Description

Technical Field

[0001] This utility model relates to the field of vehicle battery swapping technology, and more specifically, to a battery swapping system. Background Technology

[0002] Currently, battery swapping has become an efficient way to replenish energy for new energy vehicles. Its principle is to replace the vehicle's battery box with the battery box in the swapping station. Typically, the battery box's electrical interface includes two charging communication ports and two discharging communication ports. The charging communication port consists of a charging port and a first communication port, while the discharging communication port consists of a discharging port and a second communication port. Simultaneously, the base of the swapping station has a corresponding replenishment communication port, which includes two replenishment ports and two third communication ports; the vehicle's base has a corresponding power extraction communication port, including two power extraction ports and two fourth communication ports. When the battery box is assembled with the swapping station base, the charging port and the replenishment port are electrically connected, enabling the swapping station to charge the battery box; the first communication port and the third communication port are electrically connected, enabling data communication during charging. When the battery box is assembled with the vehicle base, the discharging port and the power extraction port are electrically connected, allowing the battery box to supply power to the vehicle; the second communication port and the fourth communication port are electrically connected, enabling data transmission during power supply.

[0003] However, while attempts were made to reduce manufacturing costs by integrating the charging and discharging ports into a single charging / discharging port, enabling the interface to perform both charging and discharging functions, the battery box iteration process from the old model to the new model was hampered by the fact that the battery swapping station base and the vehicle base could not be simultaneously compatible with both the old and new battery boxes. Separate designs were required for the old and new battery boxes, making it difficult to achieve the original goal of reducing costs through battery box improvements. This prevented the full realization of the cost advantages brought by the improved battery box and became a key issue restricting technological development and cost control. Utility Model Content

[0042] In the field of battery swapping technology for new energy vehicles, the compatibility between the base support components and battery modules within a battery swapping station presents technical challenges. Traditional base support components for battery swapping stations typically only accommodate a single type of battery module. When multiple battery modules with different structures and electrical connection methods exist, such as the first battery module 30 and the second battery module 40, a separate base support component needs to be designed for each type of battery module if the traditional method is used. For example, the first battery module 30 includes a first battery unit 31 and a third connecting unit 32, while the second battery module 40 includes a second battery unit 41 and a fourth connecting unit 42. Their internal connection structures, module settings, and electrical connection interfaces all differ, making it difficult for conventional base support components to simultaneously meet the electrical connection and functional compatibility requirements of different battery modules. This results in battery swapping stations needing to be equipped with multiple base support components, which not only increases manufacturing and maintenance costs but also limits the versatility and application scope of the battery swapping system, failing to meet the demand for efficient battery swapping of diverse battery modules within the same battery swapping station.

[0043] This embodiment discloses a battery box, such as Figure 7 , Figure 8 , Figure 9 As shown, the first base assembly 10 may include a first base unit 11 and a first connecting unit 12. The first connecting unit 12 may include a first housing 121, a first charging module 122, a second charging module 123, and a third charging port 124. The first housing 121 can be connected to the first base unit 11. The first charging module 122, the second charging module 123, and the third charging port 124 can be connected to the first housing 121 respectively. With this structural arrangement, the first base assembly 10 can serve as a basic component connecting the first battery assembly 30 and the second battery assembly 40 within the battery swapping station. The first base unit 11 provides a supporting foundation, and the first connecting unit 12 on the first connecting unit 12 provides interface conditions for power transmission and data interaction. This allows the first base assembly 10 to be installed within the battery swapping station to replenish power to the first battery assembly 30 and the second battery assembly 40, realizing the power replenishment function of the battery swapping station for the battery assembly and solving the basic connection problem of power transmission between the battery swapping station and the battery assembly.

[0044] like Figure 10 , Figure 11 , Figure 12As shown, the first battery assembly 30 may include a first battery unit 31 and a third connection unit 32; the third connection unit 32 may include a third housing 321, a third charging module 322, a fourth discharging module 323, a fifth charging port 324, and a fifth discharging port 325; the third housing 321 may be connected to the first battery unit 31; the third charging module 322, the fourth discharging module 323, the fifth charging port 324, and the fifth discharging port 325 may be connected to the third housing 321 respectively; the third charging module 322, the fourth discharging module 323, the fifth charging port 324, and the fifth discharging port 325 may be electrically connected to the first battery unit 31 respectively. This configuration enables the first battery assembly 30 to have a charging and discharging function. The third outer shell 321 protects and fixes the third charging module 322, the fourth discharging module 323, the fifth charging port 324, and the fifth discharging port 325. The third charging module 322 and the fifth charging port 324 can be charged, and the fourth discharging module 323 and the fifth discharging port 325 can be discharged. Through these structures and connections, it is possible to ensure that when the first battery assembly 30 and the first base assembly 10 are connected, power transmission and some signal data exchange can be achieved. This ensures that when the battery swapping station replenishes the first battery assembly 30 through the first base assembly 10, the station can continuously obtain the current temperature and power status of the first battery assembly 30, preventing the first battery assembly 30 from overheating and improving charging efficiency. This solves the problem of charging, discharging, and data exchange between the first battery assembly 30 and the battery swapping station.

[0045] like Figure 4 , Figure 5 , Figure 6As shown, the second battery assembly 40 may include a second battery unit 41 and a fourth connection unit 42. The fourth connection unit 42 may include a fourth housing 421, a first charge / discharge module 422, and a second charge / discharge module 423. The fourth housing 421 may be connected to the second battery unit 41. The fourth housing 421 may be the same as the third housing 321, thus reducing manufacturing costs. The first charge / discharge module 422 and the second charge / discharge module 423 may be connected to the fourth housing 421 respectively. The first charge / discharge module 422 and the second charge / discharge module 423 may be electrically connected to the second battery unit 41 respectively. This structural design enables the second battery assembly 40 to have integrated charging and discharging functions. The fourth housing 421 serves to protect and fix the first charge / discharge module 422 and the second charge / discharge module 423. The first charge / discharge module 422 and the second charge / discharge module 423 can realize charging, discharging, and data transmission functions. With this structural setup, when connected to the first base assembly 10, high-voltage electricity can be transmitted to replenish power, while low-voltage electricity can be used to transmit communication data, allowing the battery swapping station to continuously obtain the current temperature and charge status of the second battery unit 41 through the second base assembly 20. This prevents the second battery assembly 40 from overheating and improves charging efficiency, thus solving the problems of charging, discharging, and data interaction between the second battery assembly 40 and the battery swapping station.

[0046] The battery swapping system may include a first state and a second state. The first state may include a first base unit 11 abutting against a first battery unit 31, a first outer shell 121 and a third outer shell 321 being detachably connected, a first low-voltage port 1222 of a first charging module 122 being electrically connected to a seventh low-voltage port 3232 of a fourth discharging module 323 to transmit some communication data via low voltage, a second charging module 123 being electrically connected to a third charging module 322 to transmit high voltage, and a third charging port 124 being electrically connected to a fifth charging port 324 to transmit both high voltage and low voltage. The high voltage is used to replenish the first battery unit 31 with power, and the low voltage can be used to transmit another part of the signal data, allowing the battery swapping station to continuously obtain the current temperature and charge status of the first battery unit 31 through the first base assembly 10, preventing the first battery assembly 30 from overheating and improving charging efficiency. In the first state, the battery swapping station can charge the first battery assembly 30 through the first base assembly 10. The second state may include the first base unit 11 abutting against the second battery unit 41, the first outer shell 121 and the fourth outer shell 421 being detachably connected, the first charging module 122 and the first charging / discharging module 422 being electrically connected and capable of simultaneously transmitting high-voltage and low-voltage electricity, and the second charging module 123 and the second charging / discharging module 423 being electrically connected and capable of simultaneously transmitting high-voltage and low-voltage electricity. High-voltage electricity allows the battery swapping station to replenish the second battery unit 41's power through the first base unit 11. The first charging module 122 and the first charging / discharging module 422 can transmit some communication data via low-voltage electricity, and the second charging module 123 and the second charging / discharging module 423 can transmit another portion of communication data via low-voltage electricity. This allows the battery swapping station to continuously obtain the current temperature and charge status of the second battery unit 41 through the second base assembly 20, preventing overheating of the second battery assembly 40 and improving charging efficiency. In the second state, the battery swapping station can charge the second battery assembly 40 through the first base assembly 10. By defining these first and second states, the different connection methods and electrical connections between the first base assembly 10 and the first battery assembly 30 and the second battery assembly 40 are clarified. In the first state, the first base assembly 10 can support the first battery assembly 30, transmit power, and interact with data; in the second state, the first base assembly 10 can support the second battery assembly 40, transmit power, and interact with data. This configuration allows the first base unit 11 to be compatible with both the first battery assembly 30 and the second battery assembly 40, reducing the manufacturing cost of the battery swapping station.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 3As shown, the battery swapping system may also include a second base assembly 20; the second base assembly 20 may include a second base unit 21 and a second connecting unit 22; the second connecting unit 22 may include a second outer shell 221, a first discharge module 222, a second discharge module 223, and a third discharge module 224; the second outer shell 221 may be the same as the first outer shell 121, which can reduce production costs; a fourth outer shell 421 may be connected to the second base unit 21; the first discharge module 222, the second discharge module 223, and the third discharge module 224 may be connected to the fourth outer shell 421 respectively. By setting the second base assembly 20 and its included second base unit 21 and second connecting unit 22, the second battery unit 41 can be supported and fixed; the first discharge module 222, the second discharge module 223, and the third discharge module 224 in the second connecting unit 22 are respectively connected to the fourth outer shell 421, fixing the relative positions of the first discharge module 222, the second discharge module 223, and the third discharge module 224. The first discharge module 222, the second discharge module 223, and the first charging module 122 can be identical. "Identical" can mean identical in appearance but different in specific function, which can reduce manufacturing costs. The second base assembly 20 can be installed on the vehicle to fix the relative position of the first battery assembly 30 and the second battery assembly 40 to the vehicle.

[0048] The battery swapping system may also include a third state; the third state may include the second base unit 21 abutting against the first battery unit 31, the fourth housing 421 being detachably connected to the second housing 221, the fifth low-voltage port 2242 of the third discharge module 224 being electrically connected to the sixth low-voltage port 3222 of the third charging module 322, the fourth discharge module 323 being electrically connected to the first discharge module 222, and the second discharge port 2231 of the second discharge module 223 being electrically connected to the fifth discharge port 325. In the third state, the first battery assembly 30 may supply power to the vehicle through the second base assembly 20. The electrical connection between the fifth low-voltage port 2242 and the sixth low-voltage port 3222 can transmit low-voltage electricity to transmit some signal data; the electrical connection between the fourth discharge module 323 and the first discharge module 222 can transmit low-voltage electricity to transmit another part of the signal data, allowing the vehicle to continuously obtain the current temperature and charge status of the first battery unit 31 through the second base assembly 20, improving vehicle safety during operation. The fourth discharge module 323 is electrically connected to the first discharge module 222 and can transmit high-voltage electricity. The second discharge port 2231 and the fifth discharge port can also transmit high-voltage electricity. The two high-voltage electricity channels can simultaneously supply the electrical energy in the first battery unit 31 to the vehicle through the second base assembly 20, providing driving energy for the vehicle.

[0049] In this embodiment, the battery swapping system may further include a fourth state; the fourth state may include the second base unit 21 abutting against the second battery unit 41, the first discharge module 222 being electrically connected to the first charge / discharge module 422, and the third discharge module 224 being electrically connected to the second charge / discharge module 423. The fourth state may involve the second battery assembly 40 supplying power to the vehicle via the second base assembly 20.
