About the research project

Transportation electrification is a novel green industrial revolution to tackle the transportation emission issues. The booming electric vehicle (EV) industry stimulates the development of onboard rechargeable power battery technologies towards a target of higher specific power & energy, greater safety & reliability, more environmental friendliness as well as increasing affordability. On the other hand, the revolutionary progress in battery technologies also drives the rapid development of the EV industry. In recent years, the lithium-ion battery (LIB) cells are favored by many EV giants including Tesla, General Motors, Honda, Ford, Nissan, BMW, and BYD, etc.... Studies have shown that LIB cells can cycle more than 2000 times during 1C charging and discharging. With the rocketing specific energy and power values of modern battery technologies, the heat generation rates of the power battery packs increase rapidly. Although the theoretical operating temperature range of LIB is from -10 to +50°C, the optimal operating temperature range is 15 to 35°C as recommended in a report by the National Renewable Energy Laboratory (NREL). In addition, the temperature difference between different battery cells within a battery pack should be lower than 5°C. Much research verified that the battery degradation rate and aging phenomenon would be accelerated when the battery temperature was over 50 °C. This is a big challenge for batteries to cope with the extreme ambient temperatures or the abusive heat generations during fast charging/discharging without compromising cycle life and output performance. As a result, to tackle the challenges of extreme ambient temperatures and heat generations during normal or abuse operations, an appropriate battery thermal management system (BTMS) is crucial and necessary to maintain optimal operating temperature range, improve durability, and prolong the life cycle. This project aims to develop and investigate different battery management systems used in EVs and explore the energy platform for thermal management of EVs.
