Technical Field

[0001] This invention belongs to the field of green energy application technology. Specifically, it relates to a green power storage and consumption system that integrates battery swapping technology, mobile energy replenishment, and vehicle-to-grid (V2G) interaction. Background Technology

[0002] In the field of green energy application technology, a unified standard for battery compartment external discharge technology has not yet been established in the market. Furthermore, there is a lack of technical solutions for mutual charging between integrated energy storage battery compartments and motor vehicles, as well as interaction technologies between integrated energy storage battery compartments and the power grid. In addition, the technology for integrated energy storage battery compartments to provide power to electrical load devices is not yet mature, especially in emergency power outages; technologies for providing power support to residential or commercial buildings also need to be developed.

[0003] Therefore, exploring a scheme to charge the standard battery compartment within a charging and battery swapping station using photovoltaic power generation, while simultaneously enabling photovoltaic power generation to supply electricity to the grid, and ensuring the grid can provide power support to the standard battery compartment at night or in emergency replenishment situations, has become a key issue urgently needing to be addressed by those skilled in the art. Furthermore, this scheme also considers how to store low-charge batteries in the standard battery compartment of the charging and battery swapping station for charging, and how to swap fully charged batteries to electric vehicles, while simultaneously achieving the effective integration of battery swapping, mobile replenishment, and V2G green energy storage and consumption systems for electric vehicles in V2V, V2G, and V2L application scenarios. Summary of the Invention

[0004] In view of this, the present invention proposes a scheme for charging the standard battery compartment of a charging and battery swapping station using photovoltaic power generation technology. This scheme not only enables photovoltaic power generation to supply power to the grid, but also allows the grid to supply power to the standard battery compartment of the charging and battery swapping station at night or in emergency power replenishment situations. Furthermore, this scheme allows low-charge batteries to be placed in the standard battery compartment of the charging and battery swapping station for charging, and then the fully charged batteries can be swapped into electric vehicles. This system integrates battery swapping, mobile power replenishment, and V2G green energy storage and utilization functions for electric vehicles in three application scenarios: V2V (vehicle-to-vehicle), V2G (vehicle-to-grid), and V2L (vehicle-to-load).

[0005] To achieve the above objectives, the present invention provides the following technical solution, which mainly includes:

Simultaneously, in the event of an emergency energy replenishment need, the electricity provided by the grid can also charge the charging and battery swapping stations.

[0013] Preferably, in the aforementioned integrated green energy storage and consumption system of battery swapping, mobile charging, and V2G, charging and swapping stations play a key role in replacing low-charge batteries. Low-charge batteries are transported to the charging and swapping stations by transport vehicles for charging, and then replaced with fully charged batteries for vehicle battery swapping or mobile charging.

[0014] Preferably, in the above-mentioned green energy storage and consumption system integrating battery swapping, mobile energy replenishment, and V2G, the fully charged battery will be installed on the required electric vehicle and the integrated battery compartment for energy storage.

[0015] Preferably, in the above-mentioned green energy storage and consumption system integrating battery swapping, mobile energy replenishment, and V2G, the integrated battery storage and energy storage battery compartment has three technical application scenarios, namely V2V, V2G, and V2L.

[0016] Preferably, in the above-mentioned green energy storage and consumption system integrating battery swapping, mobile energy replenishment, and V2G, the V2V refers to the technology of charging electric vehicles from an integrated mobile energy storage warehouse.

[0017] Preferably, in the above-mentioned green energy storage and consumption system integrating battery swapping, mobile energy replenishment, and V2G, V2G is a technology for interaction between the integrated battery storage and power grid.

[0018] Preferably, in the above-mentioned green energy storage and consumption system integrating battery swapping, mobile energy replenishment, and V2G, the V2L is a technology that uses an integrated battery storage and dynamic energy storage module to supply power to the electrical load.

[0019] According to the technical solution of this invention, compared with the prior art, this invention discloses a method for charging a standard battery compartment in a charging and swapping station using photovoltaic power generation technology. This method not only enables photovoltaic power generation to supply power to the grid, but also allows the grid to provide power to the standard battery compartment of the charging and swapping station at night or in emergency power replenishment situations. Furthermore, this invention also involves charging low-charge batteries in the standard battery compartment of the charging and swapping station and then swapping the fully charged batteries into electric vehicles. This invention further realizes the integrated application of battery swapping, mobile power replenishment, and V2G green energy storage and consumption systems for electric vehicles in three application scenarios: V2V (vehicle-to-vehicle), V2G (vehicle-to-grid), and V2L (vehicle-to-load).

[0020] To more clearly illustrate the specific embodiments of the present invention or the prior art, the accompanying drawings involved in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings in the following description are only a few embodiments of the present invention. For those skilled in the art, other possible drawings can be derived based on the provided drawings without creative effort.

[0021] Figure 1 The attached figure is a system flowchart of the present invention. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 The present invention disclosed herein mainly includes:

[0024] Photovoltaics, power conversion systems, power grids, charging and battery swapping stations, low-capacity batteries, fully charged batteries, integrated energy storage battery packs, electric vehicles, and application scenarios and power loads of integrated energy storage battery packs;

[0025] The application scenarios for the integrated power storage battery compartment include:

[0026] S1: V2V;

[0027] S2: V2G;

[0028] S3: V2L.

[0029] To further optimize the aforementioned technical solution, this solution employs photovoltaic power generation technology to distribute the generated electricity. A portion of the electricity is fed into the power grid for grid connection, while the remainder is supplied to charging and battery swapping stations. These stations are equipped with several standardized battery compartments, each capable of accommodating multiple energy storage batteries.

[0030] To further optimize the above technical solution, the charging and swapping station can replace low-power batteries. Low-power batteries are transported to the charging and swapping station by a transport vehicle for charging, and then fully charged batteries are transported out. The transport vehicle can place the low-power batteries at the charging and swapping station for charging, and then the fully charged batteries can be taken out from the standardized battery compartment of the charging and swapping station and installed on the required electric vehicle.

[0031] To further optimize the above technical solution, the fully charged battery can be installed on the required electric vehicle and the integrated battery compartment for energy storage.

[0032] To further optimize the above technical solution, the integrated power storage battery compartment has three technical application scenarios: V2V, V2G, and V2L.

[0033] To further optimize the above technical solution, the V2V technology is a technology where an integrated energy storage and battery compartment charges an electric vehicle. This technology transfers energy from the integrated energy storage and battery compartment to the battery of another electric vehicle via a charging gun. This process involves two methods: DC charging and AC charging. AC charging technology is limited by the performance of the on-board charger and typically has lower charging power, similar to V2L technology; while DC charging technology represents a high-power V2V technology.

[0034] To further optimize the above technical solution, V2G is an advanced technology that enables bidirectional interaction between the integrated energy storage battery module and the power grid. This technology allows the integrated energy storage battery module to absorb electrical energy when the grid load is low and release the stored energy when the grid load is high, thereby achieving optimal energy allocation and maximizing economic benefits. Specifically, when the grid is under low load, the integrated energy storage battery module can automatically absorb electrical energy for charging; conversely, under high grid load, the battery module can feed the stored energy back to the grid to alleviate grid pressure and obtain corresponding economic benefits. If V2G technology is widely applied, each integrated energy storage battery module can be regarded as a miniature energy storage and power supply unit, achieving dynamic balance of grid load through intelligent control.

[0035] To further optimize the above technical solution, the V2L technology is a solution that integrates power storage in the battery compartment to supply electrical energy to external loads. This technology allows the electrical energy from the power battery to be transferred to other devices, such as lighting fixtures, fans, and electric barbecue grills, enabling electric vehicles to output power to third-party devices. Specifically, V2L allows electric vehicles to function as portable power sources, providing power to various electrical devices in outdoor environments, such as for outdoor barbecues.

The application of battery swapping technology for light trucks significantly improves the efficiency of cold chain logistics, ensuring temperature control of fresh food during transportation and achieving true "cold" and "fresh" results. Furthermore, this technology is also significant for the transportation of special items requiring strict temperature management (such as medicines), effectively avoiding the waiting time caused by traditional charging methods, thus preventing items from becoming invalid or losing effectiveness due to time-sensitivity issues.

[0041] 5. Mobile charging technology (V2V) can significantly alleviate the shortage of charging facilities in highway service areas during holidays, thus having a positive impact on people's well-being.

[0042] 6. V2L technology enables electric vehicles to provide power to various electrical load devices (such as lighting equipment, electric cooking appliances, etc.) in outdoor environments without power access.
