Abstract
An electric powered work machine according to one aspect of the present disclosure includes: a tool; a motor; a manual switch; an electric current path; a shunt resistor; a reference voltage generation circuit; and an electric current measurement circuit. The reference voltage generation circuit (i) generates a reference voltage having a first magnitude in response to a first condition being established, and (ii) generates the reference voltage having a second magnitude in response to the first condition not being established. The electric current measurement circuit (i) receives the reference voltage and a measured voltage, and (ii) outputs an output voltage based on the reference voltage and the measured voltage.
