Battery Diagnosis Table Synchronization for Misdiagnosis Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery diagnosing systems face challenges in accurately diagnosing battery state information due to limitations in updating diagnosis tables and storing diagnosis codes, leading to potential misdiagnosis and loss of historical data, especially when internal memory is damaged.
Innovation Solution
A battery diagnosing system and method that updates a diagnosis table through communication between a central server and a battery diagnosing apparatus, allowing for accurate diagnosis code verification and backup of battery state information, enabling reliable and accurate diagnosis even if the diagnosing apparatus is damaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only internal memory is used to store diagnosis codes and battery state information, then the device structure remains simple, but the reliability is reduced because data is lost when memory is damaged
Solution Approach 1:
The patent introduces an external server as an intermediary to store backup diagnosis codes and battery state information. The server acts as a mediator between multiple diagnosing apparatuses and provides centralized data storage, preventing data loss when individual device memories are damaged.
Solution Approach 2:
The patent changes the storage location parameter from local-only (internal memory) to distributed (local memory plus external server). This parameter change allows data to be preserved both locally and remotely, improving reliability without significantly increasing device complexity.
2Measurement precision
If diagnosis tables are not updated, then the device complexity remains low, but the measurement precision deteriorates due to misdiagnosis
Solution Approach 1:
The patent implements a feedback mechanism where the diagnosing apparatus transmits diagnosis codes and battery state information to the server. The server compares these with its own diagnosis results and feeds back correction information when misdiagnosis is detected, enabling continuous improvement of diagnosis accuracy.
Solution Approach 2:
The server pre-stores accurate diagnosis codes and battery state information in its diagnosis table before actual diagnosis occurs. When a diagnosing apparatus needs updating, the server provides the corrected diagnosis table in advance, allowing the apparatus to update its local table without real-time computation during diagnosis.
3Reliability
If historical diagnosis data is not backed up externally, then the loss of information is minimized in terms of storage resources, but the reliability is reduced when the diagnosing apparatus is damaged
Solution Approach 1:
The patent segments the data storage function between local memory (for immediate access) and external server storage (for backup and historical records). This segmentation allows the system to maintain a complete copy of critical data in two separate locations, ensuring recovery reliability without requiring excessive local storage capacity.
Data Source
AI summary
The present disclosure is directed to providing a battery diagnosing system and method, which updates a diagnosis table of a battery diagnosing apparatus by communication between a central server and the battery diagnosing apparatus, and stores battery state information and a diagnosis code as a backup. According to an aspect of the present disclosure, since the diagnosis table stored in the battery diagnosing apparatus may be updated to a latest state, the battery state may be diagnosed more accurately. In addition, according to an aspect of the present disclosure, since the central server determines whether the diagnosis code generated by the battery diagnosing apparatus is misdiagnosed, the battery state may be diagnosed more accurately and reliably.
