In this research, we proposed a prediction method for voltage and lifetime of lead–acid battery. The prediction models were formed by three kinds mode of four-points consecutive voltage and time index.The first mode was formed by four fixed voltages value during four weeks, namely M1.
It shows that the strong nonlinearity of the lead–acid battery capacity trajectory puts forward higher requirements for the hyperparameters, and the conventional GPR algorithm cannot effectively fit and map this trend, causing the divergence of prediction results.
Since lead–acid batteries are still the main source of electricity in many vehicles, their life prediction is a very important issue. This paper uses MLP and CNN to establish a voltage decay model of lead–acid battery to predict battery life. First, 10 prediction models are built through 10 data training sets and tested using one test set.
The machine learning model for predicting the voltage of a lead–acid battery is established using CNN and MLP. The rest of this paper organization is briefed as follows: Section “Introduction” provides the introduction to research problems in lead–acid batteries and machine learning.
The research goal is to use a lead–acid battery that is connected in series with six single cells, which is the power source for the electric vehicle. It will be used every day and battery is fully charged at night, and fixed at 8:00 am every Monday to measure the open circuit voltage of the battery after charging.
In this paper, a method of capacity trajectory prediction for lead-acid battery, based on the steep drop curve of discharge voltage and improved Gaussian process regression model, is proposed by analyzing the relationship between the current available capacity and the voltage curve of short-time discharging.
