Container Stations for Charging Parks and Electric Mobility: Why Medium Voltage is the Key to High-Performance Charging Infrastructure!


E-mobility is developing at high speed in Germany. More and more companies are electrifying their vehicle fleets, logistics centers are investing in charging infrastructure, charging park operators are building powerful fast-charging sites, and cities are creating new opportunities for sustainable mobility. However, with every new charging point, the demands on the energy supply also increase.

While individual AC charging stations can often still be supplied via existing low-voltage grids, modern fast-charging parks quickly reach technical limits. Even a few DC fast-charging stations can require power levels that are hardly economically and technically feasible without a medium-voltage supply.

This is precisely where modern container substations come into play. As a manufacturer of container substations, EnergieTechnik Becker GmbH develops powerful medium-voltage solutions for charging parks, fast-charging infrastructure, and e-mobility projects throughout Germany with POWERBOXX®.

The future of e-mobility begins with the energy supply

Many operators initially focus on selecting charging stations. However, the real challenge is often in the background.

A modern charging park does not only consist of charging points. It requires a powerful energy infrastructure that can safely absorb high loads and provide them continuously.

With increasing charging capacities, the demands on:

  • Grid connections
  • Transformer capacity
  • Medium-voltage technology
  • Protection systems
  • Load management
  • Supply security

Especially fast-charging sites with multiple charging points often require capacities in the megawatt range. Such requirements can usually only be met in the long term through professional medium-voltage solutions.

Why low voltage is often no longer sufficient

Just a few years ago, many charging points had relatively low capacities.

Today, the requirements are fundamentally changing.

Modern fast-charging stations sometimes reach charging capacities of:

  • 150 kW
  • 300 kW
  • 400 kW
  • 500 kW

If several of these charging points are operated simultaneously, enormous power requirements arise.

Even ten fast-charging points with 300 kW each generate a power demand of approximately three megawatts.

In such magnitudes, conventional low-voltage supply quickly reaches its limits.

Therefore, modern charging parks increasingly rely on medium-voltage connections and powerful container substations.

Why container substations are particularly suitable for charging parks

Container substations offer numerous advantages for charging infrastructure.

They combine medium-voltage technology, transformers, low-voltage distribution, and protection systems in a compact and technically coordinated overall solution.

This creates an energy center that can be precisely tailored to the requirements of the respective location.

Especially for fast-charging parks, the following advantages are crucial:

  • short implementation times
  • compact design
  • high flexibility
  • easy expandability
  • high operational reliability
  • economical project implementation

For these reasons, more and more operators are opting for container substations as the central energy supply for their charging infrastructure.

POWERBOXX®: The container substation for modern e-mobility

EnergieTechnik Becker GmbH develops modern container substations for demanding energy projects with POWERBOXX®.

In the field of e-mobility, POWERBOXX® enables the safe integration of:

  • Medium-voltage switchgear
  • Transformers
  • Low-voltage distribution
  • Protection technology
  • Measuring systems
  • Communication solutions

This results not in a standard solution, but in an individually developed energy infrastructure that is precisely tailored to the requirements of the respective charging park.

As a manufacturer of container substations, EnergieTechnik Becker pursues a holistic engineering approach, in which electrical, mechanical, and safety-related requirements are considered together.

Why charging parks today rely on scalability

Many operators initially plan with a certain number of charging points.

However, experience shows that the demand for charging power often grows faster than initially expected.

Those who dimension their energy supply sufficiently from the outset create the basis for future expansions.

Container substations offer ideal conditions for this.

Due to their modular design, subsequent expansions can often be implemented much more easily than with conventional building solutions.

Especially for:

  • Motorway locations
  • Logistics centers
  • Forwarding companies
  • Commercial parks
  • Fleet operators

this flexibility is a decisive advantage.

Medium voltage as the basis for powerful charging infrastructure

Many people only see the charging station. However, the actual technical performance takes place behind it.

The medium-voltage level forms the foundation of modern charging parks.

It enables:

  • high connection capacities
  • stable energy supply
  • efficient energy distribution
  • safe load control
  • economical operation

Without a powerful medium-voltage infrastructure, many fast-charging projects cannot be realized in the long term.

Therefore, the selection of the right manufacturer for container substations plays a central role already in the early project phase.

Safety plays a decisive role in charging parks

With increasing capacities, the demands on safety also grow.

Modern charging parks must not only function reliably but also meet the highest demands for personal and plant protection.

Especially in the medium-voltage sector, topics such as:

  • Arc fault safety
  • Pressure relief
  • Protection technology
  • Maintenance safety
  • Operational safety

are gaining increasing importance.

POWERBOXX® was developed precisely for these requirements.

Through intelligent safety concepts and tested designs, a solution is created that protects both operators and maintenance personnel.

Arc fault safety in charging infrastructure projects

An often underestimated topic in the field of e-mobility is the safe management of possible fault events.

An arc fault can generate extreme temperatures and pressure loads within a very short time.

Therefore, EnergieTechnik Becker integrates specially developed safety concepts into POWERBOXX® for:

  • Pressure relief
  • Pressure duct systems
  • Hot gas routing
  • Safe room separation

Successful testing according to IEC 62271-200 and IEC 62271-202 confirms the high safety quality of the substation.

Why operators should rely on experienced container substation manufacturers

The selection of the right container substation influences the overall economic efficiency of a charging park.

Not only the technical equipment is decisive, but above all the engineering competence of the manufacturer.

A professional container substation manufacturer considers already in the planning phase:

  • future expansions
  • grid connection conditions
  • transformer design
  • load profiles
  • safety requirements
  • maintenance concepts

This results in solutions that can be operated economically in the long term.

Container substations for public fast-charging parks

Public fast-charging parks place particularly high demands.

Here, large numbers of vehicles often have to be supplied in a short time.

At the same time, users expect:

  • high availability
  • short charging times
  • reliable operation

Container substations form the technical basis for a powerful energy supply.

Container substations for logistics and vehicle fleets

Companies are also increasingly electrifying their vehicle fleets.

Especially for:

  • Logistics companies
  • Forwarding agencies
  • Bus operators
  • Municipal fleets

high power requirements arise.

Container substations enable the provision of the necessary energy and at the same time create reserves for future growth.
