Remaining current of energy storage battery

Can energy storage batteries be predicted accurately?

The prediction error of the model proposed in this paper is small, has strong generalization, and has a good prospect for application. In the case of new energy generation plants, accurate prediction of the RUL of energy storage batteries can help optimize battery performance management and extend battery life.

Why should energy storage batteries be forecasted?

Energy storage has a flexible regulatory effect, which is important for improving the consumption of new energy and sustainable development. The remaining useful life (RUL) forecasting of energy storage batteries is of significance for improving the economic benefit and safety of energy storage power stations.

What is battery remaining available energy prediction?

The remaining available energy is a critically priori information for the energy management and the remaining driving range prediction, which is also an urgent problem needed to be solved for electric vehicles. An effective and reliable approach for battery remaining available energy prediction is proposed and verified. 1.

Is Rul forecasting accurate for energy storage batteries?

The remaining useful life (RUL) forecasting of energy storage batteries is of significance for improving the economic benefit and safety of energy storage power stations. However, the low accuracy of the current RUL forecasting method remains a problem, especially the limited research on forecasting errors.

How to predict RUL of energy storage battery?

First, the extracted HIs were normalized. To predict the RUL of the energy storage battery, the first 75% of the data set is utilized as a training set in this research, and the remaining data set is used as a test set.

How is the energy storage battery forecasting model trained?

The forecasting model is trained by using the data of the first 1000 cycles in the data set to forecast the remaining capacity of 1500–2000 cycles. The forecasting result of the remaining useful life of the energy storage battery is obtained. Figure 4 shows the comparison between the forecasting value and the real value by different methods.
