It's very useful to be able to show and download metrics about the current (each phase) and opcodes during a configurable start and stop interval.
This is essential in reporting errors to the car manufacturer and to verify that the charge scheduler actually works with the planned time settings.
Power together with current is interesting (if the charger can measure the power factor) since it is the power you are charged for and which actually charges the battery - not the current directly.

Completely agree. Often the current in each phase is not interesting, but the power tells if it's on full speed or not.
