Abstract

The invention relates to an energy consumption amount experiment calculation method of an increased stroke type electric automobile, which solves the technical problem that in a stroke increasing period, the overlapping of electricity consumption and oil consumption can not determine the accurate energy consumption amount. Through weighting the electricity consumption of a pure electric phase and the oil consumption of the stroke increasing phase, weighting values of two working conditions are subjected to primary weighting to calculate a comprehensive energy consumption rate or convert the electricity consumption into the oil consumption through a formula so as to calculate an equivalent hundred kilometers oil consumption value.

Description

technical field [0001] The invention relates to an experimental calculation method for energy consumption of an extended-range electric vehicle. Background technique [0002] Energy and the environment are necessary conditions for achieving sustainable development. Energy saving and emission control have become problems that the automotive industry needs to solve. However, traditional hybrid electric vehicles still have disadvantages such as high price, low efficiency, and still consume more gasoline / diesel. . [0003] Due to the bottleneck of battery technology, traditional pure electric vehicles cannot make breakthroughs in terms of mileage and cost. Therefore, it is necessary to seek a new model of new energy vehicles. [0004] like figure 1 As shown, the working mode of the system structure of the extended-range electric vehicle is: when the state of charge (SOC) of the battery reaches the predetermined lower limit, the on-board power generation device starts to charge...
