eMobility Private Charging Study 2022


The Private Charging Study asks e-car owners about their experiences with charging at home.

For the study, over 1,100 e-car drivers were surveyed online in Germany, Austria and Switzerland between June and August 2022. In August and September 2022, the study was also conducted among almost 1,000 e-car drivers in the USA.

Deliverables include a PDF report (100 pages) and unlimited access to a dashboard for subscribers’ own analysis of the data.

Target group of the survey

For the study, only e-car drivers who have a home charging station and regularly charge at home were surveyed.  The survey structure makes it possible to differentiate between residents of single-family homes and residents of apartment buildings.

Added value and benefit for charging technology manufacturers and suppliers

The study is mainly aimed at manufacturers and suppliers of charging technology for private charging.

Home charging solutions mostly include smart and standard wall boxes. In addition, in many cases there are integrated photovoltaic systems and the corresponding networking of the systems. The extensive survey and the high sample size provide a precise picture of current user behaviour, problems and wishes.

The results show manufacturers, providers and installers of private charging solutions and their smart integration into building technology what the users’ expectations and wishes are. This provides charging technology manufacturers, retailers and service providers with valuable input on what really matters, which prioritised needs for action can be derived and how they can design their future offers. In this way, they can concentrate their development and investments on the offers that lead to the highest demand, the highest customer loyalty and thus the highest turnover. Furthermore, subscribers to the study receive valuable information on the sales potential of future upgrades and cross-selling offers.

Dashboard for analysis

Many exciting findings only become apparent when the results are evaluated separately according to important customer groups. This allows providers to target their offers to different user segments in a differentiated way. Thanks to the high sample size, subscribers to the study can split the results in the interactive dashboard as they wish and analyse them in detail. In addition, the dashboard shows all pre-clustered verbatim mentions of the respondents.
