Battery Electric Vehicle Powertrain Behavior on a High-Speed Handling Course
摘要
Modeling and simulation are the best ways to understand in-vehicle processes. However, without measurement data, the simulation results are uncertain. This paper presents the measurement and simulation results of an electric vehicle tested in a Zalazone handling course with a dynamic driving style that is not realizable on public roads. For model validation, it is important to have measurements in all the operation ranges of the powertrain system. The results will complement our former results in city, motorway, and mountain driving and help to develop our detailed longitudinal vehicle model. The paper presents how dynamic style is achievable with an older city electric vehicle. It presents the energy transformation in the powertrain system: voltages and currents from the battery to the inverter, speeds and torques from the electric motor to the road. The measurements are recorded from the vehicle’s CAN-BUS. The paper advises on several modeling challenges. Besides, the paper can be a starting point if the aim is to make a detailed model of one or more subsystems. For example, the electric motor’s temperature data is suitable for the development of the thermal model. Besides, the voltage and current results are ideal for high-voltage battery model parameter identification, for instance, in an equivalent circuit model.
