Yes, or rather it is the AUTO that stops the charging process when it is fully charged or your set target in the car (e.g. 80%) has been reached. (There is no option in the charger to set a target in per cent or kW, as the charger does not know how full the car battery is. There is only an optional timer to start the charging process DELAYED (e.g. only in a few hours). (But no timer to switch off after a certain time!)
