The Battery Replacement Key Technologies Of Taiyuan Electric Vehicle In Research And Practice

At present, With the country to encourage new energy vehicles, especially electric vehicles, the development of good policy continues to increase,Electric vehicles to promote the application of scale continue to increase,The classification and selection of electric vehicles, the electric vehicle infrastructure planning and construction, and the impact on the power grid are the problems to be faced.Taiyuan is the capital of Shanxi province,By the end of 2013, Taiyuan was listed as the first batch of twenty-eight new energy vehicles to promote the demonstration city.At present,We are now actively promoting the city electric vehicle demonstration work.In this paper, the research and practice of the key technology of electric vehicle charging and switching in Taiyuan city is studied in this paper.First content:The classification of electric vehicles and key technologies of electric vehicles are described. The main performance parameters and charge discharge characteristics of power batteries are analyzed.Second content:Through the analysis of electric vehicle charging technology, the technology of vehicle charging and battery replacement is compared. The influence of electric vehicle charging and switching on the load characteristics of the power system, the influence of the distribution network and the power quality are studied.Third content:The electric car retains the quantity prediction methods for the analysis of charging for electric facilities planning methods, and focus on electric vehicle charging load forecasting are analyzed and studied, after the substitution of daily load data, the simulation results were analyzed and comparison, conclusions are drawn.Fourth content:Based on field investigation and analysis of the advanced city, Xinxiang and Shenzhen, the research on the basis of the previous analysis is carried out, which has been carried out in Taiyuan city.
