Electric work vehicle
An electric work vehicle includes a travel device; a first electric motor configured to drive the travel device; a second electric motor configured to drive a pump; a battery configured to supply electric power to the first electric motor; a charging determination section configured to determine whether or not charging of the battery is needed; and a control device configured to control the first electric motor. The control device includes a regeneration control section configured to control regenerated power generated by the first electric motor, and in response to the charging determination section determining that charging of the battery is not needed, the regeneration control section performs control to supply the regenerated power from the first electric motor to the second electric motor.
1 . An electric work vehicle, comprising:
a travel device;
a first electric motor configured to drive the travel device;
a second electric motor configured to drive a pump;
a battery configured to supply electric power to the first electric motor;
a charging determination section configured to determine whether or not charging of the battery is needed;
a control device configured to control the first electric motor;
a brake operation tool; and
a brake operation detection section configured to detect an operation of the brake operation tool,
wherein the control device comprises a regeneration control section configured to control regenerated power generated by the first electric motor,
wherein in response to the charging determination section determining that charging of the battery is not needed, the regeneration control section performs control to supply the regenerated power from the first electric motor to the second electric motor,
wherein if the brake operation detection section detects the operation of the brake operation tool, the control device stops supply of electric power to the first electric motor and makes the first electric motor perform regeneration braking control to generate regenerated power, and
wherein the charging determination section detects an output voltage of the battery, and if it is determined that the output voltage exceeds a reference voltage value, the charging determination section determines that charging of the battery is not needed.
2 . The electric work vehicle according to claim 1 ,
wherein the pump is a hydraulic pump configured to pump oil in an oil circulation circuit in which an oil cooler is provided, and
wherein the second electric motor is an electric motor configured to drive the hydraulic pump.
3 . The electric work vehicle according to claim 1 ,
wherein the pump is a water pump configured to pump cooling water in a cooling water passage in which a radiator is provided, and
wherein the second electric motor is an electric motor configured to drive the water pump.
