Claims

[Scope of Claim for Utility Model Registration] (1) A power supply device having a battery and a charger for charging the battery, a travel/cargo handling device having a travel circuit with a travel motor and a cargo handling circuit with a cargo handling motor, and a hydraulic cylinder for lifting/lowering. a hydraulic system having;
A microcomputer that takes in the voltage and current of the battery, motor current of the travel motor and cargo handling motor, and oil pressure of the hydraulic system through the input/output circuit, and an input panel/display device that gives charging commands and display specification selection commands to this microcomputer. The microcomputer executes a charging control program, a travel/cargo handling control program, and an elevation control program to control the power supply device, the travel/cargo handling device, and the hydraulic device, and also executes a display control program. A control device for a battery cargo handling vehicle, characterized in that the control device controls sending of display data to the input panel/display device. (2) The input panel and display device includes a battery charger operating status display lamp row that displays the battery charging method, a battery remaining capacity display lamp, a specification display lamp column, a numerical specification numerical display, a display specification changeover switch, and 2. The control device for a battery cargo handling vehicle according to claim 1, further comprising a charging command switch on one panel.
