电池测试循环的代理模型训练

Application ID: 130291


This app demonstrates the usage of a surrogate model function for predicting the cell voltage, cell open circuit voltage and internal resistance of an NMC111/graphite battery cell undergoing a battery test cycle.

The surrogate function, a Deep Neural Network, has been fitted to a subset of the possible input data values. Five input data values can be set: the current in four segments of the cycle and the initial state of charge of the battery cell. The low computational cost of evaluating the surrogate function allows knobs to be used to interactively combine the input values and predict the cell voltage and internal resistance.

Once a combination of values has been selected, the prediction of the surrogate model can be verified by computing the actual physical Li-ion battery model.
