论文摘要
充电状态（SOC）和充电/放电电流的速率是与电池相关的重要参数，可以估算其准确的运行时。本文旨在设计一个控制器，该控制器由现场编程的门阵列，背对背连接的DC-DC转换器和基于电阻触摸显示的基于图形用户界面（GUI）组成。控制器估计SOC并执行电池的恒定电流充电或排放。 GUI的实施是输入用户的参考充电/放电电流并显示SOC。该研究深入研究电池，并通过进行混合脉冲功率表征测试获得其内部参数。此外，获得的内部参数是通过产生SOC的扩展卡尔曼滤波器处理的。该控制器在可再生能源系统，电池测试系统，智能住宅能源管理系统和微网格中具有大量应用。
The state of charge (SoC) and the rate of charging/discharging current are the vital parameters associated with a battery by which its accurate runtime can be estimated. This paper aims to design a controller which comprises of a field-programmable gate array, back to back connected dc-dc converters, and a resistive touch display based graphical user interface (GUI). The controller estimates SoC and performs constant current charging or discharging of the battery. The implementation of GUI is to input the reference charging/discharging current from the user and to display the SoC. This research delves into battery and obtains its internal parameters by conducting hybrid pulse power characterization test. Furthermore, the obtained internal parameters are processed through an extended Kalman filter which yields the SoC. This controller has large applications in the renewable energy system, battery testing system, smart residential energy management systems, and micro-grids.
