POWER MANAGEMENT DEVICE FOR VEHICLE

The present invention is capable of decreasing the amount of energy of a vehicle consumed by a vehicle-mounted power storage device before the power storage device selectively supplies and receives electric power with respect to an external power source device. A power management device for vehicles, which is employed in the vehicle including the vehicle-mounted power storage device that selectively supplies and receives the electric power with respect to the external power source device, includes a communication control section that performs interactive communication to selectively supply and receive the electric power with respect to the external power source device and a supplying/receiving control section that controls suppling/ receiving of the electric power by the vehicle-mounted power storage device. The supplying/receiving control section is switchable between a great power state and a decreased state in which the power consumption amount is smaller than in the great power state. When the condition that the supplying/receiving control section is in the great power state is satisfied, control of the supplying/receiving of the electric power is allowed. If the supplying/receiving control section is in the decreased state before the vehicle-mounted power storage device and the external power source device selectively supply and receive the electric power with respect to each other, the communication control section performs the interactive communication.
