abstract = {Enhancing electric vehicle infrastructure by forecasting
the availability of charging stations can boost the
attractiveness of electric vehicles. The transportation
sector plays a crucial role in battling climate change. The
majority of available prediction algorithms either achieve
poor accuracy or predict the availability at certain points
in time in the future. Both of these situations are not
ideal and may potentially hinder the model’s applicability
to real-world situations. This paper provides a new model
for estimating the charging duration of charging events in
real time, which may be used to estimate the waiting time of
users at fully occupied charging stations. First, the
prediction is made using the random forest regressor (RF),
and then the prediction is enhanced utilizing the findings
of the RF model and real-time information of the currently
occurring charging events. We compare the proposed method
with the RF model, which is the approach’s foundational
model, and the best-performing prediction model of the light
gradient boosting machine (LightGBM). Here, we make use of
historical information of charging events gathered from 2079
charging stations across Germany’s 4602 fast-charging
connectors. To reduce data bias, we specifically simulate
prediction requests for $30\%$ of the charging events with
various characteristics that were not trained with the
model. Overall, the suggested method performs better than
both the RF and the LightGBM. In addition, the model’s
structure is adaptable and can incorporate real-time
information on charging events.},
