What is it about?

In this study, we explored how to predict the lifespan of lithium-ion batteries used in autonomous vehicles. Predicting when a battery will need to be replaced is important for keeping these vehicles running efficiently. There are many ways to estimate battery life, but we focused on a method that uses artificial intelligence, specifically a type of neural network called Long Short-Term Memory (LSTM). We started by testing how different settings in the LSTM model, like the number of processing units and the amount of data it looks at, affect its accuracy. We found that by carefully adjusting these settings, we could significantly improve the model's predictions, reducing the error from 0.2 to 0.03. Additionally, we introduced a new version of the LSTM model that continuously learns from new data. This incremental approach made our predictions even more accurate, improving the model’s performance by nearly 18%. Our research shows that these AI-driven techniques can be very effective for predicting when lithium-ion batteries will need to be replaced, which is crucial for the reliability and efficiency of autonomous vehicles.

Why is it important?

Unlike traditional models, which rely on static data, this incremental approach continuously updates with new information, leading to significantly improved prediction accuracy. Additionally, my study addresses the critical challenge of parameter optimization in LSTM networks, such as fine-tuning the number of hidden nodes and selecting the optimal window size, to prevent overfitting and enhance performance. Given the increasing reliance on autonomous vehicles and the importance of battery longevity, this research offers a cutting-edge solution that is both innovative and highly relevant to current industry needs.
