Are charging durations getting longer?

The Data Science team currently has a model that predicts the number of open chargers based on average vehicle charging duration. This allows for them to send notifications to previous users when it might be a good time to charge. However, the team believes that average charging duration may have changed since the last time they trained their model. Can you validate this for them?
