Classification: CPC B  H | IPC B  H

Claim 19:
20. A method comprising:
conducting an electric current path in response to a manual switch of an electric powered work machine being manually operated, the electric current path connecting a power supply with a motor of the electric powered work machine;
interrupting the electric current path in response to the manual switch not being manually operated;
generating a reference voltage having a first magnitude in response to a first condition being established, the first magnitude being different from zero volts;
generating the reference voltage having a second magnitude in response to the first condition not being established, the second magnitude (i) being different from zero volts and (ii) being different from the first magnitude; and
outputting an output voltage based on the reference voltage and a measured voltage, the measured voltage being generated across a shunt resistor on the electric current path in response to an electric current flowing through the shunt resistor, and the output voltage being consistent with the reference voltage in response to the electric current not flowing through the shunt resistor.
