Battery Cell Voltage Correction for Fastening Position Errors

The patent applies preliminary action by pre-calculating compensation values for voltage measurement errors that occur at different fastening positions. A lookup table is created in advance storing correction values corresponding to various fastening positions. During actual measurement, the system simply retrieves the appropriate compensation value from the pre-prepared table and applies it, eliminating the need for complex real-time error calculation while improving measurement precision.

The patent implements feedback by using the measured voltage values along with fastening position information to determine compensation values, then applying these compensations to correct the voltage measurements. The corrected voltage values are fed back into the safety diagnosis system, allowing battery cells that were previously excluded due to measurement errors to now be properly included in safety diagnosis with accurate readings, thus improving both reliability and coverage.

The patent applies parameter changes by organizing compensation values in a lookup table indexed by fastening position parameters. Instead of storing all possible compensation scenarios, the system uses discrete position parameters as indices to retrieve appropriate compensation values. This approach maintains fast correction speed while optimizing storage requirements by only storing necessary compensation data for identified fastening positions.
