OCP for heat source calculation #3088
-
|
Hi Team~ I guess it is a basic question, but how does Pybamm calculate open circult potential U and dU/dT when calculating reversiable and irreverisble heating source? Is there somewhere I can check the formula U(c_s/c_max,T)? Cannot thank you more! |

Those can be found in the parameter set that you are using. For example, in Mohtat2020 you'll find functions for: graphite_ocp_PeymanMPM(sto) NMC_ocp_PeymanMPM(sto) All parameter sets would have the OCV as a function of stoichiometry but not all parameter sets would have dU/dT unless they support the thermal options. |

Thank you veryyyy much, that really helps! I found one from Ai2020.py |

graphite_entropic_change_PeymanMPM(sto, c_s_max)
