Based on the analysis of Fig. 6, we determined the optimal number of chargers to be 22. The average queuing time is 2.216 min, meeting the maximum acceptable queuing time standard. The charging station's loss rate is 4.109 %, and the total construction cost is 4,997,048 CNY.
The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %. After five years of operation, the charging station has saved 5.6610 % on electricity costs.
Like a car battery, you should warm up the battery every so often to keep it active before it becomes dormant. You can recharge it at any time, however, we recommend that you do not let the battery level drop down below 20%. It is recommended to operate and recharge it if necessary every three months to keep the power station active.
The annual operational cost of the charging station is calculated by adding the costs of power and other expenses. Finally, the total operating cost of the charging station is obtained from the fixed construction cost and the annual operating cost. Fig. 1. The overall flowchart of the model.
Through a comparison of the electricity costs of two different operating modes, it is found that charging stations using the shared strategy with energy storage facilities can significantly reduce electricity costs, thereby decreasing the annual operational costs of the charging station.
Queue times are also decreased by optimizing the number of chargers using the M/M/s/K queuing model. The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %.
