1. An electrically-driven tool, comprising:
an actuator device that is configured to output kinetic energy during a predetermined stroke;
a kinetic device that is configured to generate mechanical energy for said actuator device to output as the kinetic energy, and that includes a motor and a movable component, the motor being configured to be activated to convert electric energy into the mechanical energy during the predetermined stroke, the movable component being disposed to perform a pre-arranged movement during the predetermined stroke; and
an electrically-controlled device that includes a battery to supply the electric energy to said motor, a detector switch, and a controller electrically connected to said battery and said detector switch, said detector switch being configured to output a detection signal when said movable component is detected thereby;
wherein said controller is configured to pre-store a dataset of energy provision time that includes at least one data piece of energy provision time, one of the at least one data piece signifying a predetermined time length presumed to be required by said battery to provide a predetermined amount of electric energy;
wherein said controller is configured to provide the predetermined amount of electric energy to said kinetic device to have said kinetic device perform the predetermined stroke with a predetermined load, and time a stroke time period taken by the predetermined stroke;
wherein said controller is configured to determine whether the stroke time period is greater than the predetermined time length, and output a battery abnormality signal upon determining that the stroke time period is greater than the predetermined time length; and
wherein said controller is configured to start the predetermined stroke based on a trigger signal, and to end the predetermined stroke based on the detection signal.
