Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public charging stations often have inaccurate or outdated property information, leading to difficulties for electric vehicle users in locating and efficiently charging at these stations, due to incorrect geolocation, delayed charging responses, and suppression of simultaneous activations.
Innovation Solution
A method where electric vehicles connected to a charging station report charging parameters to an external evaluation entity, which evaluates these parameters to adapt and correct property information, such as geolocation and charging behavior, for future charging processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging parameters are collected and evaluated from multiple electric vehicles, then the accuracy and reliability of property information is improved, but the complexity of the system increases
Solution Approach 1:
An external evaluation entity is introduced as an intermediary between electric vehicles and charging stations. This entity collects charging parameters from multiple vehicles, evaluates them statistically, and determines accurate property information. The intermediary handles the complexity of data collection and analysis, while individual vehicles and charging stations interact with a simplified interface.
Solution Approach 2:
The system implements feedback by collecting actual charging parameters from electric vehicles that have used the charging station, evaluating these parameters statistically, and using the results to determine and update property information. This feedback loop continuously improves the accuracy of charging station information based on real-world usage data.
2Measurement precision
If charging parameter data is collected and evaluated statistically, then the precision of property information is improved, but the time required for data processing increases
Solution Approach 1:
The external evaluation entity continuously collects and pre-processes charging parameters from multiple electric vehicles in the background. By the time property information is needed, the statistical evaluation has already been performed or is in progress, reducing the time required at the moment of information retrieval.
Solution Approach 2:
The system performs self-service by automatically collecting, evaluating, and updating property information without requiring manual intervention. The external evaluation entity autonomously processes charging parameters from multiple vehicles and determines accurate property information, eliminating the need for manual data entry or verification.
3Loss of information
If multiple electric vehicles report charging parameters to an external entity, then the completeness of information is improved, but the communication overhead increases
Solution Approach 1:
Multiple charging parameter reports from different electric vehicles are merged and consolidated by the external evaluation entity. Instead of each vehicle communicating directly with individual charging stations, all data flows to a central evaluation entity that combines the information, performs statistical analysis, and produces comprehensive property information.
Solution Approach 2:
The external evaluation entity serves multiple functions: collecting data from various electric vehicles, evaluating charging parameters statistically, determining property information for charging stations, and providing this information back to the system. This multi-functional entity handles diverse data types and communication protocols in a unified manner.
