Charge equalization apparatus

The present invention relates to a charge equalization apparatus, which can enable the primary windings (N1) and the secondary windings (N2) of transformers (T1,..Tn) to be easily manufactured, can control the flow of charges into batteries (B1,...Bn) depending on the charged states of series-connected batteries, and can prevent overcurrent from flowing into batteries (B1,...Bn) that are currently being charged.
