Electric Vehicle Power Demand Calculation via Intermediary Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Estimating a highly reliable power demand for electric vehicles is challenging due to limited information from charging stations, especially when the number of stations is small, and when charging station providers do not disclose charging results, making it difficult for business operators to accurately estimate power demand.
Innovation Solution
A power demand amount calculation system that establishes communication with vehicle-mounted devices to collect and analyze data on battery capacity, charge level, and position, allowing for the calculation of actual power demand and visualization of charging patterns, enabling accurate estimation of power needs for electric vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging stations are installed to enable electric vehicles to travel greater distances, then the reliability of power demand estimation improves, but the cost and complexity of infrastructure increases
Solution Approach 1:
The patent introduces a communication system that acts as an intermediary between charging stations and central management. This system collects charging result information automatically and transmits it to the power demand estimation system, eliminating the need for direct complex connections between numerous charging stations and the estimation system, thereby improving reliability without proportionally increasing infrastructure complexity
Solution Approach 2:
The patent implements a feedback mechanism where charging result information is continuously collected from charging stations and fed back to the power demand estimation system. This feedback loop enables accurate estimation of power demand by analyzing actual charging patterns and results, improving estimation reliability without requiring excessive charging infrastructure
2Reliability
If charging result information is collected from multiple charging station providers to improve estimation accuracy, then the reliability of power demand estimation improves, but the difficulty of information collection and coordination increases
Solution Approach 1:
The patent designs a universal communication interface and standardized information format that can be used across different charging station providers. This multi-functional communication system enables the collection of charging result information from multiple providers without requiring separate collection mechanisms for each, thereby improving estimation reliability while keeping information collection complexity manageable
Solution Approach 2:
The patent introduces a central communication management system that acts as an intermediary between multiple charging station providers and the power demand estimation system. This mediator standardizes and consolidates information from various providers, improving estimation reliability while simplifying the coordination complexity through centralized management
3Quantity of substance
If the number of charging stations is kept small to reduce infrastructure cost, then the cost decreases, but the reliability of power demand estimation deteriorates due to limited information
Solution Approach 1:
The patent implements continuous monitoring and collection of charging result information from existing charging stations. By continuously gathering data over time rather than relying on a large number of stations, the system maintains reliable power demand estimation with a smaller charging station infrastructure, reducing costs while preserving estimation quality
