I have a 2018 S75D, with about 21K miles on it. In a few days, I'll be heading on a 2000 mile roadtrip. In the past, I've always charged to 100% right before leaving, then charge as much as I needed at a super charger, then stay at a hotel with a destination charger and charge back up to 100% just before I leave in the morning. But lately I have been re-thinking this...
If I charge to 100% before leaving home and I will get to the first super charger with 25%, would it be better(as it pertains to long term battery health) to just charge to 90% instead at home, and arrive at the charger with 15% instead of 25? So far I have charged to 100% about a dozen times in the 12 months I have had the car.
I mean if I need to get to 70% charge before leaving the first super charger, arriving there with 25% vs 15% will save me some time getting to 70%, right? But I travel with my wife and two kids under 7, so usually my car is ready before we are.
