Solution Overview
Problem
Existing systems fail to consider the progression of battery deterioration in multiple vehicles when managing electric power delivery and vehicle operations.
Innovation Solution
A system that categorizes vehicles into groups based on battery deterioration levels and states of charge, prioritizing the use of vehicles with lower deterioration and higher charge for electric power delivery and operation tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are selected for electric power delivery without considering battery deterioration levels, then electric power supply/demand can be met, but battery deterioration progresses unevenly across the vehicle fleet
Solution Approach 1:
The patent segments the vehicle fleet into multiple groups based on battery deterioration levels (e.g., first group with lower deterioration, second group with higher deterioration). This segmentation enables differentiated management strategies for different battery conditions, allowing the system to meet electric power demands while distributing wear across the fleet to maintain overall reliability.
Solution Approach 2:
The patent changes the selection parameter from arbitrary or random vehicle selection to selection based on battery deterioration levels. By using deterioration level as the key parameter for grouping and selection, the system optimizes both productivity (electric power delivery) and reliability (battery health management) simultaneously.
2Device complexity
If batteries are used for electric power delivery without categorization, then system complexity is reduced, but battery deterioration cannot be properly managed
Solution Approach 1:
The patent introduces segmentation by categorizing vehicles into groups based on battery deterioration levels. While this adds some management structure, it enables automated selection algorithms that actually reduce operational complexity by eliminating the need for manual assessment of each vehicle's battery condition.
Solution Approach 2:
The patent changes the management approach from treating all vehicles uniformly to using deterioration level as a key parameter for categorization. This parameter-based management simplifies decision-making by providing clear criteria for vehicle selection in different operational scenarios.
3Power
If vehicles with higher state of charge are used for power delivery, then immediate power supply capability is improved, but battery deterioration may accelerate
Solution Approach 1:
The patent segments vehicles into groups considering both deterioration levels and state of charge. This enables the system to select appropriate vehicles based on current needs: vehicles with higher charge can be used when power delivery is needed, while vehicles with lower charge or higher deterioration are protected, balancing immediate power requirements with long-term battery health.
Solution Approach 2:
The patent performs preliminary categorization of vehicles based on battery characteristics before power delivery operations. This advance organization allows the system to quickly identify suitable vehicles for power delivery while considering their remaining capacity and deterioration level, preventing overuse of vulnerable batteries.
