Battery management, which controls battery temperature and SOC, is important for safe and efficient long-term use with low degradation of lithium-ion battery in the electric vehicle. To design a suitable battery management system, it is effective to use a vehicle system 1D simulation model. We studied an appropriate battery degradation model for the vehicle system 1D simulation model based on lithium iron phosphate battery test data. Implemented physical model of anode SEI layer growth and electrode structural disorder to predict calendar and cycle degradation respectively. After implementing the degradation models, we analyzed the long-term degradation behavior by assuming a real-world use case of electric vehicle driver. Evaluated the contribution of calendar and cycle degradation to the real-world degradation. [ABSTRACT FROM AUTHOR] |
