PROBLEM TO BE SOLVED: To provide an electric work vehicle for protecting a battery from power reduction caused by unnecessary discharge accompanying leakage or the like, a battery device, and a battery monitoring device.SOLUTION: An electric work vehicle comprises: a rotary unit 10 for performing predetermined work; an electric motor 20 for supplying rotary drive force to the rotary unit; an on-vehicle battery 30 for supplying power to the electric motor; and a power supply unit 60 which converts DC power stored in the battery to desired AC current and supplies the AC current to the electric motor. The electric work vehicle further comprises a battery monitoring device 50 installed between the power supply unit and the battery which monitors current from the battery and cuts off the battery when the monitored current has exceeded a predetermined current limit value, where a plurality of current limit values are set as the current limit value and a current limit value at halt time (LimiLow) is set so as to be smaller than a current limit value at operation time (LimiHigh). |
