Battery SoH Evaluation from Charge-Command and Voltage Distributions

The patent creates a virtual copy of the charge/discharge test environment through simulation. Instead of physically stopping the system to perform actual tests, the system uses historical operational data to construct virtual test scenarios that replicate various charge/discharge conditions. This allows deterioration evaluation to proceed on a digital twin of the battery system while the physical system remains operational.

The patent performs preliminary data collection and processing during normal operation. Historical charge/discharge data, temperature data, and voltage data are continuously accumulated and pre-processed in advance. When evaluation is needed, the system can immediately conduct virtual tests using this pre-prepared data without requiring system shutdown, thus maintaining availability while enabling precise evaluation.

The patent introduces a data processing and simulation module as an intermediary between the operational system and the evaluation process. This intermediary layer takes raw operational data during continuous operation, processes it through virtual simulation models, and produces evaluation results without requiring direct intervention in the physical system. This mediator enables precise evaluation while the system continues to operate normally.

The patent replaces the mechanical/physical charge/discharge testing process with a computational simulation process. Instead of physically charging and discharging the battery to test its deterioration (which would require stopping the system), the system uses mathematical models and computational algorithms to simulate these processes and predict deterioration based on historical data patterns.
