Solution Overview

Problem

Existing battery management systems face challenges in efficiently addressing multiple slave controllers, necessitating improved methods for managing and controlling these controllers to enhance operability and efficiency.

Innovation Solution

A battery management system incorporating a master control module, selection modules, and N slave control modules, allowing for both automatic and manual addressing modes through a selection module that switches between different connection paths, enabling efficient addressing even when individual slave controllers fail.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sequential addressing of all slave controllers is used, then systematic control is achieved, but addressing efficiency deteriorates when individual controllers fail

Engineering Contradiction:
Improveaddressing efficiencyVSAvoidaddressing mode complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system dynamically switches between sequential addressing mode and direct addressing mode based on operational needs. The selection module enables the master controller to choose different addressing pathways, making the system flexible rather than fixed in its addressing approach.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The selection module acts as an intermediary component between the master controller and slave controllers. It receives selecting signals from the master controller and routes addressing signals accordingly, either sequentially through all slave controllers or directly to a specific one, thereby mediating the addressing process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple addressing modes are provided, then operability is improved, but system complexity increases

Engineering Contradiction:
ImproveoperabilityVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The selection module serves multiple functions: it routes addressing signals in sequential mode, routes addressing signals in direct mode, and responds to selecting signals from the master controller. This multi-functionality consolidates what could be separate systems into a single versatile component.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system pre-configures multiple addressing pathways and the selection module is ready to switch between them based on the master controller's selecting signals. This preliminary preparation of multiple modes allows rapid adaptation without adding complex real-time decision-making logic.

Inventive Principle:
Principle #10Preliminary action
