Dynamic Notification Timing for EV Charging Turnover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging system for electric vehicles often results in a low user turnover rate at power supply facilities, as users tend to occupy these facilities for extended periods, leading to insufficient availability for other users and decreased utilization rates.
Innovation Solution
A charging system that includes a vehicle, a power supply facility, and a mobile terminal, where users can set personalized notification conditions and receive timely notifications to encourage the timely completion of charging sessions, along with server-determined conditions to urge users to stop using the facilities, thereby increasing turnover rates and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the notification condition is set to notify users after a certain period since charging start, then users are controlled to stay in the installation for a long time, but the user turnover rate of power supply facilities decreases
Solution Approach 1:
The notification timing is made dynamic by allowing users to freely set their preferred notification timing rather than using a fixed predetermined period. The system adapts to individual user needs while still providing timely notifications to encourage facility turnover.
Solution Approach 2:
The notification condition parameter is changed from a fixed time-based condition to a user-configurable condition that can be set according to individual preferences, thereby balancing user convenience with facility utilization efficiency.
2Productivity
If the notification is provided to users at an early stage to urge them to stop using the facility, then the user turnover rate increases, but user convenience is impeded
Solution Approach 1:
The notification timing is dynamically adjusted based on user preferences rather than being fixed at an early stage. Users can set their ideal notification timing, making the system both productive and convenient.
Solution Approach 2:
Users themselves determine the appropriate notification timing by configuring their preferences, eliminating the need for the system to impose a one-size-fits-all early notification schedule.
3Productivity
If notifications are provided frequently to users, then the user turnover rate increases, but user convenience is impeded
Solution Approach 1:
The notification frequency parameter is changed from frequent fixed-interval notifications to a single user-configurable notification timing, reducing notification fatigue while maintaining turnover effectiveness.
Solution Approach 2:
The system transitions from a static frequent notification schedule to a dynamic user-preferred timing approach, optimizing both turnover rate and user experience.

AI summary
A charging system includes a vehicle, a power supply facility, a mobile terminal, and a server. The power supply facility performs external charging by supplying power to the vehicle. The mobile terminal receives a user input from a user of the vehicle and provides a notification to the user. The server communicates with the mobile terminal. The mobile terminal sets a first notification condition in the server in response to the user input. A second notification condition is set in the server in advance. The server determines whether or not each of the first notification condition and the second notification condition is satisfied during the external charging. When the first notification condition is satisfied, the server provides a first notification to the user through the mobile terminal. When the second notification condition is satisfied, the server provides a second notification to the user through the mobile terminal.
