Description

technical field [0001] The invention relates to a vehicle power system, in particular to an electric vehicle power system. Background technique [0002] In the early stage of electric vehicle research and development, precisely designing the power system and coordinating the performance of each sub-component to make them match well can tap the potential of existing electric vehicle technology and improve energy efficiency. Statistics and analysis of driving conditions play an important role in the design of electric vehicles. To match the power system of an electric vehicle, it is first necessary to determine the operating conditions of the vehicle. On the basis of the analysis of the working conditions, the parameters of the power system are matched according to the proposed vehicle dynamic index, and then computer simulation is used to analyze the parameter matching results. Verify and propose optimization schemes. The power system in the prior art has complex structure ...
