A dual-output-port charging circuit is provided, and is configured to multiplex a power transistor on a high-voltage side of a DC/DC conversion circuit and a power transistor of a primary-side conversion circuit of an OBC, so that no cross regulation is generated. The dual-output-port charging circuit includes a primary-side conversion circuit (101), a secondary-side first conversion circuit (102), a secondary-side second conversion circuit (103), a transformer (104), and a controller (105). The primary-side conversion circuit (101) is an inverter circuit, and the secondary-side first conversion circuit (102) and the secondary-side second conversion circuit (103) each are a rectifier circuit. The primary-side conversion circuit (101) includes a plurality of first power switches, the secondary-side first conversion circuit (102) includes a plurality of second power switches, and the secondary-side second conversion circuit (103) includes a third power switch, a fourth power switch, a first winding, a fifth power switch, a sixth power switch, a second winding, a first resonant inductor, a resonant capacitor, and a low-voltage output end. The controller (105) controls the power switches, so that electric energy is output between the primary-side conversion circuit (101), the secondary-side first conversion circuit (102), and the secondary-side second conversion circuit (103).
