Checklist for the sustainable charging station/wall box


The charging station of the future works efficiently and cost-effectively with intelligent load management. It supports bi-directional communication with the vehicle in accordance with ISO 15118 and is updatable. In addition, it also meets the requirements of the German Measurement and Calibration Act in applications where electricity consumption is calculated on the basis of kWh.

AC charging is the most frequent type of charging as it has the major advantage that the existing AC 230 V/400 V power supply can be used and the charging infrastructure can even be connected to it by an electrical fitter. AC charging stations are also much more economical than DC charging stations. AC charging stations can be found in locations such as homes, in hotels, public car parks or workplaces.

Ask your provider about the following criteria:

Number

How many charging stations are required?

It can be assumed that there will be increasing regulations for parking spaces with a charging infrastructure, at least in public areas. Car parks should therefore be prepared for e-mobility.

Location

What are the requirements associated with the location of the charging station?

Private: In a private house or apartment for personal use

Semi-public: Apartment buildings for tenants, in firms for employees and customers

Public: Public parking areas, multi-storey car parks

Type of charging/charging modes

Decision concerning the type of charging/charging modes at charging stations

Deciding between AC and DC charging also means deciding between rapid charging with high procurement costs at the charging point and slower charging at a much more economical charging station. This decision can easily be made with regard to the use of charging parking areas: AC charging is sufficient in areas in which the charging station is used as a side benefit of parking rather than a stopping point to recharge. This type of charging is becoming more likely as the charging infrastructure expands, particularly when not all vehicles are designed for DC charging.

Plug or cable?

Charging station enclosure

The installation site and type of use (see above) determine the requirements for the charging station enclosure

Charge controller requirements

The most important technical functions of the charging station are determined by the properties of the charge controller.

Operation and maintenance

Predictive planning also takes into account the period after the commissioning of the charging station
