Innovation Solution
A computer-implemented method generates a central battery configuration, allowing for the derivation of software and test cases, which simplifies software generation and testing by predetermining a fundamental topology and using markup language to represent battery components and their relationships, enabling easy replacement and extension of components with backward compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery management systems are designed to accommodate different battery component configurations, then the system becomes more adaptable to various customer requirements and installation spaces, but the software configuration effort and testing complexity increase significantly
Solution Approach 1:
The patent applies parameter changes by using a centralized configuration file (e.g., XML) that stores battery system parameters such as number of battery cells, cell types, sensor configurations, and communication network topology. By changing parameters in this central configuration file, the software can adapt to different battery configurations without requiring complex manual reconfiguration or recompilation, thus resolving the contradiction between adaptability and configuration complexity
Solution Approach 2:
The patent implements universality by creating a universal software platform that can manage multiple battery configurations through a single codebase. The centralized configuration approach allows one software system to serve multiple battery types and configurations, eliminating the need for separate software versions for each configuration and reducing overall system complexity
2Adaptability or versatility
If multiple battery component combinations are supported, then the system meets diverse customer requirements, but the testing process becomes more complicated and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-defining all possible battery configurations and their corresponding test cases in the centralized configuration file before actual deployment. Test cases are automatically generated based on the configuration parameters, allowing comprehensive testing to be performed systematically without manual test case creation for each configuration, thus reducing testing time while maintaining support for multiple combinations
Solution Approach 2:
The patent uses copying by generating test cases automatically from template configurations. Once a configuration and its test cases are defined, they can be copied and adapted to other configurations by simply changing parameters in the central configuration file, eliminating the need to manually create separate test suites for each battery combination and significantly reducing testing time
3Manufacturing precision
If software is customized for each specific battery configuration, then the software fits the specific application perfectly, but any component replacement or renewal requires extensive software changes
Solution Approach 1:
The patent applies segmentation by separating the battery configuration-specific parameters from the core software logic. The configuration file divides the system into modular components (battery cells, sensors, communication networks) with independently configurable parameters. This allows the core software to remain unchanged while only the configuration file needs to be updated when components are replaced, achieving both application precision and ease of maintenance
4Reliability
If comprehensive testing is performed for all battery management systems, then system reliability and safety are ensured, but the testing complexity increases due to varying configurations
Solution Approach 1:
The patent uses copying by creating test cases from standardized templates that can be automatically instantiated for different battery configurations. The same test case template can be copied and adapted to various configurations by parameter substitution, ensuring comprehensive reliability testing across all configurations without manually designing separate complex test procedures for each one
