锂离子电池的充电性能受环境温度影响较大，低温条件下充电极化电压升高充电容量下降的问题一直限制了锂离子电池的发展。本文以电化学反应动力学、质量守恒、电荷守恒和能量守恒为理论基础，利用COMSOL软件建立基于LiFePO4/石墨锂离子电池的电化学-热耦合瞬态计算模型，研究了-5℃、-10℃、-15℃三个低温条件下，锂离子电池充电过程中端电压和正极液相扩散极化电压随SOC的变化规律，并进一步通过提出表征这种极化的变量Pdpe，定量分析了低温条件对正极液相扩散极化的影响，最后通过电解质盐浓度和电解质电流密度分析极化变化的原因 ... Per saperne di più
Brain-Machine Interfaces (BMI) provide a direct communication link between brain and external devices such as speech synthesizers and robotic prosthesis to restore speech and movement in persons affected by Spinal Cord Injuries or neurodegenerative diseases such as Amyotrophic Lateral ...

The EPFLoop team from Ecole Polytechnique Fédérale de Lausanne has developed a capsule thanks to which it won the 3rd place in SpaceX’s Hyperloop Pod Competition in 2018. This year the EPFLoop team has been selected again to participate at the 2019 Competition held at the SpaceX ... Per saperne di più
Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... Per saperne di più

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... Per saperne di più
A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal ... Per saperne di più
The proposed State of Charge (SOC) governed fast charging method for secondary lithium based batteries charges a battery many times faster than the normal Constant Current-Constant Voltage (CC-CV) charging and reduces the side-effects generally accompanied by various fast charging ...
