The poster presents a methodology to account for thermal effects on battery cells to improve the typical thermal performances in a pack through heating calculations generally performed under the operating condition assumption. The aim is to analyze the issues based on battery thermo ... Per saperne di più
The most common cause of lithium ion battery failure is high temperature. Improper thermal management strategies can contribute to the temperature related premature battery failure. Excessive heat significantly impacts the performance, safety and cycle lifetime of the lithium ion ... Per saperne di più
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. Per saperne di più
Lithium ion battery safety problem has attracted the whole world’s attention essentially after the explosion of Samsung Note 7. This work mainly deals with the study of the generation, characteristics and prevention measures of the battery fire. Firstly, the heat generation rate of ... Per saperne di più
Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental ... Per saperne di più
Fast charging of lithium-ion batteries is critical to commercial application of electrical vehicles (EV). Recharging lithium-ion batteries using standard charging methods usually takes more than one hour which is considerably longer than refueling an internal-combustion-engine (ICE) car. ...

One of the most noticeable effects in loss of performance and capacity of thermal systems is produced by altitude. This causes that the density of a compressible fluid and the atmospheric pressure are considerably reduced, causing a decrease in electrical power and thermal systems. Given ... Per saperne di più
Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... Per saperne di più
Li-ion battery is being used as power source for various applications. Smart battery diagnostics is essential for creating a better control over the energy storage system and cycle life of a Li-ion battery. It is especially required for real time applications, where more power and energy ... Per saperne di più
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 ... Per saperne di più
