A method is disclosed for conducting a pre-charging process of an onboard electrical system of a vehicle and for a charging process of a vehicle battery of the vehicle. The charging process immediately follows the pre-charging process. The vehicle battery is galvanically connected to a first onboard electrical sub-system of the onboard electrical system by a first switch element and a changeover switch and is galvanically separated from a charging path of the onboard electrical system by a second switch element. A line capacitor in the charging path is pre-charged to a first voltage value by a power source electrically connected to the charging path. A capacitor in the first onboard electrical sub-system is pre-charged to a second voltage value by the vehicle battery, wherein the vehicle battery is charged by the power source on the basis of the respective state of charge of the line capacitor and the capacitor.
