Abstract

The performance and life-cycle of an automotive Lithium Ion (Li-Ion) battery pack is heavily influenced by its operating temperatures. For that reason, a Battery Thermal Management System (BTMS) must be used to constrain the core temperatures of the cells between 20°C and 40°C. In this work, an accurate electro-thermal model is developed for cell temperature estimation. A cascaded thermal management control loop is then proposed to dynamically keep battery temperatures within the predefined limit. Simulation results are provided under standardized urban driving cycle conditions, demonstrating the correct operation of the proposal.
