EV Power Adjustment by Vehicle Grouping for Battery Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to optimally manage electric power demand and supply in smart grids using electric vehicles, as they fail to account for the varying characteristics and needs of different types of electric vehicles, leading to battery deterioration and inefficient power sharing.
Innovation Solution
An electric power adjusting device that classifies electric vehicles into groups based on predetermined characteristics, such as battery type, capacity, and performance, and adjusts charging and discharging burdens to optimize power demand sharing and prevent battery deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electric vehicles are managed as a single group without classification, then the management system is simple, but battery deterioration occurs and power sharing becomes inefficient
Solution Approach 1:
The patent applies segmentation by dividing electric vehicles into multiple groups based on their characteristics (battery type, capacity, performance). This classification allows differentiated management strategies for each group, preventing uniform treatment that causes battery deterioration while maintaining efficient overall management through structured categorization.
2Ease of operation
If uniform charging and discharging control is applied to all electric vehicles, then control implementation is simple, but power demand sharing becomes inefficient
Solution Approach 1:
The patent implements local quality by applying different charging and discharging control strategies to different vehicle groups based on their specific characteristics. Each group receives tailored management appropriate to its battery type, capacity, and performance level, optimizing power demand sharing efficiency while maintaining reasonable operational complexity through systematic classification.
3Productivity
If classification based on multiple vehicle characteristics is implemented, then power management efficiency improves, but system complexity increases
Solution Approach 1:
The patent manages classification system complexity through segmentation by organizing vehicles into hierarchical groups based on multiple characteristics. This structured approach enables efficient power management through differentiated strategies while keeping the classification system manageable through systematic categorization rather than unstructured individual vehicle analysis.
