Large Models for Battery Prognostics and Health Management: A Review and Future Roadmap
Source: ArXiv AI ↗ (cross-verified by 2 outlets — full list below)
Large Models (LMs) based on Transformer architectures and self‑supervised pre‑training are being positioned as a breakthrough for Battery Prognostics and Health Management (BPHM), a field essential to the safe and cost‑effective operation of batteries in electric vehicles, grid storage, and consumer electronics. Traditional BPHM methods—ranging from physics‑based models to task‑specific deep learning—struggle with computational inefficiency, heavy reliance on extensive labeled run‑to‑failure data, limited cross‑domain generalisation, and poor interpretability. The review introduces LMs as a new paradigm that can address these bottlenecks, outlining the core enabling technologies such as large‑scale multimodal datasets, parameter‑efficient fine‑tuning (PEFT), and the underlying Transformer design.
The authors organise recent advances into four key dimensions: (1) alleviating data scarcity through self‑supervised learning that leverages abundant unlabeled battery data; (2) improving generalisation and robustness across different battery chemistries and operating conditions; (3) integrating domain knowledge to enhance model interpretability, often by embedding physics‑based constraints; and (4) facilitating system‑level automation for end‑to‑end battery management. While early results demonstrate that LMs can reduce the need for exhaustive failure testing and provide more reliable health predictions, the review highlights persistent challenges, including limited access to high‑quality datasets, the difficulty of validating intelligent models for industrial deployment, concerns over trustworthiness, and the practicalities of deploying large models on edge devices.
To steer future work, the paper proposes a roadmap centred on creating collaborative data ecosystems that pool diverse battery datasets, establishing rigorous validation protocols for industrial use, embedding physics‑informed designs to boost trust, and developing efficient on‑device inference techniques. By charting these directions, the review aims to equip researchers and practitioners with a systematic framework for advancing LM‑driven BPHM, ultimately enabling next‑generation battery management systems that operate safely, reliably, and autonomously throughout the entire battery lifecycle.

The U.S.'s central bank rate currently stands at 3.75%, so a global rates move like this could feed through to local borrowing costs. The U.S.'s economy is growing at 2.3% with inflation at 3.2%, the backdrop this story's effects play out against locally. Housing-market effects like this are usually felt most where mortgage rates track the U.S.'s own central bank rate closely. With the U.S.'s unemployment at 4.4%, personal-finance effects like this land on a labour market that is currently fairly stable. Health-system effects are harder to localise from economic indicators alone — the real impact in the U.S. depends more on local healthcare capacity than the figures above.
