The evaluation of the real-life charging schedules shows that there is a great potential to cover the mobility energy demand using rooftop PV generation. However, the results also show that uncontrolled greedy charging (as it is mostly the case at the moment) leads to almost worst-case results in terms of coverage (cf. Fig. 9 ).
