6 FAQs about [Battery dynamic detection]
Can a deep learning algorithm detect Li-ion battery faults?
Accurate evaluation of Li-ion battery safety conditions can reduce unexpected cell failures. Here, authors present a large-scale electric vehicle charging dataset for benchmarking existing algorithms, and develop a deep learning algorithm for detecting Li-ion battery faults.
Can deep learning be used for EV battery fault detection?
In short, existing studies do not reveal the power of deep learning for EV battery fault detection with large-scale publicly available EV charging datasets, nor do they discover how practical factors should inform algorithm design and deployment. In this work, we release three EV charging datasets with over 690,000 charging snippets from 347 EVs.
How to design an EV battery fault detection algorithm?
Designing an EV battery fault detection algorithm that is implementable and effective for both EV manufacturers and owners needs to take practical social factors into account 30, 31, such as the data availability, economic trade-offs, sensor noise, and model privacy.
Can EV battery failure detection be performed at piece level?
The TSA (Time Series Anomaly detection system) contains time-series data from Flink8 [ZWD+20]. All the anomaly labels in these time series datasets are labeled at piece level. However, as we mentioned above, piece-level labels cannot be obtained in EV battery failure detection. We can only observe vehicle breakdowns due to battery failure.
Why are anomaly detection methods not validated in realistic battery settings?
Despite the recent progress in artificial intelligence, anomaly detection methods are not customized for or validated in realistic battery settings due to the complex failure mechanisms and the lack of real-world testing frameworks with large-scale datasets.
