Estimation of power battery SOC based on improved BP neural network

According to the limitations and shortcomings of BP neural network in estimating the battery state of charge(State of Charge, SOC), such as slow convergence speed and poor generalization, this paper puts forward an improved BP neural network method of battery SOC estimation. Train the improved BP neural network with the experimental data. It compares the trained neural network of SOC with the real values, and uses Matlab to simulate in order to verify the correctness of the algorithm.
