    Design method for thermal management of BEV battery system
    (Giao thông vận tải, 2023) Xuan Mai Pham; Ga Van Bui; Huu Phuoc Nguyen; Le Hoang Phu Pham
    The energy of an electric vehicle (Battery Electric Vehicle - BEV) is stored in the battery and provides energy for the powertrain of the BEV. The battery system is considered the "soul" of electric vehicles, the technology that carries the core value of this green car. The performance of BEVs is highly dependent on the battery packs. When operating on an electric vehicle, a battery pack is subject to different physical impacts. Therefore, the designer must conduct various studies such as research on optimizing the structural strength of battery packs, shock and collision, battery safety, battery cooling and heat management, battery charging, fatigue, system modeling and control problems. This paper presents the effects of temperature on battery performance and the role of the thermal management system. From there, we propose a method to design and calculate the battery system heat and the thermal management system to ensure the requirements for thermal endurance, safety, reliability, and life cycle. On this basis, the designer can build a battery system design process, including battery cell, battery pack, and battery system layout on BEVs. The calculation methods and design of the BEV battery thermal management system are implemented based on the Simcenter software of Siemens.

    Design process of electric vehicle battery system
    (Giao thông vận tải, 2023) Xuan Mai Pham; Van Ga Bui; Huu Phuoc Nguyen; Le Hoang Phu Pham
    Battery Electric Vehicle (BEV) is a major trend among car manufacturers around the world. The battery system is the most important and expensive component providing energy for BEV operation. This paper presents the design and simulation process of the BEV battery system based on the Siemens Simcenter software. This process includes designing and simulating the battery cell, battery packs, and battery system, including calculating the features and the thermal management system to help maintain a stable temperature. This will help improve the output efficiency, charging and discharging efficiency, performance, stability, and safety of the battery system on BEV and is used to evaluate the overall battery system. Furthermore, a complete battery system designed by this process will be connected to a vehicle dynamics model to evaluate performance under specific operating conditions. Based on this process, the designer can optimally incorporate the battery system into the overall design of the BEV.

    Effectiveness of Exhaust Gas Recirculation (EGR) system on reducing NOx pollutants on turbocharged Hydrogen engines
    (Trường Đại học Giao thông vận tải TP. Hồ Chí Minh, 2025-03) Huu Phuoc Nguyen; Duy Nam Ngo; Minh Hien Ngo; Van Chien Pham
    This paper presents a detailed analysis of a six-cylinder, 13.5 L turbocharged hydrogen (H2) fueled spark ignition engine. The engine features direct injection and a low-pressure exhaust gas recirculation (LP EGR) loop. The objective is to demonstrate the engine's performance under various operating conditions using a basic engine control system integrated within the IFP-Engine library of Amesim software. The study successfully highlights the impact of different operating parameters on combustion efficiency and NOx emissions.
