Save costs with your own electric charging station

With your own charging station, you can charge your electric car quickly and inexpensively at home. Coupled with a solar system, charging your car is also 100% emission-free and optimises your own consumption. Installation is possible in both single-family homes and apartment buildings.

How long does it take to charge my electric car?

The charging time of electric cars primarily depends on four factors

  1. The number of kilometres driven per day*
  2. The charging capacity of the charging station
  3. The car’s charging technology
  4. The battery capacity

* The fewer the kilometres that have been driven, the less the battery needs to be charged.

Calculation formula for the charging time

Charging time = battery capacity in kWh / charging capacity (kW)


The charging time of your electric car is significantly reduced with the installation of a wall charging station. The wall charging station, which is also referred to as a wall box, allows for very high charging capacities, as it was especially designed for the charging of electric cars.

In particular, alongside the charging capacity, it is the battery capacity that is decisive in determining the charging time. The smaller the battery, the shorter the charging time for a complete charging process. However, the range of the electric car is also shorter.

Charging time: charging station vs household socket

Charging station

Charging capacity: 3.6 to 22 kW / Charging time: 2 to 6 hours

Household socket

Charging capacity: up to 3.7 kW / Charging time: 8 to 48 hours

Which charging infrastructure do you need for your electric car? Installation and costs 

The choice of infrastructure depends on the required socket type. Depending on the vehicle manufacturer, different socket systems are used.

With a view to energy efficiency and future further developments, a “smart” charging station is recommended. In addition to the linking of photovoltaic systems (solar energy system), this also allows controlled charging as well as billing with other people who use the charging station.

The installation of the charging station is the responsibility of the building owner. Due to the complex safety situation for the installation, this should be performed by experts. The installation costs vary according to the length of the cable connection.

How to successfully switch to an electric car

Do you have a solar energy system? 

If so, the use of a home charging station is even more worthwhile. The charging of your electric car using your own electricity from the solar energy system (photovoltaics) makes sense from both an environmental and economic perspective. For the efficient use of your solar energy system, it is recommended to purchase a charging station with a clever control system.

Benefits of a charging station with photovoltaics
  • The energy consumption is increased, which has a positive impact on the profitability of your solar energy system.
  • You can charge your electric car more cheaply.
  • You are more independent of the price of electricity.
  • You can charge your electric car 100% emission-free.
