Solution Overview

Problem

Current battery management systems do not consider the correlation between measurement and diagnosis steps, leading to inefficient execution sequences for battery management items.

Innovation Solution

An identification code allocating device and sequencing device that allocate characteristic, cycle, and dependency identification codes to determine an optimal execution sequence for battery management items based on their characteristics, cycles, and dependency relationships, ensuring proper sequencing of battery state measurement and diagnosis tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If battery management items are executed sequentially based on simple predetermined conditions, then the system operation is simple, but the execution efficiency and reliability are low due to ignoring correlation and dependency relationships

Engineering Contradiction:
Improveexecution efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the parameter representation by introducing identification codes (first identification code, second identification code, third identification code) that encode execution cycles and dependency relationships. This allows the system to efficiently represent and process complex battery management item relationships without proportionally increasing system complexity, thereby improving execution efficiency while maintaining manageable system complexity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If battery management items are executed without considering dependency relationships, then the execution sequence is simple, but the measurement and diagnosis reliability are reduced

Engineering Contradiction:
Improvemeasurement and diagnosis reliabilityVSAvoidsequencing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-establishing identification codes that represent dependency relationships and execution cycles before the actual battery management execution. The first identification code representing execution cycle information and the second identification code representing dependency relationships are prepared in advance, allowing the system to reliably determine the correct execution sequence without complex real-time analysis, thus improving reliability while controlling sequencing complexity.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If all battery management items are executed in every cycle, then no items are missed, but the energy consumption and execution time increase

Engineering Contradiction:
Improvecompleteness of battery managementVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by using the first identification code to represent execution cycle information, which allows different battery management items to be executed at different cycles rather than all items in every cycle. This ensures that necessary items are executed at appropriate intervals while avoiding unnecessary executions, thus maintaining completeness of battery management while reducing energy consumption and execution time.

Inventive Principle:
Principle #19Periodic action
