The expansion of the charging infrastructure is an important part of the electric mobility. From the customer's point of view, the attractiveness of electric vehicles depends on the simplicity of their use - so charging the battery is a crucial factor.
It is not entirely about the number and distribution of the charging stations, but also the user-friendliness. Decisive factors are unhindered access, a uniform, simple payment system and the charging time. The charging time and the position of the charging station depend on the different application scenarios:
The charging at home, at the workplace, at the destination, each with a short or long dwelling time, as well as the fast charging on the road on longer routes.
As the figure shows, charging at work or at home is the most common. In order to ensure charging in the private installation locations (85%), electric mobility has to be integrated into construction, homeownership and tenancy law.
With the entry into force of the charging station regulation on March 17th 2016, the Combined Charging System (CCS) became the standard for all charging stations in public areas. In advance, some car manufacturers have stated that they will produce all models with CSS in the future. The combined charging system ensures charging on normal charging stations with alternating current (AC charging stations) as well as fast charging with direct current (DC charging stations). This allows all application scenarios to be covered.
The Charging Infrastructure in Germany
The acceptance of Electric Mobility and thus the support of the further market ramp-up must be accompanied by a needs-based and accessible charging infrastructure as well as a positive customer experience during the charging process.
In addition to financial support, further measures and regulations and their implementation are needed to promote the development of charging infrastructure in public and private areas. For that purpose, the VDA has formulated the requirements and recommendations for a customer-friendly charging infrastructure in a paper.
According to the BDEW survey from August 2019, there are now 20,650 public and partially public charging points - including 12 percent fast-charging points. Statistically, about 10 vehicles share a charging point.
In addition to charging stations in public areas, the BDEW survey also included charging stations on publicly accessible private grounds (multi-storey car parks, supermarket parking lots, etc.) .
The charging stations are recorded in the charging station register provided by the BDEW.
