一个MATLAB/Simulink模型，关于电动汽车动力电池荷电状态（State of Charge，SOC）估计； 包括参数文件、模型文件两种，模型文件分别仿真了110A恒流、110A脉冲和ECE15工况； 建模采用基于PEGV的电池等效模型对SOC进行估计，并且加入了温度修正等。 模型比较简单，原理清楚，适合对电动汽车动力电池SOC的估计有兴趣的初学者参考学习，学习前请阅读2到3篇基于电池PNGV等效电池模型的动力电池SOC估计方面论文，这样对理解模型更有帮助。(A MATLAB/Simulink model, on the electric vehicle power battery State of Charge, SOC estimates Including the parameter file and the model file, the model file simulates 110A constant current, 110A pulse and ECE15 working condition respectively. The SOC model was used to estimate the SOC and the temperature correction was added. The model is relatively simple, the principle is clear, suitable for beginners interested in electric vehicle power battery SOC estimation, it will be better to read 2 to 3 SOC estimation papers about battery PNGV equivalent battery.)

用HOUGH检测直线的时候是两个未知量,因为轴半径和相角可以确定一条直 线，在HOUGH域出现累计最大点就可能是原域中的直线。现在回到圆的检测 上来，确定一个圆需要什么：X坐标，Y坐标，半径三个未知量吧，好了，现在， 你做一个三维空间的HOUGH域，以这三个未知量作为三个轴，现在按照一定步长 进行三重循环，在最内层循环是这样的，X,Y 确定，以不同的半径进行搜索，如 果你的X,Y刚好就是实际图像的X,Y处，半径又搜索到实际真实的半径(The HOUGH detect straight when two unknown amount of axis radius and phase angle can be determined in a straight line, in the HOUGH domain cumulative maximum point may be the straight line of the original domain. Now back to the circle detection up to determine what a circle: X coordinate, Y coordinate, radius three unknowns, now, you do the HOUGH domain of a three-dimensional space, three to three unknown quantity as axis, in accordance with a certain step size triple loop, is such that in the innermost loop, X, and Y determined search for a different radius, If you X, Y, exactly is the actual image of the X, Y, at the radius radius of the search to the actual real)
