Abstract:
An industrial vehicle includes: a key-on signal detection unit that detects whether or not a key switch is in a key-on state; an under-charging signal detection unit that detects whether or not a storage battery is being charged; an operating time calculation unit that calculates a time, which is in the key-on state and in which charging is not performed, as an operating time; and an output unit that outputs the operating time.
