Power Supply System - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240113546 titled 'Power Supply System

Simplified Explanation

A power supply system consists of multiple cell units connected in parallel, each containing a battery pack and a converter. The system is controlled to regulate output voltage and power, switching between voltage control and power control for different cell units at prescribed intervals.

• The power supply system is composed of multiple cell units with batteries and converters.
• A control device regulates the output voltage to match a voltage command.
• Different cell units are subjected to power control to match a power command.
• Cell units are switched between voltage control and power control periodically.

Potential Applications

The technology can be applied in various fields such as renewable energy systems, electric vehicles, and portable electronic devices.

Problems Solved

This innovation solves the problem of efficiently managing power supply systems with multiple cell units, ensuring stable output voltage and power levels.

Benefits

Original Abstract Submitted

a power supply system is composed of a plurality of cell units connected in parallel. each of the cell units includes a battery pack and a converter. a control device subjects the cell unit to voltage control such that an output voltage from the power supply system attains to a voltage command and subjects a cell unit different from the cell unit subjected to voltage control to power control such that output power from the power supply system attains to a power command, and switches a cell unit to be subjected to voltage control every prescribed period.
