Fleet sites
Delivery vehicles, care services, service technicians: fast charging between two trips keeps your electric fleet in operation – plannable and without downtime.

Fast chargers (DC)
When charging time becomes a competitive factor: DC fast-charging stations charge electric vehicles in minutes rather than hours – at fleet sites, in front of retail outlets or in public spaces.
Understanding the technology
Direct current straight into the battery
With AC charging, the vehicle first converts the alternating current itself – and the built-in rectifier limits the power. DC fast chargers have the power electronics in the charging station: the direct current flows straight into the vehicle battery, typically at 50 to 400 kW.
- 50–150 kW: solid fast charging, e.g. while shopping – depending on the vehicle, around 100 to 200 km of range in about 30 minutes
- 150–400 kW (High Power Charging): fast-charge-capable vehicles charge from 10 to 80 percent in around 20 to 30 minutes – short stops are enough
- The vehicle always determines the actual charging power – the station delivers what the battery can accept
| Charging power | Typical use | Range per 20 min* |
|---|---|---|
| 50 kW | Entry level, existing sites | approx. 80–120 km |
| 150 kW | Fleets, retail | approx. 150–250 km |
| up to 400 kW | Motorway services, charging parks | several hundred km |
* Guide values; depending on vehicle, battery condition, charge level and temperature.

Locations
Where fast charging pays off
DC fast chargers are worthwhile wherever vehicles stop only briefly – or need to be ready for use again quickly.
Retail
Charging while shopping retains customers and extends their dwell time. The charging station in the car park becomes a footfall driver for your location.
Motorway services & traffic routes
On motorways and trunk roads, every minute counts: high-power charging with high availability makes your location a firm fixture for long-distance travel.
Public space
With public fast-charging points, municipalities and utilities create charging options for everyone – including residents without their own parking space.
Planning & operation
Grid connection, backend and calibration law – we consider it all
Grid connection
Fast chargers require substantial connection capacity – depending on the scale, up to the range of a dedicated transformer connection to the medium-voltage grid. We check the capacity at the site, coordinate the connection with the grid operator and size the system economically.
Billing & backend
Anyone selling charging electricity in Germany needs calibration-law-compliant metering and transparent billing for each charging session. We connect your charging stations to a backend – with access control, roaming, monitoring and analysis.
Service & availability
A charging station only earns money when it is running. On request, we take care of maintenance, fault management and remote monitoring – for consistently high availability of your charging infrastructure.
The grid connection at your preferred location isn't enough for fast charging? Then battery-buffered fast chargers (DC/DC) are the solution: an integrated storage buffers the charging power – entirely without costly grid expansion.
