Yellow battery gauge

[bowfer]

Can anyone advise why the battery level display has gone yellow instead of green?

Remind us what model do you have?...thinking about bms balancing on lfp batteries requiring 100% occasionally but you will soon let us know

Not talking about @bowfer, but it amazes me how few people know that 100% charging is necessary. It seems many dealers do no briefing at all on what the car needs.

SE SR.
I don’t think it’s a battery balance thing, I regularly charge to 100%.
I think it’s a cold battery thing, IIRC correctly other owners have mentioned it goes green again after a while, but my short commute maybe isn’t enough.
Odd that it should pick today when there’s been a lot colder days recently.

Maybe try some battery preconditioning/heating via the app before you start?

Maybe the yellow colour is used to show reduced regen if the battery is cold? Just a guess.

I noticed this the other day on a photo shown on another forum so went and had a look in the manual but couldn't spot an explanation.

That’s going to get very irritating twice a day.

I looked in the manual too, but couldn’t see a thing about it either

Maybe the green reservoir has run dry? ?

Mine changed from green to yellow when my dealer the software upgrade to remove the android Auto watermark.

Maybe they have just changed the colour then?

My car hasn’t been to the dealer, and I don’t think MG are doing over the air updates?

The plot thickens.

Could be:

• Balance (but no, you said recently 100%)
• Temperature (too cold, too hot)
• Health (sincerely hope not!)
• Is doing a balance? (think that only happens during a charge)
• Just another bug

Could it be an indication that it is charging the 12v battery at that time...straw clutching

 

[tsedge]

If it is temperature then it should correlate with weather.

Edit: As @siteguru suggested.

We can rule out too hot, the car had been sitting outside work all day.

Wait a mo, you are in Aberdeen…? What’s the temperature been today?

It’s been mild all day, 8°C now.

Ok… officially baffled!

Surely if it changed colour to offer advice I.e. time for a balance charge the colour of the battery, would change on the app too. Oh Hang on , it's MG!
Could be anything !
