Attached are results of a few representative home charge sessions with a Ford Charge Station Pro at 32 amps.

KW @ TED = KW measured by The Energy Detective TED 5000 energy monitor on charge circuit.
KW @ CSP = KW measured by Charge Station Pro as reported by FordPass app.
CHG EFFIC. = KW @ CSP divided by KW @ TED times 100.

Efficiencies are generally between 92% and 95%.

And here is what I got from the Trucks BMS in my followup post. . Thanks for posting. 82% could not be right.....

Final tally.. I downloaded the whole charge from Carscanner and Input charge Voltage and Current and Output as well as battery absorbed power.
40.00160 kWH Into the trucks DC charger from my work level 2 charger.
36.8887 kWH from the charger out to the Trucks battery
Calculates to an Exact 92.2% truck charger efficiency.

Battery kWH calcs are obviously off a bit from the Ford BMS, but the Battery says it absorbed 37.540 kwh .

I am happy to report the lightning onboard charger is truly 92% efficient
taking power from a 208V/32A feed to the battery. I am sure there are some heat losses in the battery but cooling or heating was not needed and the battery temp started at 69.8F and ended at 66.2F during the charge time.

I suppose I can throw my hat in the ring as well.

Last nights charge from ~20% SoC to 80%

Chargepoint says 85.3kW
Home automation says 85.9kW
Ford Pass says 79.6kW so with that around 92-93% "efficiency", same as others.

I didn't check the logs in the truck, but I haven't seen any reason in the past why they would say anything different.
