A Neural-Network-Embedded Equivalent Circuit Model for Lithium-ion Battery State Estimation

no code implementations24 Jul 2024 Zelin Guo, Yiyan Li, Zheng Yan, Mo-Yuen Chow

Equivalent Circuit Model(ECM)has been widelyused in battery modeling and state estimation because of itssimplicity, stability and interpretability. However, ECM maygenerate large estimation errors in extreme working conditionssuch as freezing environmenttemperature andcomplexcharging/discharging behaviors, in whichscenariostheelectrochemical characteristics of the battery become extremelycomplex and nonlinear. In this paper, we propose a hybridbattery model by embeddingneural networks as 'virtualelectronic components' into the classical ECM to enhance themodel nonlinear-fitting ability and adaptability.
