OTA Software Update 10.3.0 - Powertrain, Battery, Parking Brake [PAUSED]

[Horsey]

I live in Tucson too, so I'm literally in the same boat as you lmao. I'd prefer not to kill my battery trying to charge it at ambient temps in June

You'll see the temp meter for the battery move to the right over the summer. For the most part, it's not a big deal. I haven't noticed any degradation to my range yet (beyond the additional energy used to crank the A/C). But I do keep an eye on it when I know I need to DCFC. Tow/Hual mode takes it back to peg the middle in about 15 min if you need it.

So, not sure what happened

Tried to test preconditioning and charging speeds today.

Took off from home and AA was routing to the local charger (had looked it up when stopped). Battery was at 50f and it appeared that it started preconditioning.

Stopped the routing (preconditioning stopped) to test if sport mode or tow/haul would heat the battery. Neither did, over ten minutes of trying.

Stopped and routed to the nearest EA 350. Started driving but no warming of the battery, it stayed in the low 50s. Inlet temp creeped up a slight bit to 57, but the app said the heater was not drawing power. Tried AA routing, no change, tried Ford again, still the same. Not sure why preconditioning didnt work, maybe since it started once and I ended the route, or because I started the Ford NAV with only 15 miles to the charger. Ultimately I have a hard time believing that 50f was warm enough that preconditioning wasn't needed.

Arrived at the EA 350 and started to charge. Speed quickly ramped up to 170kw (426A iirc) but the PTC heater went full blast to 8kw and raised inlet temp to 90f. This continued until the battery reached 60f and then the charger faulted and ended the charge. Tried another stall and the charge started but it only went up to 80kw (215A) and wouldn't go any higher, no heating observed this second attempt with the battery temps in the 60s.

At this point I ended the session and left. SOC at arrival was 41%, at departure it was around 50%.

Attempt number 2

Left home at 45% SOC and used AA to route to a charger (I'm on 10.1.1). Again no conditioning of the battery was observed.

Tried the charger and saw 180kw, but the heater was running at 8kw. Max amperage was 450 into the battery. Heater ran until the charger again faulted (same charger), At this point the battery was in the 70s.

Tried the other cable on the same pedestal and charging kicked off, hitting 171-172kw, but no heater. I have never seen the 180s before, but I have seen the low 170s. However, power into the battery was the same 450A. The charger then faulted again and dropped to 30kw or so, so I gave up and went home.

I would like to believe the reports here of charging at 195kw, and the sustained 145kw would be awesome. I don't know how accurate my test was, what with the charger faulting so many times, but I think it's reasonable to think 10.1.1 is peaking at 450A, or roughly 170kw. If 10.3.0 shows up then maybe we can see.

I might finally bite the bullet and reconnect my TCU to get this update. Still running 4.1.3 right now

These are not total system software versions. They are update numbers. Each update is for a specific module in the truck.
10.1.1 updated the gateway module which controls interconnects to other modules on the truck. It has zero to do with charging or the hv battery.

10.3.0 updates the powertrain modules including the battery control module.

Tesla does more total system software updates.
Don’t expect big sweeping changes with each update. Each update in the series (eg 10.x.x) is part of a whole package. You need all the updates over 6-12 months to complete the package.

You've got a lot of catching up to do.

10.1.3 updates the powertrain modules including the battery control module.

I'm not aware of this, did you just get a 10.1.3 ?

What is popular right now:
OTA Software Update - 10.1.0 - It's karaoke time
OTA Software Update 10.1.1 - Enhanced Connectivity and Power Management

Yes, it's well documented here that the numbered updates are not system wide updates.

It is however the only readily available update version we can all reference to have at least some frame of, well, reference.

Sorry typo on the update number. I have corrected. My post. Good catch. Thanks!

cool, it was just an FYI. lots of folks post about the updates thinking they are system wide upgrades.
