• Battery Management and Safety


icon

Estimation and control of the states of the battery (including temperature, state of charge, and state of health) are essential to extract the maximum usable energy and highest available power while maintaining safe operation in hybrid and electric vehicle systems. The role of the Battery Management System (BMS) is to collect the current voltage and temperature sensor measurements from the battery cells to manage the power flows and provide the functional safety, prognostic, and diagnostic information needed to ensure safe and efficient operation. This course reviews the modeling techniques, concepts, and algorithms used in advanced battery management systems.
