摘要

本文重点介绍了一种传统的电池荷电状态估计方法和一种智能的电池荷电状态估计方法的实现和性能比较。经过仔细的研究和文献回顾,我们选择了两种不同的估计方法。第一种方法是线性卡尔曼滤波(LKF),这是一种传统的方法,应用广泛。选择的第二种方法是使用前馈的神经网络。对两种方法的最终结果进行了比较研究,得出结论。两种方法均在MATLAB软件中实现。对于卡尔曼滤波器的实现,建立了Thevenin电路的模型来实现所需的方程。这些方程用于计算卡尔曼增益更新的预测误差。在神经网络中,实现包括训练和测试。采用小批量的方法与Adam优化器一起对网络进行训练。

Performance Comparison of Conventional and Intelligent method of Charge Estimation
This paper focuses on the implementation and performance comparison of a conventional and an intelligent method for estimation of SoC of a battery. Two different methods of estimation have been selected after careful study and literature review. The first method is Linear Kalman Filter (LKF), which is a conventional method, widely in use. The second method selected is Neural network using Feed Forward. The final results of both the methods are compared and studied to draw a conclusion. Both the methods have been implemented in MATLAB software. For Kalman Filter implementation, Thevenin circuit is modelled to achieve the needed equations. These equations are used to calculate the predict the error which the updates the Kalman gain. In Neural networks, the implementation comprises of training and testing. Mini batches have been taken for the training of the network along with Adam optimizer.
