- a charger that is connectable to an external power source;
- a battery;
- a sensor detecting charging current to the battery;
- a drive unit hydraulically operated by electric power supplied from at least one of the charger and the battery;
- a controller;
- a display unit;
- a battery management system monitoring both of the charger and the battery in a state of driving by connection to the external power source after receiving a valid signal for driving by connection to the external power source from the controller, the valid signal indicating that the external power source can be used;
- and
- a switch connection to the external power source for operation of the working vehicle,
- wherein the battery management system is configured to control the working vehicle to be switched to the driving by connection to the external power source when the switch is turned on after the charger is connected to the external power source and the valid signal for driving by connected to the external power source is received from the controller, and
- the battery management system is configured to control the working vehicle to be switched to the driving by connection to the external power source when the charger is connected to the external power source after the switch is turned on and the valid signal for driving by connection to the external power source is received from the controller.
