Abstract

A method and an apparatus operate a tank system including a tank system of a motor vehicle. The tank system includes a tank for receiving a fluid medium forming a volatile substance and an adsorption filter connected to the tank for receiving the volatile substance which emanates from the tank. A shutoff valve is connected to the adsorption filter and is drivable between an open position and a closed position whereat the tank system is closed off to the ambient. A tank fill-level sensor detects the fill level of the fluid medium in the tank. A fill pipe is connected to the tank for filling with the fluid medium. The fill level is detected while tanking and the shutoff valve is driven into the closed position when the fill level has reached a maximum fill level.
