The invention discloses a cell voltage equalizing control method using a dynamic reference in a storage battery field. Each cell monomer in a series battery is connected in parallel with an equalization module. A charger is used to charge the series battery. A total output voltage of the battery is sampled in real time. Each monomer voltage of the battery is detected and a reference voltage reference is calculated. When the cell monomer voltage is higher than the reference voltage reference, the corresponding equalization module stops working. When the cell monomer voltage is lower than the reference voltage reference, the equalization module charges the corresponding cell monomer so that voltages of all the cell monomers are equalized. When one cell monomer voltage reaches a monomer protection voltage point, the charger stops charging the battery and each equalization unit continues to carry out boosting charge on the needed monomer till that all the monomer voltages reach the monomer protection voltage point or the monomer voltages are equalized. Output voltages of the equalization units are the same so that a consistency of a final cell voltage is ensured and an equalization effect is good.
