Battery Capacity Gauging by Temperature and Internal Impedance

The patent applies parameter changes by switching between different gauging algorithms based on temperature conditions. When temperature is above the threshold, the TI gauging technique is used; when temperature is below the threshold, an alternative algorithm considering low-temperature characteristics is employed. This dynamic parameter adjustment resolves the contradiction by adapting the measurement method to temperature conditions, maintaining accuracy across different thermal environments.

The patent implements dynamics by making the gauging algorithm selection dynamic rather than static. The system continuously monitors temperature and dynamically switches between gauging methods based on whether the temperature meets the predetermined condition. This dynamic adaptation ensures reliable and accurate discharge-capacity estimation regardless of temperature variations, resolving the reliability-accuracy contradiction.

The patent applies segmentation by dividing the temperature range into different segments and assigning appropriate gauging algorithms to each segment. The temperature threshold creates a clear segmentation point: above-threshold temperatures use one algorithm, below-threshold temperatures use another. This segmentation maintains system precision across different conditions while keeping the control logic relatively simple through clear conditional boundaries.

The patent introduces an intermediary mechanism (temperature threshold judgment) that mediates between the simple single-algorithm approach and the complex multi-algorithm approach. The threshold-based conditional logic acts as an intermediary that selectively activates appropriate algorithms without requiring complex decision-making structures, thus maintaining measurement precision while avoiding excessive system complexity.
