BMW i3 does that, kinda. I checked the raw data against the claimed battery size, and the in-car 0-100% was 20-80% of the battery. My new Renault Megane E-tech does not do this. Instead it has an option to limit charging to a given percentage (if you set it to 100% it'll ask if it's just next charge) and the manual states that if you have less than 15km range the car might switch off at any moment without notice... Let's just say I was mildly surprised about the latter. Both cars had battery guarantees though, the Megane's is minimum 80% SOH after 8 years or 160000 km, with no reservations against charging to 100%.
