Batteries and Supercapacitors for Electric Vehicles

Cooling and Preheating of Batteries in Hybrid Electric Vehicles

The performance of a hybrid electric vehicle (HEV) depends strongly on the performance of its high-voltage battery pack, which is influenced by temperature. We have been working on thermal management of batteries in HEVs, including cooling and heating issues. In cold temperatures, batteries perform poorly because of high internal resistance; the vehicle may start slowly. The battery may need to...

Advanced Lithium-Ion Batteries for Plug-In Hybrid-Electric Vehicles

In this study, electric-drive vehicles with series powertrains were configured to utilize a lithiumion battery of very high power and achieve sport-sedan performance and excellent fuel economy. The battery electrode materials are LiMn2O4 and Li4Ti5O12, which provide a cell area-specific impedance of about 40% of that of the commonly available lithium-ion batteries. Data provided by EnerDel Corp...

Estimation of State of Charge of Batteries for Electric Vehicles

State of charge (SOC) can be applied in various fields characterized as an important parameter for estimating residual capacity state of battery. It is obtained from current or collected data, such as voltage, current and temperature as well. The accuracy of estimation of SOC of power battery can be essential and premise in designing the battery management system. Researchers in the fields shal...
