BEV laboratory, with focus on battery performance

Introduction

• Introduction to energy storage systems for automotive applications
• Notation and definitions
• Overview of li-ion battery technology: operating principles, properties of electrode materials, state of the art, materials for next-generation cells
• Battery cell modeling

Battery systems

• System integration principles for modules and packs
• Battery Management Systems and state of charge and power estimation
• Thermal Management Systems (TMS), solutions for passive and active cooling
• Battery charging standards, service equipment. Principle of charge control and balancing
• Definition of State of Health (SOH) and Residual Useful Life (RUL)
• Test protocols to characterize degradation in cells

• The course closes with a laboratory in which the participants will explore the simulated performance of a BEV using a simulator that is capable of simulating many important aspects of a battery electric vehicle including battery electrical and thermal management, power limits, SOC estimation and other important functions.
