SYSTEMS AND METHODS FOR INFLUENCING BATTERY CELL CYCLE LIFE BY VARYING COMPRESSION FORCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17846141 titled 'SYSTEMS AND METHODS FOR INFLUENCING BATTERY CELL CYCLE LIFE BY VARYING COMPRESSION FORCE

Simplified Explanation

The patent application describes a battery charging system that can influence the lifespan of battery cells by adjusting the compression force applied to them during charging.

  • The system includes a battery array, a compression device, and a control module.
  • The compression device applies a compression force to the battery array during charging events.
  • The control module is programmed to control the compression device.
  • During low charging rate conditions, a first compression force is applied.
  • During high charging rate conditions, a second, different compression force is applied.

Potential Applications

  • Electric vehicles: This technology can be used in electric vehicles to optimize the charging process and extend the lifespan of the battery cells.
  • Renewable energy storage: Battery systems used for storing renewable energy can benefit from this technology to improve their performance and longevity.
  • Portable electronics: The innovation can be applied to battery charging systems in smartphones, laptops, and other portable devices to enhance battery life.

Problems Solved

  • Battery cell degradation: By adjusting the compression force during charging, the system can help mitigate the degradation of battery cells, extending their lifespan.
  • Inefficient charging: The technology addresses the issue of inefficient charging by optimizing the compression force based on the charging rate, ensuring more effective and faster charging.

Benefits

  • Prolonged battery lifespan: By varying the compression force, the system can help increase the cycle life of battery cells, reducing the need for frequent replacements.
  • Improved charging efficiency: The technology ensures that the compression force is optimized for different charging rates, resulting in more efficient and faster charging.
  • Enhanced battery performance: By mitigating cell degradation, the system can maintain the performance and capacity of the battery cells over a longer period of time.


Original Abstract Submitted

Battery charging systems and methods are disclosed for influencing battery cell cycle life by varying a compression force applied to the battery cells during charging events. An exemplary battery charging system may include a battery array, a compression device configured to apply a compression force to the battery array during a charging event, and a control module. The control module may be programmed to control the compression device to apply a first compression force during a low charging rate condition and to apply a second, different compression force during a high charging rate condition
