Equivalent Circuit Model for High-Power Lithium-Ion Batteries under High Current Rates, Wide Temperature Range, and Various State of Charges Vrije Universiteit Brussel
The most employed technique to mimic the behavior of lithium-ion cells to monitor and control them is the equivalent circuit model (ECM). This modeling tool should be precise enough to ensure the system’s reliability. Two significant parameters that affect the accuracy of the ECM are the applied current rate and operating temperature. Without a thorough understating of the influence of these parameters on the ECM, parameter estimation should ...

Advanced Hybrid Battery Thermal Management System for Fast Charging of Electric Vehicles Vrije Universiteit Brussel
In this paper, the advanced hybrid battery thermal management for electric vehicles (EVs) is proposed with coupling of active liquid cooling and passive phase change material (PCM) based cooling. The parametric study involving different PCM melting point, charging rate and cooling strategy are investigated. The battery module temperatures under PCM cooling alone are observed as 34.8, 38.6 and 43.6 °C for charge rate of 2C, 4C and 6C, ...

An Enhanced Phase Change Material Composite for Electrical Vehicle Thermal Management Vrije Universiteit Brussel
Lithium-ion (Li-ion) battery cells are influenced by high energy, reliability, and robustness. However, they produce a noticeable amount of heat during the charging and discharging process. This paper presents an optimal thermal management system (TMS) using a phase change material (PCM) and PCM-graphite for a cylindrical Li-ion battery module. The experimental results show that the maximum temperature of the module under natural convection, ...
Model Development for State-of-Power Estimation of Large-Capacity Nickel-Manganese-Cobalt Oxide-Based Lithium-Ion Cell Validated Using a Real-Life Profile Vrije Universiteit Brussel
This paper investigates the model development of the state-of-power (SoP) estimation for a 43 Ah large-capacity prismatic nickel-manganese-cobalt oxide (NMC) based lithium-ion cell with a thorough aging investigation of the cells’ internal resistance increase. For a safe operation of the vehicle system, a battery management system (BMS) integrated with SoP estimation functions is crucial. In this study, the developed SoP model used for the ...
Experimental and numerical analysis of holistic active and passive thermal management systems for electric vehicles Vrije Universiteit Brussel
Lithium-ion capacitors (LiCs) are commonly used as power sources for electric vehicles (EVs) due to the combined advantages of electric double-layer capacitors (EDLCs) and lithium-ion batteries (LiBs) comprising high energy density, high power density, and long lifetime. However, the performance of the LiCs is susceptible to temperature. Therefore, a robust thermal management system (TMS) is crucial for EVs to operate efficiently and safely. ...
