[0056] The battery housing 20 is a closed structure with good protective performance, and contains multiple battery packs 40. These battery packs 40 are connected in series or parallel via conductive connection structures within the housing, allowing for flexible adjustment of output voltage and capacity according to different power requirements. The battery packs 40 are standard-sized modules with a detachable design, facilitating modular installation, replacement, and management. They also support the replacement of non-operating battery packs during operation, preventing the vehicle from losing power and significantly improving the vehicle's range and operational efficiency.

[0057] Multiple charging guns 60 are also installed inside the carriage 10 to provide charging services to external devices or vehicles.

The high-voltage power distribution unit 50 is responsible for combining and distributing the high-voltage electricity output from multiple battery packs, and its output terminals are connected to multiple charging guns 60 to achieve parallel power supply. Meanwhile, the control unit is located inside the carriage 10 and communicates with the battery pack 40, battery management system (BMS), power distribution unit, and each charging gun 60. It centrally monitors and intelligently schedules the power supply status and can intelligently select a single battery pack for power supply or allocate multiple battery packs in combination to provide power based on the load-side power demand, achieving a flexible and efficient energy distribution strategy.

[0058] This embodiment also supports a "1+N" combined discharge mode, where "1" represents the vehicle's original onboard power battery, and "N" represents multiple energy storage battery packs 40 within the vehicle compartment. All batteries used are of uniform specifications and possess advantages such as high consistency, good safety, numerous charge / discharge cycles, and convenient maintenance. In some high-power output scenarios, multiple battery packs 40 can be connected in parallel to drive a single charging gun 60, achieving "many-to-one" power supply and meeting special usage requirements such as high-current fast charging.

[0059] The high-voltage power distribution unit 50, as a core power management component, not only achieves unified convergence and isolation control of multiple battery packs 40, but also provides safe and efficient power supply paths for multiple charging guns 60 through independent output channels, reducing line interference and fault risks, and improving the overall operational stability of the system. The control unit integrates a communication module, enabling wireless connection with external servers or mobile terminals to achieve remote scheduling, real-time battery status uploading, and discharge control command issuance, providing support for building an intelligent operation and maintenance platform. Furthermore, the vehicle can also be expanded with safety auxiliary modules such as cooling systems and fire warning systems according to application scenarios, improving environmental adaptability and operational reliability.

[0060] In terms of structural design, the carriage 10 features three opening methods: left-side opening, right-side opening, and rear-side opening. This differs from existing structures that only support single-side or rear-side opening, significantly improving the flexibility of loading and unloading operations, equipment maintenance, and operation. Functional components such as the battery box 20, battery pack 40, high-voltage power distribution unit 50, and charging gun 60 are all organically integrated within the carriage 10.

The high-voltage power distribution unit and control unit work together to support efficient distribution control of multiple charging guns, meeting the application needs of multiple devices simultaneously using power or multiple vehicles charging simultaneously, and possessing good scalability and safety control capabilities. This solution is applicable to various mobile power supply scenarios, such as emergency power supply, construction power supply, and rapid vehicle recharging, improving the system's versatility, reliability, and economy.

[0062] In this embodiment, it should be noted that, in addition to the first battery rack 30 and the second battery rack 31, the system may also include a third battery rack, a fourth battery rack, and so on. These subsequent battery racks are arranged hierarchically in a similar manner, each housed within the hollow area of ​​its superior battery rack.

The tray 33 is equipped with a locking mechanism to fix its position after the tray is pushed in / pulled out, preventing accidental sliding during use or maintenance.

[0072] This structure not only facilitates quick replacement of the battery pack, but also improves the safety and stability of the battery pack inside the battery box, making subsequent maintenance easier.

[0073] The technical solution implemented in this embodiment achieves modular and hierarchical installation and management of the battery pack through a multi-layer battery rack and sliding rail tray design. The cooperation between the sliding rail and the locking mechanism ensures that the battery pack remains stable during transportation and maintenance, reducing operational risks. The pull-out tray design significantly improves the disassembly efficiency of the battery pack, facilitating quick replacement and maintenance. Overall, it improves the space utilization, maintenance convenience, and safety performance of the mobile power supply vehicle's battery system.

[0074] Furthermore, slide rails 34 are provided on both sides of the first battery rack 30 and the second battery rack 31, and the slide rails 34 cooperate with the guide structure inside the battery box 20; the first battery rack 30 and the second battery rack 31 are pivotally connected to the end of the support frame 35; the support frame 35 includes a telescopic rod structure, which includes a sleeve and a rod that can extend and retract within the sleeve, and a locking hole is provided on the sleeve or the rod.

[0075] In this embodiment, it should be noted that slide rails 34 are provided on both sides of the first battery rack 30 and the second battery rack 31.

The guide structure ensures the stability and accuracy of the sliding process and avoids the battery rack from deviating or getting stuck during sliding.

[0076] Optionally, each layer of the battery pack is equipped with a quick-change mechanism (a forklift arm insertion groove that allows for easy insertion or removal of the forklift arm without damaging the battery pack or other components). Specifically, the quick-change mechanism includes a forklift arm slot structure located at the bottom of the battery pack or on the pallet rack. The slot is sized to match a standard forklift arm, allowing the forklift to be directly inserted into the groove to perform a pull-out operation of the battery pack or pallet.

[0077] Optionally, the battery rack 30 is provided with battery slots 31 of different sizes to accommodate external battery packs 40 of different sizes and specifications.

This power distribution control box integrates electrical protection and control components such as contactors, relays, and / or fuses. The power distribution control box is used to manage the output circuit of the high-voltage power distribution unit 50 and the power supply circuit of each charging gun 60.

[0090] The control unit connects to contactors or relays within the power distribution control box via signal lines, enabling dynamic control of the on / off states of each output circuit based on charging demands. This achieves safe and effective management of the high-voltage power distribution system and charging guns. Simultaneously, protective components such as fuses ensure timely power disconnection in abnormal conditions, preventing equipment damage and safety accidents.

[0091] The technical solution implemented in this embodiment, through the integration of a power distribution control box, achieves centralized control and protection of the high-voltage power distribution unit and multiple charging gun circuits, thereby improving the system's safety and intelligence level. The control unit's precise control of contactors and relays enables flexible management of multiple circuits, supports concurrent charging of multiple devices while ensuring power supply safety, and adapts to complex and ever-changing operating environments.

[0092] Furthermore, the battery pack 40 is a battery pack and is equipped with a battery management system; the battery management system is used to monitor the voltage, current and temperature parameters of each individual cell in real time and send the monitoring data to the control unit.

[0093] In this embodiment, it should be noted that the battery pack 40 is a standardized battery pack, which integrates multiple battery cells and achieves safe and stable energy storage through structured packaging. Each battery pack 40 is equipped with a dedicated Battery Management System (BMS).

[0094] The battery management system (BMS) monitors the voltage, current, and temperature parameters of each individual cell within the battery pack in real time, ensuring that the battery operates within a safe operating range. The monitoring data is transmitted to the control unit inside the vehicle via a communication interface, enabling centralized management and early warning of the battery status. The BMS is also responsible for equalization charging, overcharge protection, over-discharge protection, and abnormal temperature alarms, ensuring the performance and lifespan of the battery pack.

[0095] The technical solution implemented in this embodiment employs a battery pack equipped with a battery management system to achieve real-time monitoring and safety management of the battery status. By feeding back key parameter data to the control unit, the safety and reliability of the mobile power supply vehicle's battery system are improved, preventing risks such as overcharging, over-discharging, and overheating, ensuring stable power supply and extended service life.

[0106] When the sensor detects abnormal smoke concentration or temperature exceeding the preset threshold, the control unit responds promptly, triggering the automatic fire extinguishing device to release the extinguishing agent. At the same time, it can cut off the power output of the battery pack to prevent the fire from spreading.

[0107] In addition, the control unit can issue alarm signals to remind operators to handle abnormal situations in a timely manner and ensure the safe operation of the mobile power supply vehicle.

[0108] The technical solution implemented in this embodiment centrally manages the fire early warning system through a control unit, enabling rapid identification and automatic handling of fire hazards. Signal connectivity ensures the system's real-time response capability and reliable execution, effectively improving the safety protection level of the mobile power supply vehicle.

[0109] In one optional embodiment, all functional modules of the mobile power supply vehicle 100 (battery housing 20, high-voltage power distribution unit 50, control unit, charging interface, etc.) adopt a detachable modular design and are connected via standard interfaces. The battery housing 20 supports complete cabinet replacement, and the power distribution box and control unit use a plug-in wiring method for easy and quick maintenance or replacement.

[0110] The technical solution implemented in this embodiment, through modular and standard interface design, enables rapid disassembly and replacement of each functional unit, significantly improving the system's maintenance convenience and scalability. This solution adapts to different maintenance needs and application scenarios, ensuring the long-term stable operation and flexible upgrades of the mobile power supply vehicle.

[0111] In one alternative embodiment, the battery housing 20 is equipped with intelligent temperature control sensing system components, including highly sensitive air conditioning, air cooling and liquid cooling, and explosion-proof devices.

[0112] In this embodiment, it should be noted that the battery housing 20 integrates an intelligent temperature control sensing system. This system includes a high-sensitivity temperature sensor, an air conditioning unit, an air-cooling system, a liquid-cooling system, and an explosion-proof safety device. The temperature sensor monitors the temperature changes inside the battery pack 40 and the battery housing 20 in real time, and feeds the data back to the control unit to achieve precise temperature control. The air conditioning unit, in conjunction with the air-cooling system, forms an airflow channel through a fan to enhance air convection and quickly reduce the surface temperature of the battery. The liquid-cooling system uses a coolant circulation and heat exchange structure to provide efficient direct contact cooling of the battery pack, adapting to high loads or extreme temperature environments. The explosion-proof device, as a safety guarantee, can automatically activate in case of abnormal temperature rise or malfunction, preventing battery thermal runaway and explosion risks, and ensuring the safe operation of the entire vehicle.

[0113] The technical solution implemented in this embodiment enables dynamic temperature management of the battery pack 40, maintaining the battery within a safe and stable temperature range, and significantly improving battery life and performance stability. Multiple cooling mechanisms work together to meet heat dissipation requirements under different operating conditions and adapt to various complex environmental conditions. Simultaneously, the explosion-proof device effectively prevents safety hazards and enhances the system's safety protection capabilities. Overall, the introduction of the intelligent temperature control sensing system significantly improves the reliability and safety of the large mobile power supply vehicle, ensuring continuous and stable power supply services and meeting the needs of high-intensity operations and diverse applications.

[0114] The following is a specific application scenario of this application: In the operation of shared two-wheeled electric vehicles in cities, battery swapping stations typically need to efficiently store and quickly replace a large number of standardized batteries. This patent is mainly applicable to the battery storage box for two-wheeled electric vehicles, which has multiple independent compartments for placing batteries and a discharge function. Operators can quickly remove depleted batteries and replace them with fully charged ones, enabling immediate replenishment of the vehicle's power. Simultaneously, when there is a temporary power demand in the area where the battery swapping station is located, the batteries inside the box can also supply power to other equipment through the discharge function, ensuring emergency power supply. This application scenario not only improves the operational efficiency and range of two-wheeled electric vehicles but also expands the emergency power supply value of energy storage systems, making it suitable for promotion and use in cities, industrial parks, and remote areas.

[0115] The embodiments described above are merely illustrative of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
