How do I know how much I’ve spent for a public charging session?

At the end of each charging session you will receive an invoice. If you have occupied the station inproperly, it will be mentioned on your invoice at the end of the session.

There is also a section in the app with a record of all your previous charging sessions and the corresponding invoices. In the session labeled "My invoices" you will also find a record of all your previous invoices. Find out your kWh in "My Wallet."
