In case of cars have on-board inverter only capable of 1 phase charging (like most of plug-in hybrid cars have), we can triple (3 times more) supply power capacity by doing a phase rotation.
The phase rotation is done by altering a physical supply cable connection order, but also in a settings of charging point software configuration.
A following picture show how the physical connection is done in case of 3 phase connected TN-network:
A following picture show how the software is configured in case of 1 phase connected IT-network:
