Server Coupon Issuance for CO2-Free EV Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems do not effectively promote the use of renewable energy for external vehicle charging and visiting shops near charging stations, lacking a method to incentivize users to utilize CO2-free charging and visit shops during less crowded times.
Innovation Solution
A charging processing system that includes a power supply facility generating CO2-free energy, electric vehicles, mobile terminals, and a server that issues coupons to users for CO2-free charging, with the server using user attribute information to notify users of coupon availability and optimize visit times based on customer traffic rates and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coupons are issued to all users for CO2-free charging, then user participation in renewable energy charging increases, but marketing costs and system complexity increase
Solution Approach 1:
The patent applies local quality by segmenting users based on their attributes (e.g., environmental consciousness, charging behavior patterns) and providing differentiated coupon strategies to different user groups. The server stores user attribute information and selectively issues coupons to users with specific attributes, rather than uniformly to all users, thus reducing overall system complexity while maintaining high participation rates among target groups.
Solution Approach 2:
The system performs preliminary action by pre-analyzing user attributes and pre-determining which users should receive coupons before the actual charging event. The server proactively identifies users with specific attributes and notifies them of upcoming coupon availability, allowing users to plan their charging visits in advance during less crowded periods, thereby optimizing resource allocation and reducing real-time processing complexity.
2Loss of time
If coupons are issued during peak charging hours, then users can charge immediately, but shop crowding increases and user experience deteriorates
Solution Approach 1:
The system applies preliminary action by notifying users of coupon availability in advance before their intended charging visit. Users receive notification of upcoming coupons and can plan to visit the charging station during less crowded periods, thereby avoiding peak-hour congestion at both the charging station and the shop, improving overall user experience while maintaining convenient access to charging services.
Solution Approach 2:
The patent implements dynamics by making coupon issuance timing flexible and adaptive to user attributes and charging station conditions. Rather than issuing coupons at fixed intervals or uniformly, the system dynamically adjusts coupon notification timing based on individual user profiles, allowing users to receive notifications at optimal moments that align with their preferences and the current charging station status, thereby balancing immediate charging needs with reduced crowding.
3Loss of information
If user attribute information is collected and analyzed, then targeted coupon notification improves, but data privacy concerns and processing requirements increase
Solution Approach 1:
The system applies local quality by collecting and processing only the specific user attributes necessary for effective coupon targeting, rather than gathering comprehensive user data. The server stores and analyzes focused attributes such as charging behavior patterns, environmental consciousness indicators, and preferred charging times, enabling precise user segmentation and targeted notification while minimizing data processing requirements and privacy concerns through selective data collection.

AI summary
A charging processing system includes: a power supply facility that supplies CO2 free power; electrically powered vehicles that each perform CO2 free charging to charge an onboard power storage device using the CO2 free power supplied from the power supply facility; mobile terminals portable by users who own the electrically powered vehicles; and a server. The server issues a coupon to a user of an electrically powered vehicle in which the CO2 free charging is performed, the coupon being usable at a shop located around the power supply facility. The server includes: a storage device that stores user attribute information in which a user ID and an attribute of each user are associated with each other; and a control device that extracts a user who has a specific attribute by making reference to the user attribute information and that notifies coupon advance-notice information to the extracted user.
