Abstract

A state display section of a work vehicle is configured to display whether an electricity storage apparatus is in an electricity charging or discharging state. A state determination unit is configured to determine the state to be displayed on the state display section on the basis of a parameter corresponding to electricity supplied to or discharged from the electricity storage apparatus. The state determination unit is configured to change a threshold for a parameter for determining if the state to be displayed on the state display section is to be set to the charging state (discharging state) based on whether or not the state displayed on the state display section most recently is the charging state (discharging state). Until a predetermined first time period elapses, the state determination section is configured to determine the state after the change as the state to be displayed on the state display section.
