已知锂电池功率曲线求解荷电状态soc
第一次写博客，我现在已知锂电池功率曲线，要求解soc，按照论文里公式求解最后结果特别奇怪，希望有大神指导下。
我认为求解soc步骤如下
论文中方法为：先确定初始荷电状态，然后对锂电池功率进行积分算出充放电量，然后上述算出的充放电量除以额定容量在加上初始荷电状态便是soc（t）。而我实际求解步骤入下：1.进行积分运算确定最大最小充放电量，进而确定额定容量2.根据设置的最大最小荷电状态（soc最大0.9最小0.1）以及额定容量求解soc(0),3上述算出的充放电量除以额定容量在加上初始荷电状态便是soc（t）。
公式如下
在matlab下的代码以及求出的soc图片
t=[0:1:287];xx= pgonglvqiu’;y = cumtrapz(t,xx,2);
Erate=(max(y)-min(y))/0.8;
soc0=(max(y)*0.1-min(y)*0.9)/(max(y)-min(y));
soc=soc0+ y /abs(Erate);plot(soc)
