Design Of Mobile Energy Management System Based On LPC1768

With the progress of society and the development of the Times,the energy has more and more connection with our daily life and work.Our demands for emerging energy,such as electric power,are increasing because of their characteristics of clean,safe,convenient and portable.Our daily life and work is also increasingly dependent on such energy.The precision management of energy is not conduct during energy consumption,so this generates large waste in energy use and produces great limitation for our daily life and work.Therefor,in order to provide high-quality energy better and more efficient,it is necessary to conduct adequate management for mobile energy.To solve this problem,this paper designs a mobile energy management system realizing the management of mobile energy based on LPC1768.This system is not only can improve the energy efficiency and extend energy use time,but also has some advantages of improving the safety and service life of energy.Firstly,this paper introduces the development history and future prospects of mobile energy.The research status at home and abroad is also mentioned after discussing the characteristics of several different energy management systems.To choose a high efficiency energy storage module,comparing the properties,advantages and shortages of several common mobile energy storage module.Based on this,a mobile energy management system scheme with lithium battery as energy storage module is designed.The scheme includes real-time monitoring of single lithium battery module information,the input control of charging current and voltage,the balance management of battery pack,the display of battery digital and so on.Based on the functions of the above systems,this paper design a hardware platform with the LPC1768 as its main control chip by studying the performance characteristics of lithium battery in Chapter Three.The hardware design of relating circuits,including data acquisition circuit,charging circuit and liquid crystal display circuit,is completed.In the chapter of the design of balance management circuit,after comparing several balance management circuits,the modular-designed inductance equalizing circuit is selected,its drive circuit is designed and the fuzzy control algorithm is also chosen to control the circuit.Then the software of the whole system is designed,including the design of embedded program,the design of battery state detection program,and the design of PWM control program,the design of temperature collection and the design of liquid crystal display.After the development of software and hardware,the software programs and hardware circuit of the energy management system are debugged,the experiment data is handled and theoretically analyzed.Experiments show that the mobile energy management system based on LPC1768 chip can complete the task of energy management,effectively balance the battery cell in the battery pack,improve the working performance of storage unit,guarantee the safety of the energy use,effectively improve energy performance and utilization efficiency.The system can perform distributed management for multi-cell batteries,which can suite different types of battery energy management within a certain range.This system can adapt to various energy demands on different occasions and with different power.Finally,the research work of this paper is summarized and some prospects for the future development of the research are made.
