More Information
Summary:A composite battery set of a power tool, comprising a battery, a non-polarity ultracapacitor, a switch, a motor, etc. The ultracapacitor is a non-polarity ultracapacitor, and the power released by the fully charged battery at a high discharge rate is utilized to drive a motor. As such, a switch is used to switch and connect the non-polarity ultracapacitor to the different polarities of the motor, thus achieving the switching of the rotation directions of the motor.
