摘要： A battery pack for an electric power tool includes a control device that determines the necessity of a balancing control to reduce difference in voltages of cells of a battery based upon voltages of the respective cells measured by a voltage measuring device. The control device controls a subject cell, which is subject to the balancing control to discharge via the discharging device when the balancing control is determined to be necessary. A voltage measuring device measures the voltages of the respective cells when a battery charger detecting device detects the connection of the battery charger in a state where the battery has not been connected to the battery charger for a predetermined specified period of time or more and power feeding to the electric power tool has not been performed for the specified period of time or more.

摘要： A battery pack for electric power tool is provided with a battery and a control circuit. The circuit includes a condition satisfaction determination unit, a continuation satisfaction determination unit, and a sleep-mode transition unit. The condition satisfaction determination unit determines whether each of at least one predetermined sleep-mode transition condition is satisfied, and determines whether an all-condition satisfaction state is present, which is a state wherein all of the at least one sleep-mode transition condition are satisfied. The continuation satisfaction determination unit determines whether the all-condition satisfaction state has continued for a predetermined period of time when the condition satisfaction determination unit determines that the all-condition satisfaction state is present. The transition unit stops part of operation of the circuit to shift the circuit to a sleep mode when the continuation satisfaction determination unit determines that the all-condition satisfaction state has continued for the predetermined period of time.
