Disclosed is a battery balancing apparatus and method. The battery balancing apparatus includes a plurality of balancing circuits, each balancing circuit is connected in parallel to a respective battery cell among a plurality of battery cells and the plurality of balancing circuits are connected in series to each other, in one-to-one relationship; and a control unit operably coupled to each balancing circuit. The control unit selects at least one of the plurality of battery cells as a balancing target, based on a SOC of each battery cell, and outputs an enable signal and a balancing message to each balancing circuit connected to each battery cell selected as the balancing target. Each balancing circuit transmits a first wireless signal and a second wireless signal corresponding to the balancing message by using electric energy stored in each battery cell, when the enable signal is received by each balancing circuit.
