The present invention provides a charge and discharge control circuit including a control module and a plurality of charge and discharge modules. Each charge and discharge module includes a first switch, a recharger, a battery pack, and an acquisition unit. When the control module receives a discharging signal, the control module controls each first switch to be turned on, each recharger is powered by a corresponding battery pack through a corresponding the first switch. The control module determines a voltage level of each battery pack, according to a voltage signal received from a corresponding acquisition unit, controls the recharger corresponded to the battery pack with a high level voltage to increase an output current, and controls the recharger corresponded to the battery pack with a low level voltage to decrease an output current. The present invention further provides a motor vehicle having the charge and discharge control circuit.
