摘要： An electrical power tool includes a motor, a load detecting unit, a trigger switch, and a power supplying unit. The load detecting unit detects a load applied to the motor. The trigger switch receives an instruction. The power supplying unit starts supplying of a driving electrical power to the motor when the trigger switch receives the instruction. The power supplying unit changes an amount of the driving electrical power based on the load detected by the load detecting unit.

摘要： A battery charger is configured to use selective one of two or more power supplies including a commercial AC power supply and a DC power supply. An AC cable is fixedly secured to the body of the battery charger and a DC cable is detachably connected to the body of the battery charger. A single transformer is employed that has a first primary winding to which the AC power supply is connected a first switching element, a second primary winding to which the DC power supply is connected via a second switching element, and a secondary winding to which a battery pack to be charged is coupled.

摘要： A battery pack includes a chargeable battery, a battery voltage detecting section, and a determining section. The battery voltage detecting section is configured to detect a battery voltage output from the rechargeable battery. The determining section is configured to determine a voltage level status of the rechargeable battery based on the battery voltage detected by the battery voltage detecting section. The determining section is free from determining the voltage level status when a rate of change in the battery voltage is equal to or greater than a predetermined criteria. Such a battery pack is used for a power tool.

摘要： When a battery pack having an output voltage of 14.4 V that is connectable to an electric tool in a sliding manner is used as a power supply source for the electric tool that is connectable to a battery pack in an insertion manner and has a rated voltage of 12 V, the electric tool and the battery pack are connected to each other with an adaptor interposed therebetween. The adaptor has an FET that is switched at a predetermined duty of a predetermined frequency. The battery pack and the electric tool are connected or disconnected to or from each other by the switching operation, thereby dropping the output voltage of the battery pack. The voltage from the battery pack is detected. When the detected voltage is out of a predetermined value range, it is judged that the overcurrent or overdischarge has occurred. Then, the FET is turned off to stop the electric tool.
