The embodiment of the invention provides a charging and discharging circuit, a vehicle and a circuit control method. The charging and discharging circuit comprises an electromagnetic interference filtering module, a controllable switch module, a bidirectional power conversion module, an insulation detection module and a control module. The controllable switch module comprises a first switch and a first switch control circuit, and the first switch is in an on or off state under the control of the first switch control circuit. The bidirectional power conversion module is electrically connected with the electromagnetic interference filtering module through the first switch. The insulation detection module is electrically connected with the electromagnetic interference filtering module. The control module is electrically connected with the insulation detection module and the first switch control circuit, and the control module is used for controlling the first switch control circuit according to a detection result of the insulation detection module, so that the first switch control circuit controls the first switch to be in a turn-on or turn-off state.
