EV Charging Cost Confirmation for Reliable Payment Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for charging electric vehicles often result in settlement errors when paying for charging costs, leading to unreliable execution of payment.
Innovation Solution
An information processing method and device that calculates and displays the charging amount and cost based on user-specific electricity consumption data, allowing users to approve and execute payment requests before charging is completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If payment is executed after charging is completed, then the charging service can be provided, but settlement errors occur and payment reliability deteriorates
Solution Approach 1:
The system displays the charging cost to the user before the charging service is completed, allowing the user to confirm and approve the payment in advance. This preliminary action of showing the cost and obtaining user confirmation before finalizing payment prevents settlement errors and ensures payment reliability, while still maintaining the charging service flow.
2Reliability
If charging cost is calculated and displayed before charging completion, then payment reliability improves, but the charging process complexity increases
Solution Approach 1:
The charging process is segmented into distinct stages: charging execution, cost calculation, cost display, user confirmation, and payment execution. By separating the cost display and confirmation steps from the charging execution, the system maintains simplicity in each individual step while ensuring overall payment reliability through the structured sequence.
