Abstract
[Problem] In a control system for an electric work vehicle, a space for a size increase of other components such as a high-voltage battery is increased, and a labor for battery replacement is reduced by eliminating a need for mounting a low-voltage battery. [Solution] The control system includes a traveling motor to which power is fed from a battery via a main switch, a control device which controls an ON/OFF state of the main switch, and a first start switch connected between an output side of a DC-DC converter and the control device and is configured such that a primary side of the main switch is connected to an input side of the DC-DC converter with a second start switch interposed, and the control device is started by an output voltage of the DC-DC converter by an operation of the second start switch to an energized position. The control device turns on the main switch and maintains the state when the second start switch is operated to an energized position and the first start switch is at an operation position to the energized position.
