ABSTRACT:
A voltage equalizer for battery elements for equalizing terminal voltages of a plurality of battery elements comprises an equalization processing circuit. The equalization processing circuit includes a transformer having basic windings. The basic windings comprise a plurality of primary windings corresponding to the plurality of battery elements and one or more secondary windings, a plurality of switching elements corresponding to the battery elements, a plurality of primary diodes corresponding to the battery elements, and one or more secondary diodes corresponding to the secondary windings. In the voltage equalizer, primary series circuits for carrying current from the battery elements via the corresponding primary diodes to the primary windings and secondary series circuits for carrying current from the secondary windings via the secondary diodes to the battery elements are formed.
