Abstract
An electric work machine (), such as a power tool, comprises a motor (), a manipulatable part () such as a trigger switch, and a control part (). The motor is energized with electric current supplied by a battery pack (). By manipulating the manipulatable part, the control part energizes the motor. The control part also acquires information concerning the state of the battery from the battery pack, and, if appropriate based on the information obtained from the battery pack, takes measures (such as limiting a discharge current) to restrain, delay and possibly avert the performance of a protection (discharge-prohibited) operation by the battery pack.
