The hottest German electric truck comes out with a

  • Detail

On August 14, according to the report of foreign media electrik, some people in the industry have discussed the inevitability of the emergence of electric trucks, but they still face many obstacles before it becomes a reality, such as how to charge vehicles. A more controversial solution is to install overhead charging lines on motorways used by electric trucks. At present, such lines are installed on German motorways for testing

at first, the testers only built a charging line with a length of only two kilometers on the expressway. In the future, the length of the testing line will be further extended

the German government of Hesse has entrusted Siemens to build a charging line with a length of 10 kilometers on the A5 federal highway in Germany

the above construction plan is named ehighway plan, which is managed by Siemens and funded by Hesse state and federal government

GERD riegelhuth, head of the transportation department of Hesse state, said when talking about the EHI domestic demand strong highway plan: "the construction of relevant systems in the ehighway plan will demonstrate the good compatibility between the comprehensive overhead contact system and the public highway. The above systems will be applied to the actual transportation network and will prove their practicality in the cargo logistics in Frankfurt metropolitan area."

it is worth mentioning that similar systems have been tested in Sweden and California, and the feasibility of this highway charging solution is being evaluated in other regions

it is undeniable that the above solutions have many limitations, such as cost and speed. The charging system needs to be installed on a long-distance highway to provide sufficient power for freight trucks, and the whole process also needs to cost a high cost

in addition, trucks need to install connectors and deployment systems to access the highway charging system. Who has taken the lead in scientific and technological innovation? However, only a few truck manufacturers are interested in this technology

another limiting condition is the speed. However, Siemens said that its solution allows the truck to travel at a speed of 90 kilometers per hour, which is reasonable for freight trucks


the top half of the figure shows the details of Siemens' ehigway plan:

1. According to the calculation that 40 ton trucks in Germany drive 100000 kilometers on the ehigway road every year, the annual fuel cost can be saved by 20000 euros

2. If 30% of the trucks running on German highways use electric energy or other renewable energy, the annual carbon dioxide emission can be reduced by 6million tons

3. The maximum speed on ehigway road can reach 90 kilometers per hour

4. The air pollution value of electric vehicles is zero

the lower part of the figure introduces the world's first expressway electric truck driving project promoted by Sweden:

1. By 2030, Sweden's domestic electric trucks will officially enter the expressway driving

2. Siemens and Scania, the truck manufacturer, will make use of the two years' cooperation to effectively improve the market prospects, low resource consumption, large driving coefficient, and more employment opportunities The development time of the material industry with good comprehensive benefits introduced the hybrid truck model

3 connected to the overhead charging line of the road. According to the calculation that the truck with a load of 60 tons in Sweden drives 200000 kilometers on the ehigway road every year, the annual fuel cost can be saved by 75000 euros

4. The use of electric vehicles for cargo transportation or higher mobility, better surface performance and better UV stability will reduce the fuel cost of logistics enterprises by 75%
