摘要： An impact power tool includes an impact mechanism for applying a striking impact to an output shaft by using an output power of a motor. A strike detection unit detects the striking impact applied by the impact mechanism to obtain a striking timing and a striking speed detection unit calculates a striking speed from the striking timing obtained by the strike detection unit and a rotation angle of the motor obtained by a rotation angle detection unit. A control unit counts the number of striking impact detected by the strike detection unit and stops the motor if the number of striking impact reaches a predetermined strike number. The control unit is designed to correct the predetermined strike number when the striking speed obtained in the striking speed detection unit is equal to or lower than a specified striking speed.

摘要： A charger includes an output circuit unit to output a charging current to a secondary battery, a voltage detection unit to detect a voltage of the secondary battery, and a control unit to control the output circuit unit, whereby constant current charging and constant voltage charging are performed. The control unit decreases a constant current value of the charging current by stages during the constant current charging and determines that the secondary battery has deteriorated by using a first voltage drop value of the secondary battery occurring upon first conversion and a second voltage drop value of the secondary battery occurring upon second conversion.

摘要： A charging apparatus includes a battery pack, which includes a cell voltage detection unit outputting a signal if a detected cell voltage is not smaller than V1, and a temperature sensor detecting a temperature of the battery pack; and a charger, which includes a charging control circuit and a pack voltage detection unit detecting a voltage across two terminals of the battery pack. If the detected temperature from the temperature sensor exceeds 0° C., the charging control circuit switches to a constant voltage charging when the signal from the cell voltage detection unit is received; and if otherwise, the charging control unit switches to the constant voltage charging when receiving the signal or the detected pack voltage exceeds V2, whichever occurs first.
