1. An industrial vehicle comprising:

  • a storage battery that includes a plurality of battery cells including electrolyte and electrode plates, the battery cells being connected in series, and a detecting point, disposed between the electrode plates of adjacent battery cells, at which a voltage value for detecting a shortage of the electrolyte is detected;

    an electrolyte shortage detection unit that detects a shortage of the electrolyte in at least one of the battery cells by detecting a voltage value at the detecting point;

    an electrolyte-shortage time calculation unit that calculates an electrolyte-shortage time, which is a cumulative time of the shortage of the electrolyte detected by the electrolyte shortage detection unit when the shortage of the electrolyte continues;

    a memory unit that stores the electrolyte-shortage time calculated by the electrolyte-shortage time calculation unit;

    a time information generating unit that generates time information; and

    an output processing unit that performs output processing for attaching the time information to the electrolyte-shortage time stored in the memory unit and outputting the electrolyte-shortage time with the time information to an output unit, at a predetermined timing.
