Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a rechargeable and replaceable wheeled Al mobile vehicle. Background Art

[0002] With the increasing popularity of new energy vehicles, recharging electric vehicles has become a critical issue for the industry, leading to increasing demand for charging piles. The existing charging method relies on the car looking for a charging pile, which often results in fully charged vehicles or unrelated vehicles occupying charging spaces. The emergence of mobile rechargeable and swappable carts transforms this "car looking for a charging pile" model into a "pile looking for the car," significantly improving charging flexibility and alleviating the shortage of charging spaces.

[0003] The new energy vehicle industry is developing rapidly, with China becoming the world's leading consumer of electric vehicles. This growth is expected to continue in the coming years, leading to the retirement of a large number of heavy-duty truck battery packs for battery swaps. At the same time, demand for low-cost, high-performance batteries is increasing in areas such as energy storage and low-speed vehicles. The cascade utilization of retired battery packs can meet some of this market demand and holds broad market prospects.

[0004] Heavy-duty truck battery swap packs typically have high energy density and good performance, and even after retirement, they still have a certain amount of residual capacity and usability. For example, when the battery capacity drops below 80% and is no longer able to power an electric heavy-duty truck, it can be used in scenarios with relatively low power requirements, such as energy storage systems and low-speed electric vehicles, to maximize resource utilization and improve resource recycling rates.

[0005] On the one hand, battery manufacturers and heavy-duty truck operators can tap into the residual value of retired battery packs through cascaded utilization, reducing battery procurement and disposal costs. On the other hand, the development of the cascaded utilization industry can also create new economic growth points, driving the development of related industrial chains such as battery testing, disassembly, reassembly, and remanufacturing, providing more employment opportunities and economic benefits to society. Summary of the Invention

The vehicle dispatching system can realize point-to-point tracking control, vehicle path planning, vehicle grouping dispatching, driving mode switching, task management, and multi-vehicle task planning.

[0014] After the vehicle body is connected to the external charging station, the vehicle places an order through the cloud platform and controls the automatic navigation driving assistance components on the chassis by wire.
