The charging will continue until the car's battery pack hits the programmed SoC.
No need to study more - there is plenty of data indicating you damage the battery when you keep at 100% "real" SoC, although if you live somewhere where it doesn't get too hot, it is less of a concern. Real is in quotes because as you have indicated, VW, as do all manufacturers (Tesla has smaller top and bottom buffers than other manufacturers), has a top and bottom buffer so you can't access the full capacity of the pack. That being said, the pack is probably least stressed at 50% SoC, so if you don't need to charge to 100% indicated SoC every day, then a 80% or even 70% limit will add useful life to your battery pack. A key difference with the e-golf is that it has no active thermal management, so the car can not actively cool the pack if it gets too hot. Other than the Leaf, most other EVs have active thermal management for the battery pack. With all this being said, I believe VW was very conservative with the pack design and made a good choice in the battery chemistry so that the vast majority of e-Golf packs will not lose more than 30% net capacity by the end of the warranty period. Still, I want to lose as little range as possible so the car can continue to serve all my need for 10 to 15 years.
