Battery Sensor Correction for Aging Measurement Accuracy

The patent applies preliminary action by pre-determining and storing assignment rules that map influencing parameter values to correction factors before the battery sensor is installed. This allows the system to compensate for aging effects from the start of operation without requiring time-consuming pre-aging processes, thus improving measurement accuracy while avoiding the time and cost penalties of traditional pre-aging methods.

The patent replaces the mechanical/physical pre-aging process with an information-based system. Instead of physically stressing components before installation, the system uses detection devices to measure influencing parameters and applies correction factors from stored assignment rules. This substitution eliminates the need for expensive pre-aging equipment and processes while maintaining measurement accuracy.

The patent changes the approach from selecting components with tight physical tolerances to using parameter-based correction. The system detects influencing parameters (such as temperature, humidity, mechanical stress) and applies correction factors based on these parameters. This allows the use of components with standard tolerances while achieving high measurement accuracy through dynamic compensation, thereby reducing manufacturing costs.

The patent implements self-service by enabling the battery sensor to automatically compensate for its own aging effects. The detection devices monitor influencing parameters, and the evaluation circuit automatically applies correction factors from stored assignment rules. This self-compensation mechanism maintains measurement accuracy over time without requiring external calibration or complex additional hardware, achieving a balance between device complexity and measurement precision.
