The invention provides a storage battery charging and discharging control circuit and device and an automobile. The control circuit comprises a storage battery, a direct-current converter, a switch structure and a vehicle control unit. The switch structure comprises a control end; wherein the storage battery is connected with the switch structure, and the switch structure is connected with the direct-current converter; the input end of the vehicle control unit is connected with the storage battery, and the output end of the vehicle control unit is connected with the control end; the vehicle control unit is used for determining output voltage based on the electric quantity of the storage battery and outputting the output voltage to the control end. And the control end is used for switching on or off the switch structure according to the output voltage, so that the direct-current converter charges or does not charge the storage battery. According to the control circuit, charging or discharging control of the storage battery is realized, the problem caused by insufficient electric quantity or overcharging of the storage battery is avoided, and the problem of how to control charging and discharging of the storage battery is also solved; in addition, the vehicle control unit controls the switch structure to be switched on or switched off, the control accuracy is higher, and the effect is better.
