Battery Measurement Data Offloading Before Damage Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Energy storage systems, such as battery arrangements in vehicles, are vulnerable to hazardous events that can cause damage, leading to the loss of critical measurement data necessary for analysis and improvement, making it cumbersome to determine the root cause and implement suitable improvements.
Innovation Solution
A computer system and battery management system are configured to detect potential battery damage and prioritize and store a subset of critical measurement data at a location unaffected by the impending damage, either remotely or at a safe distance, ensuring robust data availability for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If measurement data is stored in the energy storage system, then data availability for analysis is improved, but the data may be lost when battery damage occurs
Solution Approach 1:
The patent extracts critical measurement data from the energy storage system's internal memory and transfers it to external storage locations (remote server or alternative onboard storage) that are not affected by battery damage. This separation ensures data survival even when the battery system is compromised.
Solution Approach 2:
The system performs preliminary data protection actions by detecting hazardous events and proactively transferring measurement data to safe storage locations before battery damage occurs. This advance action ensures data is secured before the damage event compromises internal storage.
2Loss of information
If all measurement data is stored, then complete analysis capability is improved, but storage efficiency and transmission resource usage deteriorate
Solution Approach 1:
The patent applies different quality levels of data protection based on local conditions: critical data associated with hazardous events is prioritized for transfer to external storage, while non-critical data remains in internal storage. This selective approach optimizes resource usage while ensuring analysis completeness for important events.
Solution Approach 2:
Instead of transferring all measurement data, the system performs partial action by selecting and transferring only the subset of data most relevant to hazardous event analysis. This reduces transmission resource consumption while maintaining sufficient data for effective analysis.
3Reliability
If data is transferred to remote storage, then data safety is improved, but system complexity and transmission requirements worsen
Solution Approach 1:
The patent implements a multi-functional storage architecture that can operate in multiple modes: internal storage only, onboard alternative storage, or remote cloud storage. This universal system adapts to different operational scenarios and infrastructure availabilities, managing complexity through flexible configuration rather than rigid architecture.

AI summary
Disclosed is an energy storage system comprising a collection of one or more battery modules and a battery management system associated with the collection of battery modules. The battery management system is configured to detect a battery event which indicates potential upcoming damage for the collection of battery modules. The battery management system is also configured to select - based on a type of the battery event (e.g., temperature event, electrical event, chemical event) - a sub-set of measurement data from a set of available measurement data relating to the collection of battery modules, and cause the selected sub-set of measurement data to be stored at a storing location which is unaffected by the potential upcoming battery damage for the collection of battery modules. Corresponding computer system, battery management system, method, computer program product, and non-transitory computer-readable storage medium are also disclosed, as well as various equipment comprising the energy storage system.
