Description

Technical Field

[0001] The invention belongs to the technical field of manufacturing electric vehicle charging facilities, in particular to a mobile charging device for electric vehicles. Background Art

[0002] With the depletion of oil resources and the increasing awareness of environmental protection, new energy vehicles are becoming more and more popular. Electric vehicles use electric motors instead of fuel engines, are powered by batteries, and are driven by motors without a gearbox. They have the advantages of energy saving and environmental protection, easy operation and maintenance, reliable operation, and low noise. With the large-scale promotion and application of electric vehicles, the demand for electric vehicle charging has increased significantly, and the application scenarios have become more and more complex.

[0003] At present, the main method of deploying fixed charging or battery swapping stations is to charge or swap batteries for electric vehicles. The construction of fixed charging or battery swapping stations involves many aspects such as urban construction planning, land approval, environmental assessment, roads, and power supply. Therefore, the project establishment and approval procedures are also very complicated. The construction of fixed charging or battery swapping stations takes a long time, occupies a large area, requires huge investment, and is difficult to build in large quantities on urban main roads. At the same time, electric vehicles need to drive to fixed charging or battery swapping stations to charge or replace batteries, which not only wastes energy, but also shortens the effective driving range of electric vehicles, and is extremely inconvenient.

[0004] In actual charging scenarios, in addition to the problem of insufficient charging facilities, there are still many black areas where fixed charging piles cannot be used (such as old communities, scenic spots, highways and other blind spots where fixed charging piles cannot be installed), and this is the pain point of the charging industry.

[0005] Mobile charging vehicles are highly flexible and suitable for many scenarios where charging piles cannot be used. They are free from site restrictions (for example, blind spots such as old residential areas, scenic spots, and highways where power distribution facilities are imperfect and charging piles cannot be installed, as well as emergency rescue and charging of electric vehicles, peak charging periods, and situations where charging pile parking spaces are occupied). Mobile charging vehicles have obvious advantages in increasing the utilization rate of electric vehicles and reducing electricity costs. They can effectively solve the anxiety of electric vehicle range and absorb the excess capacity of fixed charging facilities. Mobile charging is an important part of the electric vehicle charging network and has strong market development advantages. Therefore, with the development of electric vehicles, the scale and demand of mobile charging vehicles will also expand, and the market is promising.

[0006] At present, with the development of electric vehicles and market demand, mobile charging, as an important charging supplement, has been adopted and applied by more and more car companies and new energy vehicle operation platforms, and some service platforms specializing in mobile charging have also begun to appear. However, due to issues such as cost and model, it is not easy to promote and make a profit.

[0007] At present, the main problems of mobile charging are as follows:

[0008] 1. Due to the high equipment procurement and operating costs and slow capital recovery, the electric vehicle mobile charging market is difficult to make a profit. Therefore, most companies would rather be "self-sufficient" than open to the market;

[0009] 2. The mobile charging market is fragmented, requiring large investments but being difficult to operate. Moreover, the mobile charging market is complex and interactive. Whether it is car companies, vehicle operating platforms, charging pile companies, or real estate, they only cover a part of the field. Therefore, it is difficult to determine the operating entity and form a market scale.

[0010] Therefore, there is an urgent need in the art to design a mobile charging device for electric vehicles, which has a compact structure, is flexible and easy to use, and is convenient for being transported to an area where charging is required to charge the electric vehicle alone.
