Title: Battery Output Voltage Response and State-of-Charge Forecasting Method using Hybrid VARMA and LSTM
Inventor: LIM WANSU
IPC: B60L58/12
Filed: 2019-09-26
Abstract: According to the present invention, a method of predicting an output voltage response and a charge state of a battery by using hybrid VARMA and LSTM includes: a first step wherein a pure vector autoregressive (VAR(p)) model having a delay predicts a battery voltage response and an output current at an early stage by using actual history data including a battery voltage response and a battery output current; a second step wherein a residual value of the pure vector autoregressive (VAR(p)) model is calculated by deducting a predicted value obtained through the first step from an actual value; a third step wherein the residual value obtained through the second step is predicted by using an autoregressive model of the residual value or a vector movement average (VMA) model having a delay (q); a fourth step wherein a predicted value of VARMA(p,q) which is a vector autoregressive movement average model is by adding the residual value of the pure vector autoregressive (VAR(p)) obtained through the third step along with the prediction of the battery voltage response and the output current obtained through the first step; a fifth step wherein a residual value of the VARMA(p,q) is obtained by deducting the predicted value of the VARMA(p,q) obtained through the fourth step from an actual value; a sixth value wherein an LSTM learning model corresponding to a repetitive neural network capable of learning long-term dependance learns to predict the residual value of the VARMA(p,q); and a seventh step wherein the residual value of the VARMA(p,q) predicted through the sixth step is added to the predicted value of the VARMA(p,q). Therefore, the present invention is capable of increasing the accuracy of predicting an output voltage response and a charge state of a battery.
