Effective Electrothermal Simulation for Battery Pack and Power Electronics in HEV/EV
نویسنده
چکیده
Thermal management is an important part during the development of a hybrid or electrical vehicle. This concerns several components in the electrical network of a car, the most important being power electronics and a battery pack. Electrothermal simulation is required at the system level in order to choose the best regime that complies with all thermal requirements and an important problem is how one can quickly obtain a compact but accurate thermal model needed at the system level. A methodology based on model reduction is suggested. One starts with an accurate thermal model developed with finite elements (ANSYS Workbench) then reduces the model by means of implicit moment matching (software MOR for ANSYS) and finally couples the reduced thermal model with an electrical model in Simplorer. Three case studies are presented: 1) a Freescale chip with MOSFETs, 2) IGBT converter, 3) a battery pack.

متن کاملCooling 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...
