Traction battery modeling

RC cell parameters for the first order model

Identification of resistance R_p (RC cell) depending on temperature and SoC

Identification of capacity C (RC cell) depending on temperature and SoC

Outputs of the first order model

• All parameters are dependent on  SOC and T, including $U_{bat} = U_{OCV} =  f(T, SOC)$.
