Industrial-scale battery management is complex, involving diverse tasks like estimation, prediction, and diagnostics. Each task often demands distinct data formats, temporal scales, and sensor resolutions. Current approaches require significant data and engineering effort for task-specific methods, limiting scalability and practical deployment. This paper addresses these challenges by proposing a unified, flexible framework.

15K+ Battery management works in 5 years (4K in 2024, 12%+ annual growth). Aggregating models increases computational costs.
AspectTraditional Task-Specific MethodsFMAE (Our Solution)
Data Heterogeneity Requires fixed input format, struggles with missing data, difficult to pretrain across diverse datasets.
  • Handles diverse data formats, missing channels, and temporal variations inherently.
Engineering Effort High effort for each task/system, limited scalability.
  • Minimal data & engineering effort for new tasks (finetuning paradigm).
Inter-correlation Learning Focuses on isolated tasks, limited capture of cross-snippet/channel correlations.
  • Learns unified battery representations, captures inter-correlations across snippets/channels.
Real-World Robustness Sensitive to incomplete or noisy data, may collapse with missing information.
  • Maintains performance with missing data (e.g., system voltage), robust in practical scenarios.

The Flexible Masked Autoencoder (FMAE) extends the Masked Autoencoder (MAE) paradigm with novel designs to handle battery data heterogeneity. It focuses on learning unified representations from diverse datasets, addressing the limitations of fixed input formats and missing data channels inherent in real-world battery management.

Case Study: Adaptability to Real-World Scenarios

FMAE's ability to handle missing data channels (e.g., system voltage, temperature) is crucial for real-world EV deployment. When artificially removing system-level statistics from EV datasets, FMAE employing partial channels still outperformed LSTM utilizing all channels. This validates its robustness and practical potential.

Key Takeaway: FMAE’s missed channel modeling strategy enables reliable operation even with low-priority data channels missing from cloud storage or vehicle-mounted devices.

FMAE demonstrates superior performance across five critical battery management tasks using eleven diverse battery datasets. Its ability to achieve state-of-the-art results with significantly less inference data and its robustness to missing information underscore its practical utility and efficiency.

Your Roadmap to Advanced Battery Management

A phased approach to integrating FMAE into your enterprise, ensuring a smooth transition and maximizing impact.

Phase 1: Data Assessment & Preparation (1-2 Months)

Initial audit of existing battery data sources (EV, BESS, lab), identification of data heterogeneity challenges, and establishment of secure data pipelines for centralized ingestion. Focus on unifying formats and identifying key channels for pretraining.

Phase 2: FMAE Pretraining & Initial Finetuning (2-4 Months)

Leverage existing heterogeneous battery datasets to pretrain the FMAE model, building a foundational understanding of battery dynamics. Conduct initial finetuning on specific high-priority tasks (e.g., SOH estimation, RUL prediction) with your available labeled data.

Phase 3: Integration & Validation (2-3 Months)

Integrate the finetuned FMAE models into existing BMS or enterprise systems. Validate performance against current benchmarks in real-world scenarios, including testing robustness to missing data and evaluating data efficiency gains. Deploy in a pilot environment.

Phase 4: Scalable Deployment & Expansion (Ongoing)

Full-scale deployment across your fleet or energy storage systems. Expand FMAE's application to additional battery management tasks (e.g., anomaly detection, diagnostics) and explore its potential for other dynamical systems within your organization, continuously optimizing for performance and cost.
