Energy usage data from apps too good?

[playjack]

I am getting super efficient energy consumption data coming out of my FordPasa app. Seems something is off. I get as high as 15.1 km/kwh or 9.4 mi/kwh. I am getting average 4.5 km/kwh or 2.8 mi/kwh. Thoughts? Thanks for chipping in.

yes, good conservative driving can net similar numbers to yours - I've certainly had times of 2.8m/kwh, or even better, in the best circumstances - I've seen much lower numbers in high winds, and fast speeds : )
I started yesterday with a full battery at 265 miles on the guessometer. I drove in very high winds for 170 miles to and from a meeting, mostly at 65mph or similar speeds. I arrived home with a 2.2m/kwh average, with about 40 'miles' left in the tank. Not a great day, compared to most, but that is the effect of the elements of driving.

The Ford EV driving data has known issues. Sometimes in My EV Driving, the miles driven will be way high, showing absurd efficiency.

Tip - when it doesn't match the efficiency you see displayed on the dashboard, it is wrong.

Went on a trip with our Mach-E several weeks ago. We got 2.7 miles per kWh overall. This Trip and Trip 1 displayed 3.0. Bad data, didn't reset.

Just one of many examples of crap data:

It is those trip data with super high efficiency mileage that is just simply too good to be true. I agree that if it doesn't match the info on dashboard it's off. Another means is I will compare how much kwh I added/ charge after the such data and almost always I get almost double the kwh on added.

My super high efficiency drives per the app are usually a combination of the kWh used of the actual drive and the miles from that drive plus the previous drive. The app also misses a lot of drives.

If you assume odometer and fuel gauge (% battery) are correct, using 131 kWh, check the numbers by driving that route again.

On a recent trip, I was getting 2.3 - 2.4 miles per kWh with my Mach-E. This Trip, and Trip 1, both reset, showed 3.0. You can't trust anything but the odometer.
