Charge rate discrepancy

[cal]

I just looked at charge logs. I have 2 homes with Tesla chargers.

One is 60/48 amps and the other is 50/40 amps

the one with 50/40 amps added 20% (26 kwh) in 3 hrs 4 min that’s 8.59 per hour and it reported 8.
Tesla showed 9.4
FordPass showed 8
Math showed 8.59

The one with 60/48 amps added to 42% in 5 hrs 3 min. That’s ,10.825 kW/hr and FordPass reported 10.

So FordPass seems to only report whole number before the decimal Point.

I track my Lightning charges. The Fords pass app will give you two different energy added numbers dependent on if the truck is still connected on the charger. If you look at the charge log while the cable is still connected you‘ll get a kWh to a 10th of kWh. Ignore the miles added. Not even close to accurate. This is what you get even while actually charging.

But if you disconnect the cable you get this... just the %. You’ll have to multiply by 133kw to get actual kWh added. I’ve found that they are very close. Within pennies on my calculations.
