Power Supply System - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097477 titled 'Power Supply System

Simplified Explanation

The patent application describes a power supply system that includes multiple battery units connected in parallel to a load, with a control device managing each battery unit's voltage and power output.

The system performs voltage control in the first battery unit based on a voltage command, and power control in the second battery unit based on a power command.
A limit value is set for changes in electric power during voltage control in the first battery unit, triggering voltage control in the second battery unit if the output voltage deviates significantly from the command voltage.

Original Abstract Submitted

a power supply system includes: a plurality of battery units connected to a load in parallel with each other; and a control device that controls each of the plurality of battery units. the control device performs voltage control (first voltage control) in accordance with a voltage command (first voltage command) in a first battery unit, and performs power control in accordance with a power command in a second battery unit. the control device sets a limit value for a change in electric power in the voltage control of the first battery unit, and when a difference between an output voltage value and a command voltage value exceeds a predetermined range, performs voltage control (second voltage control) in accordance with a voltage command (second voltage command) in the second battery unit.
