Failure Determination Apparatus for Electricity Storage

The patent segments the failure detection process into multiple independent analysis dimensions: voltage difference analysis, equalizing circuit operation time analysis, and sensor state evaluation. By dividing the detection task into separate analytical components, the system can independently evaluate each aspect and combine results to achieve accurate failure determination while maintaining operational simplicity.

The patent introduces a new dimension of analysis by incorporating equalizing circuit operation time as an additional parameter alongside voltage differences. This dimensional expansion transforms the detection from a single-threshold approach to a multi-parameter evaluation, enabling the system to distinguish between sensor failures and actual battery deterioration through comparative analysis across multiple dimensions.

The patent implements preliminary action by continuously accumulating voltage difference data and equalizing circuit operation time data during normal battery operation. This pre-collected data is stored and prepared for analysis, so when a failure determination is needed, the system can immediately retrieve and analyze the accumulated data without requiring complex real-time processing, thereby reducing operational complexity while maintaining high detection accuracy.

The patent introduces an intermediary evaluation mechanism that compares accumulated data against predetermined thresholds and evaluates sensor states indirectly through multiple measurement parameters. This intermediary layer acts as a mediator between raw data and failure determination, simplifying the overall system architecture by providing a structured intermediate analysis step that reduces the complexity of direct failure detection.

The patent applies preliminary action by continuously accumulating and pre-processing voltage difference and equalizing circuit operation time data during normal operation. This advance preparation ensures that when failure determination is required, the analysis can be performed quickly by retrieving pre-accumulated data rather than collecting it in real-time, thus reducing analysis time while maintaining multi-parameter evaluation accuracy.

The patent implements partial action by selectively analyzing the most relevant accumulated data parameters based on the specific detection need. Rather than processing all possible data continuously, the system performs targeted analysis on pre-accumulated voltage differences and equalizing circuit times that are most indicative of the suspected failure mode, reducing unnecessary computational overhead and analysis time while maintaining detection accuracy.
