REDUNDANT POWER SUPPLY CONTROL DEVICE AND CONTROL METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240213791 titled 'REDUNDANT POWER SUPPLY CONTROL DEVICE AND CONTROL METHOD

The patent application describes a redundant power supply control device that manages a sub-battery capable of serving as a backup for the main battery. The control device consists of an acquisition unit, an estimation unit, and a determination unit.

  • The acquisition unit collects voltage and current values from the sub-battery.
  • The estimation unit calculates the storage rate of the sub-battery through current integration.
  • The determination unit assesses whether the sub-battery can effectively back up the main battery by comparing internal resistance values.

Key Features and Innovation:

  • Monitoring and controlling a sub-battery for backup power supply.
  • Estimating storage rate and internal resistance values for the sub-battery.
  • Determining the feasibility of using the sub-battery as a backup based on resistance values.

Potential Applications:

  • Uninterrupted power supply systems.
  • Emergency backup systems for critical equipment.
  • Redundant power solutions for data centers and telecommunications.

Problems Solved:

  • Ensuring reliable backup power in case of main battery failure.
  • Optimizing the use of sub-batteries for backup purposes.
  • Enhancing overall system resilience and reliability.

Benefits:

  • Increased system reliability and uptime.
  • Improved contingency planning for power outages.
  • Enhanced performance of critical equipment during emergencies.

Commercial Applications:

  • Title: "Redundant Power Supply Control Device for Enhanced Reliability"
  • Potential commercial uses in industries requiring continuous power supply.
  • Market implications in sectors where downtime can lead to significant losses.

Questions about Redundant Power Supply Control Device: 1. How does the estimation unit calculate the storage rate of the sub-battery? 

  - The estimation unit estimates the storage rate through current integration, analyzing the flow of current over time.

2. What are the key factors considered by the determination unit when assessing the feasibility of using the sub-battery as a backup? 

  - The determination unit compares the internal resistance values of the sub-battery to determine its capability as a backup power source.


Original Abstract Submitted

a redundant power supply control device controls a sub-battery capable of backing up the main battery. the control device includes an acquisition unit, an estimation unit, and a determination unit. the acquisition unit obtains a voltage value and a current value of the sub-battery. the estimation unit estimates the storage rate of the sub-battery by current integration. the determination unit determines whether the sub-battery can be backed up. the determination unit calculates a first resistance value that is an internal resistance value of the sub-battery estimated based on the measured voltage value and the measured current value, and calculates a second resistance value that is an internal resistance value of the sub- battery estimated based on the estimated voltage value and the measured current value. the determination unit determines whether the sub-battery can be backed up based on the larger one of the first resistance value and the second resistance value.
