<P>PROBLEM TO BE SOLVED: To provide a safe electric working vehicle capable of consuming regenerative electric power without using a discharging load resistance and preventing an actuator from deriving harm even when the same occasion occurs. <P>SOLUTION: The electric working vehicle includes: a running motor 30 for driving running wheels to run; a blade motor 70 for rotating a mowing blade 80; a battery 50; a running motor controller (conversion device) 60 for feeding required electric power to the motor for running; a blade motor controller (conversion device) 65 for feeding required electric power to the motor for a blade; a CPU 603 for controlling the controller; and a CPU 653 for controlling the controller. Herein, the running motor controller can operate in a regenerative mode, and the blade motor controller is controlled so that regenerative electric power when the running motor is in a regenerative operation mode is fed to the blade motor to be consumed, depending on a charged state of the battery, and when the blade is stopped, the regenerative electric power is consumed without rotating the blade motor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
