  • Publication number: 20240339858
    Abstract: In a system for setting current capacity of a charging cable for supply of battery power from one electric vehicle to another electric vehicle, a discharge controller is provided in a supply vehicle to discharge a battery of the supply vehicle to supply battery power to a target vehicle. A charge controller is provided in the target vehicle to charge a battery of the target vehicle with battery power supplied from the supply vehicle. A charging cable part electrically connects the supply vehicle and the target vehicle. The discharge controller is configured to perform control so that a discharging current of the charging cable part is set by detecting an allowable charging current of the charging cable part connected to the supply vehicle and comparing the allowable charging current with a predetermined maximum current outputtable from the supply vehicle.
