解决了非线性函数的逼近问题,实现了BP神经网络在非线性函数逼近中的应用。得出了信号的频率与隐含点之间，隐含点与函数逼近能力之间的关系——隐含层神经元数目越多。(Solved the problem of nonlinear function approximation, and realized the application of the BP neural network in nonlinear function approximation. Between signal frequency and implicit points are drawn, implied the relationship between the point and the function approximation ability, the more number of hidden layer neurons. )

电动汽车是智能电网的一个重要组成部分，能很好的解决能源紧缺，环境污染等问题。无线充电技术更有利于电动汽车与电网进行互动，更好的发挥动汽车削峰填谷、消纳可再生能源的功能。本文在研究中国电动汽车发展相关政策的基础上，，(Electric vehicle is an important part of smart grid. It can solve the problems of energy shortage and environmental pollution. Wireless charging technology is more conducive to the interaction between electric vehicles and the power grid, so that we can better play the function of cutting the peak and filling the valley, and reusing renewable energy. In this paper, based on the related policies of the development of electric vehicles in China, combined with the characteristics of the electric vehicle wireless charging, based on the statistical data, the first trip mileage of the private electric vehicle is extracted by Monte Carlo method, and the starting charge state of the electric vehicle charging is obtained according to the battery charging characteristics and the vehicle driving habit, and the charging state of the electric)
