Special Issue Information

Dear Colleagues,

The rapid development of electric and hybrid vehicles has created a boom for lithium-ion batteries. However, lithium-ion batteries inherently have non-linear dynamic behaviours coupled with electrical, acoustic, and mechanical variations. Furthermore, their dynamic behaviors change with factors such as voltage, current, capacity, temperature, and vibration. These factors make it difficult to model and manage the lithium-ion batteries. Therefore, the intelligent battery management system is very crucial for the safe, reliable, and efficient operation of electric and hybrid vehicles. Although remarkable progress has been made in recent years, to control and manage the lithium-ion batteries accurately during their whole lifespan and practical conditions still remain open issues. This Special Issue focuses on the advanced battery management technologies that could potentially be used in electric and hybrid vehicles. Topics of interest include, but are not limited to, the following:

  • Battery state estimation and remaining useful life prediction;
  • Battery thermal analysis and management;
  • Battery charging strategy optimization;
  • Battery pack balance control;
  • Battery multi-physics field parameter monitoring.

State-of-charge (SOC) estimation is pivotal in optimizing lithium-ion battery management systems (BMSs), ensuring safety, performance, and longevity across various applications. This study introduces a novel SOC estimation framework that uniquely integrates Long Short-Term Memory (LSTM) neural networks with Hyperband-driven hyperparameter optimization, a combination not extensively explored in the literature. A comprehensive experimental dataset is created using data of LG 18650HG2 lithium-ion batteries subjected to diverse operational cycles and thermal conditions. The proposed framework demonstrates superior prediction accuracy, achieving a Mean Square Error (MSE) of 0.0023 and a Mean Absolute Error (MAE) of 0.0043, outperforming traditional estimation methods. The Hyperband optimization algorithm accelerates model training and enhances adaptability to varying operating conditions, making it scalable for diverse battery applications. Developing an intuitive, real-time user interface (UI) tailored for practical deployment bridges the gap between advanced SOC estimation techniques and user accessibility. Detailed residual and regression analyses confirm the proposed solution’s robustness, generalizability, and reliability. This work offers a scalable, accurate, and user-friendly SOC estimation solution for commercial BMSs, with future research aimed at extending the framework to other battery chemistries and hybrid energy systems.

The transition to a low-carbon energy matrix has driven the electrification of vehicles (EVs), yet charging infrastructure—particularly fast direct current (DC) chargers—can negatively impact distribution networks. This study investigates the integration of Battery Energy Storage Systems (BESSs) with the power grid, focusing on the E-Lounge project in Brazil as a strategy to mitigate these impacts. The results demonstrated a 21-fold increase in charging sessions and an energy consumption growth from 0.6 MWh to 10.36 MWh between June 2023 and March 2024. Compared to previous findings, which indicated the need for more robust systems, the integration of a 100 kW/138 kWh BESS with DC fast chargers (60 kW) and AC chargers (22 kW) proved effective in reducing peak demand, optimizing energy management, and enhancing grid stability. These findings confirm the critical role of BESSs in establishing a sustainable EV charging infrastructure, demonstrating improvements in power quality and the mitigation of grid impacts. The results presented in this study stem from a project approved under the Research and Development program of the Brazilian Electricity Regulatory Agency (ANEEL) through strategic call No. 022/2018. This initiative aimed to develop a modular EV charging infrastructure for fleet vehicles in Brazil, ensuring minimal impact on the distribution network. Full article
