Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module structures lack the ability to automatically recognize changes in the number of lower modules connected, making it difficult for the upper controller to adapt and update module information, which limits versatility and increases system costs.
Innovation Solution
Implementing a method using Controller Area Network (CAN) communications for the upper controller to exchange messages with lower modules, recognizing additions and removals by unique ID assignment and deletion, ensuring seamless integration and management of battery modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper controller uses fixed software to store the number of lower modules, then the system structure is simple, but the adaptability to different module configurations is poor
Solution Approach 1:
The patent implements dynamic module configuration recognition by enabling the upper controller to automatically detect and adapt to changes in the number of lower modules through continuous monitoring of communication signals. The system transitions from fixed software configuration to dynamic detection, allowing the controller to adjust to different module configurations in real-time without requiring software reconfiguration.
Solution Approach 2:
The upper controller performs self-configuration by automatically recognizing and counting lower modules through communication signals. The system eliminates the need for manual configuration or pre-programmed module counts by enabling the controller to autonomously detect and adapt to the actual number of connected modules, thereby improving versatility without proportionally increasing software complexity.
2Productivity
If the upper controller manually configures module information, then the system is easy to manufacture, but the operation efficiency is low
Solution Approach 1:
The system performs preliminary configuration actions by automatically detecting and registering lower modules as they are connected to the battery pack. The upper controller proactively monitors communication signals and pre-configures module information before manual intervention is needed, thereby accelerating the recognition process and reducing operational steps.
Solution Approach 2:
The patent implements a feedback mechanism where lower modules transmit identification signals to the upper controller, which automatically processes and stores the module information. This closed-loop communication system eliminates manual configuration operations by using automated feedback from the modules themselves, significantly improving productivity while maintaining ease of operation through simple connection procedures.
3Adaptability or versatility
If the battery management system uses a platform structure independent of the number of lower modules, then the cost is reduced, but the system cannot recognize module changes
Solution Approach 1:
The patent introduces communication signals as an intermediary mechanism that enables the platform-independent battery management system to recognize module configurations. The lower modules transmit identification signals that serve as intermediaries, carrying configuration information to the upper controller without requiring the controller to have pre-programmed knowledge of specific module counts, thus maintaining platform versatility while preventing information loss.
Solution Approach 2:
The system dynamically changes operational parameters by adjusting the number of monitored communication channels and data processing parameters based on the detected number of lower modules. This allows a single platform-independent software structure to adapt to different module configurations by modifying runtime parameters rather than requiring different software versions, thereby maintaining both versatility and complete configuration awareness.

AI summary
A method for updating lower module information in a battery module structure in which an upper controller controls and manages a lower module configured of a plurality of battery modules and lower battery managers connected to each of the battery modules by communicating with each of the lower battery managers. The method includes when the lower module is additionally connected, recognizing, by the upper controller, the addition of the lower module by exchanging a message with the added lower module. The added lower module is registered by assigning a new unique ID to the added lower module by exchanging the message with the added lower module by the upper controller.
