  Electric vehicles are booming and with them the required public charging
stations. Knowing how charging stations are used is crucial for operators of
the charging stations themselves, navigation systems, electricity grids, and
many more. Given that there are now 2.5 as many vehicles per charging station
compared to 2017, the system needs to allocate charging points intelligently
and efficiently. This paper presents representative data on energy consumption,
arrival times, occupation, and profitability of charging stations in Germany by
combining usage data of 27,800 installations. Charging happens mainly during
the day and on weekdays for AC charging stations while DC fast-charging
stations are more popular on the weekend. Fast-chargers service approximately 3
times as many vehicles per connection point while also being substantially more
profitable due to higher achieved margins. For AC chargers, up to 20 kWh of
energy are charged in an average charge event while DC fast-chargers supply
approximately 40 kWh.
