Thanks to all of you, very useful!
So, now, I know that it's possible to recharge an EV with currents lower than the maximum value defined by a particular "Charging Mode".
Now, I have a couple of technical questions:
1) By reading this Wikipedia page
about Type 1 connector (SAE J1772), I learned that there's a relationship between the "Duty Cycle" of the control signal and the maximum current value allowed by the connector.
At that link, there's a the table entitled "PWM duty cycle indicating ampere capacity
", which shows some current values, each of them associated to a corresponding "Duty Cycle" of the control signal.
Only six current values (6A, 9.6A, 15A, 18A, 24A, 30A) are shown in the table, but I don't think they're the only ones, because it's easy to find on the market adjustable EVSEs which allow to select maximum current values different from these (e.g., 8A, 10A, 13A, 16A).
Am I right?
Moreover (silly question), does the connector technical spec allow to choose (as the maximum current value to recharge the EV) only a value included in a specific limited set
of possible maximum current values?
Or, does the normative allow to choose whichever
maximum current value to recharge the EV, so that it will be limited to the minimum between 1) the selected value on the adjustable EVSE and 2) the maximum current value which the power mains can deliver?
2) Type 1 Wikipedia page
The European versions were equipped with a SAE J1772-2009 inlet as well until the automotive industry settled on the IEC Type 2 “Mennekes” connector as the standard inlet — since all IEC connectors use the same SAE J1772 signaling protocol the car manufacturers are selling cars with either a SAE J1772-2009 inlet or an IEC Type 2 inlet depending on the market.
The bold part says that all IEC connectors (so, even Type 2) use the same "signaling protocol" as the one used by the Type 1 connector (also called SAE J1772), so I guess that even Type 2 uses the same "duty cycle-max current" relationship described above, for Type 1 connector.
Is it right?
