Zusammenfassung:	A battery pack includes a parallel series cell group or a series parallel cell group. The parallel series cell group includes two or more parallel cell groups connected in series, each of the which includes three or more cells connected in parallel. The series parallel cell group includes three or more series cell groups connected in parallel, each of which includes two or more cells connected in series. A parallel number, which is a number of the cells included in each of the two or more parallel cell groups or a number of the three or more series cell groups included in the series parallel cell group, is greater than a series number, which is a number of the cells included in each of the three or more series cell groups or a number of the two or more parallel cell groups included in the parallel series cell group.
