General
Definitions:
•
EA=EAmount: Amount of energy reflecting the EV's estimate how much energy
is needed to fulfill the user configured charging goal for the current charging
session. This might include energy for other purposes than solely charging the
HV battery of an EV (as defined in ISO 15118).
•
States X1/X2, Ax, Bx, Cx, as well as switch S2 are defined in IEC 61851-1 Annex A
•
N=Number of phases; 1 or 3
•
P=max charging power of the EV in kW
Scope:
A method is proposed based on the 61851-1 Annex A, which allows the EV to signal
its Eamount, max. charging power and number of phases to the charging station.
The target is that the method can be implemented without hardware modifications
to the EVSE or EV, and backward compatibility is made possible.
