Battery Pack Energy Optimization via Cell Selection

The patent removes cells with abnormally low charge capacity from the series connection. By extracting these problematic cells from the battery pack configuration, the system eliminates the bottleneck that limits total energy capacity and prevents uneven charging/discharging of remaining cells, thereby resolving the contradiction between maximizing total capacity and maintaining uniform cell performance.

The patent changes the operational parameters of remaining battery cells by adjusting their charge/discharge current limits and voltage thresholds. This parameter adjustment allows the system to abandon low-capacity cells and increase total energy capacity while simultaneously reducing the stress on remaining cells through optimized current management and protective control strategies.

The patent replaces complex mechanical monitoring and management systems with an electronic control system that uses computational algorithms to monitor cell voltages, estimate charge capacities, and determine optimal cell configurations. This substitution of electronic intelligence for mechanical complexity achieves maximum energy utilization through automated cell assessment and configuration optimization without requiring cumbersome physical management infrastructure.
