[0009] As a further improvement of the present invention, the power consumption units include power consumption for construction machinery, mobile charging units for electric vehicles, emergency power supplies, power transmission in mountainous areas and other power consumption scenarios.

[0010] As a further improvement of the present invention, a plurality of different integrated charging and swapping modules are installed according to different power usage scenarios.

[0011] As a further improvement of the present invention, different large amounts of electricity can be configured according to different needs and the adaptation of different voltage platforms can be met by lengthening the wheelbase of the power transmission vehicle.

[0012] The present invention solves the problem that many types of electric engineering machinery currently have no space for arranging large power batteries; the problem that many types of electric engineering machinery currently cannot work normally on unpaved roads due to the heavy weight of the power batteries they carry; the problem that many types of electric engineering machinery currently cannot work normally and continuously due to the small power capacity of their own power batteries; the problem that they are restricted by the power infrastructure and must access charging facilities to recharge; the problem of emergency power generation using fuel generators that are noisy, polluting, and uneconomical and cannot be moved over long distances; the problem that it is difficult to set up basic power facilities in some mountainous areas and power cannot be supplied in a short period of time; and the problem of flexible power usage scenarios such as film and television shooting.

It can meet the needs of fast charging and fast battery swapping at battery swap stations. According to different needs, different large capacities can be configured by lengthening the wheelbase of the power transmission vehicle and meeting the adaptation of different voltage platforms.

[0015] At the same time, the present invention can realize power transmission in different scenarios to different integrated charging and swapping modules by the power switching unit, and can also realize mobile power transmission of the power transmission vehicle. Because the whole vehicle system of the power transmission vehicle only communicates with one of the integrated charging and swapping modules, it can avoid a series of problems such as shortened battery capacity and life, high heat generation of the battery body, etc. due to different consistency of battery capacity of different integrated charging and swapping modules.
