Power Supply System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18369874 titled 'Power Supply System

Simplified Explanation

The patent application abstract describes a power supply system that includes multiple battery units connected in parallel to a load, with a control device managing the operation of each battery unit. The control device performs voltage control in one battery unit based on a voltage command, and power control in another battery unit based on a power command. It also sets a limit for changes in electric power during voltage control, and switches to voltage control in a different battery unit if the output voltage deviates significantly from the command voltage.

• The power supply system consists of multiple battery units connected in parallel to a load.
• A control device manages the operation of each battery unit, performing voltage control and power control based on commands.
• The control device sets a limit for changes in electric power during voltage control to ensure stability.
• If the output voltage deviates significantly from the command voltage, the control device switches to voltage control in a different battery unit.

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.
