Improve user convenience: The popularity of charging and swapping stations makes it easier for electric vehicle owners to charge, especially in urban areas and along highways, solving the problem of electric vehicle range anxiety. 2. Improve energy efficiency: Charging and swapping stations can use low-peak electricity prices at night to charge, optimize the load of the power grid, and improve the utilization efficiency of the power grid. 3. Reduce environmental pollution: Electric vehicles emit less greenhouse gases and pollutants than traditional fuel vehicles. The popularity of charging and swapping stations helps reduce urban air pollution and carbon emissions. 4.

The first replacement vehicle set is obtained through the replacement model, and the vehicle set that can be dispatched for power is obtained. Arrange replacement plans for replacement vehicles of different models, manage battery resources scientifically and rationally, reduce unnecessary battery inventory and dispatching costs, optimize operating costs, and improve economic benefits.

[0085] 5. The electric energy distribution method based on dual-mode communication sets a screening circle, uses the screening circle to traverse the execution path, obtains a full-grid screening circle and a standard-reaching screening circle, and obtains a target replacement vehicle when the replacement vehicle first passes through the full-grid screening circle and then passes through the standard-reaching screening circle. Among the target replacement vehicles, a replacement vehicle that responds to assist in dispatching batteries between a full-grid power station and a standard-reaching power station is obtained to obtain a responding replacement vehicle. The responding replacement vehicle loads a full-grid battery at a full-grid power station and loads a standard-reaching battery at a standard-reaching power station. The replacement vehicle is used to transport the full-grid battery to the standard-reaching power station, thereby increasing the battery supply of the standard-reaching power station without affecting the battery supply of the full-grid power station and increasing the battery supply of the standard-reaching power station without affecting the driving power consumption of the replacement vehicle, thereby scientifically and rationally managing battery resources and reducing unnecessary battery inventory and scheduling costs.

[0086] 6. This power distribution method based on dual-mode communication determines the coverage area by setting the coverage circle, and scientifically and rationally plans the distribution of charging and swapping stations, so as to optimize resource allocation.
