Abstract: At present, the research and development of electric vehicle mainly relies on simulation software such as Curise and CarSim, while the development software AMESim owned by Siemens has advantages in constructing models and simulation of system-level modeling in the field of multi-physics integration. Taking a certain battery electric vehicle as an experimental object, comprehensive consideration the power performance and energy flow of the vehicle, a onedimensional simulation model of the vehicle is constructed by AMESim software, and the key parameters of the parts are calculated and matched to design, so as to get the vehicle power and economy indexes. The reliability is verified by comparing the requirements of the performance indexes with the simulation results, and the results show that the data obtained by the simulation experiment using AMESim software can replace the real vehicle test to a certain extent, providing reliable data for shorten the development cycle of the vehicle.
