ABNORMAL CELL DETECTION METHOD, ABNORMAL CELL DETECTION DEVICE, AND BATTERY PACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18237645 titled 'ABNORMAL CELL DETECTION METHOD, ABNORMAL CELL DETECTION DEVICE, AND BATTERY PACK
Simplified Explanation
The patent application describes a method for detecting abnormal cells in a battery pack with multiple cells by monitoring discharge rates and setting threshold values for detection.
- Obtaining discharge rates for each cell during rest periods
- Prohibiting cell balancing if a cell exceeds a threshold discharge rate
- Detecting abnormal cells based on discharge rates during a cell balancing prohibition state
Potential Applications
The technology can be applied in electric vehicles, energy storage systems, and portable electronic devices to ensure the safety and performance of battery packs.
Problems Solved
1. Early detection of abnormal cells can prevent potential safety hazards such as overheating or fires. 2. Optimizing the performance and lifespan of battery packs by identifying and addressing issues promptly.
Benefits

Original Abstract Submitted
An abnormal cell detection method of a battery pack including a plurality of cells, the method including obtaining a first plurality of discharge rates for each cell during a first rest period in a cell balancing state, prohibiting a cell balancing of the plurality of cells if a first cell having a first discharge rate greater than or equal to a first threshold value is detected, obtaining a second plurality of discharge rates during a second rest period for each of the plurality of cells in a cell balancing prohibition state, and detecting an abnormal cell having a second discharge rate greater than or equal to a second threshold value.
