Thanks for that Biffo. That's a pity it isn't possible but I guess only a minor irritation ?
As
@biffo clearly states, it’s not Hypervolts to blame, the software in the car is the issue ( again ).
I have a 5 year old dumb unit that has been adapted to permit delayed charging.
When placing the car on charge, I have become fairly close to estimating how long I need to charge, to hit a certain percentage now.
I have been doing this for almost two years now, so I have had plenty of practice !.
Not the ideal situation, but it works for me.
I just check my SOC when I place the car on charge, then work on the theory that for each hour, it will increase the range by about 25 ish miles.
Therefore I can end the charge at a moment in time to give me my ( close to ) percentage required.
If I only want to charge to 80% ( around 120 miles ) then I can get pretty close to that predicted range on the GOM.
Not great solution, but at least I have some control rather than charging to 100% every single time I charge.
