User Manual VC-EVCC

The VC-EVCC transmits the PMax value of the current PMaxScheduleEntry within the CAN

signals VCVCCU_V2G_CurrentPMaxValue and VCVCCU_V2G_CurrentPMaxMultiplier.

The remaining time of the current PMaxScheduleEntry is calculated by the VC-EVCC with

the help of the RelativeTimeInterval information and transmitted within the CAN signal

VCVCCU_V2G_CurrentPMaxDuration.

The VC-EVCC transmits the PMax value of the subsequent PMaxScheduleEntry within the

CAN signals VCVCCU_V2G_NextPMaxValue and VCVCCU_V2G_NextPMaxMultiplier.

Caution

The EV must not exceed the given power limit of the EVSE. Therefore, the PMax value

must be considered for the calculation of the target voltage value and target current

value.

5.9.2.1 Pause and Resume a Charging Session

The VC-EVCC pauses the current charging session if the PMax value of a

PMaxScheduleEntry equals 0W and the duration is greater or equal to 15 minutes.

Note

If the pause time is less than 15 minutes, the VC-EVCC will remain in state

CurrentDemand and not stop the charging communication. In this case, the vehicle

must still follow the PMax value of the EVSE and set the target current to 0A while

charging is paused.

During a charge pause the VC-EVCC could go to sleep or stay awake depending on the

active wakeup reasons. If the VC-EVCC goes to sleep during the charge pause, it will wake

up automatically after the charge pause has finished.

Once the charge pause is finished the VC-EVCC wakes up the EVSE by performing a BCB-

Toggle on the control pilot line and reestablishes a new charging session once the Control

Pilot state changes from B1 to B2.

Caution

The VC-EVCC requires a Control pilot state change from B1 to B2 in order to start a

new charging session
