Abstract: A charge equalization method and a charge equalization apparatus are provided to decrease a voltage stress applied to a first semiconductor switching element which is series-coupled to a secondary winding of a first transformer, by configuring a transformer in two stages. First transformers(T1-Tn) are connected to N series-connected batteries and lower a voltage of an overcharged battery. A charge storing member(Cdump) stores the energy from the first transformers. A second transformer(TS) redistributes the energy from the charge storing member to the N series-connected batteries. A voltage sensing and driving signal generator(20) detects voltages of the series-connected batteries and generates first and second driving signals. The first driving signal is used to discharge the overcharged battery. The second driving signal is used to deliver the energy from the charge storing member to the second transformer.
