Abstract
A battery balancing apparatus according to an embodiment of the present disclosure includes a first selection unit to selectively connect each of a plurality of batteries included in a first battery group between a first node and a second node, a resistance adjustment unit to connect a first resistor, a second resistor, a series circuit of the first and second resistors or a parallel circuit of the first and second resistors between the first node and the second node, and a control unit. The control unit determines at least one of the batteries as a first balancing target based on a first voltage signal indicating voltage of each battery. The first selection unit connects the first balancing target between the first node and the second node. The control unit controls the resistance adjustment unit based on a voltage difference between voltage of the first balancing target and a reference voltage.
