Claims7
A work vehicle comprising:
- an electric actuator;
- a battery configured to supply drive power to the electric actuator;
- a charging section via which the battery is chargeable from a power source external to a vehicle body;
- a discharge operation apparatus configured to cause the battery to discharge during charging of the battery;
- a hydraulic pump connected to a hydraulic actuator via an operating oil path and configured to supply hydraulic oil to the hydraulic actuator;
- an operating valve provided in the operating oil path and configured to control the hydraulic actuator;
- an electric motor configured to drive the hydraulic pump;
- an operating valve position detection mechanism configured to detect that the operating valve is in a neutral position for stopping the hydraulic actuator;
- a power device connected to the battery;
- and
- a discharge circuit extending between the battery and the power device,
- wherein the discharge circuit includes a discharge switch capable of switching between a connected state and a disconnected state between the battery and the power device, and
- wherein the discharge operation apparatus causes the battery to discharge by connecting the battery to the electric motor such that power is supplied to the electric motor from the battery when the operating valve is in a neutral position for stopping the hydraulic actuator.
