Electro-Thermal Modeling of New Prismatic Lithium-Ion Capacitors

Abstract

Due to increasing demand of using high energy and high power storages applicable in different applications such as hybrid electric vehicles, hybrid Lithium Ion Capacitors have been taken into account more than ever. In this paper a second order model is considered for and based on that model and HPPC (hybrid pulse power characterization) test, parameters have been identified. Then based on evaluation of internal resistance total power losses have been calculated. Regarding to the cell temperature prediction, a first order model has been considered and based on measured surface temperature and also calculated power losses, parameters of thermal model have been identified. At the end both electrical and thermal models have been merged and final model has been validated.
