I suspect that you thought you hit Save but actually didn't, otherwise the charge level would not have fallen significantly, roof box or not. I've done it myself. Either not pressed it, or pressed it twice.
I assure you that was not the case. The "SAVE" icon was lit on the dashboard the whole time. I double checked because the battery level kept dropping.
Honestly, driving in B0 in hills is daft. It would be a lot easier to drive in B5 if you don't want to be changing B frequently. Then if you don't need the full deceleration that B5 gives, you just don't lift the gas pedal that far.
I disagree here. Don't you want to be gliding downhill whenever you don't need to be actively slowing the car down? Say on a long straight downhill. You've already paid for the energy to get up the hill - if you regen too hard, you'll need to accelerate sooner. That's inefficient. And when you're topping a rise, you want to accelerate just enough to get you over, and then immediately start gliding downhill. it's much easier in B0 to just let off the gas than to precisely modulate the pedal in any other setting.
And in B0, you can give your calf muscle a rest for a minute when descending. That's nice on a long drive.
The only way to know if you are braking beyond the level of regen which will be lower in B0 than B5 by the way, is to keep your eye on the power gauge. It will drop into the blue on regen and when it drops no more but you are pressing the brake pedal more, then it's obvious that you are using the mechanical brakes which is not going to help with efficiency.
Thanks. That's what I figured but it's hard to watch the gauge while driving!
