This was my thought. I have no doubt that all these articles by the learned electronics gurus are correct, but it's unclear how much difference their advice makes. Sweating over how to charge the SR to 70% when the app won't allow that to be done automatically? Is it worth it if the gain from doing it is minimal? Even if you plan to keep the car till it falls apart?
How about setting off with only 70% charge, so reducing your range by more than 30% (since nobody in their right mind is going to go down to zero)? How about holding off charging unitl the car is down close to 20%, and then discovering that you need to go somewhere, urgently, right now? All these are considerations that influence real world behaviour.
I'm inclined not to plug it in every night if I've only done short journeys, for the regeneration more than anything, but I'm not inclined to let it go below say 40-50% because I'd be screwed if something unexpected came up. I mean, a huge chunk of the advantage of an electric car is that you can begin every day with a full charge if you want to, and never have to worry about refuelling away from home unless you need to travel further than the range of the car. All these shenanigans significantly reduce the practical range that you're left with.
Certainly unless I have to race off right now, the car can always have half an hour or more on the rapid charger at the end of the road. But this really negates the advantage of being able to have it sitting ready to go, which is such a selling point.
