Vehicle Battery Charging Plan Adjustment for Storage Deviations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging and discharging operations not scheduled in a charging/discharging plan for a power storage device on a vehicle can lead to deviations from the planned amount of power storage, causing inconvenience and potential power imbalances.
Innovation Solution
A management system that includes a management apparatus to manage the power storage device, allowing for adjustments to the charging plan based on deviations from a predetermined allowable range, enabling scheduled charging and discharging while minimizing such deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If charging and discharging operations are allowed outside the scheduled charging/discharging plan, then user convenience is improved, but deviation from the planned power storage amount increases
Solution Approach 1:
The management apparatus continuously monitors the actual power storage amount and compares it with the planned power storage amount. When deviation exceeds a threshold, the system automatically generates corrective charging/discharging instructions to bring the actual value back into the allowable range, creating a closed-loop feedback control system.
Solution Approach 2:
The charging/discharging plan is made dynamically adjustable rather than fixed. The management apparatus can modify the plan in real-time based on actual power storage deviations, user requests, and system constraints, allowing the system to adapt to changing conditions while maintaining overall plan integrity.
2Manufacturing precision
If charging and discharging operations are prohibited outside the scheduled plan, then power storage amount control precision is improved, but user convenience deteriorates
Solution Approach 1:
The system introduces an allowable deviation range as a flexible parameter rather than enforcing a strict zero-deviation constraint. This parameter-based approach allows controlled flexibility in power storage amount while maintaining overall plan adherence, balancing precision requirements with operational flexibility.
3Manufacturing precision
If the charging plan is modified in response to power storage deviations, then power storage amount control precision is improved, but device complexity increases
Solution Approach 1:
The management apparatus automatically detects power storage deviations and generates corrective charging/discharging instructions without requiring manual intervention. The system serves itself by autonomously monitoring, analyzing, and correcting plan deviations, reducing the need for complex external control mechanisms.

AI summary
A management system includes a management apparatus that manages a power storage device mounted on a vehicle. The management apparatus is configured to instruct the vehicle to charge the power storage device in accordance with a charging plan that indicates a charging schedule in a plan period. The management apparatus is configured to obtain a power storage plan for the power storage device with respect to the plan period. The power storage plan includes at least one piece of plan data that indicates combination of time within the plan period and a planned value of an amount of power storage in the power storage device at that time. The management apparatus is configured to modify the charging plan in response to determination that the amount of power storage in the power storage device deviates from the power storage plan beyond an allowable range.
