5.9 Charging Schedules

The VC-EVCC supports the usage of charging schedules according to ISO 15118.

5.9.1 Preconditions

The following preconditions must be fulfilled in order to use Charging Schedules with the

VC-EVCC.

 Activation of Charging Schedules via UDS

 The charge cable must be connected during the whole charging session including

charge pauses

 The inlet must be locked during the whole charging session including charge pauses

Note

Details about the activation of Charging Schedules are included in the chapter “UDS

communication”.

5.9.2 Functionality

If all preconditions are fulfilled Charging Schedules can be used for DC charging. During a

charging session the EVSE must support and select the ISO 15118 protocol in state

SupportedAppProtocol. The VC-EVCC will always set the ISO 15118 protocol to priority 1

and DIN 70121 to priority 2.

The available SAScheduleList is transmitted by the EVSE in state

ChargeParameterDiscovery. The VC-EVCC limits the MaxEntriesSAScheduleTuple to 24

within the ChargeParameterDiscoveryReq.

The VC-EVCC will use the first SAScheduleTuple for charging and send the corresponding

SAScheduleTupleID back to the EVSE within the PowerDeliveryReq.

Note

The VC-EVCC does neither consider the SalesTariff information provided in

ChargeParameterDiscoveryRes for charging nor transmit any of the SalesTariff

information on the J1939 vehicle CAN.

The following CAN signals are used for Charging Schedules on the J1939 vehicle CAN.
