Innovation Solution
A module-based simulation tool separates vehicle and battery analysis, using a power profile to evaluate different designs and compare battery solutions based on drive cycles and electrical loads, while also testing actual batteries for performance validation, identifying performance-limiting components for system optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a singular battery solution is used for all vehicles, then standardization is improved, but vehicle-specific performance optimization deteriorates
Solution Approach 1:
The patent applies parameter changes by enabling the simulation tool to adjust battery parameters (capacity, chemistry, dimensions) and vehicle parameters (power demand, drive cycle, electrical loads) to optimize performance for specific vehicle applications while maintaining a standardized simulation framework. This allows the same tool to evaluate different battery solutions tailored to each vehicle's unique requirements.
2Measurement precision
If comprehensive vehicle and battery variables are considered, then optimization accuracy is improved, but design process complexity deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the design process into separate simulation modules: vehicle simulation (power demand calculation), battery simulation (performance evaluation), and integration platform (parameter combination and optimization). This modular approach manages complexity while maintaining comprehensive variable consideration through systematic data flow between modules.
Solution Approach 2:
The patent uses an integration platform as an intermediary that connects vehicle simulation and battery simulation modules. This intermediary manages the complex interactions between vehicle and battery parameters, coordinating data exchange and enabling comprehensive optimization without requiring direct complex coupling between all system components.
3Measurement precision
If actual battery testing is performed for validation, then performance prediction accuracy is improved, but testing time and resources deteriorates
Solution Approach 1:
The patent applies preliminary action by using simulation tools to evaluate and pre-screen battery solutions before physical testing. The simulation platform performs comprehensive performance evaluation under various drive cycles and operating conditions, allowing only the most promising candidates to proceed to actual battery testing, thereby reducing overall testing time and resources.

AI summary
A module-based framework evaluates designs of advanced start stop systems, particularly 12 V advanced start stop systems. The framework separates vehicle and battery analysis and uses a power profile to evaluate different designs of the vehicles and batteries. Particularly, the framework can evaluate different battery solutions and compare performances as a function of drive cycles, motor size, and electrical loads. In addition to modeling, actual batteries are tested for the same power inputs for validating performance differences. This framework identifies performance limiting components for determination of the vehicle system component optimization.
