About

Dr. Sang Choi is a leading researcher in advanced manufacturing and automation, with a primary focus on robotic ultrasonic welding for electric vehicle (EV) battery assembly. His foundational work centers on the critical challenge of vibration analysis in high-precision robotic systems, directly addressing the manufacturing hurdles of joining metal tabs on rechargeable battery cells. His most-cited paper, "Vibration analysis in robotic ultrasonic welding for battery assembly" (2012, 12 citations), establishes a rigorous framework for collecting and analyzing vibration data during the welding process, ensuring weld quality and system reliability. A closely related study (2012, 8 citations) further validates his approach by demonstrating the capability of an industrial robotic cell to perform ultrasonic welding on battery modules with varying configurations. Together, these contributions have provided essential insights for optimizing robotic path planning and process parameters, directly impacting the scalability and safety of EV battery production. Dr. Choi’s work is a cornerstone for engineers and researchers aiming to integrate robotics into the high-stakes field of energy storage manufacturing.
