Electric work vehicle
An electric work vehicle includes: an electric motor unit including a plurality of motors (21, 22, and 130); a motor control unit (50) that adjusts electric power from a battery (20) and supplies the adjusted electric power to the electric motor unit by controlling an inverter (4); a charge control section (53) that controls charging and discharging of the battery (20); a battery state detection device (9) that detects a state of the battery (20) including a rate of charge; and a regenerative electric power detection device (6) that detects a generation of regenerative electric power. When the rate of charge is in a margin region that is set between an overcharge region and a charge/discharge region, and when regenerative electric power is generated, the motor control unit (50) supplies the regenerative electric power to a motor that is not in operation, and provides a non-rotation current instruction to the inverter (4), the non-rotation current instruction being an instruction for generating a magnetic flux that does not cause the motor to rotate by using vector control.
