Title:
POWER SUPPLY APPARATUS
Document Type and Number:
Japanese Patent JP2019033636
Kind Code:
A
Abstract:
To provide a power supply apparatus capable of executing charge control of a storage battery which sets system power at a fixed value with a small number of sensors.SOLUTION: A control unit 25, when a vehicle 60 is connected with a bidirectional power conversion unit 21 in a charging mode for charging a storage battery 61, calculates system power on the basis of a detection value of a system CT sensor 71 for measuring an electric current running through a system power line of a commercial power system 40, and when system power is smaller than charging power to the storage battery 61, controls the bidirectional power conversion unit 21 with a value obtained by adding a fixed value to a value obtained by subtracting the system power from the charging power as a charging power indication value and when the system power is at least the charging power, stops charging of the storage battery 61 by the directional power conversion unit 21.SELECTED DRAWING: Figure 1
