The invention discloses a vehicle-mounted charging circuit and a vehicle. The vehicle-mounted charging circuit comprises a primary side module, a secondary side high-voltage module and a secondary side low-voltage module, wherein the primary side module is used for being connected with an alternating current power supply and is also used for rectifying alternating current voltage provided by the alternating current power supply to obtain rectified voltage; the primary side module and the secondary side high-voltage module are also used for carrying out first voltage transformation processing and power factor correction processing on the rectified voltage to obtain first direct-current voltage; the primary side module and the secondary side low-voltage module are also used for carrying out second transformation processing and power factor correction processing on the rectified voltage to obtain a second direct-current voltage; wherein the voltage of the first direct-current voltage is higher than that of the second direct-current voltage. Therefore, power factor correction is performed on the rectified voltage through the primary side transformation unit, the secondary side high-voltage module and the secondary side low-voltage module, the workload of the primary side module is reduced, the requirements on elements are reduced, the structure of the vehicle-mounted charging circuit is simplified, and the cost is reduced.
