Customer ServiceThe results show that in both 100% PV and PV-diesel hybrid systems, the use of lead-acid or Li-ion batteries results in different sizing of the economic optimum system. In other words, if the type of battery is changed, to achieve the economic optimum the entire system must be resized.
Moreover, the higher cycling efficiency of the Li-ion battery (95%) compared to the lead-acid (85%) played in favor of the lower need for PV production. Both characteristics are shown in Table 4. In consequence, the decrease in useful storage capacity was less than nominal.
Two possible energy delivery solutions to the EVs, namely the charging stations and the battery exchange stations (BESs) are the focus of research nowadays. In this paper, a new optimal operation approach is proposed for the BESs.
Among them, b is the annual income of a single station, d is the main business cost of a single station, c is the operating expenses of a single station, and 25% is income tax. The core indicator that affects the profitability of a single power exchange station is the utilization rate.
It must be taken into account that the DOD of 90% allowed in the simulations of Li-ion batteries made their useful capacity greater than in lead-acid batteries whose allowed DOD was 80%. Moreover, the higher cycling efficiency of the Li-ion battery (95%) compared to the lead-acid (85%) played in favor of the lower need for PV production.
In both PV and hybrid systems, the choice of the type of battery affected their economic optimum, including not only the lifetime of the battery, but also its capacity and the size of the PV generator. In hybrid systems, it also affected their fuel consumption. Figure 5 shows the battery lifetimes of the optimum systems, both PV (a) and hybrid (b).
