The invention discloses a charging system compatible with a low-voltage direct-current charging pile, a control method and a vehicle. The charging system comprises a power module, a permanent magnet synchronous motor, a motor controller, a battery controller and a whole vehicle controller. The system further comprises a first switch module, a second switch module and a third switch module. The third switch module is used for being connected with a power battery; the input end of the first switch module is used for being connected with the high-voltage output end of a charging pile, and the output end of the first switch module is connected with the third switch module through a motor winding of the permanent magnet synchronous motor and the power module in sequence to form a direct-current boost loop. The input end of the second switch module is used for being connected with the high-voltage output end of the charging pile, and the output end of the second switch module is connected with the third switch module to form a direct-current charging loop; the first switch module, the second switch module and the third switch module are all connected to the motor controller and are all controlled by the motor controller. The system can be compatible with a low-voltage direct-current charging pile for charging.
