Canuck, indeed, thinking more about it, I will just leave the charge slider in the 80% position for our daily drives in town nonetheless, which should keep charging cycles between displayed ~50% and 80% (so that's between ~40% and 64% actual charge then). The new S 60 offers enough range for our usage case that we do not have to worry about it anyway.
A more serious concern than battery life in the consideration of regenerative braking, because we live on a hill, which means every time we leave, we go downhill for about 1 km first. If I would charge to 100% (= actual 80%) and the software-limitation of the 75 kWh battery does not allow regenerative braking in that condition, I would have to go all the way down with using the actual brake, and that's really not what I have in mind.
Can someone with a new S 60 answer the following questions:
- Is it true, that regenerative braking does not work when fully charged (= 80% of the actual battery capacity)?
- Is generative braking fully working with a charge level of displayed 90% (= 72% of the actual battery capacity), or is generative braking limited in that condition the more the charge level is to displayed 100% (as it is with our Nissan LEAF)?
Of course I want what's best for the car, we have a very long holding period in mind.
