charge values and total charging count

[shyboy]

Why the current charging rate display different in Tesla app?
the 2 different third party apps are showing the same value, but tesla shows different value.

See the screenshots.
2 apps showing current charge rate is 14KW but Tesla app shows 11KW.

After the charging completed, it also shows different value.
2 apps shows 38.47KW and tesla shows 36KW total charged.

Is that mean that I am loosing almost 2KW on every charge?

TIA

The other apps are wrong. 230 V x 48 A isn't 14 kW. Nothing to worry about.

That is an interesting catch. 228.8*48.3=11,051.04 and certainly not 14KWh. I doubt the app developers did not know Ohms low. There got to be more to this discrepancy IMO

thank you, is that mean that the total charged KW also incorrect?
but both of these developers are mis calculating?

kW is a charging/discharging rate (power, like horsepower). kWh is how much you've added or removed (energy, like gallons of fuel). For example, 11 kW for three hours is 33 kWh.

The simple answer to your question: your other apps are wrong. 48 amps * 230 volts = 11,040 Watts, or 11.040 kW, which Tesla rounds to 11 kW. Since these apps can't seem to handle basic electrical math, I would question/doubt all of the other statistics that they're showing you.
