Special Issue Information

Dear Colleagues,

At present, the rechargeable battery industry has reported significant growth in the use of battery systems for portable device and power electronics and renewable energy storage applications. Specifically, with great attention on multicell battery string for electric-powered applications, such as electric vehicles (EV), hybrid electric vehicles (HEV), and energy storage systems (ESS), the necessity of the battery management system (BMS) for having high confidence on operational performance in EV, HEV, and ESS have substantially increased together. Therefore, this Special Issue focuses on variable challenges of battery management system considered in electric-powered application. The topics of interest include but are not limited to:

  • Advanced equivalent electrical circuit modeling
  • Electrochemical-based modeling
  • SOx estimation and prediction algorithms
  • Thermal modeling and management system
  • Artificial intelligence (AI)-based BMS
  • Fault diagnosis and detection
  • Remaining-useful life
  • Voltage and SOC equalization
  • Variable issues of second-use battery (retired battery)
  • Variable issues of energy storage system (ESS)
  • New-generation battery
  • Power electronics-based battery charger and fast charging

In this report, a method for estimating pulse power performance according to pulse duration is proposed. This approach can be used for power control logic in an environmentally friendly power generation system such as electric vehicles and an energy storage system (ESS). Although there have been studies on pulse power capability, we are unaware of any publications on the estimation of the magnitude of pulse power according to the power usage time, and the verification of the estimation result. Therefore, we propose a method to predict power performance according to the pulse duration of batteries and supercapacitors that are used in eco-friendly power generation systems. The proposed method is systematically presented using both a lithium-ion battery module with a nominal voltage of 44 V, 11 Ah, and a supercapacitor module with a maximum voltage of 36 V and a capacitance of 30 F.

Cell Voltage Equalizer Using a Selective Voltage Multiplier with a Reduced Selection Switch Count for Series-Connected Energy Storage Cells
Electronics 2019, 8(11), 1303; https://doi.org/10.3390/electronics8111303 - 07 Nov 2019
Abstract
Cell voltage equalization is mandatory to eliminate voltage imbalance of series-connected energy storage cells, such as lithium-ion batteries (LIBs) and electric double-layer capacitors (EDLCs), to ensure years of safe operations. Although a variety of cell equalizers using selection switches have been proposed, conventional [...] Read more.
Cell voltage equalization is mandatory to eliminate voltage imbalance of series-connected energy storage cells, such as lithium-ion batteries (LIBs) and electric double-layer capacitors (EDLCs), to ensure years of safe operations. Although a variety of cell equalizers using selection switches have been proposed, conventional techniques require numerous switches in proportion to the cell count and are prone to complexity. This paper proposes a novel cell voltage equalizer using a selective voltage multiplier. By embedding selection switches into the voltage multiplier-based cell voltage equalizer, the number of selection switches can be reduced in comparison with that in conventional topologies, realizing the simplified circuit. A prototype for twelve cells was built, and an equalization test using LIBs was performed. The voltage imbalance decreased down to approximately 20 mV by the proposed equalizer, and the standard deviation of cell voltages at the end of the equalization test was as low as 10 mV, demonstrating its equalization performance.

Incremental Capacity Curve Peak Points-Based Regression Analysis for the State-of-Health Prediction of a Retired LiNiCoAlO2 Series/Parallel Configured Battery Pack
Electronics 2019, 8(10), 1118; https://doi.org/10.3390/electronics8101118 - 04 Oct 2019

Unfortunately, voltage imbalances between the cells occur repeatedly during discharging/charging.

To recycle retired series/parallel battery packs, it is necessary to know their state-of-health (SOH) correctly. Unfortunately, voltage imbalances between the cells occur repeatedly during discharging/charging. The voltage ranges for the discharge/charge of a retired series/parallel battery pack are reduced owing to the voltage imbalances between the cells. To determine the accurate SOH of a retired series/parallel battery pack, it is necessary to calculate the total discharge capacity using fully discharging/charging tests. However, a fully discharging/charging test is impossible owing to the reduced voltage range. The SOH of a retired series/parallel battery pack with a voltage imbalance should be estimated within the reduced discharging/charging voltage range. This paper presents a regression analysis of the peak point in the incremental capacity (IC) curve from the fresh state to a 100-cycle aging state. Moreover, the SOH of the considered retired series/parallel battery pack was estimated using a regression analysis model. The error in the SOHs of the retired series/parallel battery pack and linear regression analysis model was within 1%, and hence a good accuracy is achieved. Full article
