A lithium battery pack charging and discharging device with balanced charging and discharging belongs to the technical field of charging and discharging. The objective of the utility model is to solve the problems of low charging efficiency and time consumption of the existing battery active equalization scheme. The voltage of each lithium battery in the lithium battery pack is reported to the microprocessor in real time through the voltage sampling circuit, the maximum value selection circuit selects the maximum voltage from the voltages of all the lithium battery monomers, the minimum value selection circuit selects the minimum voltage from the voltages of all the lithium battery monomers, the difference between the maximum voltage and the minimum voltage is calculated through the difference circuit, and the difference between the maximum voltage and the minimum voltage is calculated. And if the difference value is less than or equal to the threshold voltage, closing the equalization circuit, and if the difference value is greater than the threshold voltage, opening the equalization circuit, discharging the lithium battery monomer with the maximum voltage, and charging the lithium battery monomer with the minimum voltage. The device is used for balanced charging and discharging of the lithium battery pack.
