The future development of electric vehicles is now strictly linked with their batteries. In parallel of the actual research focused on the development of new materials and increase their performances in terms of energy, power, cost, durability and weight, it is necessary to develop ... Read More
This presentation summarizes the digital twin (DT) concept and how it can be implemented in COMSOL Multiphysics®. Concepts such as real and virtual spaces, high-fidelity models, and lightweight models are explained in the context of DTs. Read More
COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... Read More
The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to ... Read More
A design for the thermal management of the media used for packing Li-ion batteries used in hybrid and electric vehicles has been developed. The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, ... Read More
在所有电池系统中，锂氧电池的理论比能量最高，而实际比能量却明显不足。阻碍氧和/或电子传递导致多孔空气电极的有限利用，而实现对电化学和质量传递耦合的定量理解是具有挑战性的。本文首创了一种具有高度一致和可控通道单元的多孔电极，该电极排除了无序孔隙的随机性，从而能够研究控制机制。通过comsol建立了一个动态非均质模型，提供了LiO2的第一个时空分布，揭示了其在有限电子输运下的反向扩散轨迹。实验和模型的协同结合确定了通道尺寸在分为质量，杂交和电子传递控制的机制中的关键作用。对于大孔隙来说，提高Li2O2的导电性和减轻固液界面损伤比增强氧的扩散更为迫切 ... Read More
The COMSOL Application Builder can tie a custom user interface to application-specific Java code. This functionality can be used to automatically coordinate changing model characteristics across multiple model nodes. A simple user interface can therefore allow simultaneous ... Read More
Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ). A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries. Soluble lead-acid flow battery ... Read More
The characterization of Li-ion batteries is a relevant topic due to the recent developments in Electric Vehicles (EV’s) and Hybrid Electric Vehicles (HEV’s) applications. In order to manage these devices, accurate models are required. At NEXT ENERGY a two dimensional cell-level thermal ... Read More
Introduction: The drawbacks of most commercial “advanced battery” solutions are high price, danger, and low recyclability. The most cost efficient, environmental-friendly, and safest solutions so far is based on lead-acid electrochemistry, a proven technology for more than 150 years. Key ... Read More
