CHARGING SYSTEM AND CHARGING METHOD

摘要

A charging system includes at least one facility connected to a feeder of a contract power source; and a charger connected to the feeder, wherein charging power is output to charge an electrical storage device, such as a battery, by an operation of a power converter in the charger. The charger stores power consumption values of facilities and a rated power value for a power that the charger can output within the range of contract power. A charging power computing section computes charging power by subtracting the total value of the power consumption values of facilities in operation from the rated power value. A power converter charges a battery based on the computed charging power.

1. A charging system, comprising:
a facility connected to a feeder of a contract power source; and a charger to charge an electrical storage device, the charger connected to the feeder and including
a power consumption storage section storing a power consumption value of the facility,a rated power storage section storing a rated power value, which is a value of a rated power that the charger can output within a range of the contract power,a charging power computing section that computes a computed charging power by subtracting the stored power consumption value of the facility upon the charger determining that the facility is in operation, from the rated power value, anda power converter that receives the computed charging power as a command signal and outputs power based on the command signal to thereby charge the electrical storage device.
