FIELD: electricity.
SUBSTANCE: invention relates to accumulator batteries of an electrically-driven tool. An accumulator battery for an electrically-driven tool includes a multitude of in-series connected battery cells and a multitude of voltage control elements made to implement double voltage control for certain battery cells during charging and discharging and a conductive plate that couples electrically electrodes of the battery cells, which has areas for the receipt of voltage signals corresponding to the voltage control elements, at that the areas for the receipt of voltage signals and voltage control elements are interconnected by means of different conductors.
EFFECT: improved reliability of protection for the accumulator battery of an electrically-driven tool from excessive charging.
