Solution Overview
Problem
Existing energy storage systems face challenges in efficiently managing and reporting faults within battery management systems, particularly in large-scale power storage systems where direct access is dangerous and inefficient, leading to risks and inefficiencies in monitoring and maintenance.
Innovation Solution
An apparatus is provided that receives state information from the battery management system, compares it with prestored reference values to generate fault information, and displays this information externally, using LEDs to indicate error conditions, allowing for remote monitoring and minimizing risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If direct access to battery management system is implemented for monitoring, then monitoring capability is improved, but safety risk increases due to dangerous storage space
Solution Approach 1:
The display device is extracted from the dangerous storage space and positioned outside of it. The receiving device collects fault information from the battery management system within the storage space, transmits it externally, and displays it on a device located outside the dangerous area, thereby enabling monitoring without direct access to the hazardous environment.
Solution Approach 2:
The receiving device and transmission system act as intermediaries between the battery management system inside the storage space and the display device outside. This intermediary mechanism allows fault information to be conveyed without requiring human operators to enter the dangerous storage space, thus eliminating direct exposure to safety risks.
2Object-affected harmful factors
If remote monitoring is implemented, then safety is improved, but monitoring efficiency deteriorates due to indirect access
Solution Approach 1:
The mechanical approach of direct visual inspection and physical access to the battery management system is replaced with an electronic information transmission system. The receiving device electronically captures fault information, transmits it via communication signals, and the display device presents it externally, achieving both safety and efficiency through automated electronic monitoring.
Solution Approach 2:
The fault information from the battery management system is copied and transmitted to an external display device. Instead of requiring direct access to the original system, a copy of the critical fault information is made available outside the storage space, enabling safe and efficient monitoring of the same data remotely.
3Reliability
If comprehensive fault monitoring is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The display device is designed with multi-functionality to handle various types of fault information from the battery management system. It can display different fault codes, severity levels, and status information through a unified interface, reducing the need for multiple specialized monitoring devices and thereby managing complexity while maintaining comprehensive reliability.
