I live near the top of a decent hill with ~700 ft descent over a couple miles to get down to town. I usually charge to 85% overnight, and because of the mostly downhill ride, I actually get into town at 86%-87% before getting on the Freeway and start to eat into the battery. Does anyone know what happens if I was planning for a long road trip and wanted to charge up to 100% overnight - would regenerative braking try to charge above 100%, or is the braking logic smart enough to know not to charge, and instead use the caliper brakes until the battery is <100%?

Recup is very limited with 100% charging. You have 2 options:

1. Charge to 95% and take the "free" recup energy.
2. Charge to 100% and heat up the friction breaks a bit.

there is no regen when at very high SOC levels, there is no place to put the kw gained by regen.

Maybe out of the main topic but , do you think when going downhill is it better to regen by applying the brake gently or turn on the actual regen ? I’ve always wondered..

Thanks everyone! That was my assumption, but didn't know in-practice how Porsche set the system up.

In terms of regen, I usually try to use the auto-regen when possible - while I think they are equally efficient, the "slower" regen will be easier on the battery and create less heating in the system, so overall a bit healthier for the battery (albeit, likely in the noise compared to the major charging cycles).

try it! there is always regen at 100% but way less. it could get to 101% as the shown SoC is only a calculated net value, not comparable with Tesla. Be also aware that (at least my) Taycan have a short non-regen brake cleaning timespan every morning.
