Has anyone else done this.
I’m completely running the battery down until the generator stars,I’ve been using the heaters a lot to do it while driving 42 miles to work and then home after a charge at work.
I’ve had the car 2 years so far,she’s a middle 2013 production and 2014 reg.
It was giving 9.9 kw when I first had her,now I’m getting 10.5 -10.9 but slightly less mileage with the heaters set to 24*c.
If I’m not using the heaters I’m getting 10.5 every time and 42-43 miles in temps ranging from -2 to +9 *c.
I’ve not done the battery update,I’ve serviced it every year myself,and tyres are correct LRR and 45 psi.

I've rarely had more than 10.3 from my 2013, no software update, it's been over 15 months since it saw the dealership. I was running 47 miles one way and not using the heater, or very little use, in order to eke out the range on leccy.

You're using some petrol. Funny things happen with the way the regen energy is accounted for, different in 2012s & 2013s. I think the 2012's use it to reduce the energy gone from the battery, so that appears to get refilled a bit. I think the 2013's don't do that, but instead add it to the total energy used. So this 10.9 may mean you regenerated 0.5 kWh during the drive thx to petrol, and you used the usual 10.4 anyway.

That said, I've sometimes seen a figure like this on my 2012, so quite what's going on I don't exactly know. But don't worry, you haven't discovered a perpetual motion machine!

Awww I thought my girl was special 😂.
Anyway my driving style seems to be just right for this car.
I was going to go full bev next year, maybe a kona 64kw, I might just keep her and see what’s going on with work.

Mine, 2013, would reduce the energy consumed on regen, usually just by 0.1kWh on two particular stretches of road on my commute and if I was lucky one of them might reach a 0.2kWh reduction.

That’s what mine used to do,then I read about boosting the battery by running it completely down for a few weeks,I used to get about .2 regen and 10.3.
I’m now getting 10.5 every time,then 10.7 and now 10.9 today.
Seems to be increasing every week I do it.

You can take a look at Opel Ampera 2012 rebalancing battery after software...

If you have GDS2 or a ODBII there's a value for Hybrid/EV Battery Pack Capacity that does go up and down depending on how you drive. Apparently driving in EV only mode tends to reduce that value and give a lower battery usage output.

Eventually after multiple full discharges that value does goes up, but tends to go down again multiple EV only runs.
