Pause Communication

[tropxy]

The EV can request a Pause of the communication by sending and PowerDeliveryReq to Stop charging and a StopSession Req with ChargingSession = "Pause".

According to this requirement:

7.6.1 Entering the sleep mode
[V2G3-M07-20] - With receiving D-LINK_Pause.request, the EVSE shall switch to state X1 and may switch the low-layer communication module into low-power mode. The logical network parameter set shall be stored for continuing the data link after the sleeping phase.

[V2G3-M07-22] -  If the EVSE or EV is in “Matched state” and has been woken up from the counter-part station, the low-layer communication module shall be configured to the last known logical network parameter set

iso15118 shall send a message to the application that controls the CP requesting the PWM to be turned off (state X1)
The last NMK and NID shall be saved, so that once the EV/EVSE wakes up the network parameter set can be set directly into the PLC chip without the need of performing the matching process again.

iso15118 shall send a message to the application that controls the CP requesting the PWM to be turned off (state X1)

This also means that the iso15118 needs to have a new method in its interface to do this request (e.g. pause_dlink_session)
