Abstract
An electric work machine includes a motor, a first connector, a second connector, an energizing circuit, a manual switch, and a controller. The controller electrically disconnects the first connector from the motor based on a first voltage value below a first threshold at a start of motor rotation. The controller maintains an electrical connection of the first connector to the motor based on the first voltage value below the first threshold and equal to or greater than a second threshold during discharge of the first battery.
