Poll: What BECS (battery software) version are you on?

There are a few reports of BECS (battery energy control software, also known as BCM) units receiving over-the-air software updates recently. I thought it would be interesting to see what version people are running, and if they have noticed an update. When my car recently updated to TCU 19.2 and InControl 20C, I did not see any changes. It's also possible that their are country specific versions.

You can check your version by going into the same software update screen where you would check your InControl version. Note that you have to be on a newer TCU version (16.2?) in order for the BECM version to display.
Also note that the list of versions is likely not comprehensive; if it isn't represented in the list, mention it in the response and I'll see if I can add it.

Go to the software update screen, scroll down (top of the screen should be about the infotainment system), and ask for an update if you don't see anything. It should appear there

Fun fact, you can't see the number with the french language. The translation for "battery energy control system" is too long for the screen... :) I had to set it to English to see it.

The car needs to be on TCU 18.2 or 19.2 to display the BECS version. Otherwise it will be blank. You can try to push "check for updates", it may show the number then.
As my car is on TCU 17.2, I am hesitant to vote, as it could be one the numbers shown, but also something else.

Mine is blank when I first look at the BECS screen.
I tried about 6 times to look for new software and got notice "up to date" each time.
Finally, I returned to home screen, then back to software update, then it finally showed up.
Just another I-PACE quirk.

I have just noticed that on the BECM and BCCM module, we can read the following PID on the canbus:
(BECM) F121: J9D3-14C197-BP,
(BECM) F124 : J9D3-14C198-AA,
(BECM) F180 : J9D3-14C200-AE,
(BCCM) F120 : JPLA-10C772-BC,
(BCCM) F124 : JPLA-10C773-AC,
(BCCM) F125 : JPLA-10C773-BE

and my version number is : BP-AAE-BC-AC-BE.

Can't be a coincidence. So this number must be a combinaison of different pieces of software version in BECM and BCCM module.
If you can't read it on the IMC screen, you should be able to get it on the canbus.

After going back and forth with my dealer for over two weeks, they finally added my VIN number to TOPIx and within a few minutes my update was available over the air. The update from 16.2 to 19.2 went smoothly and now I can see the battery information.

Which letters should I be looking at?

I see mine is different in multiple sections.

My VCS and BECS both show up blank. My dealer checked and said the VCS is up to date, but the BECS is not. However, Jaguar has instructed them to not update anything unless the vehicle requests it so they are refusing to do so. I asked them about OTA and while I get OTA updates for infotainment, they are saying this is the only module available for OTA, not VCS or BECM. :mad:

My service center is being difficult to work with. Can I ask who is your dealer? Please PM me if you can. Perhaps I will talk to the service center there and see if they can enable via Topix.

I drove mine today, didn’t feel any different, but it was only a very short drive (2km to and from) at low speed. I didn’t pay any attention to regen either, that wasn’t on my mind. I will report back here next time I’ve been out driving.
