摘要： A battery-charging system is provided that does not require removal of batteries from an impact screwdriver (1) for recharging. The battery-charging system includes the impact screwdriver and a charger (20). The impact screwdriver (1) has a nose (3a) to which a tool bit is attached. The impact screwdriver additionally includes a grip handle (4) containing a battery unit (5) whose terminals (10) for recharging are exposed in a surface of a protrusion (7) of the grip handle. The charger (20) includes a charger circuit encased in an enclosure having a base (21) covered with a housing (22). The housing of the charger is provided with a first receiving recess (29) which can receive the nose (3a) of the screwdriver and a second receiving recess (30) which can receive the protrusion (7) of the screwdriver. The system additionally includes a pair of charge terminals of the charger circuit that resiliently projects into the second receiving recess (30). The charger circuit terminals are brought into electrical contact with the corresponding terminals in the protrusion of the impact screwdriver when the screwdriver is set on the charger. While the battery unit is charged, the entire impact screwdriver (1), not the battery unit alone, is set on the charger (20) with the nose placed in the first receiving recess and the protrusion in the second receiving recess.

摘要： A charging system includes an electric power tool (2) and a charger (1) having internal rechargeable batteries (6) and a controller (9) for monitoring the charge/discharge level of the batteries (6). The electric power tool (2) additionally includes a pair of charge terminals (13a, 14a) for carrying current to charge the batteries (6), a temperature terminal (15a) for outputting to the charger (1) data on the temperature of the batteries, and a data terminal (16a) for outputting to the charger data on the battery charge/discharge level from the controller (9). The charger (1) includes a pair of charge terminals (13b, 14b), a temperature terminal (15b), and a data terminal (16b) that are electrically connected to the corresponding tool terminals when the tool (2) is set on the charger for a charge. The charging system indicates the remaining charge level on an indicator unit (4) based on the received data on the battery charge/discharge level and changes the amount of the charging current based on the data on the battery charge/discharge level and the battery temperature data received from the tool (2).

摘要： An improved charging system for preventing battery deterioration and for accurate indication of the remaining battery charge level includes an electric power tool (2) and a charger (1). The electric power tool (2) is provided with an internal rechargeable batteries (6) and a second controller (9). The charger (1) is provided with circuitry for charging, a microcomputer (19), and discharge circuitry which is comprised of a manually-operated battery refreshing button (25), a discharge relay (23) and a discharge resistor (24). Upon depression of the battery refreshing button (25), the microcomputer (19) causes the batteries (6) of the electric power tool (2) to be charged to a full level and discharged to a predetermined level twice. When the two-cycle operation of full charge and discharge is completed, the second controller (9) of the electric power tool (2) updates the remaining charge level of the batteries (6).
