xEV Systems Lab is researching technologies to accurately determine battery health in order to efficiently manage and utilize the batteries that store energy and power electric vehicle motors. Through charge and discharge experiments with batteries installed in actual electric vehicles, we analyze changes in battery health, life degradation, and performance changes. In addition to automobiles, our research focuses on hardware and software technologies for electrifying trucks, snowmobiles, and other special purpose mobility applications.
Major Research Fields
- Develop battery health (SOC/SOH/SOP, etc.) estimation algorithms
- Developing algorithms to estimate and diagnose the health of a used battery
- Battery internal impedance analysis and issue research
- Development of fire prevention technology for electric vehicle battery pack systems
- Development of digital twin-based battery system fire prevention technology
- Development of high safety and eco-friendly battery system for special mobility
Research Activities
- KMU Battery Packaging Research Center. (2022~Present)
- Development of battery diagnostic equipment after use of power regeneration method that can check the remaining capacity and stability. (2021~Present)
- Development of technology to improve cooling performance of electric vehicle battery pack system by applying high thermal conductivity thermal interface material. (2022~Present)
- Development of LTO battery based high-output fast charging utility power pack capable of emergency charging of electric vehicles. (2022~Present)
