Battery Pack ID Assignment for Variable Pack Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems face challenges in efficiently managing battery packs with varying numbers without requiring modifications to the controller, and there is a need for rapid assignment and management of identification numbers.
Innovation Solution
A method and system that initializes battery packs into a state where identification numbers can be set, allowing each pack to determine its number based on signals from preceding packs, and generates and outputs signals with additional pulses to establish unique identification numbers, enabling batch setting and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a controller is individually set according to the number of battery packs, then the battery management can be accurately configured, but the device complexity and setup time increase when the number of battery packs varies
Solution Approach 1:
Each battery pack automatically determines its own identification number by counting the number of low-level signals received from the communication bus during initialization. This self-configuration mechanism eliminates the need for manual controller setup according to battery pack numbers, allowing the system to adapt automatically when battery packs are added or removed.
2Productivity
If identification numbers are assigned manually or through complex initialization, then unique identification can be achieved, but the time required for system setup and reconfiguration increases
Solution Approach 1:
The battery packs perform preliminary actions during initialization by automatically counting low-level signals from the communication bus to determine their identification numbers before full system operation begins. This preliminary self-configuration enables rapid system setup and reconfiguration without manual intervention or complex initialization procedures.
