Abstract

The invention discloses a system and a method of analyzing energy consumption of an electric vehicle. The system comprises an electric quantity measuring module, a shaft power measurement module, a power acquisition module and a calculation module, wherein the electric quantity measuring module is used for measuring total output electric quantity of a power battery when a test vehicle drives at a preset vehicle speed at a preset ambient temperature; the shaft power measurement module is used for measuring total power absorbed by a driving shaft of a transmission system assembly when the test vehicle drives at the preset vehicle speed at the preset ambient temperature; the power acquisition module is used for acquiring total power absorbed by a chassis dynamometer when the test vehicle drives at the preset vehicle speed at the preset ambient temperature; and the calculation module is respectively connected with the electric quantity measuring module, the shaft power measurement module and the power acquisition module for respectively calculating the transmission system assembly efficiency and the wheel efficiency according to the total output electric quantity of the power battery, the total power absorbed by the driving shaft of the transmission system assembly and the total power absorbed by the chassis dynamometer. Thus, the overall energy consumption and the efficiency of the electric vehicle at the preset ambient temperature and the preset vehicle speed can be effectively analyzed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an energy consumption analysis system and an energy consumption analysis method of an electric vehicle. Background technique [0002] The energy consumption of pure electric vehicles can reflect the comprehensive performance of pure electric vehicles, such as design level and manufacturing level, and can also reflect the internal power loss of pure electric vehicles. However, there is no effective energy consumption analysis method in the related art to test the energy consumption and efficiency of a pure electric vehicle. [0003] Therefore, related technologies need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide an electric vehicle energy consumption analysis system, which can effectively analyze ...
