Abstract: A charge equalization apparatus is provided to improve charge equalization by inducing a magnetized current to a low charged battery and performing additional charge equalization. A charge equalization apparatus includes N charge equalization units(1001-100n), an inter-module equalization unit(110), and a voltage detection and driving signal generation unit(120). N charge equalization units are coupled to M batteries, and receive a charge from M batteries. N charge equalization units equalize the charge of M batteries which are coupled in series by discharging an over-charged battery and charging a low charged battery. The inter-module equalization unit is coupled to N battery modules in parallel, and equalizes the charge of N battery modules by discharging an over-charged battery module of N battery modules and charging a low charged battery module. The voltage detection and driving signal generation unit detects a voltage of each of M x N batteries, and sets an average voltage of the detected voltage as a reference voltage. The voltage detection and driving signal generation unit generates a driving signal based on the detected voltage value and the reference voltage. The voltage detection and driving signal generation unit controls the driving of N charge equalization units and the inter-module equalization unit by providing the generated driving signal to N charge equalization units and the inter-module equalization unit.
