Doesn't exist for the mokka but exactly 80% is hugely misinterpreted anyway.
Different use patterns might allow different people to charge to different percentages roughly.
If you might find 60% daily allows you to comfortably get everywhere and never go bellow say 10 or 15% then that might suit you better, if you always need 80% but run things right down to 5% to make it back then charging to 90% would make more sense.
In any event you should regularly charge to 100% but avoid leaving the car at that level for longer than a day to prevent issues, 100% as displayed isn’t 100% of the battery capacity anyway but the higher you charge the slower the process becomes.
So, it depends on what you use to charge the car with as to how you can achieve a roughly 50%, roughly 80% or roughly 95% charge without too much effort but you won't need to be worried about charging too much unless you go to 100% and leave it for a number of days or go to the other extreme and leave it on a few % for a week.
What charge equipment do you have the use of?
