V2G_EVCC_CommunicationSetup_Timeout of ISO 15118-2 might cause problems for WLAN-based charging with ISO 15118-20

Problem: The V2G_EVCC_CommunicationSetup_Timer is running before the V2G session has started. So while the timer is running, we don’t know yet, whether ISO 15118-2, DIN SPEC or ISO 15118-20 will be chosen as V2G protocol for the current charging session. We also don't know which physical layer is going to be used while this timer is running.

In ISO 15118-20 there is no value for V2G_EVCC_CommunicationSetup_Timeout specified because it might cause WLAN-based charging sessions to fail (it is impossible to define a value for this timeout for WPT or ACDP).

However, DIN SPEC 70121 and ISO 15118-2 specify a V2G_EVCC_CommunicationSetup_Timeout value. If one or both of these protocols are implemented in equipment that is capable of ISO 15118-20, too, we might run into a problem for WLAN-based charging according to ISO 15118-20.

--> We should consider deleting all timeouts that apply before the protocol has been selected.
