First Claim
1. A power management system for performing power management on a management subject apparatus that includes a charging unit for charging a storage apparatus installed in a vehicle, the system comprising:
- a detection unit that detects a power supplied to the management subject apparatus;
an adjustment unit that adjusts a charging power charged to the vehicle from the charging unit; and
a control unit that determines an allowable power that can be supplied to the vehicle from the charging unit, notifies the vehicle of the allowable power, and controls the adjustment unit such that a power transmitted to the vehicle is reduced when it is determined that a response to the notification of the allowable power is not received based on the detected power supplied to the management subject apparatus by a detection unit.

Abstract
A power management system is a system for performing power management on a management subject apparatus that includes a charging unit for charging a storage apparatus installed in a vehicle. The power management system includes: a detection unit that detects a power consumed by the management subject apparatus; an adjustment unit that adjusts a charging power charged to the vehicle from the charging unit; and a control unit that controls the adjustment unit. The control unit determines an allowable power that can be supplied to the vehicle from the charging unit, notifies the vehicle of the allowable power, and controls the adjustment unit such that a power transmitted to the vehicle is reduced when a response to the notification of the allowable power is not received. With the system according to the invention, restrictions on charging subject vehicles can be alleviated without increasing a charging capacity of a charging facility.
