The huge amount of data generated by devices, vehicles, buildings, the power grid, and many other connected things, coupled with increased rates of data transmission, constitute the big data challenge. Among many areas associated with the Internet of Things, smart grid and electric vehilces have their share of this challenge by being both producers and consumers (ie., prosumers) of big data. Electric...
There has been a desirable trend in recent years towards Electric Vehicles (EVs) contributing less air pollution and noise pollution than internal combustion engine vehicle. EV charging/discharging problem brings a new challenge to the power operation and control. In this paper, the charging/discharging problem is modelled by noncooperative game theory, the payoff function of this model not only maximizes...
Plug-in hybrid electric vehicle (PHEV) is a kind of hybrid electric vehicles (HEV) that has a large capacity battery to satisfy the requirement of the distance for commuters. The parallel PHEV has two kinds of power source, internal combustion engine (ICE) and electric motor (EM). To have a superior fuel economy, a control strategy to split the driving power to ICE and EM is important. In this paper,...
In current embedded mobile systems design, the application processor (AP) is often woken up to service interrupts and user requests. However, this kind of wakeups from sleep is very expensive in terms of battery usage. In the observation that the operating system/driver workloads are very light-weight, in this paper we propose the Offload Co-Processor (OCP) SoC architecture. In the OCP SoC design,...
The aircraft obstacle lights on the power transmission towers, which are located at the places without the utility mains, are powered mainly by solar cells and subordinately by rechargeable batteries. The power supply with solar cells and batteries are configured and coordinated according to the weather conditions. The designed power capacities are to keep the aircraft obstacle lighting system uninterruptable...
