Battery Log Data Acquisition and Automated Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, such as fires at energy storage systems, existing battery management systems require manual data backup, leading to time and cost inefficiencies, and data loss when the system is damaged, making it difficult to analyze the cause of accidents.
Innovation Solution
A communication apparatus with a data collecting unit, diagnosing unit, and communicating unit that obtains, diagnoses, and transmits log information from battery management systems to a management server, enabling automated data storage and notification, thus facilitating rapid data retrieval and accident analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual data backup is performed by visiting the site, then data can be obtained, but it consumes much time and cost and data may be lost in emergency situations
Solution Approach 1:
The system performs preliminary actions by automatically collecting and storing battery management data in real-time before emergencies occur. The black box device continuously records operational parameters and stores them locally, ensuring data is preserved and ready for retrieval without requiring manual intervention during critical moments.
Solution Approach 2:
The system implements self-service through automated data collection and transmission capabilities. The black box device autonomously monitors battery parameters, stores data locally, and automatically transmits information to remote servers without requiring human operators to visit the site, thereby eliminating time consumption and preventing data loss.
2Extent of automation
If data transmission is performed in specific time units, then the system operates automatically, but data at the exact moment of accident may not be entirely obtained
Solution Approach 1:
The system ensures continuity of useful action by continuously collecting and recording battery operational data without interruption. The black box device maintains constant monitoring of voltage, current, temperature, and other parameters, ensuring that data is captured at every moment including the precise instant when an accident occurs, thereby maintaining both automation and measurement precision.
3Reliability
If manager visits the site to manually backup data, then data can be secured, but it is difficult to respond rapidly in emergency situations
Solution Approach 1:
The system introduces an intermediary element - the black box device with automatic data transmission capability - that acts as a mediator between the battery system and remote servers. This intermediary automatically captures, stores, and transmits data without requiring human intervention, ensuring both data security through reliable storage and rapid response speed through automated transmission to customer service centers.

AI summary
A communication apparatus includes a data collecting unit for obtaining log information about a state of a battery from a battery management system that manages the battery, a first storing unit including reference log information for determining abnormality of the battery, and a diagnosing unit for diagnosing abnormality of the battery by comparing the log information about the state of the battery with the reference log information.
