Hybrid electric vehicle management device, hybrid electric vehicle management method, and hybrid electric vehicle management system

A hybrid electric vehicle management device configured to manage a hybrid electric vehicle that includes an internal combustion engine and that is configured to perform either or both of external charging and external discharging, includes a processor. The processor is configured to acquire vehicle information of a first hybrid electric vehicle and vehicle information of a second hybrid electric vehicle. The vehicle information includes information on the amount of fuel remaining in the hybrid electric vehicle. The processor selects, based on the vehicle information, the first hybrid electric vehicle as a hybrid electric vehicle to which either or both of the external charging and the external discharging is to be requested. The amount of fuel remaining in the first hybrid electric vehicle is larger than the amount of fuel remaining in the second hybrid electric vehicle.
