The present application discloses a charging circuit for an electric vehicle comprising first and second impedance adjustable circuits connected in series, a high-voltage relay, and a controller, wherein a first end of the first and second impedance circuits connected in series is configured to be connected to a first end of a switch for a high voltage relay, and a second end of the switch for the high-voltage relay is configured to be connected to a DC positive pole interface, a second end of the first and second impedance circuits connected in series is configured to be connected to a DC negative pole interface, and a common end of the first and second impedance circuits connected in series is configured to be connected to a DC ground interface; and wherein the controller is configured to adjust an impedance ratio of the first impedance adjustable circuit to the second impedance adjustable circuit when the switch for the high-voltage relay is switched off, such that a voltage between the DC negative pole interface and the DC ground interface is set to be lower than a preset threshold value, thereby preventing an electric shock due to a high-voltage without the addition of components.
