A charging circuit is equipped with a storage battery terminal, a direct-current terminal and an alternating-current terminal, which is connected to an alternating-current side of a rectifier of the charging circuit. The direct-current side of the rectifier is connected via a changeover switch to a first side of a DC-to-DC converter, wherein the changeover switch connects the first side of the DC-to-DC converter either to the direct-current terminal or to a first potential of the direct-current side of the rectifier. A second potential of the direct-current side of the rectifier is connected to the direct-current terminal via a diode. The reverse direction of the diode points toward the direct-current terminal. A second side of the DC-to-DC converter is connected to the storage battery terminal, to which the direct-current terminal is connected via an isolating switch. A vehicle electrical system having the charging circuit is also described.
