摘要： A power tool includes a motor and control means for controlling the motor. The motor is capable of being driven by power supplied from a battery pack including a battery cell. The control means is configured to continue to rotate the motor even when a motor-halt signal is inputted from the battery pack. With this structure, the power tool can be used continuously without need to halt rotation of the motor, even when receiving a halt signal, such as an overdischarge detection signal or an overcurrent detection signal.

摘要： A charging apparatus (200) able to safely and reliably secure capacity is provided. The charging apparatus (200) comprises: a charging current configuration unit (70) that configures a set value for the charging current flowing to the battery (2a); a charging current controller (60) that controls the charging current on the basis of the set value configured by the charging current configuration unit (70); a cell voltage detector that detects the cell voltages applied to each cell (2b); and a voltage determining unit (2b) that determines whether or not at least one of the cell voltages detected by the cell voltage detector has exceeded a threshold voltage. If it is determined by the voltage determining unit that at least one of the cell voltages has exceeded the threshold voltage, then the charging current configuration unit (70) switches the set value to a smaller value.
