Abstract
Considering the long development cycle for automotive batteries, it is advantageous to develop simulation models capable of predicting system capacity and power capability as a function of the drive cycle, calendar life and climate. This paper will provide an overview of A123’s simulation methodology using the battery development for the Chevrolet Spark EV as a case study. In the subject program, 11 years of vehicle usage was simulated and then compared to results of accelerated life testing which took approximately 1.5 years to complete. The importance of thermal modeling will be also discussed using the example of a high power application whose thermal behavior is more difficult to predict.
