  • BATTERY PACK
    Publication number: 20110101917
    Abstract: A battery pack includes a case including external terminals, batteries disposed in the case, and balancing lines connected to each of the batteries and functioning as pathways of a voltage signal transmitted to a controller. At least one of the balancing lines functions as a high current line supplying battery current to the external terminals. Thus, the battery pack may have a simple structure and may be simply assembled using the high current line as a balancing line.
