The invention relates to the technical field of vehicles, and provides a charging and discharging circuit which comprises a power battery, a switch module, a motor and a charging and discharging interface. The switch module is respectively connected with the power battery, the motor and the charging and discharging interface; when the switch module is configured to be in a charging mode, a first charging voltage received by the charging and discharging interface is converted into a second charging voltage through the switch module and the motor so as to charge the power battery; wherein the second charging voltage is higher than the first charging voltage; and when the switch module is configured to be in a discharging mode, first discharging voltage output by the power battery is converted into second discharging voltage through the switch module and the motor, so that the charging and discharging interface discharges. According to the technical scheme, the problems that in the prior art, the cost of the whole vehicle is increased and the arrangement space of the whole vehicle is occupied due to the fact that an additional voltage boosting or reducing device is added can be solved.
