Numerical simulations of heterogeneous structures like battery modules electric vehicles are challenging due to the various length scales involved in it. Even with latest computing technology, it is impossible simulate crash scene full vehicle resolving all scales. Such hurdles have prevented manufacturers understand mechanical response packs scenarios. In this work, problem multiple was solved...

The application of batteries in electric vehicles and stationary energy-storage systems is widely seen as a promising enabler for sustainable mobility the energy sector. Although significant improvements have been achieved last decade terms higher battery performance lower production costs, there remains high potential to be tapped, especially along chain. However, process highly complex due nu...

We present a comprehensive analysis of real smartphone usage during a 6-month study, involving 25 users, and one specific smartphone, the Android G1. The goal of our work is to study the high-level characteristics of smartphone usage, and to understand the implications on optimizing smartphones, and their networks. We present 11 findings that cover general usage behavior, interaction with the b...

This article provides the dataset of both the LiFePO4 type lithium-ion battery (LIB) behavior and the Maxwell ultracapacitor behavior. The dynamic stress test (DST) condition and the urban dynamometer driving schedule (UDDS) condition were carried out to analyze the battery/ultracapacitor features. The datasets were achieved at room temperature, in August, 2016. The shared data contributes to c...

This paper presents the modeling and simulation of a hybrid proton exchange membrane fuel cell (PEMFC) with an energy storage system for use in a stand-alone distributed generation (DG) system. The simulation model consists of fuel cell DG, lead-acid battery, maximum power point tracking and power conditioning unit which is modeled in the MATLAB/Simulink platform. Poor loadfollowing characteris...

In the mobile ad-hoc network, there can exist two categories of terminals, the battery-powered and the outlet-plugged terminals. In this paper, a new scheme for the power-saving of battery-powered terminals in mobile ad-hoc networks is proposed. Based on this scheme, the battery-powered terminals page the tra c with minimum power to the nearest outlet-plugged terminal, and only the outlet-plugg...

Hierarchically structured active materials in lithium-ion battery (LIB) electrodes with porous secondary particles are promising candidates to increase the gravimetric energy density and rate performance of cell. However, there still aspects this technology which not fully understood. Herein, a mathematical model for half cells hierarchically aiming at delivering better insight obtaining deeper...
