Abstract
The fast increase in adoption and development of Electric Vehicles (EVs) has invited a significant challenge to the existing charging management techniques and infrastructure. It is necessary to efficiently manage a large number of mobile EVs. As compared to fuel and gasoline type vehicles, the EV has a limited driving range and needs to recharge its battery frequently during long journeys. Hence, with plug-in charging services one major concern is the long duration of battery recharging. In this paper, we employ heterogeneous BS (Battery Switching) technology to provide an alternative charging option to minimize the charging duration of EV. Furthermore, enabling BS reservation in a centralized manner for mobile EVs, load balancing algorithm and optimal selection of Battery Switching Station (BSS) across the network are proposed. In addition, we suggest a scheduling technique for depleted batteries to recharge effectively in BSS to minimize power loss and queuing time at selected BSS. We have conducted a performance evaluation by comparing the proposed scheme with other benchmarks, in terms of average trip duration, total trip energy consumption, etc. Finally, it is proven that the battery stock is managed across the network efficiently through the proposed scheme.
Highlights
Electric Vehicles (EVs) refers to a vehicle that is powered by electric energy
As we discussed in the global planning phase in the previous section, when EV Status Of Charge (SOC) is below the minimum threshold, EV will be finding Battery Switching Station (BSS) regarding the swap of a depleted battery with a full charge battery
In request contain information the arrival time (Art) can be quite random because of the mobility uncertainty such as traffic jams and road accident, EV may cant reach to switching station on time
Summary
EV refers to a vehicle that is powered by electric energy. Normally, an EV can be charged from an external energy source and discharged to an external energy source via a wall socket. A lot of countries have pledged millions and billions of dollars to fund the development of EV to replace conventional vehicles with EVs. According to studies from the Center of Solar Energy and Hydrogen Research, the total number of EVs in the global market was 740,000 in early 2015. In the automated switch platform, switching between a depleted battery from an EV and a fully charged battery is performed. The depleted battery is placed and recharged so that it can be used by other requested vehicles. This indicates that each BSS can maintain several batteries for switching.
