The Effect of Driver's Behavior and Environmental Conditions on Thermal Management of Electric Vehicles 2020-01-1382
Worldwide projections anticipate fast-growing market share of the battery electric vehicles (BEVs) to meet stringent emissions regulations for global warming and climate change. One of the new challenges of BEVs is effective and efficient thermal management of the BEV to achieve minimal parasitic power consumption and maximal driving range. Typically, the total efficiency of BEVs depends on the performance of the thermal management system which is highly affected by several factors including driving environments (ambient temperature and traffic conditions) and driver's behavior (aggressiveness). Therefore, this paper investigates the influence of these factors on the energy consumption by using a comprehensive BEV simulation integrated with a thermal management system model. The vehicle model was validated with experimental data and a simulation study is performed by using the vehicle model over various traffic scenarios generated from a traffic simulator. Particularly, the aggressiveness of a human driver is emulated by varying parameters in the intelligent driver model.
