Multi-Vehicle Charging Priority Control for Intended Completion Order
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging systems for multiple vehicles with diverse power storage devices lack a mechanism to align charging orders with the intentions of vehicle owners, leading to inconsistent completion times and potential suspicions of malfunctions.
Innovation Solution
A charging system with a controller that manages charging orders based on manual priority requests and approvals, allowing owners to prioritize charging for their vehicles, and adjusts charging parameters to ensure completion in intended orders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging is performed simultaneously for multiple vehicles based on connection order, then charging station utilization is improved, but charging completion order does not align with user expectations
Solution Approach 1:
The system performs preliminary actions by notifying users of the intended charging completion order before charging starts, and by pre-establishing priority rules based on connection order. This allows users to understand the charging schedule in advance and make informed decisions about whether to wait or disconnect, resolving the mismatch between charging completion order and user expectations while maintaining simultaneous charging operations
2Productivity
If charging priority is determined by vehicle SOC and charging capability, then charging efficiency is improved, but users experience inconsistency and suspicion of malfunctions
Solution Approach 1:
The system implements feedback by notifying users of the determined charging completion order before charging begins, and by providing real-time charging status information. This transparency allows users to understand why their vehicle is charged in a particular order, eliminating suspicions of malfunctions while still optimizing charging efficiency based on SOC and charging capabilities
Solution Approach 2:
The charging control device determines and communicates the charging completion order to users before charging starts. This preliminary notification allows users to plan accordingly and understand the charging schedule in advance, building trust in the system's fairness and consistency while maintaining efficient charging operations
3Stability of the object's composition
If subsequent vehicles wait for preceding vehicles to complete charging, then charging order consistency is improved, but simultaneous charging function is lost
Solution Approach 1:
The system performs preliminary determination of charging completion order based on connection order before charging starts, and communicates this order to all users. This allows multiple vehicles to charge simultaneously while maintaining a predetermined consistent completion order, combining the benefits of both simultaneous charging and order consistency

AI summary
A charging system includes a controller including a simultaneous charging determination unit for determining that a plurality of power storage devices are connected; a priority request reception unit for accepting a request for charging a predetermined power storage device preferentially to another power storage device; a request announcement unit for notifying that a request has been made; a prioritized charging approval unit for approving preferential charging of a predetermined power storage device based on the request; a prioritized charging instruction unit for preferentially charging the predetermined power storage device preferentially to charging the other power storage device when approval is given; and a basic charging order setting unit for setting the order of charging of the plurality of power storage devices in the order in which the power storage device is connected to the charging station when there is no priority request and when there is no preferential charging approval.
