Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insufficient electric vehicle charging infrastructure and regional characteristics lead to difficulties in finding available charging stations due to charger failures or long waiting times, as existing systems lack personalized recommendations based on user and vehicle information.
Innovation Solution
A charging station information providing server and method that uses a charging station evaluation model and recommendation model to generate customized recommendations for users by integrating user and vehicle information with road condition data, ensuring optimized charging station suggestions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a charging station recommendation system is provided without personalized customization, then the system complexity is reduced, but the recommendation accuracy and user satisfaction deteriorate
Solution Approach 1:
The system changes parameters by integrating multiple data dimensions including user information (preferences, historical behavior), vehicle information (battery capacity, charging speed requirements), charging station information (availability, pricing, facilities), and road condition information (traffic, weather). These parameter changes enable personalized recommendations while maintaining manageable system complexity through structured data processing.
Solution Approach 2:
The recommendation system is segmented into distinct functional modules: a charging station evaluation model that assesses station quality, a recommendation model that generates personalized suggestions, and multiple data acquisition modules that collect specific information types. This segmentation allows the complex system to be managed through independent, specialized components.
2Reliability
If real-time road condition information is integrated into the recommendation system, then the reliability of charging station availability is improved, but the data processing complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-collecting and storing road condition information, charging station status data, and user preference profiles before generating recommendations. This advance preparation reduces the complexity of real-time processing by having data ready in structured formats, enabling faster and more reliable availability assessments.
Solution Approach 2:
The system introduces intermediary components including data acquisition modules that specialize in collecting specific information types, data processing units that transform raw data into meaningful insights, and the recommendation model that acts as an intermediary between multiple data sources and the final recommendation output. This intermediary structure manages data processing complexity while improving reliability.
3Ease of operation
If customized recommended charging station information is provided based on multiple data sources, then the user experience is improved, but the information processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing user preference data, vehicle specifications, and charging station characteristics in structured formats. This advance preparation enables faster information processing during actual recommendation generation, reducing the time penalty associated with providing customized recommendations while maintaining enhanced user experience.
Solution Approach 2:
The recommendation system dynamically adjusts its processing based on available data and user needs. The system can adaptively select which data sources to prioritize and how deeply to process information based on the specific recommendation context, balancing processing time with recommendation quality to maintain good user experience without excessive processing delays.
Data Source
AI summary
A charging station information providing server receives a charging station recommendation request from an external device, generates, in response to the received charging station recommendation request, a charging station recommendation query based on user information and vehicle information corresponding to a user of the external device, obtains customized recommended charging station information based on charging station list information obtained by using a charging station evaluation model, and road condition information, by using a charging station recommendation model that takes the generated charging station recommendation query as input, and transmits the obtained customized recommended charging station information to the external device.
