La sostenibilidad de la sociedad va a requerir cambios en las personas, en las organizaciones y en las administraciones públicas. La economía circular se postula como un elemento tractor de ese cambio. Pero, ¿cómo abordar ...

One of the main concerns regarding traditional battery energy storage systems (BESS) is how to solve issues related to cell inhomogeneities. This problem commonly ends up reducing the accessible energy level, especially ...

The aim of this work is to dive into the available energy of different configurations of battery packs, a vital factor when it comes to improving the driving range of electric vehicles. To that end, two different storage ...

Multiphase permanent magnet motors are gaining popularity thanks to their advantages, which include reduced torque ripple, enhanced torque capability, and fault tolerance. However, their modelling and control is more ...

The non-uniform flux density distribution inside magnetic cores leads to increased overall losses when compared to the commonly used uniform flux density assumption. This effect is amplified if rectangular based core shapes ...

This work addresses limitations of the composite improved generalized Steinmetz equation for core loss calculation and presents a more robust definition of the losses. First, the limitations due to extrapolation of the ...

This paper evaluates and compares the performances of non-modular and modular battery systems. The modular architecture consists of several battery modules that are individually controlled by means of their corresponding ...

Battery ageing is one of the main concerns in most battery applications. To reduce this degradation rate, it is key to understand how batteries age. However, the diagnosis of battery ageing is very challenging due to the ...

This paper presents the design and assembly of a 50 kW dual active bridge partial power converter. Due to the reduction in the power processed by the converter, the maximum power observed by the converter is set to 4.7 kW. ...

The ageing of insulation systems in electric machines can compromise partial discharge-free designs. Regularly monitoring insulation health is crucial to prevent unexpected failures. Several authors have proposed health ...
