2022 Mini SE - In Focus: Range!

[insightman]

Interesting that batteries are being sourced from CATL. Tesla recently announced that the standard range M3's and Y's will be getting LFP chemistry batteries sourced from CATL. Any idea if the ones going in the Mini are LFP? From what I've read LFP should be a win for battery longevity.

Inside EVs reported that CATL would begin delivering LFP batteries to Europe in 2020. Because the MINI Cooper SE was designed around CATL's pouch-style Li-Ion batteries before 2020, I assume its batteries are not based on Lithium-Phosphate chemistry.

LFP batteries are also not as energy dense as regular lithium batteries (~2x more weight per kWh) so would be a poor choice for for the MINI.

The latest CATL LFP batteries are reported to be a lot better at roughly 0.5x more weight but that's still significant and also unconfirmed (I believe)

Whenever I launch your web app in Chrome, the Google Translate popup shows up and asks if I want to translate the page (your app). Is this by design for your web app?

No, not by design. Seems like Chrome does what it wants when it comes to detecting translations. I think I have it figured out though... English-only for now.

I see, the trouble ticket advanced to Tier 3 Platinum Support!

I used @GvilleGuy's shortcut and it calculated 5.07 mi/kWh for my 41-mile freeway commute, whereas my car showed 4.3 mi/kWh. Is what the SE shows cumulative, or just for the trip? The BC readouts aren't all clear to me. I sure wish we had eDrive info back in the app.

I've wondered the same about the Mini's mi/kWh reading. I think someone has posted before how to reset mi/kWh, but I don't remember. Just now I went and checked my car. The values shown in the instrument cluster by pressing the BC button are:

mi/kWh: 4.0
Odometer: 0
Battery: 100%

And the "Mini" status display on the 8.8" screen are all blank lines. So I wonder how to reset the BC mi/kWh value, and also wonder about the Mini stats display - I have not noticed when those values reset.

The SE shows both, depending on where you look.

• The "Trip Computer" screen shows the stats (including consumption) for just the current* trip.
• The "Onboard Information" screen and instrument cluster shows the cumulative average consumption.

*The "current" trip stats can either be reset manually (so cumulative across trips if you don't reset it) or automatically (after 4 hours of being parked--so if you park for 3 hours then drive some more, the additional driving is tracked as part of the "current trip").

Finishing my commute, I decided to treat the whole thing as a single trip: 81.8 miles, 5.14 mi/kWh, 151.46 mile estimated range. Much better numbers than the eDrive ever reported.

Math is good!

So why isn't the robot brain in the SE doing it?

I know, right??

... I did create a free IOS Shortcut which can be downloaded which allows you to quickly calculate estimated range.

I added a couple of steps that allow you to keep a history of your calculations in an iOS Note. I don't want to publish my shortcut as it is mostly your work but you should consider adding it to your original work.

Well guess what iOS 15.0.1 has broken the Append to Note action in Shortcuts. Apparently if you do not have a calculation in your shortcut it works fine. So will have to wait until (hopefully) the 15.1 release. In the meantime it still works on my iPad at iPadOS 14.7.

Sorry - I almost missed this in my notifications list. This is great!! And I saw your next comment about IOS 15 breaking it (ugh!). I would love to update my shortcut, and I'll give you full credit! I can update the video description. Can you share a link either here or send me a message with the changes? Thanks.

EDIT: This shortcut is for the public and I don't mind if you publish it yourself, as well. (In other words, I don't mind if people copy it and post it, etc) It can always be improved. Should probably add an option for km or miles, too. I just haven't had time to look at it.

iOS 15.0.2 - still broken [emoji45]

The shortcut (and the web version) are nice, but... do we really need to go to all this trouble? Is there not an app or service that can pull the data from the ODB and give nice charts and graphs? This should just be built in to the Mini app.

Dang, I wished I had visited this post last week. Basically wrote the exact iOS shortcut you did, @GvilleGuy . Great shortcut! I added the current weather and opening a note (sadly running iOS 15.0 so no append at this time) so I can track how weather affects performance.

I haven't see one yet.

I noticed yesterday that the MINI app charging history now includes odometer reading for each charge (both onscreen and export file). I used the app feedback link to request this feature a month or two ago, but I assume they were already working on it before my request.

You can export/re-export your monthly history and use the new odometer ("Total mileage") column to calculate efficiency for miles driven between charges.

Here's how I'm calculating implied range for miles driven since previous charge in Excel using my entire charging history by date in descending order. (OFFSET function refers to cell below; you can instead refer to the cell directly.)

Miles driven since previous charge:
=odometer - OFFSET(odometer, 1, 0)

Battery percent used since previous charge:
=OFFSET(unplug_soc, 1, 0) - plugin_soc

Implied range since previous charge:
=(miles driven since previous charge) / (battery percent used since previous charge)
...or...
=(odometer - OFFSET(odometer, 1, 0)) / (OFFSET(unplug_soc, 1, 0) - plugin_soc)

Please feel free to reply or PM me if you see a mistake in these formulas.

Edited to add that battery percent used since previous charge can be converted to kWh by multiplying it by 28.9, so you can calculate other efficiency measures such as miles per kWh or kWh per 100 km.

I would be interested in what kind of mi/kWh you have gotten on average… from what I have seen elsewhere it’s around 3.7+/-mi/kWh.
