Abstract
The article presents methodology for testing the traction parameters of the lightweight two-wheeled electric vehicle on the laboratory stand and in road conditions. The tests have been carried out using MAHA LPS 3000 chassis dynamometer and the supplementary instrumentation designed and made for this purpose. The values of the drive torque and the peripheral speed of the drive wheel have been acquired using the dynamometer’s measurement and registration equipment. At the same time the electric parameters of the electric motor have been measured. In order to simulate the road conditions drive on the chassis dynamometer, the set of parameters has been adjusted using measurements carried out in the real road conditions. For this purpose, during the quasi-dynamic passage of the vehicle at the constant linear speed, on the horizontal road surface and in the ambient conditions similar to those in the dynamometer laboratory the current and the voltage transmitted to the electric motor have been measured. Determining the electric power demand of the vehicle in the aforementioned conditions has enabled to adjust the chassis dynamometer parameters in order to proceed with the laboratory tests in the road conditions simulation mode.
