I'm puzzled. My Dec20 build 330e regularly accepts over 11 kWh on a recharge. (as measured by myenergi app), Does this mean the reserved area of the battery is not 10.2 or 10.4 as previously reported? Has anyone else noticed similar levels of recharge?

Recently often getting over 11kWh but put that down to pre-conditioning (which I use a lot at the moment).
Not sure I really noticed in the warmer months, although suspect the wife would still use pre-conditioning then.

Don’t forget that you’re sending AC to the car. The charger is onboard, and will have significant loses. So 11kWh into the car doesn’t mean 11kWh into the battery.

(Many people think the thing on their wall is a charger. It isn’t - it’s really just a fancy mains socket).

Wow - that's food for thought. As much as 10% losses/ inefficiencies in charging as, in my case it is not preconditioning of the car.

90% efficiency is up there with the best when it comes to charging a battery from AC. Have a read of https://www.caranddriver.com/feature...arging-losses/

Also you have to remember the battery is never really at 0% as it reserves some for eBoost (not sure where I remember reading it but I think up to 25%?!)

So your 11kWh is presumably charging even less?!
