Power Storage Management System for Shared Battery Lifespan Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power storage management systems in smart grids struggle to manage and prevent deterioration of shared power storage apparatuses due to improper usage by multiple consumers, as they cannot accurately identify users or apparatuses that accelerate deterioration.
Innovation Solution
A power storage management system that includes a receiver, sender identifier, memory, and deterioration degree estimator to track and restrict usage from users or apparatuses that cause excessive wear, using sensors to monitor changes in full charge capacity, internal resistance, and temperature, and correlating this data to identify and restrict deterioration-accelerating behavior.

Engineering Contradiction Analysis
1Productivity
If multiple users share a power storage apparatus in a smart grid network, then resource utilization and productivity are improved, but the power storage apparatus is subjected to accelerated deterioration due to improper usage patterns
Solution Approach 1:
The system implements a feedback mechanism by monitoring power storage status information (charge/discharge cycles, capacity, temperature) and analyzing usage patterns of each user. The management apparatus provides feedback to users about their usage impact on the shared power storage apparatus, enabling them to adjust their usage behavior to reduce deterioration while maintaining resource utilization.
Solution Approach 2:
The system changes operational parameters dynamically based on usage patterns. It adjusts charge/discharge rate limits, capacity thresholds, and operational constraints for different users based on their historical usage behavior and the current state of the power storage apparatus. This allows optimal resource utilization while preventing deterioration through parameter-based control.
2Reliability
If the system monitors and identifies each user's usage patterns to prevent deterioration, then the power storage apparatus lifespan is protected, but the device complexity and measurement requirements increase
Solution Approach 1:
The management apparatus performs multiple functions using a unified system: it monitors power storage status, identifies user usage patterns, calculates deterioration contributions, and provides control signals. This multi-functional approach reduces overall system complexity compared to having separate specialized systems for each function.
Solution Approach 2:
The system enables the power storage apparatus to self-monitor its own status and self-assess deterioration causes by analyzing usage patterns. The apparatus automatically generates management information and identifies problematic users without requiring external intervention, reducing the complexity of external monitoring infrastructure.
3Reliability
If the system implements real-time monitoring and control of user usage, then the power storage apparatus is protected from deterioration, but the loss of time for data collection and analysis increases
Solution Approach 1:
The system performs preliminary analysis by continuously collecting and pre-processing usage data in the background during normal operation. When deterioration risks are detected or assessment is needed, the analysis results are already prepared or can be quickly generated, minimizing the time loss for critical assessments.
Solution Approach 2:
The monitoring and data collection operate continuously in the background without interrupting the normal charge/discharge operations. The system maintains continuous surveillance of power storage status and usage patterns, enabling real-time protection without significant time loss or operational interruptions.

AI summary
A power storage management system, a power storage apparatus, a power storage management method are provided. The power storage management system includes a receiver part, a sender identifying part, a memory part and a deterioration degree estimating part. The sender identifying part identifies an external apparatus that transmitted a control signal received by the receiver part. The memory part stores apparatus information related to the external apparatus identified by the sender identifying part and power storage status information related to the status change of the power storage apparatus caused by charging or discharging performed according to the control signal transmitted from the external apparatus. The deterioration degree estimating part estimates the deterioration degree of the power storage apparatus to which a charge/discharge control is performed according to the control signal transmitted from the sender apparatus based on the apparatus information and the power storage status information.
