Energy storage conversion lab(ESCL)

The field of lithium-ion batteries holds immense potential for large-scale applications, particularly in the automotive and aerospace industries. These batteries offer exceptional chemical and thermal stability, cost-effectiveness, and longevity, making them highly appealing. The successful commercialization of lithium-ion batteries could have far-reaching implications, especially for hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs).

At ESCL, our research focuses on battery management system (BMS) design, with a specific emphasis on both hardware and software aspects. Our expertise spans various domains, including electric vehicles (EV), energy storage systems (ESS), satellites, aircraft, submarines, and more. We strive to develop advanced BMS solutions that optimize battery performance.

A crucial aspect of BMS control is accurately monitoring the state-of-charge (SOC) of the battery. This information is vital in real-world applications as it enables us to assess the battery's remaining lifespan. Knowing the SOC allows us to determine when to halt charging or discharging processes to prevent irreversible internal damage caused by overcharging or overdischarging.

Our research at ESCL encompasses various areas related to BMS design. We focus on developing sophisticated state estimation algorithms to accurately estimate SOC, state-of-health (SOH), state-of-power (SOP), and state-of-energy (SOE). Additionally, we investigate fault diagnosis techniques, cell balancing strategies, fast charging methods, temperature management systems, and remaining-useful-life (RUL) estimations.

Furthermore, we are actively involved in exploring next-generation battery technologies to push the boundaries of energy storage. Our investigations include novel battery chemistries such as vanadium redox flow batteries (VRFB), lithium-air (Li-Air), aluminum-ion (Al-Ion), lithium-titanate (LTO), sodium-sulfur (NaS), and more. By researching these emerging technologies, we aim to contribute to the advancement of energy storage systems.

At ESCL, we also foster a culture of cross-disciplinary research. Our exploratory work in bioinformatics reflects our commitment to integrating diverse fields of study and pushing the boundaries of innovation.
