Battery Trailer

Always renewable energy on site

Mobile emission-free power supply on site

A Battery Trailer is a mobile battery trailer that provides temporary, emission-free power at locations where the electricity grid is missing, limited or not available in time. Battery Trailers are used as a silent and sustainable alternative to diesel generators on construction sites, infrastructure projects and events.

What is a Battery Trailer?

A Battery Trailer is a mobile energy solution on trailer, equipped with an advanced energy storage system. The trailer delivers power directly on site and can be charged via regular EV charging poles or power. Depending on the model, the Battery Trailer also features an integrated water basin, making it widely usable on construction sites and event locations.

When to choose a Battery Trailer?

  • If no or insufficient grid connection is available
  • work is temporary and flexibility is required
  • emission-free construction or operation is a requirement from the client or licence
  • silence is important, e.g. in residential areas or inner cities
  • you are looking for a reliable alternative to diesel generators

The Battery Trailer as a mobile energy source with peak power

A key distinctive advantage of the Battery Trailer is the combination of mobility, continuous power and high peak power.
Whereas a Battery Box is often deployed permanently on site as an energy buffer, the Battery Trailer is designed to be quickly deployable on changing projects, without compromising on performance.

The Battery Trailer not only delivers stable continuous power, but can also short-term peak load on. This is essential for construction and infra applications where machines and plants start up simultaneously.

Case examples:

  • At temporary construction sites without a permanent grid connection, the Battery Trailer delivers instant power, including starting peaks
  • When simultaneously switching on heavy machinery (such as pumps, cranes or rebar machines), the Battery Trailer prevents voltage drop or failure
  • In zero-emission zones and inner-city projects, the work remains fully operational without diesel generator

With this, the Battery Trailer acts as a mobile, stand-alone energy supply offering reliability, flexibility and continuity at any location.

Support in the preliminary stage and in tenders

We actively think along in the preliminary stages of projects and tenders. In doing so, we support:

  • tender documents
  • technical memos and justifications

Simulations and power scenarios

We deliver substantiated insights:

  • Continuous power requirement
  • Available peak power per model
  • Deployment times and charging scenarios

These simulations help clients and consultants understand costs, savings and operational risks.

Proof-of-concept and demos

When required, we temporarily install a Battery Trailer as proof-of-concept. This allows the client to directly experience in the decision-making phase:

  • The silent operation
  • Available power
  • On-site practicality.

Technical integration into the project concept

Our Battery Trailers are plug-and-play and modular. Specific models with associated peak powers and capacities.

These peak capacities show that the Battery Trailer is suitable not only for continuous use, but also for short-term high load, e.g. at:

  • pumps
  • lifting and crane systems
  • rebar machines
  • temporary technical installations

This makes the Battery Trailer a fully-fledged, professional alternative to traditional energy solutions on site.

  • 400 V power current

This allows charging on site, at the yard or via public and private charging points.

Discharged

The Battery Trailer delivers power through the available connections, efficiently and stably, even at low or varying loads. Combined with the buffer function, the system remains reliable under varying conditions.

Emission-free construction and procurement

Battery Trailers are increasingly used in tenders where emission-free construction is demanded. By using a Battery Trailer, you meet more stringent requirements in terms of durability, noise and emissions, without compromising on reliability or uptime.

Grants and schemes

Subsidies and tax schemes are available for the purchase or deployment of a Battery Trailer in many cases, such as:

  • SSEB (Clean and Emission-free Construction Equipment Subsidy Scheme)
  • MIA/Vamil
  • In specific cases EIA

We will be happy to advise which scheme applies in your situation.
