This document introduces a new design method for hybrid electric vehicle battery management systems that are designed to operate in harsh environments. The method uses simulation technology to predict the performance of the battery pack under various environmental conditions and to identify the optimal design parameters. The method can also be used to optimize the design of the battery pack to meet specific performance requirements.
