How can I know my HVB is pre-conditioning?

[PilotMark]

I tried to monitor my HVB temp as it Pre-conditioned headed toward a DCFC. Didn't work. Below are the data readings.

Car in my garage all night. Outside temp 26' Garage at 42.
58% SOC
Using odbii and Torque
HVBT 42.8
Drove to breakfast 6 miles and parked outside
HVBT 37.4
outside temp 27
Drove 14 miles to Tesla SuperCharger as a destination in my android auto paired to the Mache. I thought that would start the HVB pre-conditioning.
I monitored the HVBT using odbii and torque as I drove.
HVBT stayed at 37.4 for the trip. It was 34 outside temp when I got the supercharger.
About 4 mins on charge to 61% HVBT temp. was 41
Charge rate was 47.6 KW it indicated 70 when first plugged in but within 30 sec reduced to 47kw. Tesla app said they were 250 KW. I was hoping for a rate of 120 or above.
At 75% SOC HVBT 95 and rate was 48KW - there was no increase in charge rate at the battery got warmed?
Drove home 20 min and HVBT dropped to 77 with outside temp 36.

all temps are F.

Questions:
How do I properly setup navigation so the battery does pre-condition?

What should I monitor with ODBII and Torque to see the battery pre-condition?

Do you have the SYNC update that enables preconditioning through Google Maps?

 

[PilotMark]

looks like I do NOT have the latest update.
According to this post I do not have this update as I don't have the features like the slider as mentioned here:
https://www.macheforum.com/site/thr...-1-0-bluecruise-public-charging-updates.39030

I wish there was an easy way to see what version of each software the car was updated to. Now you just have to see if you have the new features or not.

Question:
When and if I get this update can I use the ODBII and torque app to monitor the HVBT and what should it get warmed up to before charging?

 

[PilotMark]

Hope all my wishes are answered this fast.
Just checked and I got the update late today for preconditioning the battery on the way to a dcfc and I think it now sets the adaptive cruise control to allow me to go to 5mph over the posted limit.
I'll be testing these both later this week.

PS Thanks Mach-Lee for getting me to look to see what version of sync I had.

update:

After the update I put in a tesla supercharger into my phone with google maps and monitored the HVBT. it started at 47 degrees and as I drove to the supercharger it started heating the battery. And the charge rate increase from last time at 50kw to 79kw. The battery SOC was at 75 so I didn't expect it to go much higher.

I'll monitor it on my next long distance trip.

Pre-conditioning when going to a DCFC makes a significant improvement in the rate of charge.

Last week without the update to allow preconditioning the fastest charge I got a Tesla 250 rated per their app was 48kw.

Today after the update and putting in the charger as a destination I got 157.6 as a high and 112 kw continuous. charged 40% to 72%.

Details,
At home prior to start:
HVBT 57.2 F HVBCIT 57.2 Garage temp 57
Idling (is that still an EV term?) at home HVBT 57.2 HVBCit rose slightly
Put in the DCFC destination while still parked
The charger was about 15 mins distant.
As soon as google maps was loaded with the DCFC as a destination I could hear things happening - still parked.
about 1 min after putting in the DCFC HVBT 57.2 HVBCIT 75.2
While driving to the DCFC HVBT rose to 98.6 HVBCIT 120.2
Near the end of the charge HVBCIT was down to 66.2 and I noticed the accc was up to 6.3 amps - I think it was running the AC to cool the battery. The HVBT did come down at the end of charge to 88.

When this works It will make my long trips better decreasing time at a DCFC. 2.5 to 3 times more charging power.

Thanks FORD

Since you have OBD2, there is a statistic for the number of KW the battery heater is pulling. That's a good sign you are preconditioning . The HBV temp it seems you've already found.... it was related to the ACCC that you found.

As you've figured out, you need the correct app levels to enable asking for preconditioning, and the car has to think it's worthwhile (current temp low, power available, etc etc).

Sorry I can't be more specific, away from my car at the moment. I remember it was near the bottom of one of the pages in CarScanner Pro which helps you very little. Hopefully my memory is correct.

Doesn’t preconditioning work through the vehicle’s navigation system? For example, I don’t have Android or Google maps. I use the navigation system.

 

[PilotMark]

I have not tested it using the Ford Navigation after I got the update. Before the update it did not appear to work.
I have seen it quoted here that many of the cars did have it working before me.
bottom line - I think is works with the ford navigation.

I used google maps on my android because the tesla station I wanted because it was $0.30 per KW did not show up in the ford navigation and I didnt think it would work with just an address instead of the DCFC as a destination. Other dcfc near me are 47 to 55 cents per kw.

Preconditioning on way to charger you also have To be 18+ miles away from the charger for it to start preconditioning from what I’ve read. Your SOC will also effect the speed as you were at 58% would be anywhere from 70-90kw If the battery was warm, colder its less.

Isn't it within 18 miles?

As in if you're over 18 miles away it won't start conditioning until you're within 18 miles. So if you start less than 18 miles away it should start conditioning right away, just might not reach optimal since you gave it less time. Is all that right?

 

[PilotMark]

In the test I did I was about 14 miles from the DCFC and as soon as I put in the destination it started to precondition even before I started to drive. and it kept heating the battery as I drove.

Doesn’t preconditioning work through the vehicle’s navigation system? For example, I don’t have Android or Google maps. I use the navigation system.

Yes, can use built in nav or Google maps through Android auto. Android auto is the only way to get preconditioning to work to a NACS Supercharger since they aren't in the Nav database yet.

Preconditioning is active while less than 18.6 miles from the charger (not the other way around).

And Public Charging doesn’t start preconditioning when it sends the charger destination to Connected Navigstion?

It’s been a year since @Ford Motor Company was added to the Tesla Supercharger network. It’s baffling to me that Ford has not yet added Superchargers to the native nav system. What could possibly be the holdup?
