EV Charging Contribution Scoring for Aggregator Reward Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for utilizing electric vehicles as distributed power sources do not provide benefits to users when vehicles are charged or discharged at locations other than specific parking lots, such as home or workplace, limiting their contribution to power supply and demand adjustment.
Innovation Solution
An information processing method that acquires the connection status of electric vehicles to chargers managed by an aggregator, specifies the degree of contribution based on this status, and provides benefits, such as points, to users for their participation in power supply and demand adjustment, which can be used for charging fees at public chargers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reward points are only given for charging at specific parking lots, then the system can manage charging locations centrally, but users receive no benefit for charging at home or workplace, reducing overall participation
Solution Approach 1:
The system applies universality by enabling the reward mechanism to function across multiple charging locations (public parking lots, home chargers, workplace chargers) rather than being limited to a single centralized location. This allows the same incentive structure to work universally across different charging scenarios, increasing both location flexibility and user participation
2Measurement precision
If the system tracks connection status at all locations, then it can accurately measure contribution to power supply and demand adjustment, but the system complexity increases
Solution Approach 1:
The system introduces an intermediary component (the benefit management server or aggregator) that acts as a mediator between diverse charging locations and the central control system. This intermediary standardizes data collection from different locations, enabling accurate contribution measurement without requiring complex direct integration with every charging point
Solution Approach 2:
The system changes the measurement parameter from tracking detailed operational data at each location to monitoring connection status (connected/not connected) and duration. This parameter simplification maintains sufficient accuracy for measuring power supply and demand adjustment contribution while significantly reducing system complexity

AI summary
An information processing method that is executed by a computer includes a process of: acquiring information indicating a connection status of an electric vehicle to a charger/discharger managed by an aggregator; specifying a degree of contribution to the aggregator by the electric vehicle according to the connection status; and giving a benefit in association with a user of the electric vehicle according to the specified degree of contribution. Preferably, the degree of contribution is specified on the basis of a parallel waiting time of the electric vehicle for the charger/discharger, the number of parallel waiting operations, the number of times the electric vehicle is charged and discharged through the charger/discharger, a charge and discharge time, charge and discharge power, or an amount of charge and discharge power.
