A vehicle charging circuit is equipped with a rectifier device (PFC), at least one intermediate circuit capacitor (C; c1, C2) and at least one pre-charge/discharge circuit. The rectifier device (PFC) is connected to the intermediate circuit capacitor (C; c1, C2). The pre-charge/discharge circuit has at least one first transfer switch (S1; s2), which is designed to switch the intermediate circuit capacitor (C; c1, C2) is connected to a first potential (+) of the rectifier device (PFC). In a second position (NC), the first transfer switch connects the intermediate circuit capacitor (C; C ') via a discharge resistor (PTC, PTC1, PTC2). C1, C2) and the first pole (+) of the intermediate circuit capacitor (C; c1, C2) are connected together. The transfer switch (S1; s2) is designed to assume the second switching position (NC) in a non-actuated state (NC).
