction machinery · mobile battery modules · transportable energy containers
Development · System Integration · Industrialisation
Handtmann Systemtechnik regards the battery, power electronics, thermal management, control systems, interfaces and mechanical integration as an integrated system. This results in a solution that not only works at the prototype stage, but can also be manufactured safely, reliably and cost-effectively.

01
The system is determined by the operational profileWe do not size energy storage systems solely on the basis of their rated capacity. Peak loads, cycles, charging windows, transport, the environment and available grid connection are all factored into the system architecture. This results in a solution that is technically and economically suited to real-world operation.
02
Mobile and stationary requirements considered togetherPortability, robust housings and changing operating locations are combined with network interfaces, power electronics and energy management. Handtmann integrates these requirements into a comprehensive system solution, thereby reducing the number of interfaces and the effort required for coordination.
03
From development to reproducible series productionHandtmann combines development, validation, industrialisation and series production. This transforms individual energy concepts into robust products that can be manufactured to a consistent standard of quality, scaled up and further developed into additional variants.
Mobile battery storage systems can charge electric construction machinery and specialist vehicles, supply power to building sites and temporary locations, support drilling rigs and mobile cranes, or be used as a replacement for generators and as a peak-shaving system. The specific design depends on power output, energy requirements, duration of use and the existing infrastructure.
A mobile solution is suitable when energy is required at varying locations or where the charging and supply infrastructure needs to remain flexible. Stationary systems are appropriate when the focus is on peak loads, grid support or a permanently installed supply. Hybrid concepts can combine both requirements.
Yes. We take a holistic view of the energy system and coordinate the battery system, power electronics, thermal management, control systems, and charging and grid interfaces. The scope and boundaries of responsibility are defined jointly at the start of the project.
Ideally, this should begin with the load profile, system architecture and packaging. The earlier performance, energy requirements, transport concept, charging infrastructure and design for manufacturing are considered together, the fewer subsequent rounds of adjustments and industrialisation risks there will be.
