Battery Module Connector Diagnostics for BMS Setting Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and changing the state of battery modules in energy storage systems are inefficient, requiring separate communication equipment and power supplies, leading to high costs and reduced portability, and involve cumbersome programming for each use case.
Innovation Solution
A device with a connection unit, communication unit, control unit, diagnosis unit, memory unit, and change data input unit that connects to a battery module's connector to transmit and receive data, diagnose the battery state, and change settings in the battery management system, eliminating the need for separate communication equipment and simplifying programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication equipment and power supplies are used for battery diagnosis, then reliable data transmission is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines communication and power supply functions into a single connector interface. The connector simultaneously provides power transmission lines and communication signal lines, eliminating the need for separate communication equipment and power supplies. This merging approach maintains reliable data transmission while significantly reducing device complexity and cost.
Solution Approach 2:
The connector is designed with multi-functionality, serving both as a power supply interface and a communication interface. By making the connector universal for both power and data functions, the system eliminates redundant equipment while ensuring reliable operation. The connector handles multiple tasks (power delivery, data transmission, status monitoring) through a single integrated interface.
2Power
If separate power supply devices and cables are provided for external devices, then sufficient power is supplied, but portability is reduced
Solution Approach 1:
The power supply and communication functions are merged into a single connector connection. The battery module's connector provides both power and data transmission simultaneously, eliminating the need for separate power supply devices and cables. This integration significantly improves portability while maintaining sufficient power supply capability for external devices.
3Adaptability or versatility
If programs are provided for each use case of battery module, then specific use requirements are met, but cost and time for program management increase
Solution Approach 1:
The system dynamically adapts to different use cases through runtime configuration rather than requiring separate static programs for each application. The BMS can be configured with different parameter sets and operating modes that are loaded and activated as needed, allowing the same hardware platform to serve multiple purposes without time-consuming program installation and management.
Solution Approach 2:
Different use cases are accommodated by changing operational parameters and configuration data rather than requiring different programs. The system allows dynamic adjustment of voltage thresholds, current limits, temperature parameters, and other operational settings to match different application requirements, eliminating the need for multiple specialized programs and reducing management overhead.
