<p>The present invention relates to a battery pack for cell balancing, wherein the battery pack can be used for an electric vehicle, an uninterrupted power supply (UPS), and a power supply for a smart grid. The battery pack of the present invention comprises: battery cells equipped with first electrode terminals and second electrode terminals; a printed circuit board which is coupled with one surface of the battery cell corresponding to the number of the battery cells and is connected with the first electrode terminal and second electrode terminal; a first connecting terminal which connects the first electrode terminals of the battery cells with other adjacent first electrode terminals; and a second connecting terminal which connects the second electrode terminals of the battery cells with other adjacent second electrode terminals. The printed circuit board is provided with: a cell charger each of which corresponds to the battery cells and charges the respective battery cells; a charging controller each of which corresponds with the cell charger in order to be connected therewith and controls the respective cell charger; a connector which is connected with the charging controller; a connector table which is inserted in the connector in order to connect another printed circuit board which is disposed adjacent to the printed circuit board; and a communicating unit in which a battery managing device disposed outside communicates with the charging controller in a wired or wireless mode.</p> |
