How to predict capacity trajectory for lead-acid battery?

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.

How do lead acid batteries work in a generator engine?

Lead acid batteries play a vital role as engine starters when the generators are activated. The generator engine requires an adequate voltage to initiate the power generation process. This article discusses three prediction models for estimating the voltage and degradation values based on data-driven methods.

Why do lead-acid batteries deteriorate?

However, the degradation of lead-acid batteries is primarily caused by complex and interconnected chemical and mechanical processes and presents a significant challenge in terms of their performance and lifespan . The ability to predict the level of degradation and remaining battery life is crucial for both performance and economic reasons.

Is the capacity degradation trajectory of a battery linear or nonlinear?

The capacity degradation trajectory of the battery presents strong nonlinear, so the rational quadratic covariance function is selected to map the capacity trajectory nonlinearly, as shown in Equation (12).
