Description

Technical Field

[0001] This utility model relates to the field of intelligent battery swapping technology, and more specifically, to a distributed energy battery swapping cabinet based on mobile vehicles. Background Technology

[0002] With the increasing popularity of light electric vehicles such as electric bicycles and electric tricycles, users' demand for extended battery life is growing, leading to the emergence of traditional centralized fixed battery swapping cabinets. Existing fixed battery swapping cabinets typically adopt a large cabinet structure, which needs to be fixedly installed in places such as shopping mall entrances and residential areas. Installation requires civil engineering work such as ground hardening, drilling for fixing, and connecting to the municipal power grid (220V / 380V AC). In addition, it requires long-term site leasing and coordination with multiple departments such as property management, fire protection, and urban management for approval.

[0003] Practical experience has shown that existing fixed battery swapping cabinets have significant drawbacks: First, they are inconvenient to install and dismantle, requiring reconstruction when relocated, resulting in high costs and poor flexibility; second, they are severely limited by site constraints, with high-frequency demand locations such as school gates and subway station exits often unable to be installed due to fire safety and planning restrictions, leading to insufficient service network coverage density; third, they have high operating costs, with initial power access fees, long-term site rental fees, and premium electricity charges significantly reducing the profitability of the business model. Utility Model Content

[0004] The purpose of this invention is to provide a distributed energy battery swapping cabinet based on mobile vehicles, which has modular expansion capabilities and multi-energy replenishment functions. It is suitable for the mobile and flexible range replenishment scenarios of electric vehicle users and can solve the problems of limited coverage and installation restrictions of traditional fixed battery swapping cabinets.

[0005] The embodiments of this utility model are implemented as follows: This application discloses a distributed energy battery swapping cabinet based on a mobile vehicle, comprising: The cabinet is provided in multiple ways, and each cabinet is provided with at least one battery compartment, a charging management module and a communication control unit. A vehicle adapter installation mechanism is provided on the cabinet, and the cabinet is detachably connected to a mobile vehicle through the vehicle adapter installation mechanism, and the cabinet can be placed independently on the ground. A multi-functional power supply system, electrically connected to the charging management module, can access at least two different types of energy sources to provide charging power to the batteries in the battery compartment; A modular stacking structure is provided on the upper and lower surfaces or left and right sides of the cabinet. Each pair of adjacent cabinets can be detachably connected through the modular stacking structure to form a multi-compartment battery swapping cabinet.

[0006] In a possible implementation, the cabinet has at least two compartments and can be installed in a horizontal or vertical position; the battery compartment is also equipped with an electrical connector and a status indicator LED light. The electrical connector is used to automatically dock with the battery charging interface when the battery is pushed into the battery compartment; the status indicator LED light is used to display the working status of the corresponding battery compartment, wherein the working status includes idle, charging, fault, and swappable battery. In a possible implementation, the vehicle adaptation installation mechanism includes: The quick-locking device includes a mounting plate fixed to the bottom of the cabinet and a mounting base provided on the cargo box platform of the mobile vehicle. The mounting plate is provided with a standardized mounting hole array, and the mounting base is provided with a positioning pin that matches the mounting hole array. A retractable floor extension bracket is hinged to both sides of the bottom of the cabinet. The retractable floor extension bracket is fixed by means of pins, wherein when retracted, it is close to the side wall of the cabinet, and when extended, it forms a four-legged support structure to support the cabinet to be placed independently on the ground. In a possible implementation, the multi-functional power supply system includes a first power supply interface for connecting to the vehicle's own battery power supply, the battery power supply being high / low voltage DC. The cabinet also contains a DC-DC conversion module and an inverter. The inverter is electrically connected to the battery power supply. The DC-DC conversion module is electrically connected to the inverter, the first power supply interface and the charging management module, respectively, and is used to convert the fluctuating DC power of the battery power supply into the stable voltage and current required for battery charging. In a possible implementation, the multi-functional power supply system further includes a second power supply interface for connecting a photovoltaic panel or a wind energy harvesting device; the cabinet is also equipped with an MPPT power control module, which is electrically connected to the second power supply interface and the charging management module respectively, for tracking the maximum power point of the photovoltaic panel or the wind energy harvesting device to efficiently convert electrical energy and deliver it to the charging management module. In a possible implementation, the multi-functional power supply system further includes a third power supply interface for connecting to 220V AC power to charge the battery in the battery compartment. The third power supply interface is electrically connected to the charging management module.

[0007] In a possible implementation, the modular stacking structure includes a mechanical interlocking structure and an electrical connection structure; the mechanical interlocking structure is provided on the upper and lower surfaces of the cabinet, the top surface of the cabinet is provided with a raised guide positioning post and a flange surrounding the positioning post, and the bottom surface of the cabinet is provided with a recessed positioning hole and a groove that mirror the structure of the top surface; wherein, when the upper and lower cabinets are stacked, the positioning post of the upper cabinet is inserted into the positioning hole of the lower cabinet, and the flange is embedded in the corresponding groove; The electrical connection structure is located inside the left and right sides of the cabinet. When the upper and lower cabinets are stacked, the electrical connector at the bottom of the upper cabinet and the electrical connector at the top of the lower cabinet automatically engage, realizing the parallel connection of the power bus and the communication bus.

[0008] In a possible implementation, a main control unit is also included, which is electrically connected to the communication control unit, the charging management module, and the multi-functional power supply system. The main control unit runs a program module, which includes a power management module, a battery management module, a communication module, and a fault diagnosis and safety module. The power management module monitors and switches the energy input of the multi-functional power supply system. The battery management module communicates with the battery management system in the battery compartment to obtain battery health and charge status. The communication module integrates 4G or 5G mobile communication and GPS positioning functions to upload cabinet status, battery information, and location information to a cloud server and receive remote control commands from the cloud. The fault diagnosis and safety module monitors the status of system components, records fault logs, and sends alarms and cuts off the main power supply when a major fault is detected.

[0009] In a possible implementation, the remote control commands received by the communication module include commands to remotely lock or unlock a designated battery compartment. The communication module transmits the commands to the main control unit, which then controls the charging management module to perform the corresponding operations.

[0010] In a possible implementation, the battery management module communicates with the battery management system via Bluetooth or a serial communication port to collect the battery's voltage, current, and temperature parameters in real time. When the parameters exceed a preset threshold, the battery is determined to be abnormal. The battery management module sends a signal to the main control unit, which then controls the charging management module to stop supplying power to the battery and sends an alarm message to the cloud server via the communication module.

[0011] The beneficial effects of this utility model embodiment are: (1) Through the vehicle-adaptive installation mechanism, the battery swapping cabinet can be flexibly installed on electric tricycles, electric trucks and other carriers. It does not require a fixed site or connection to the municipal power grid, thus avoiding the difficulties of property and fire approval. It can be quickly deployed to high-frequency demand locations such as subway station exits, school gates, and business districts to achieve precise "goods find people" service.

[0012] (2) It eliminates the costs of ground hardening, power access construction and long-term site rental for fixed battery swapping cabinets; at the same time, the multi-functional power supply system utilizes vehicle power and photovoltaic energy to reduce dependence on grid power and reduce electricity expenses; the modular stacking structure can expand the storage space as needed, avoiding cost waste caused by "over-construction".

[0013] (3) A single mobile battery swapping cabinet can move between multiple service points with the vehicle (such as moving from the periphery of the community to the business district during morning and evening peak hours), covering a much wider range than traditional fixed battery swapping cabinets; the modular stacking design can be quickly combined into six- or nine-compartment battery swapping cabinets according to regional needs (such as high demand in scenic areas during holidays), flexibly matching power demand.

[0014] (4) The main control unit monitors the battery status (voltage, current, temperature), energy switching and faults in real time through each program module. When an abnormality occurs, it automatically terminates charging and alarms. The communication module uploads the location and cabinet status to the cloud, which facilitates remote management by operators and improves operation and maintenance efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] refer to Figure 1 and Figure 2The distributed energy battery swapping cabinet based on a mobile vehicle 4 in this application embodiment includes a cabinet 1, a vehicle adapter installation mechanism, a multi-functional power supply system, and a modular stacking structure. It can also be further integrated with a main control unit 5 to achieve intelligent control. There are multiple cabinets 1, which adopt a miniaturized design, with two or three compartments as the basic unit. For example, a three-compartment horizontal cabinet 1 has a single compartment width of about 250mm and an overall size of about 305mm×220mm×170mm. The material is metal sheet or high-strength engineering plastic, such as ABS engineering plastic, which can balance strength and lightweight. The cabinet 1 is equipped with a battery compartment, a charging management module 6, and a communication control unit. The battery compartment is also equipped with an electrical connector (such as a spring-loaded charging interface) and a status indicator LED (red indicates fault, green indicates battery swapping). Cabinet 1 adopts a miniaturized basic unit design, adaptable to the limited storage space of vehicles such as electric tricycles and electric trucks (e.g., the width of an electric tricycle's cargo box is typically less than 1m; the miniaturized cabinet 1 can be installed horizontally or vertically), solving the problem that traditional large fixed cabinets 1 cannot be installed on mobile vehicles. The electrical connector inside the battery compartment automatically mates with the battery charging interface when the battery is pushed into the compartment (e.g., spring-loaded connectors eliminate the need for manual insertion and removal), enabling automatic transmission of energy and communication signals, simplifying the user's battery swapping operation, and improving swapping efficiency. Status indicator LEDs intuitively display the battery compartment status (idle, charging, faulty, swappable), allowing users to quickly identify available batteries and facilitating maintenance personnel to troubleshoot faulty compartments, reducing maintenance costs.

[0025] Furthermore, the vehicle-mounted installation mechanism includes a quick-locking device and a retractable floor-mounted extension bracket 3. The quick-locking device consists of a mounting plate (with standardized mounting holes) at the bottom of the cabinet 1 and a mounting base (with positioning pins) on the vehicle's cargo platform. The positioning pins and mounting holes work together to achieve quick positioning and fixation (a latch, clamp, or quick-release buckle can be used for auxiliary locking). The retractable floor-mounted extension bracket 3 is made of square steel tubing and hinged to both sides of the bottom of the cabinet 1. When retracted, it is fixed tightly against the side wall of the cabinet 1 by a latch; when extended, it forms a four-legged support structure. Through the matching of the standardized holes on the mounting plate and the positioning pins, quick positioning and detachable connection between the cabinet 1 and the vehicle's cargo box are achieved (a latch or clamp can be used for reinforcement). This shortens installation or disassembly time, facilitates the rapid transfer of the cabinet 1 between different vehicles, or allows for disassembly and separate use when needed. The retractable floor extension bracket 3, when folded up, fits snugly against the cabinet 1, saving space. When unfolded, it forms a four-legged support, allowing the battery swapping cabinet to be fixed on a vehicle for mobile service or placed independently on the ground (such as temporarily parked at the entrance of a community), expanding its usage scenarios and improving flexibility.

[0026] Multifunctional power supply system: Equipped with three energy access interfaces: a first power supply interface, a second power supply interface, and a third power supply interface. The first power supply interface is used to connect to the battery power of the mobile vehicle 4 (such as a DC48V / 100Ah lithium battery pack of an electric tricycle). The cabinet is equipped with a DC-DC conversion module and an inverter. The DC-DC conversion module can convert the fluctuating DC48V voltage to the stable DC54.6V voltage required for battery charging, and the inverter can convert the vehicle's DC power to AC power for auxiliary power supply. The second power supply interface is used to connect to photovoltaic panels (such as a 200W flexible photovoltaic panel, installed on the top of the cabinet 1) or wind energy collection devices. The cabinet is equipped with an MPPT power control module, which can track the maximum power point of the photovoltaic panel and improve the power conversion efficiency. The third power supply interface is used to connect to 220V AC mains power as a backup energy source. The first power supply interface connects to the DC48V / DC60V battery of the electric tricycle or truck. A DC-DC converter module transforms fluctuating voltage into a stable charging voltage, eliminating reliance on the municipal power grid and allowing the battery swapping station to continuously charge the battery while the vehicle is in motion, ensuring service continuity. The second power supply interface connects to photovoltaic panels or wind power collection devices. An MPPT module tracks the maximum power point, utilizing green renewable energy to supplement the battery and reduce the proportion of mains power usage, thus lowering operating costs and meeting environmental requirements. The third power supply interface serves as a backup energy interface, connecting to mains power when the vehicle's power supply is insufficient or sunlight is inadequate. This prevents the battery swapping station from shutting down due to a single energy source failure, improving system reliability and meeting power supply needs in extreme scenarios (such as continuous rainy days).

[0027] Furthermore, the modular stacking structure includes a mechanical interlocking structure 2 and an electrical connection structure. The mechanical interlocking structure 2 consists of raised guide positioning posts and flanges on the top surface of cabinet 1, and recessed positioning holes and grooves on the bottom surface. When upper and lower cabinets 1 are stacked, the positioning posts insert into the positioning holes, and the flanges embed into the grooves to prevent lateral sliding. The electrical connection structure consists of high-current waterproof electrical connectors (such as aviation plugs) inside the left and right sides of cabinet 1. These connectors automatically engage when upper and lower cabinets 1 are stacked, enabling parallel connection of the power bus and communication bus. When upper and lower cabinets 1 are stacked, the mechanical interlocking structure 2, with its positioning posts inserted into the positioning holes and flanges embedded into the grooves, resists lateral shear forces, ensuring structural stability after multiple cabinets 1 are stacked and preventing cabinets 1 from sliding or tipping over during transportation or use. The electrical connection structure automatically engages when upper and lower cabinets 1 are stacked, enabling parallel connection of the power and communication buses without manual wiring, significantly improving expansion efficiency and reducing the difficulty of large-scale deployment.

[0028] Furthermore, the main control unit 5, as the system control core, is electrically connected to the communication control unit, charging management module 6, and multi-functional power supply system. Internally, it runs power management, battery management, communication (which can integrate 4G / 5G+GPS), fault diagnosis, and safety modules, enabling energy switching, battery monitoring, remote communication, and fault handling. The power management module prioritizes the use of photovoltaic or wind power, switching to vehicle power or mains power when insufficient. It also calculates energy consumption and power generation to achieve intelligent energy allocation, maximizing the use of green energy and reducing energy costs. The battery management module communicates with the battery management system (BMS) via Bluetooth or serial port to obtain battery health status and charge level, monitor voltage, current, and temperature, and terminate charging in case of abnormalities to avoid safety hazards such as overcharging and overheating (e.g., automatic power-off when temperature exceeds 45℃), extending battery life and ensuring battery swapping safety. The communication module uploads the location of cabinet 1, battery status, and compartment information to the cloud, and receives remote commands from the cloud (such as locking or unlocking compartments). Operators can monitor the distribution and operating status of battery swapping cabinets in real time through the cloud platform, enabling "on-demand scheduling" (such as moving low-usage cabinet 1 to high-demand areas). It also supports users in querying the location of nearby battery swapping cabinets via an app, improving user experience. The fault diagnosis and safety module monitors the status of system components (such as charging management module 6 and power supply interfaces), records fault logs, and sends alarms and cuts off the main power supply in the event of major faults (such as short circuits or communication interruptions), reducing troubleshooting time, preventing equipment damage caused by escalating faults, and improving overall system safety.

[0029] The distributed energy battery swapping cabinet based on the mobile vehicle 4 in this application embodiment has the following characteristics: (1) Through the vehicle-adaptive installation mechanism, the battery swapping cabinet can be flexibly installed on electric tricycles, electric trucks and other carriers. It does not require a fixed site or connection to the municipal power grid, thus avoiding the difficulties of property and fire approval. It can be quickly deployed to high-frequency demand locations such as subway station exits, school gates, and business districts to achieve precise "goods find people" service.

[0030] (2) It eliminates the costs of ground hardening, power access construction and long-term site rental for fixed battery swapping cabinets; at the same time, the multi-functional power supply system utilizes vehicle power and photovoltaic energy to reduce dependence on grid power and reduce electricity expenses; the modular stacking structure can expand the storage space as needed, avoiding cost waste caused by "over-construction".

[0031] (3) A single mobile battery swapping cabinet can move between multiple service points with the vehicle (such as moving from the periphery of the community to the business district during morning and evening peak hours), covering a much wider range than traditional fixed battery swapping cabinets; the modular stacking design can be quickly combined into six- or nine-compartment battery swapping cabinets according to regional needs (such as high demand in scenic areas during holidays), flexibly matching power demand.

[0032] (4) The main control unit 5 monitors the battery status (voltage, current, temperature), energy switching and faults in real time through each program module. When an abnormality occurs, it automatically terminates charging and alarms. The communication module uploads the location and cabinet 1 status to the cloud, which facilitates remote management by operators and improves operation and maintenance efficiency.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
