Power distribution system

Abstract

Provided is a power distribution system for improving reliability of power supply to the load in a case where a bidirectional DC/DC converter is connected to one power supply when making a power supply redundant, connecting a first battery and a second battery so as to supply power to a load, including: a bidirectional DC/DC converter detecting an output of the first battery and an output of the second battery, and controlling charge and discharge operation of the second battery: and a control unit detecting the output voltage of the first battery and the output voltage of the second battery, and determining from which one of the first battery and the second battery power should be supplied to the load based on detection results by the control unit and the bidirectional DC/DC converter.

Dependencies are inferred from the claim text.
