i think I am missing something...

With the engine running, press and hold the odo reset only brings up next service

If I turn off the engine battery charge does cone up, but shows "SOC__ __ __ " no percentage

Am I missing something or doing it wrong?

.

Engine should be off, keys still in. Works on mine, anyway?

I asked a skoda technician about this and apparently it can take a while to show if your car is new or has had the battery reconnected as it needs to go through a run cycle

My first O3 always showed 80% - regardless of if I had just done a 3 hour motorway run in the daytime, or if I had been playing with VCDS for an hour with the ignition on draining the battery.

 

My second O3 also showed 80% when I got home from collecting it after an hour drive. TBH I haven't looked at it since then in almost a year.

To be honest, its only going to be a voltage test, which is pretty useless on its own. To properly test a battery in needs a drop test, or at the very least, you need to look at the float voltage after you've left the car 24 hours and see what it sits at. That will give you a vague idea on battery health

Can't get this to work on mine. Long press, short press. Keys in, ignition on. Keys in, ignition off. Not the biggest of deals to be honest.

I've found it really helpful when camping, using an electric cool box in the boot. I lose my nerve at 30% - and it's always started fine.

It would be more useful to understand what the percentage relates to. It must be a voltage and I'd hazard a guess zero will be something like 11.8v

You might be better off with a leisure battery whilst camping.

Why MUST it be voltage? Apparently the car measures charge in and out of the battery in a similar way to other modern battery powered devices, so it should have a good idea of the state of the battery without having to rely solely on the terminal voltage.

My Blackvue has the power magic set to cut out parking mode power when the battery hits 11.8v and when it does that the car is showing around 50/60% SOC

I've seen my SOC show 0% only hours after driving it, it then starts first time with no problems. Seems like s gimmick that doesn't work to me.

I agree I think it's a voltage measurement only, mapped to a typical state of charge curve, because the measurement is only taken when it's not under load.

Where did is say it must?

The issue with an arbitary percentage is it doesn't mean much. What does it mean? For example, at what percentage will the car not start? At what percentage are you starting to see sulphation,and as such, the battery starts to degrade? Etc. It would be more useful to see a voltage as that's a figure you can understand. Certainly for me, at least understanding the measurements the engineers have used when assigning a per cent figure to.

Anyone have any idea what the percentages apply to? I wouldn't want to run a battery to under 11.8 regularly if you're relying on that inbuilt indicator.

I also suspect things like the start stop uses this data as well. I had a one series that the stop start stopped working after a couple of years from New and it was the battery was getting a bit tired and wasn't retaining the voltage that bmw had in the settings to use and not stop the engine if the state of the battery at rest was too low.

Did someone solved the SOC ---%  not displayed ?

In post #8 that I quoted.

Hi, I note that there are a number of owners who are seeing non-functioning battery condition meters - can anyone confirm that the SOC meter (battery condition) works correctly on their Octavia? I am being told by my service dept. that it will only operate on cars with KESSY installed - this seems suspect information to me and would appear to make no sense.

The problem with low battery charge would surely be actually unlocking and starting the engine - not how this start is initiated (key-less or key in ignition).

 

I am going to send an inquiry to Skoda CZ. about this.  

 

My car is Octavia 1.4 TSI, SE L estate, manual 7 speed.

I agree, its probably clever enough to know the usable capacity left in the battery.

I have KESSY - doesn't work on mine either

Just tried it in mine (no KESSY).

 

Key in, ignition off, door closed...

 

 

Sorry, it isn't much help.

Hi Silver, Yep, that's exactly what I was getting on mine - Interesting to note that on the 16 plate Fabia I currently have on loan also does not display the battery state of charge, but instead of the battery pictogram being outlined in yellow, this one is white. My Octavia shows the pictogram in yellow exactly as in your video.

That's probably down to whether you have a colour Maxidot or not. My 11 month old 4000 mile MY16 Octavia says --% with a white battery.

My first O3 had a working SOC indicator and it wasn't KESSY.

 

My second one is KESSY and also has SOC.
