FlowBatt
A conditional generative framework based on flow matching with a diffusion Transformer backbone, used for probabilistic prediction of battery State of Health (SOH) trajectories across chemical systems. It can generate multiple degradation trajectories and provide empirical prediction intervals.
Timeline (last 90 days)
FlowBatt is a battery degradation prediction framework based on conditional generative models, using a flow matching method combined with a Diffusion Transformer (DiT) backbone to generate future SOH trajectories conditioned on early-cycle capacity data.
FlowBatt achieves the best trajectory-level SOH prediction performance on five public benchmark settings, with error below 2.5%.
FlowBatt remains competitive on RUL prediction, compared with supervised learning models, diffusion-based trajectory models and established RUL prediction baselines under shared data splits.
FlowBatt can generate multiple plausible trajectories, providing empirical prediction intervals for degradation modeling, an output dimension that deterministic methods cannot offer.
The FlowBatt research team introduces explainable AI analysis to diagnose and improve the conditional encoder, using XAI as a diagnostic tool during model development rather than for post-hoc explanation.
The paper does not disclose the model's performance at different data scales, nor does it discuss the applicability of inference cost to embedded battery management systems.
FlowBatt's cross-chemistry generalization capability is validated on five benchmarks, but data distribution drift in real deployment remains an open problem.
