Adaptive EV Charging Control for Irregular Scheduled Usage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging control methods for electric moving bodies do not account for irregular scheduled usage, leading to reduced convenience and inefficiency.
Innovation Solution
A charging control method that acquires scheduled usage and necessary remaining capacity, and adjusts the charging plan to ensure the necessary capacity is reached by the scheduled usage start time, even for irregular usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a fixed charging plan is set in advance, then charging automation is improved, but adaptability to irregular scheduled usage deteriorates
Solution Approach 1:
The charging control apparatus dynamically adjusts the charging plan based on acquired scheduled usage information. The system transitions from a static pre-set charging plan to a dynamic adaptive plan that responds to irregular usage patterns, maintaining automation while improving versatility.
Solution Approach 2:
The system acquires scheduled usage information and uses this feedback to modify the charging plan. By continuously monitoring usage patterns and adjusting charging accordingly, the system maintains high automation while adapting to irregular usage scenarios.
2Use of energy by moving object
If the battery is charged to full capacity in advance, then energy availability is improved, but battery deterioration accelerates
Solution Approach 1:
The system charges the battery to only the necessary remaining capacity required for the scheduled usage, rather than charging to full capacity. This partial charging approach ensures sufficient energy availability while reducing the time the battery spends at high charge levels, thereby slowing deterioration.
Solution Approach 2:
The system dynamically changes the charging target parameter from fixed full capacity to variable necessary remaining capacity based on scheduled usage requirements. This parameter adjustment optimizes both energy availability and battery longevity.
3Adaptability or versatility
If charging is performed multiple times to meet irregular usage, then energy availability is improved, but charging complexity increases
Solution Approach 1:
The system segments the charging process into multiple charging sessions when irregular usage requires it. By dividing the total charging need into discrete charging events, the system handles complex irregular usage patterns while maintaining manageable charging operations.
Solution Approach 2:
The system performs preliminary charging actions in advance of scheduled usage based on predicted requirements. By proactively charging before usage events, the system simplifies the overall charging management while ensuring energy availability for irregular usage patterns.

AI summary
Scheduled usage of an electric moving body that moves using a battery as a power source is acquired; a necessary remaining capacity that is a charging state necessary for the scheduled usage is acquired; and if the necessary remaining capacity is not reached by a start timing of the scheduled usage, a charging plan set in advance prior to the acquired scheduled usage is changed in a manner that the necessary remaining capacity is reached by the start timing of the scheduled usage.
