I see. The current is limited... I should say, actively adjusted to 16A. "Actively" because it cannot be done with just a resistor.I don't have a gen 2, but I think the OBCM charges the battery at 3.6KW, and the input from the utility power is 3.8KW to account for the charger losses. The OBCM limits the Input current to 16A, AND, must obey the EVSE "pilot" signal on the J1772 plug. 16*240 = 3.8KW
With 208VAC input, the OBCM still observes the 16A limit, and can only can get 16*208 = 3.3KW, and 3.1KW into the battery.
The gen 2 OBCM is about 94% efficient, the gen 1 somewhat less at 89-90% (IIRC).
Neglecting battery cooling losses, if required.
I have measured both my 2013s with the mygreenvolt app. With the L2 EVSE the max I have seen is 238V x 13.8A = 3.284kW. With the stock Voltec 120V L1 EVSE modified to be a L2 EVSE I have seen 234V x 12.4A = 2.901kW.I see. The current is limited... I should say, actively adjusted to 16A.

So what rate do you guys with Gen 1 see at the chargers' displays?
Hi 2VoltFamilyI have measured both my 2013s with the mygreenvolt app. With the L2 EVSE the max I have seen is 238V x 13.8A = 3.284kW. With the stock Voltec 120V L1 EVSE modified to be a L2 EVSE I have seen 234V x 12.4A = 2.901kW.
Mine was at home not a public charge station. If I used a public charge station it would likely be 208V x 14A = 2.9kW. The Gen 1 is limited to a max 14A and 3.3kW. So if the voltage went above 240V the onboard charger would adjust down the amps.Hi 2VoltFamily
Are numbers that public L2 charging stations show you same as your "mygreenvolt app"?
If L2 shows you 3.284kW then it is no different from Gen 2.
The gen2 Volt charging at 240v is usually 15amps, or 3.60kw, but if the car needs to turn on the TPMS to cool/heat the battery than the power drawn increases to 240v 16amps or 3.84kw. So it switches back and forth between 3.60kw and 3.84 kw as needed. In mild weather, TPMS is not required so the Volt is charging only at 3.60kw. On very hot days in the summer in Texas the AC can run continuously for TPMS and the gen2 Volt is charging at 16amps, 3.84kw.If the real limit for the gen2 (2016-2018) charger is 16A, then if your house has 240V then wouldn't that come out to 3.8 kW? (And if your has 250V then it would be 4.0 kW.) If so, why do they call it a 3.6 kW charger (up from 3.3 kW in gen1)?
