Abstract

Abstract

En 中文
• Proposes Fourier neural operator (FNO) and parameter-embedded FNO (PE-FNO) models for Li-ion battery temperature prediction. • Embeds partial differential equation (PDE) parameters via the channel attention mechanism to enhance model generalization ability. • Achieves root mean square error (RMSE) less than 0.07 °C and runtime 5 times faster than classical PDE solvers.
