Electric Work Vehicle and Work Vehicle

A work vehicle comprising:

• an energy storage portion configured to store energy;
• a prime mover configured to generate motive power by receiving supply of the energy;
• a traveling device configured to operate by the motive power;
• a work power output portion configured to output the motive power to be supplied to a working device configured to perform work;
• a travel transmission system configured to transmit the motive power from the prime mover to the traveling device;
• a work transmission system configured to transmit the motive power from the prime mover to the work power output portion;
• a remaining amount detection unit configured to detect a remaining amount of the energy stored in the energy storage unit;
• and
• a transmission control unit configured to control transmission states of the travel transmission system and the work transmission system, and
• wherein the transmission control unit performs conservation control for stopping output of the motive power from the work power output portion in response to the remaining amount detection unit detecting that the remaining amount is less than or equal to a predetermined reference remaining amount.

• and
• a transmission control unit configured to control transmission states of the travel transmission system and the work transmission system, and
• wherein the travel transmission system comprises a continuously variable transmission configured to change a speed of the motive power input to a hydraulic pump and output the resulting motive power from a hydraulic motor, and
• wherein the transmission control unit performs conservation control for reducing the motive power input to the hydraulic pump in response to the remaining amount detection unit detecting that the remaining amount is less than or equal to a predetermined reference remaining amount.
