Claim:
1. A battery pack, comprising: a plurality of battery arrays including a first battery array and a second battery array, each of the first and the second battery arrays including unit batteries that have terminals, the first and the second battery arrays being stacked in a first direction; wherein respective polarities of the terminals of the unit batteries of each battery array alternate along the second direction; an insulator facing the terminals of the unit batteries of the first and second battery arrays; and a sensing bar on the insulator, wherein: the insulator includes at least one opening therein, at least one terminal being exposed through the at least one opening, and the sensing bar is electrically connected to the at least one terminal exposed through the at least one opening to sense a state of each of the battery arrays, and wherein the sensing bar extends in the first direction to face the terminals of the unit batteries of the first and second battery arrays being stacked in the first direction such that the sensing bar faces the at least one terminal exposed through the at least one opening and faces another terminal that is covered by the insulator.
