EQUALIZATION CONTROL DEVICE FOR BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240136826 titled 'EQUALIZATION CONTROL DEVICE FOR BATTERY
Simplified Explanation
The patent application describes a control unit that performs equalization of charge capacities, charge rates, and voltages between two cells in a battery system to ensure balanced performance.
- The control unit monitors the difference in full charge capacities of the two cells and initiates equalization if the difference exceeds a threshold value.
- Equalization is also triggered if the difference in charge rates at full charge between the two cells exceeds a second threshold value.
- Additionally, the control unit equalizes the voltages of the two cells if their difference surpasses a third threshold value.
Potential Applications
The technology can be applied in various battery systems, such as electric vehicles, renewable energy storage systems, and portable electronic devices.
Problems Solved
1. Imbalance in charge capacities, charge rates, and voltages between cells in a battery system can lead to reduced performance and lifespan. 2. Unequal charging and discharging of cells can result in safety hazards and inefficiencies.
Benefits
1. Improved battery performance and longevity. 2. Enhanced safety by preventing overcharging or over-discharging of cells. 3. Increased efficiency in energy storage and utilization.
Potential Commercial Applications
"Balanced Battery Control Unit for Enhanced Performance and Safety"

Original Abstract Submitted
the control unit includes: when an absolute value of a difference between a full charge capacity of a 1 cell and a full charge capacity of a 2 cell is equal to or larger than a 1 threshold value, equalization is performed so that an absolute value of a difference between a charge rate of a 1 cell and a charge rate of a 2 cell at the time of full charge is less than a 2 threshold value, and when an absolute value of a difference between a voltage of a 1 cell and a voltage of a 2 cell is equal to or larger than a 3 threshold value, equalization is performed so that an absolute value of a difference between a voltage of a 1 cell and a voltage of a 2 cell becomes less than a 3 threshold value.
