Storage Systems and Power Electronics: Challenges, New Opportunities and Emerging Trends

Dear Colleagues,

In recent years, the search for sustainable energy solutions has driven significant advances in energy storage systems (ESS). These systems play a key role in improving the efficiency, reliability, and integration of renewable energy sources into modern power grids and in the decarbonization of the transportation sector. Electrochemical energy storage systems have been evolving towards higher energy and power densities over this period, but continue to face difficulties in electric mobility when attempting to replace internal combustion engines both fully and safely. New battery technologies in the post-Li-ion era can overcome these obstacles, among other things, with the help of power electronics, which has become a key technology for the development and optimization of these energy storage systems and an essential tool for improving efficiency and ease of use.

Power electronics facilitate the conversion, control, and management of electrical energy, thus enabling efficient energy transfer, storage, and utilization. Its versatility and adaptability make it indispensable in a wide range of applications, from grid-scale installations to portable consumer devices. However, this is challenging in the field of electric mobility, where innovative developments in power electronics topologies and control strategies can more straightforwardly address critical challenges for the faster integration of electric vehicles in order to replace internal combustion units. Charging time reduction, an increase in the range of autonomy, SOH, and SOC calculation/estimation enhancements, battery lifetime lengthens, the hybridization of storage technologies, as well as the possibility of implementing ad hoc and nonconventional charging and discharging protocols that improve specific battery technology performance are all examples of the main power electronics benefits in this field.

Based on these capabilities, this Special Issue aims to contribute to the improvement of electrochemical energy storage systems through innovative management, methodologies, approaches, and designs that may include, but are not limited to, the following topics:

• Advanced battery management systems (BMS) for electric vehicles
• Nonconventional charging/discharging protocols
• Post Li-ion technologies specific management
• Multi-level converters for energy storage systems
• Hybrid energy storage systems (HESS) integration.
