Description

Technical Field

[0001] The present invention relates to the technical field of battery swap station construction, and in particular to a movable battery swap station that can be used for hoisting-type battery swapping. Background Art

[0002] Lithium-ion batteries and new energy electric vehicles have gradually matured and developed rapidly in the past decade. Electricity is the main alternative energy source for future automobile transportation, because it can be converted from a variety of clean and renewable energy sources such as solar energy, hydropower, wind energy and nuclear energy, and can also reduce dependence on non-renewable energy sources such as oil. As people pay more attention to the concepts of environmental protection, low-carbon economy and reducing energy consumption, the automobile industry faces increasingly severe challenges due to a series of negative effects such as exhaust emissions polluting the environment and high energy consumption. Compared with traditional fuel vehicles, new energy vehicles can effectively reduce automobile exhaust pollution. From an environmental perspective, the exhaust emissions of new energy vehicles can be reduced by 92%-98% compared with traditional vehicles, thereby realizing the diversification of transportation energy and protecting the environment; from an energy perspective, the global oil crisis is becoming increasingly serious, and the automobile industry is the largest component of energy consumption. The development and use of new energy vehicles effectively solves the problem of heavy transportation energy consumption and achieves sustainable development of a low-carbon economy.

[0003] In recent years, all local governments have clearly encouraged and supported the promotion and use of new energy vehicles. Energy replenishment for new energy electric vehicles can be divided into two modes: plug-in charging and battery replacement. In the plug-in charging mode, there are three main problems: high initial cost of purchasing batteries, long charging time, and low charging safety. In addition, in the plug-in charging mode, the charging load of new energy electric vehicles has significant temporal and spatial randomness, which will have an adverse impact on the operation and planning of the power grid. The battery replacement mode combined with large-scale centralized charging has become another competitive commercial technology model for the current development of electric vehicles. First, this mode can effectively reduce the energy replenishment time of electric vehicles. Second, this mode can centrally manage charging safety and ensure the safety and reliability of the battery system. Third, through a reasonable business operation model and the use of battery leasing, business costs can be effectively controlled, and the traceability of the battery system can be centrally and effectively controlled. Depending on the type of vehicle, the general locations where replaceable battery packs are installed are under the chassis (passenger cars such as sedans and SUVs), on the side / rear of the frame, and above the frame (buses, trucks, mining machinery heavy vehicles, etc.). Different installation methods have different battery replacement methods. For example, the lower chassis generally adopts the bottom lifting type battery replacement, the side / rear of the frame generally adopts the side plug-in type battery replacement, and the upper frame generally adopts the hoisting type battery replacement. The side plug-in type battery replacement and the hoisting type battery replacement are applicable to different scenarios and have their own advantages and disadvantages. Generally speaking, the side plug-in type battery replacement vehicle has a compact structure and the construction investment of the battery replacement station is relatively low; the hoisting type battery replacement vehicle has a strong ability to pass through harsh road conditions and the mechanical investment of the battery replacement station is relatively low.

[0004] Hoisting-type battery swapping is generally used for battery swapping of heavy-duty vehicles or mining machinery. The former generally travels long distances and the routes are not fixed. Although the latter has a relatively closed operating area in terms of space, the construction period is limited in terms of time. It will be transferred after completion, and it is often located in a relatively remote mountainous area, and the construction remains unchanged. Therefore, the fixed-construction hoisting-type battery swapping station is to a certain extent troubled by problems such as limited long-term utilization and the need for regular movement, while the movable battery swapping station can solve the above problems in some aspects. At present, the battery swapping station for passenger cars has a movable design. Since passenger cars can use the chassis battery swapping method, the general idea of ​​the mobile battery swapping station is to build an overall battery swapping container, integrate the charger and the battery swapping pallet in a container prefabricated cabin, and facilitate the overall transportation by road to realize mobile battery swapping. However, for the hoisting-type battery swapping station for replacing large battery packs, the above solutions cannot be used.
