Very interesting! Wonder what is going on. Nice catch!

How long before you noticed this discrepancy? A day? A week? (I’m guessing not much longer based on your delivery post). Unusual and unsettling I would say.

This was my first charging session at home. As you could imagine I was watching the app like a hawk ? with excitement until I noticed this weird fluctuation. Hopefully this will be corrected in a future over the air update ??

Well, I sure am glad you were paying attention. Hopefully Tesla, Inc is also paying attention to this forum, as your insight (as well as many others here) could provide much needed OTA updates in the near future

Cybertruck uses a different calculation because it's a different vehicle.

The truck would never get the same miles per hour that a car would.

It's not at all concerning. The truck is probably cycling some onboard load in the background and its software is being more proactive about calculating the rate.

Does the measured amps input change?

What you really want to test is to see how many miles it puts in over an entire charging session, and see if its charging slow or not.

Looks like it may be charging fine as the amperage 48/48 never changed. Possible it is calibrating the calculation of mph only and not actually fluctuating.

Forgive my ignorance, but you’re saying it’s a hyperactive analysis rather than a true fluctuation, am I right? If that is the case, why send that input so instantaneously as to rupture the viewers perception of charge rate? Assuming the ignorance of most owners includes a lack of understanding that the mph charge rate is irrelevant to the consistency of 48A without fluctuation. It is, after all, implemented into the app so as to be visible by the layman.

I’m curious if other owners have noticed something similar with their trucks? It’d be nice to know if it’s an every truck thing or not. Hopefully if it is a little bug it’ll get fixed soon. Great looking truck BTW.

Even if it were a fluctuation, it's not concerning.

The mph is based upon the Wh per mile and the remainder power after all other loads.

The charger always is fluctuating, we just usually don't see it because the software tries to take a long enough sample so the display isn't noisy.

Balancing a noisy display against getting feedback from adding load to the truck (like turning AC on or off) is a tough trick.

There was that guy who drove to Oklahoma and was charging at an RV park...

Got it. So likely just needs “fine tuning” like a giant stainless steel piano

Oh yeah you’re right. It was being discussed as a truck vs. RV park infrastructure problem.

A little of column A, a little of column B ^-^
