In this paper, we demonstrate the AutoLion™ suite: a collection of battery simulation tools for electric drive vehicle (EDV) Li-ion cell and pack development. At the heart of each simulation tool is a thermally coupled battery (TCB) model that simultaneously computes electrochemical and thermal effects of large format cell and pack operation. As we will demonstrate through illustrative examples, TCB modeling is critically important for properly simulating EDV Li-ion cells and packs under conditions of interest to the automotive industry (cold-start, rapid charge, safety simulations, etc.). Furthermore, we highlight a one-of-a-kind degradation model that simultaneously predicts cell performance and degradation over the life cycle of the battery.
