eMobility Public Charging Study

The results of the UScale Public Charging Study provide information about the usage behaviour and criteria of (semi-) public charging infrastructure. The study is based on a survey of over 1,800 EV drivers.

eMobility public charging study on the use of (semi-)public charging infrastructure

Feedback from over 1,800 EV drivers provides a comprehensive insight into the charging profiles, habits and problems of today’s female EV users. The study contains detailed information about the charging profiles of today’s users and enables a unique and in-depth customer understanding.

The results allow conclusions to be drawn about the relevance of (semi-)public charging services and show providers the need for optimisation and further services.

Structure of the Public Charging Study

For each topic, the users were asked about their usage habits, problems with usage and satisfaction. With regard to their charging behaviour, the study participants were asked what criteria they use to decide where to charge (differentiated by usage situation). In addition, the respondents were given the opportunity to communicate their wishes and suggestions for additional services during the charging process in and out of town.

Finally, the participants were asked to make recommendations to manufacturers and providers and to share their assessment of the expansion of the (semi-)public charging infrastructure. The survey contained numerous free text fields, which the respondents also made use of. Thus, more than 7,500 detailed mentions provide very detailed information about where the problems lie and what providers and manufacturers should work on as a priority.

Target group of the public charging study

Only EV drivers who at least occasionally charge (semi-)publicly were recruited. The data collected allows a differentiation according to charging profiles or charging options at home and/or at the employer. Among the respondents, there are more experienced e-car drivers with several years of charging experience as well as young EV owners.

Added value and benefits of the public charging study for …

Manufacturers and operators of charging infrastructure

The study shows manufacturers and operators of charging technology how users charge and what problems they encounter. Together with the aforementioned expansion needs, this helps in the development of new products, the prioritisation of features and the definition of customer benefit criteria.


The survey reveals the problems and potentials for service providers to retain customers in their own offerings. To this end, the analysis helps in the development of pricing models for the future.

Municipalities and funding bodies

The experiences of today’s female EV drivers show municipalities, neighbourhood developers and funding bodies which services need to be developed and installed with particular urgency.

Retail and hotel industry

For providers of semi-public charging infrastructure, the results clearly show the enormous potential for customer loyalty and increased sales that charging offers.


The study shows which requirements have to be fulfilled so that charging offers are perceived as helpful for employees and generate the desired employee loyalty.

Other service providers

The study shows what other service needs EV drivers have during public charging in and out of town.
