In order for charging companies to make the most profit from electric vehicle charging, costs and profits must be optimized. One way of doing so is by optimizing the power flow. For a charging station, power is either flowing in or out. Thus, power is being purchased or sold. The objective of this research is to optimize the profits made from this process. To do so, the average power demanded o...

Recharging decisions for electric vehicles require many special considerations due to battery dynamics. Battery longevity is prolonged by recharging less frequently and at slower rates, and also by not charging the battery too close to its maximum capacity. In this paper, we address the problem of finding an optimal recharging policy for an electric vehicle along a given path. The path consists...

For mobile roaming environment, the mobile uses visiting network’s services, the mobile station and the visiting network must authenticate each other. We propose a new authentication and anonymous channels protocol for roaming mobile communication. Our scheme can securely apply to GSM and CDPD wireless communication system, it’s not only supporting the mobile anonymity but also resolving the ch...

This paper introduces a hardware platform for automated battery changing and charging for multiple UAV agents. The automated station holds a buffer of 8 batteries in a novel dual-drum structure that enables a “hot” battery swap, thus allowing the vehicle to remain powered on throughout the battery changing process. Each drum consists of four battery bays, each of which is connected to a smartch...

Electric vehicle charging stations are essential infrastructure in developing electric vehicles. In order to construct reasonable amount of electric vehicle charging stations with proper locations, a mathematical multi-level layout planning model, which aims at minimizing the initial construction investment and the users’ charging cost simultaneously, is employed in this paper. An improved gene...

The transition to new forms of urban transport, which are environment friendly, efficient, and cost-effective has become a pressing issue modern times. Battery electric buses being deployed worldwide, marking change in public transport planning operations. emergence fast ultra-fast wireless charging for brought about the need processes associated decision-support models their deployment. object...

Electric vehicles (EVs) have the advantages of low pollution, energy consumption, and high efficiency, so they are highly valued by governments, enterprises, consumers. However, promotion use electric is restricted to a certain extent because their limited range. This paper selects vehicle intercity medium- long-distance travel as research object, takes classical flow-capturing location problem...
