The Design Of The Electric Battery Charging System

Abstract The deterioration of the ecological environment, the human life of the earth more and more can not afford to bring science and technology to break the ring。Environmental pollution is a problem that we have to face。 These years, the haze often occurs, the main reason is that the car is not environmentally friendly。 So the people of new environmentally friendly means of transport, electric vehicles have more and more interest。 The electric vehicle is driven by the power battery, and its key technology is charging。 A good charging system will often have a decisive impact on the performance of the use of electric vehicles。

This paper discusses the performance characteristics of lithium ion power battery and the charging mode and so on, and determines the design of the intelligent charging mode。 At the same time, the single-chip microcomputer as the core of control circuit, low cost, the circuit is simple and reliable, easy to adjust parameters, short adjusting time, increase service life of the battery, and can satisfy the complex charging of electric vehicle, good prospects for development, on energy saving and environmental protection type electric vehicle charging design has important significance。

This paper has 16 figures, 5 tables, 22 references。
