POWER FEEDING MANAGEMENT SYSTEM AND ON-VEHICLE APPARATUS

A power feeding management system includes a management apparatus and a plurality of on-vehicle apparatuses. The management apparatus communicates with the on-vehicle apparatuses of first and second vehicles to assist the first and second vehicles with first inter-vehicle power feeding to the first vehicle from the second vehicle. The management apparatus decides a price on the power-receiver side of the first inter-vehicle power feeding on the basis of a common power price and an amount of fed power in the first inter-vehicle power feeding. The management apparatus decides a return on the power-sender side of the first inter-vehicle power feeding on the basis of the amount of fed power in the first inter-vehicle power feeding and a power price for external charging carried out by the second vehicle before the first inter-vehicle power feeding.
