We introduce a new approach to calculate directly the electric current in Born–Oppenheimer molecular dynamics. In this approach the electric current is computed from the adiabatic variations of the Kohn– Sham eigenstates between consecutive time steps. This conceptually straightforward method is fairly efficient and can be easily implemented into existing electronic structure programs. We test ...

With electric vehicles becoming a more attractive alternative to combustion vehicles, they appear as new volatile loads in the low voltage distribution grids. Until now, they are at the best only considered rudimentarily in the planning process. This paper presents the modelling of electric vehicles as agents in a multi-agent simulation environment for planning purposes. Integrating a model of ...

With the growing penetration of the electric vehicles to our daily life owing to their economic and environmental benefits, there will be both opportunities and challenges to the utilities when adopting plug-in electric vehicles (PEV) to the distribution network. In this paper, a thorough analysis based on real-world project is conducted to evaluate the impacts of electric vehicles infrastructu...

In this article, the vibration test standards and general methods for electric vehicle motor control unit are introduced. New conditions proposed based on data collected during actual test. Using output current as electrical load of controller unit, temperature cycle environmental load, a comprehensive method that integrates is proposed. According to method, equipment process on-load determined...

Abstract Electric space propulsion thrusters only produce low thrust forces. For the fulfillment of a mission this implies long thruster runtimes, and entails qualification times on ground. such testing times, ground facility requires vacuum chamber powerful pumping system which can guarantee high over extended under gas load. DLR’s STG-ET is test facility. It has capability for noble gases typ...
