Abstract

A system for managing refueling and charging of a plug-in hybrid vehicle is provided to prevent charging from being performed simultaneously with refueling to prevent accidents attributable to the occurrence of gas fumes and static electricity. The system includes a plurality of input units configured to receive instructions for refueling and charging a battery. A fueling/charging controller is configured to determine whether a process for refueling and a process for charging the battery are progressing and to start a process that corresponds to the instruction input from any one of the plurality of input units when neither the process for refueling nor the process for charging the battery is progressing.
