An information processing method that obtains charge data, travel history, and waypoint information to identify and separate power usage for different travel purposes, enabling precise calculation and billing for each purpose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charging system calculates fees based on total power transmitted to the electric vehicle, then the billing process is simple, but fees cannot be appropriately calculated according to multiple travel purposes
Solution Approach 1:
The patent segments the total power consumption into different portions corresponding to different travel purposes (work-related vs. personal use). By dividing the charging period into multiple travel segments and calculating power usage for each segment separately, the system achieves both accurate fee calculation by purpose and maintains operational simplicity through automated processing.
2Measurement precision
If the system tracks detailed travel history and waypoint information to distinguish travel purposes, then fee calculation accuracy improves, but system complexity increases
Solution Approach 1:
The patent utilizes existing multi-functional components already present in electric vehicles, such as the navigation system's waypoint recording function and the charging management system. By making these existing components serve the additional function of travel purpose identification for billing, the system achieves accurate measurement without adding significant complexity.
Solution Approach 2:
The system automatically collects travel history, waypoint information, and charging data, then autonomously processes this information to identify travel purposes and calculate fees. The electric vehicle's existing navigation and charging systems self-generate the necessary data, eliminating the need for manual input or complex external tracking infrastructure.
3Measurement precision
If the system separates power usage by travel purpose using history information and waypoint data, then appropriate fee calculation is achieved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary segmentation of charging periods into travel segments based on pre-collected travel history and waypoint information. By organizing the data structure in advance and identifying travel purposes before final fee calculation, the system reduces computational complexity during the actual billing process, thereby minimizing processing time while maintaining accuracy.

AI summary
An information processing method includes: obtaining an amount of charge when a moving body propelled by electrical power is charged by a charging facility; obtaining history information on locations that the moving body has traveled to during travels and remaining battery levels during the travels; obtaining waypoint information that indicates a location that the moving body has passed through during a first type of travel among the travels; and identifying, by using the history information and the waypoint information, a first amount of power used during the first type of travel out of the amount of charge, or a second amount of power used during a second type of travel out of the amount of charge, and outputting the first amount of power or the second amount of power, the second type of travel being the travels excluding the first type of travel.
