Description

Technical Field

[0001] This utility model relates to the field of new energy equipment and energy storage technology, specifically a battery swapping cabinet and battery swapping system with a charging port. Background Technology

[0002] With the rapid popularization of new energy vehicles, battery swapping cabinets, as the core equipment in battery swapping systems, are gradually becoming an important facility for solving the range anxiety problem of electric vehicles. Due to the large charging demand of electric vehicle batteries, existing battery swapping stations typically require a separate high-voltage cable connection to charge the batteries within the cabinets. Before constructing a battery swapping station, it is necessary to communicate with the power grid department to assess whether the site is suitable for laying high-voltage cables, and cable laying construction can only proceed after confirmation. However, the site assessment process is time-consuming, and the cable laying and ground repair work further increase construction costs and time investment.

[0003] Furthermore, existing battery swapping stations mostly rely on independent power supply modules to complete the charging function, resulting in complex internal structures and high manufacturing costs. At the same time, the underdeveloped power grid infrastructure in some suburban and remote areas makes laying high-voltage cables more difficult, limiting the promotion and deployment of battery swapping stations. Although charging piles have gradually become more common in these areas, their power resources have not yet been effectively integrated to meet the power supply needs of the battery swapping cabinets.

[0004] Therefore, how to make full use of the existing power resources of charging piles, reduce the time and economic cost of building battery swapping stations, and at the same time improve the flexibility and applicability of battery swapping cabinets has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a battery swapping cabinet and system with a charging port, to solve the problems of long site evaluation time, high construction cost, and complex internal structure of battery swapping cabinets caused by the need for separate high-voltage cable connection for the construction of existing battery swapping stations. By making full use of the power resources of existing charging piles, the construction time and economic cost of battery swapping stations are reduced, while improving the flexibility and applicability of the battery swapping cabinet.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] A battery swapping cabinet with a charging port includes a battery swapping cabinet and a power supply interface module on one side of the battery swapping cabinet. The power supply interface module is used to connect to the charging gun of the charging pile for electrical transmission.

[0008] Furthermore, it also includes a battery storage unit, which is located inside the battery swapping cabinet and is used to store battery packs that are to be charged or have been fully charged;

[0009] A charging management module, which is electrically connected to the power supply interface module and the battery storage unit, is used to distribute the power input from the charging pile and transmit the power to the battery pack in the battery storage unit;

[0010] The control panel is located on the outer surface of the battery swapping cabinet and is used to display the working status of the battery swapping cabinet and receive user operation commands.

[0011] Furthermore, the battery storage unit includes several battery compartments, each of which is equipped with an independent battery fixing device and a conductive connector. The conductive connector is electrically connected to the charging management module for transmitting power to the battery pack.

[0012] Furthermore, the charging management module includes a current distribution unit and a voltage regulation unit. The current distribution unit is used to distribute the power input from the charging pile to each battery compartment as needed, and the voltage regulation unit is used to adjust the output voltage to adapt to different battery pack models.

[0013] Furthermore, it also includes a backup power module, which is electrically connected to the charging management module;

[0014] The backup power module is used to store excess power input from the charging pile and can be used to power the battery swapping cabinet.

[0015] A battery swapping system is also provided, including the aforementioned battery swapping cabinet with a charging port and a charging pile. The charging pile is located on one side of the battery swapping cabinet, and the charging gun of the charging pile can be inserted into the power supply interface module of the battery swapping cabinet with the charging port.

[0016] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The battery swapping cabinet and system provided by this utility model utilize the power resources of the charging pile to charge the battery pack inside the cabinet by setting a power supply interface module on one side of the cabinet.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] Example

[0026] See Figure 3 As shown, the battery swapping system provided in this embodiment includes a battery swapping cabinet with a charging port and a charging pile. The charging pile is set on one side of the battery swapping cabinet, and the charging gun of the charging pile can be inserted into the power supply interface module of the battery swapping cabinet with the charging port.

[0027] like Figure 1-3 As shown, the overall structure of the battery swapping cabinet 1 includes a power supply interface module 2, a control panel 5, a protective cover, and the main internal components, including a battery storage unit, a charging management module, and a heat dissipation system. These modules, through specific connections and spatial distribution, achieve efficient utilization of power resources and optimized functionality of the battery swapping cabinet.

[0028] The power supply interface module 2 is located on one side of the battery swapping cabinet and is used to connect to the charging gun 4 of the charging pile 3. This module includes a plug holder and a conductive contact assembly. The plug holder is a recessed structure used to securely fix the charging gun plug, preventing poor contact due to external vibration or improper operation. The conductive contact assembly, located inside the plug holder, consists of multiple metal conductive plates, corresponding to the positive, negative, and ground terminals of the charging gun plug, respectively. When the charging gun is inserted into the plug holder, the conductive contact assembly directly contacts the metal plates of the plug, forming a stable current path. The power supply interface module 2 is electrically connected to the charging management module via an internal cable, thereby transmitting the power input from the charging pile to the charging management module.

[0029] The charging management module is located inside the battery swapping cabinet, near the power supply interface module, to minimize power loss during transmission. The module includes a current distribution unit and a voltage regulation unit. The current distribution unit is a multi-output circuit that dynamically allocates input power according to the needs of each battery compartment. The voltage regulation unit uses a converter to adapt to different battery pack models, ensuring the output voltage matches the rated voltage of the battery pack. The charging management module is connected to each battery compartment in the battery storage unit via multiple wires, each wire having an independent terminal for mating with the conductive connectors within the battery compartment.

[0030] The battery storage unit is located in the central area of ​​the battery swapping cabinet and consists of multiple battery compartments. Each battery compartment contains an independent battery securing device and a conductive connector. The battery securing device uses a spring-loaded clamping structure to firmly hold battery packs of different sizes while preventing damage to the battery casing due to over-clamping. The conductive connector is installed at the bottom of the battery compartment and mates with the positive and negative contacts of the battery pack to achieve power transmission. The conductive connector is connected to the output terminal of the charging management module via internal wires to ensure that power is accurately transmitted to each battery pack. In addition, each battery compartment also has an indicator light to display the charging status of the battery pack and communicates with the data processing unit of the charging management module to update the status information in real time.

[0031] The battery swapping cabinet's cooling system runs throughout the entire cabinet and mainly consists of a fan assembly and heat conduction channels. The fan assembly is mounted on top of the cabinet and secured to the upper surface with bolts. It includes two axial fans that accelerate airflow and expel heat from the cabinet. The heat conduction channels are a set of metal pipes running through the interior of the cabinet, one end connected to the bottom of the battery storage unit and the other extending to the air inlet of the fan assembly. The inner walls of the heat conduction channels are coated with a high thermal conductivity coating, which quickly absorbs the heat generated by the battery pack during charging and conducts it to the vicinity of the fan assembly, ultimately expelling it outside the cabinet through the fans.

[0032] The backup power module is located at the bottom of the battery swapping cabinet, near the sliding rail assembly. The backup power module includes a battery storage pack and an inverter. The battery storage pack consists of multiple lithium-ion batteries connected in series, used to store excess power input from the charging station. The inverter is connected to the battery storage pack via a circuit board, converting DC power to AC power to power the basic functions of the battery swapping cabinet. When the charging gun is unplugged, the backup power module automatically switches to power supply mode, maintaining the basic operation of control panel 5 and the communication module, and supporting emergency charging of vehicles.

[0033] The slide rail assembly is installed at the bottom of the battery swapping cabinet. Its fixed rail is secured to the ground with expansion bolts, and the movable bracket, through a slider that engages with the fixed rail, can slide freely along the rail direction. The movable bracket is connected to the bottom frame of the battery swapping cabinet by welding, thus enabling the overall movement of the battery swapping cabinet. The design of the slide rail assembly allows the battery swapping cabinet to be flexibly adjusted in position, adapting to different layout requirements, where space permits.

[0034] A protective cover, made of weather-resistant materials such as polycarbonate or fiberglass, covers the outer surface of the battery swapping cabinet. The cover is attached to the cabinet via a snap-fit ​​mechanism, allowing for quick disassembly and installation. The outer surface of the cover is treated with UV protection, effectively resisting direct sunlight and rain, while also providing some impact resistance, protecting the battery swapping cabinet from external environmental influences.

[0035] like Figure 3 As shown, the battery swapping system includes a battery swapping cabinet 1 and a charging pile 3 used in conjunction with it. The charging pile 3 is located on one side of the battery swapping cabinet, and the distance between them does not exceed a preset value to ensure that the charging gun 4 can be smoothly inserted into the power supply interface module 2. The charging pile 3 includes a charging gun 4 and a cable winding device. The charging gun is connected to the power output terminal of the charging pile via a cable. The cable winding device uses a spring rewinding mechanism to realize the cable's storage and release, adapting to the layout requirements of battery swapping cabinets in different locations. A communication module is provided between the battery swapping cabinet 1 and the charging pile 3. The communication module includes a wireless signal transceiver unit and a data processing unit. The wireless signal transceiver unit communicates with the control unit of the charging pile via an antenna to transmit charging status information. The data processing unit parses and processes the transmitted data through an embedded processor and feeds the results back to the control panel.

[0036] In practical applications, after the user inserts the charging gun 3 into the plug holder of the power supply interface module 2, the conductive contact assembly contacts the plug of the charging gun to form a current path, and the power is transmitted to the charging management module through the internal cable. The charging management module dynamically allocates the input power according to the needs of each battery compartment in the battery storage unit, and adjusts the output voltage through the voltage regulation unit to ensure that the power can be adapted to different battery pack models. During charging, the heat dissipation system, through the design of the fan assembly and heat conduction channels, quickly dissipates the heat generated by the battery pack outside the cabinet, avoiding heat accumulation that could affect battery life. When the charging gun 3 is unplugged, the backup power module automatically switches to power supply mode to maintain the basic operation of the battery swapping cabinet 1 and supports emergency charging of vehicles. Users can view the working status of the battery swapping cabinet through the control panel 5 and perform corresponding operations according to the prompts.

[0037] The sliding rail assembly of battery swapping cabinet 1 allows for flexible movement and repositioning when space permits, significantly improving its versatility, especially when layout adjustments or site changes are needed. The protective cover ensures stable operation of the cabinet in harsh environments, extending its lifespan. The communication module enables real-time information exchange between battery swapping cabinet 1 and charging pile 3, allowing users to monitor the cabinet's operating status and perform corresponding operations. The cable winding device design makes the charging gun more convenient to use and adapts to different battery swapping cabinet layout requirements.

[0038] To enable those skilled in the art to better understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of the battery swapping cabinet and battery swapping system is provided in conjunction with specific application scenarios.

[0039] In practical applications, when a user needs to charge the battery packs in the battery swapping cabinet 1, they first insert the charging gun 4 of the charging pile 3 into the plug fixing seat of the power supply interface module 2. At this time, the conductive contact assembly and the metal piece of the charging gun plug make contact to form a stable current path, and the power is transmitted to the charging management module through the internal cable. The current distribution unit in the charging management module dynamically allocates the input power according to the needs of each battery compartment in the battery storage unit, while the voltage regulation unit adjusts the output voltage through the converter to adapt to different battery pack models. During this process, the charging management module connects to the conductive connector in each battery compartment through independent wiring terminals to ensure that the power can be accurately transmitted to each battery pack.

[0040] During charging, the battery pack generates heat. The cooling system effectively addresses this issue through the design of a fan assembly and heat conduction channels. One end of the heat conduction channel connects to the bottom of the battery storage unit, while the other end extends to the air inlet of the fan assembly. The inner wall of the heat conduction channel is coated with a high thermal conductivity coating, which quickly absorbs the heat generated by the battery pack and conducts it to the vicinity of the fan assembly. The fan assembly contains two axial fans that accelerate airflow to expel heat from the enclosure, thereby preventing heat buildup from affecting battery life.

[0041] When the charging gun is unplugged from power supply interface module 2, the backup power module automatically switches to power supply mode. The energy storage battery pack in the backup power module stores excess power input from the charging pile, and the inverter converts DC power to AC power via a circuit board to power the basic functions of the battery swapping cabinet. In this mode, control panel 5 and the communication module can still maintain basic operation, while also supporting emergency charging of vehicles. Users can view the operating status of battery swapping cabinet 1 through control panel 5 and perform corresponding operations according to the prompts.

[0042] The battery swapping cabinet's sliding rail assembly allows for flexible movement and repositioning wherever site conditions permit. The fixed rails are secured to the ground with expansion bolts, while the movable support slides freely along the rails via sliders. This design significantly improves the cabinet's versatility, especially when layout adjustments or site relocation are required. A protective cover, made of weather-resistant materials such as polycarbonate or fiberglass, covers the outer surface of the cabinet, effectively resisting direct sunlight, rain erosion, and external impacts, protecting the cabinet from environmental influences.

[0043] The communication module between the battery swapping cabinet 1 and the charging pile 3 enables real-time information exchange. The wireless signal transceiver unit communicates with the control unit of the charging pile 3 via an antenna to transmit charging status information. The data processing unit parses and processes the transmitted data through an embedded processor and feeds the results back to the control panel 5. This design allows users to easily monitor the working status of the battery swapping cabinet 1 and perform corresponding operations. The cable winding device uses a spring rewinding mechanism to store and release the cable, adapting to the layout requirements of the battery swapping cabinet 1 in different locations, making the use of the charging gun 3 more convenient.

[0044] As can be seen from the implementation steps of the above specific application scenarios, the battery swapping cabinet and system provided by this utility model utilize the power resources of the charging pile 3 to charge the battery pack, eliminating the need for separate high-voltage cables and significantly shortening the construction cycle and cost of the battery swapping station. Simultaneously, the design of the backup power module ensures that the battery swapping cabinet 1 can maintain basic functionality even after the charging gun 4 is removed, enhancing the system's flexibility and reliability. The design of the heat dissipation system and protective cover further improves the stability and service life of the battery swapping cabinet, while the application of the slide rail assembly and communication module enhances the equipment's applicability and user experience.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
