Problems solved by technology

[0005] Third, if the half-way charging method is used, since its installed capacity is much larger than that of ordinary passenger cars, even if the fast charging method is used, the charging time will take at least 2 hours, which will seriously affect the transportation efficiency
[0006] Fourth, if the method of battery replacement (that is, replacement of power batteries) is adopted, due to its complex technology, poor safety, and low efficiency, it cannot be widely used

Embodiment 1

[0032] A method for transporting electric tractor semi-trailers. A service area is selected on a highway transportation route, and one or more charging parking spaces and charging facilities for electric tractors are set in the service area; The first electric tractor performs connected charging. After the semi-trailer towed by the second electric tractor starting from the starting point or the service area of ​​the previous station, after a period of transportation, the electric tractor is replaced by the first electric tractor that has been fully charged in the service area. Enter the second electric tractor with low battery in the service area. The replaced first electric tractor tows the semi-trailer for continuous transportation and runs to the destination or the service area of ​​the next station; while the replaced second electric tractor with insufficient power conducts charging operations in the service area to serve the next shift. The electric traction semi-trailer...

Embodiment 2

[0034] Such as figure 1 : There is a charging facility 1 in the selected service area, and the electric tractor 2 of No. Arrive at the service area and enter the service area to replace the electric tractor, such as figure 2 : Replace the No. 2 electric tractor 3 with insufficient electric power in the service area by the No. 1 electric tractor 2 that has been fully charged in the service area; image 3 : The replaced No. 1 electric tractor 2 tows the semi-trailer for continuous transportation and transports to the service area of ​​the next station. At this time, the replaced No. 2 electric tractor 3 with insufficient power is charged on the charging bay of the charging facility 1 The operation is to prepare for the replacement of No. 3 electric tractor 4 for the electric traction semi-trailer that comes to the service area in the next class. At present, the construction of expressways in our country is becoming more and more perfect, and the distance between service areas...

Abstract

The invention discloses a transportation method for electric traction semitrailers. The transportation method for the electric traction semitrailers comprises the steps that a service area is selected on a highway transportation line, one or a plurality of charging parking spaces or charging facilities are arranged in the service area, and an electric tractor parked in each charging parking space is charged in advance; after the electric traction semitrailers (semitrailer group) starts from the starting place or the last station service area and arrives at the service area after a period of transportation, changing operation of the tractors is conducted, and the tractors with low battery are replaced by the tractors which are fully charged; after the changing operation of the tractors is finished, the semitrailers are pulled to run continuously by the tractors which are fully charged, and the replaced tractors with low battery are charged in the service area, so that tractor changing for the next group of traction semitrailers is well prepared. Whole-process-electrification of long-distance highway transportation is achieved in a relay transporting mode. By implementing the transportation method for the electric traction semitrailer, manufacturing and operating cost can be reduced significantly, transportation operating efficiency and safety of line transportation are improved, and great energy-saving and environmentally-friendly benefits are generated.

Description

technical field [0001] The invention relates to the field of tractor transportation, in particular to a transportation method for an electric traction semi-trailer, and is especially suitable for expressway transportation and logistics industries. Background technique [0002] Traction semi-trailer transportation has become the main mode of road transportation in my country and even in the world. At present, the vast majority of tractors in the world use fuel engines as power, and their oil consumption and emission pollution are very huge. In recent years, new energy technology has developed rapidly in the field of city buses, passenger cars, and special vehicles, but it has developed slowly in long-distance road transportation. Some new energy companies have cooperated with heavy-duty tractor manufacturers to develop electric tractors, taking the first step towards realizing green and environmentally friendly road transportation. However, the current electric tractors hav...
