K01.FR.48 - Is this even reachable?

[Giavotto]

Description

K01.FR.48 - Precondition -

When a SetChargingProfileRequest with a value for phaseToUse is received AND the EVSE is NOT capable of switching the phase connected to the EV, which is indicated by ACPhaseSwitchingSupported not being implemented or defined as false AND the EVSE is NOT going to use the received phaseToUse.

Within the description of phaseToUse in the ChargingSchedulePeriodType it says:

Optional. Values: 1..3, Used if numberPhases=1 and if the
EVSE is capable of switching the phase connected to the
EV, i.e. ACPhaseSwitchingSupported is defined and true.
It’s not allowed unless both conditions above are true. If
both conditions are true, and phaseToUse is omitted, the
Charging Station / EVSE will make the selection on its
own.

Functional Requirements K01.FR.19 and K01.FR.20 cover the above description.

In order to check the if the final condition in the precondition of K01.FR.48 has been satisfied, the JOET team was planning on using the PhaseRotation variable within the Connector component of the Device Model.

PhaseRotation is defined as a 3 character string consisting of the letters: R, S, T and x depending on what phases the EVSE is using.

Action Items

Is K01.FR.48 even a reachable condition?

If so, what is this covering that is not covered by K01.FR.19 and K01.FR.20?
