In view of severe changes in temperature during different seasons in cold areas of northern China, the decay of battery capacity of electric vehicles poses a problem. This paper uses an electric bus power system with semi-active hybrid energy storage system (HESS) as the research object and proposes a convex power distribution strategy to optimize the battery current that represents degradation...

A shared-bus shared-memory multiprocessor based on multithreaded CPUs is evaluated against different solutions for cache and coherence protocols. Multithreaded architectures have been intensively studied for DSM multiprocessors, where memory latencies are a major factor in limiting performance. They can be interesting also for bus-based multiprocessors, since processor speed are increasing at a...

Recently, cooperative control actions of electric vehicle become much more complex than before, it is important and significant to manage and allocate energy by a network in electric vehicle. According to the electric vehicle control requirements, this paper have designed a network architecture based on the vehicle CAN network communication protocol SAE1939, including high-speed network, slow-s...

This paper proposes a methodology for practical siting and sizing of Hybrid energy systems (HESs) consist of: wind turbine (WT), photovoltaic (PV) and combined heat and power (CHP) units. In this method, the interaction of Plug-in Electric Vehicles (PIEVs) in the electric distribution system is considered. Electric Vehicle are seen to have some negative impacts on electric distribution system p...

Now-a-days, as computerization of automotive increases, the need for more/advanced electronic control units (ECUs) is growing. Vehicles are increasingly behaving like computers with wheels. Due to the abundance use of ECUs in cars, electronic system design is becoming complicated day by day. As a consequence, information processing in such complex systems faces interruptions. Therefore, there i...

With shrinking feature size and increasing frequency, power dissipation on data bus has become the most predominant factor than the power dissipation in other parts of the circuitry. The large intrinsic capacitance associated with buses is responsible for a substantial fraction (approx 40%) of total power dissipated, because the bus power dissipation is proportional to switching activity. The m...

Electrohydrodynamic effect on natural convection in horizontal channels is investigated from a numerical point of view. The EHD effect is induced by narrow strip electrodes placed at the bottom wall of the channel. The channel is subjected in a first stage only to the electric forces, and in a second stage to the simultaneous action of a temperature gradient and an electric field. The interacti...
