EV charging for hotels, property owners and businesses

Wallboxes in the car park or garage for your guests, with central billing via charging card or app. We agree with you how charging is billed before the first wallbox goes up. Load management distributes the available power so that kitchen, spa and air conditioning do not compete with the charging points for the connection.

Underground car parks with wallboxes and load management: charging power is shared across the parking spaces so that the building’s connection is sufficient. Under German condominium law, every unit owner can demand permission to install a charging point (Section 20(2) WEG).

We design the base installation so that further parking spaces can be added later without new cable routes, and provide the property management with the documents for the owners’ meeting.

DC fast chargers for company vehicles, delivery fleets and customer car parks. What matters are dwell times, mileage and the existing grid connection; these determine the number and power of the charging points. Where vehicles are parked overnight, wallboxes are often enough in practice; fast chargers where things need to be quick.

A DC fast charger draws high power from the grid for a short time. If the grid connection is too tight for this, it quickly becomes expensive: a larger connection takes time, and with demand metering every new load peak raises the capacity charge in the network tariff.

A battery at the charging point absorbs these peaks. It recharges at low power during breaks and releases the energy during fast charging. In practice this often makes it possible to offer more charging power than the grid connection alone would allow – and with a PV system on the roof, your own solar power is charged during the day too. More on peak shaving

Our Managing Director comes from wind energy: more than 20 years of commissioning plants with converters and inverters and connecting them to the grid, up to high voltage. Technically, a DC fast charger is also a power converter that turns alternating current from the grid into direct current for the vehicle battery. Grid connection, protection systems and commissioning are our daily business.

As a licensed electrical contractor we are registered in the installer register of Stromnetz Berlin GmbH and take care of design, DNO notification, grid connection and the coordination of the trades. Grid references

• Notification – Charging equipment must be notified to the network operator before commissioning; above 12 kVA it requires the operator’s prior consent (Section 19(2) NAV, the German low-voltage connection ordinance).
• Controllable consumer device – Wallboxes on the low-voltage grid can fall under Section 14a of the German Energy Industry Act (EnWG); the network operator may then limit their power during congestion, and in return the network charge is reduced.
• Funding – whether a programme is currently open for your project is something we check case by case before you place the order. Funding
