Limiting QC events is easy enough. A daily commuter vehicle can
easily trickle charge over night, and even the measly 40 kWh old used Leaf can get you 200km a charge - assuming an average commute of 20 km for Germany, that's a whole work week worth of battery life. The only time you as an average person actually "need" QC is for the yearly vacation road trip, but as the author writes, renting an ICE or chungus electric vehicle for that occasion is way more cost effective. Admitted: if you don't have access to trickle charge at either the workplace or your home, the situation looks different.
As for the battery health rating, it's easy enough to measure. Go on the highway, keep it at 80 km/h straight and note how much range you get out of it. In practical commute settings, range will be longer than that anyway due to regenerative braking in all that start-stop-start-stop dance.
