Research On The Technology Of Improving The Driving Range Of Blade Electric Vehicle

The range of the continued driving mileage is not only an important indicator of the technical level of blade electric vehicle,but also an important basis the consumers relied on to judge the technical level.In the process of promotion of blade electric vehicle industry,although the government has published a series of preferential policies,but the current short trip range of blade electric vehicles and high prices lead to consumer approval of blade electric vehicles in China is not high.To solve this problem we need to enhance the driving range at the same time taking into account the price.Therefore,how to maximize the improvement of the continued driving mileage within the minimum cost becomes an important research topic many major auto enterprises have carried out.Specifically,the main work of thisdissertation can be summarized as follows:1.Interpretation driving test standard mileage introduce driving range calculation software,built vehicle simulation model,the NEDC conditions into four basic conditions set forth in the calculation method of driving range.2.Simulation of a single variable,such as curb weight,the impact of the tire rolling resistance coefficient and energy recovery strategies and other factors on the driving range,and a method to enhance the driving range.3.verification of the actual vehicle curb weight,such as changing a single variable,the tire rolling resistance coefficient and energy recovery strategy and other factors contribute to the driving range.The purpose and significance of this paper is: analyzing the influence factors of blade electric vehicle continued driving mileage,offering feasible plans for companies to improve the continued driving mileage during the research and development of blade electric vehicle project,making the continued driving mileage of the blade electric vehicle companies produced reach the maximum quality within a controlled cost,and increasing competitiveness of their products.
