POWER SUPPLY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240266860 titled 'POWER SUPPLY SYSTEM

The battery string in this patent application is designed to allow multiple battery circuit modules to be connected in series. The drive circuit in each module transmits a gate signal to control the switch downstream, with a predetermined delay time.

• The drive circuit in each battery circuit module transmits a gate signal to control the switch downstream.
• The delay time of the gate signal can be adjusted based on the number of battery circuit modules to be operated.
• By adjusting the delay time, the frequency of operation can be controlled to prevent an increase in loss.

Potential Applications: - Energy storage systems - Electric vehicles - Renewable energy systems

Problems Solved: - Efficient control of battery circuit modules in a series configuration - Prevention of loss due to high frequency operation

Benefits: - Improved efficiency in battery management - Extended lifespan of battery systems - Enhanced control over energy storage systems

Original Abstract Submitted

the battery string is configured so that a plurality of battery circuit modules can be connected in series. the drive circuit su from the drive circuit su of the battery circuit module transmits a gate signal for on/off of the switch to the downstream drive circuit su while delaying the gate signal by a predetermined delay time td. when a particular battery circuit module (drive circuit su in fig. ) is passed through, the delay time is switched from the delay time td to the delay time tds. the delay time tds is longer than the delay time td. as a result, the period of the gate signal, which is the “delay time�the number of battery circuit modules to be operated”, can be suppressed from becoming short (the increase in frequency can be suppressed), and an increase in loss can be suppressed.
