MANAGEMENT METHOD FOR CHARGING SECONDARY BATTERIES OF WORK VEHICLES, AND SYSTEM FOR CHARGING SECONDARY BATTERIES OF WORK VEHICLES

摘要

The management method for charging secondary batteries of work vehicles includes: a step of acquiring remaining battery levels of secondary batteries which supply powers respectively to work vehicles; a step of calculating estimated power consumptions of the work vehicles for a predetermined time from the current time; a step of calculating an index value for determining a priority order for replacing the secondary batteries of the work vehicles by referring to differences between the remaining battery levels of the secondary batteries and the estimated power consumptions; and a step of outputting a return command to one of the work vehicles based on the index value and the acceptable charge amounts by which the secondary batteries can be respectively charged.
