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.

摘要： A power tool includes: a battery cell group including a plurality of secondary battery cells; a motor to which an electric power is supplied from the battery cell group through a switching element and a trigger switch; a current detector detecting a current value flowing in a current path; and a controller configured to receive a detection signal from the current detector and controls on/off operation of the switching element. If the current detector detects that the current value flowing in the battery cell group continuously exceeds a given value for a first time period, the controller conducts one of alarm display and alarm control for allowing an operator to recognize that a high load operation continues. If the current value continuously exceeds the given value for a second time period longer than the first time period, the controller turns off the switching element to interrupt the current path.

摘要： When a main switch (12) is turned ON, an electric operating machine (1) is put in the standby mode. With a trigger (13) being pulled in the standby mode, a power supply circuit (16) applies a voltage to a drive part (30). The power supply circuit (16) adjusts the voltage applied to the drive part (30) for a voltage corresponding to the pulling rate of the trigger (13). When the current running toward the drive part (30) exceeds the rated value of the drive part (30), the power supply circuit (16) automatically stops power supply to the drive part (30). On the other hand, when the output voltage of a battery (50) drops and the battery (50) is put in an overdischarge state, power supply to the drive part (30) is automatically stopped. When it is detected that the battery (50) undergoes an abnormal event, power supply to the drive part (30) is automatically stopped.
