Description

Technical Field

[0001] This application relates to the field of charging, and more particularly to a mobile power supply vehicle. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the number of new energy vehicles in China has surged. However, this is accompanied by a continuous decline in the traditional auto repair industry. Data shows that the number of repair shops has plummeted from 901,000 to 626,000 in the past four years, leaving many employees facing pressure to transition to other jobs. Meanwhile, pure electric vehicles face a series of new problems in daily use, most notably "frequent fast charging leading to battery depletion" and "power outages causing vehicle breakdowns." The widespread occurrence of these phenomena has made emergency charging and roadside assistance services for electric vehicles a major concern for users. With my country's energy security needs and energy legislation policies further liberalizing power generation, transmission, distribution, and sales, and increasing vehicle-to-grid interaction and vehicle-to-load power supply requirements, this mobile power supply vehicle is suitable for various power supply scenarios and is becoming increasingly common.

[0003] Traditional roadside assistance primarily relies on towing services, which are costly (typically exceeding 300 yuan per trip) and their response efficiency is limited by urban traffic control and road restrictions, resulting in a poor user experience. While some regions have experimented with introducing mobile power supply vehicles for emergency charging, most mobile power supply vehicles on the market currently use a simple assembly model of a "fuel vehicle chassis + external charging module," with their core function limited to basic charging and lacking fine-grained management and control of battery status. These products exhibit the following prominent problems during use:

[0004] Limited functionality and poor scalability: Existing power supply vehicles are mostly high-power mobile power sources that can only complete simple energy transmission and cannot flexibly switch between different power and interface standards, making it difficult to meet the energy replenishment needs of various types of electric vehicles.

[0005] High maintenance costs: Fuel-powered vehicles not only increase operating costs but also increase energy consumption and pollution emissions; in addition, most of their batteries are non-replaceable, and once the power is exhausted, they need to be returned to the warehouse for recharging, which often takes more than 2 hours, resulting in low rescue efficiency.

[0006] Lack of intelligent management: Most equipment does not integrate high-voltage power distribution units, wireless communication modules, or intelligent control systems, making it impossible to achieve modern operational functions such as remote dispatching, accurate user billing, and real-time power monitoring. The business model is rigid and difficult to promote on a large scale.

[0007] Based on the above problems, there is an urgent need for a new mobile power supply vehicle solution with high integration, intelligent management capabilities and modular battery replacement mechanism. This solution can not only respond quickly to emergencies such as power outages in electric vehicles, but also reduce rescue service costs, improve equipment operation and maintenance efficiency, and promote the transformation and upgrading of the new energy after-sales service system.

[0055] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] Please refer to Figure 1 - Figure 9One embodiment of this application provides a mobile power supply vehicle 100, including: a carriage 10; a battery cabinet 20 disposed within the carriage 10, with an integral positioning and disassembly structure between the battery cabinet 20 and the carriage 10; a battery rack 30 disposed within the battery cabinet 20, the battery rack 30 including multiple mounting positions 31, each mounting position 31 for detachably accommodating a battery pack 40; multiple detachable battery packs 40 disposed within the battery cabinet 20, with series and / or parallel connection structures between the multiple battery packs 40; multiple detachable battery packs 40 disposed within the carriage 10, the multiple battery packs 40 being configurable for series and / or parallel connection; multiple charging guns 60 disposed within the carriage 10; a high-voltage power distribution unit 50, with its input end connected to the multiple battery packs 40 and its output end connected to the multiple charging guns 60, distributing electrical energy to the circuits of the charging guns 60; and a control unit disposed within the carriage 10.

[0058] In this embodiment, it should be noted that the battery pack 40 adopts a detachable design, which facilitates quick replacement or maintenance. The battery capacity and configuration can be flexibly adjusted according to actual usage scenarios, preventing the vehicle from ceasing service due to depletion of power, thus improving range and operational efficiency. The batteries support series or parallel connections, which can meet the needs of high-voltage fast charging scenarios and adapt to the power supply requirements of different power levels, enhancing the compatibility and adaptability of the entire vehicle.

[0059] Especially when multiple battery packs are used for power supply, the control unit can achieve intelligent allocation: based on the load conditions at the electrical load end, it automatically determines whether to use only a single battery pack or schedule multiple battery packs to supply power simultaneously. It also supports a "1+N" combined discharge mode, where "1" represents the vehicle's original power battery and "N" represents multiple energy storage battery packs in the vehicle body. All of the above batteries use vehicle power batteries of uniform specifications, which have advantages such as good consistency, high safety, long cycle life, and convenient maintenance. The control unit also supports replacing other non-working battery packs while one battery pack is supplying power, thereby improving the continuity and flexibility of operation and maintenance.

[0060] In certain high-power applications, multiple battery packs 40 can be connected in parallel to drive a single discharge gun 60 based on real-time voltage and current requirements, achieving a "many-to-one" high-power power supply mode. This effectively meets special needs such as emergency fast charging or power supply for industrial equipment. Furthermore, the battery pack 40 supports multiple voltage levels for external discharge output, including but not limited to 110V, 220V, 380V, and 450V. Through series connection of multiple battery packs, the voltage can reach up to 1200V or even higher, expanding the application range.

[0061] The high-voltage power distribution unit 50 is used to uniformly manage the power output of multiple battery packs 40. Through internal electrical control logic, it distributes the power to the circuit where each charging gun 60 (or discharge gun) is located, ensuring the independence and safety of each output channel and effectively reducing line interference and system failure risks.

[0062] As the core management module of the vehicle, the control unit is responsible for monitoring the operating status of each battery pack 40, controlling the allocation logic of the high-voltage power distribution unit 50, and managing the operating status of all charging guns 60. Its built-in communication module can establish a wireless connection with an external server or mobile terminal, enabling remote scheduling, battery status uploading, operation log recording, and the issuance of charging and discharging control commands, providing technical support for building an intelligent operation and maintenance management platform. The vehicle can also be equipped with optional auxiliary safety modules such as a cooling system and a fire warning system to further improve the reliability and environmental adaptability of the equipment in high-temperature or high-load scenarios.

[0063] In terms of structural design, the mobile power supply vehicle 100 adopts a highly modular structure. The vehicle body 10 integrates multiple detachable battery packs 40, multiple charging guns 60, a high-voltage power distribution unit 50, and a control unit. Each battery pack 40 can be flexibly connected in series or parallel according to usage requirements to adjust voltage and capacity; the detachable structure enables convenient replacement, enhancing endurance and maintenance efficiency.

[0064] In addition, the mobile power supply vehicle 100 is equipped with functional components such as a charger, a discharger, a charging socket, and a discharge gun. The charging socket is used to charge the on-board battery pack 40 from an external power source, while the discharge gun is used to supply power to external loads. The overall cable layout supports multiple voltage levels (110V, 220V, 380V, 450V, etc., and can reach up to 1200V or even higher through series connection of multiple battery packs), improving the vehicle's adaptability to various power consumption scenarios.

[0065] The carriage door structure is also innovative, featuring left-side, right-side, and rear-side opening structures, unlike the existing market designs that mostly have single-side or rear-side opening doors. This facilitates rapid loading, unloading, inspection, and maintenance under different environmental or space-constrained conditions, greatly improving the flexibility of use.

[0066] The carriage is also equipped with multiple external discharge cables (for direct current or alternating current) located on multiple sides of the carriage (left, right, and rear).

[0067] Overall, this invention is superior to existing technologies in terms of structural flexibility, energy supply efficiency, safety, and intelligent control. It is particularly suitable for complex application scenarios such as emergency charging of new energy vehicles and high-frequency rescue, and has good promotional value.

[0068] Furthermore, in this embodiment, the battery rack 20 has a multi-layer structure, and each layer is provided with:

[0069] A pull-out tray 32 is used to carry the battery pack 40 and facilitate its installation, removal and replacement;

[0070] A pair of guide rails 33 are provided on both sides of the tray frame 32, so that the tray frame 32 can slide in the horizontal direction to realize the pull-out function;

[0071] A locking mechanism is provided on the pallet frame 32 or the battery rack 20 to lock the pallet frame 32 after it slides in, so as to prevent the battery pack 40 from shifting or falling off during transportation.

[0072] 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.

[0073] It should be noted that the battery rack 20 structure design described in the above embodiments is designed to achieve modular management and rapid replacement of the battery pack 40, and is particularly suitable for mobile power supply needs in multiple scenarios and with high frequency of use. By setting up a pull-out tray rack 32 and a guide rail structure, each battery pack 40 can be easily removed or replaced from the vehicle compartment without the need for additional tools, greatly improving maintenance efficiency and on-site operation convenience.

[0074] The tray frame 32 is used in conjunction with the locking mechanism to automatically or manually lock the battery pack 40 after it is installed in place. This effectively prevents the battery pack 40 from becoming loose or falling off due to vehicle movement or vibration, thereby improving operational safety. It is especially suitable for rugged road conditions or long-distance driving scenarios.

[0075] Furthermore, by installing a partition between the battery rack and the bottom of the vehicle compartment, not only is the overall structural stability improved, preventing deformation of the bottom of the vehicle compartment from affecting the installation accuracy of the battery rack, but it also facilitates the separate management of the bottom of the vehicle compartment and the battery rack. The detachable connection method ensures the flexibility of the structure and the convenience of maintenance. When maintaining the battery pack 40, replacing the tray rack 32, adjusting the installation layout, or cleaning the dust accumulated at the bottom, it can be quickly disassembled and restored, improving the maintainability and adaptability of the entire vehicle system.

[0076] In summary, the structural design provided in this embodiment, while ensuring safety and reliability, also takes into account modular layout, flexible assembly, and ease of on-site operation. It is applicable to various application scenarios such as emergency power supply, temporary electric vehicle charging, power grid maintenance, and power emergency repair, and has good practical value and promotion prospects.

[0077] Furthermore, the vehicle compartment 10 also includes a power distribution control box; the power distribution control box contains contactors, relays, and / or fuses; the control unit connects to and controls the contactors or relays in the power distribution control box to switch on and off the output circuits of each charging gun 60 and the output circuit of the high-voltage power distribution unit 50. It should be noted that the power distribution control box, as a crucial intermediate link connecting the battery system and the charging gun 60, possesses electrical isolation and circuit control functions, effectively improving the overall vehicle's operational safety and system stability. By incorporating contactors, relays, and / or fuses, electrical protection and independent control of each charging circuit can be achieved, preventing damage to the battery system or charging equipment from abnormal operating conditions such as short circuits and overloads.

[0078] The control unit is connected to the contactors or relays in the power distribution control box. It manages the on / off switching of the output circuits of each charging gun 60 and the output circuit of the high-voltage power distribution unit 50 through control signals, thereby realizing intelligent scheduling and real-time intervention of the entire charging process. When abnormal parameters (such as overcurrent, overtemperature, or system failure) are detected, the control unit can quickly issue commands to cut off the relevant circuits, improving the vehicle's emergency response capability under extreme conditions.

[0079] In addition, the modular power distribution control design facilitates later maintenance and upgrades, and the control logic or protection strategy can be adjusted according to different application needs to adapt to the mobile charging service needs of multiple scenarios and standards.

[0080] Optionally, the charging gun 60 includes both a DC charging gun 60 and an AC charging gun 60. It should be noted that including both DC and AC charging guns helps improve the device's adaptability to different types of new energy vehicles. The DC charging gun 60 features high voltage and high current output characteristics, making it suitable for scenarios requiring high charging speeds. It can replenish a vehicle with a large amount of electrical energy in a short time, making it particularly suitable for emergency charging or high-frequency use scenarios in commercial vehicles. The AC charging gun 60, on the other hand, is suitable for vehicles with limited on-board charger power or those that only support AC input, meeting the basic charging needs of ordinary passenger vehicles.

[0081] Specifically, the output voltage of the charging gun 60 is adjustable, covering single-phase and three-phase low-voltage power supply systems, and is widely applicable to conventional power environments such as residential areas, underground garages, and small and medium-sized commercial venues.

[0082] The output current is adjustable to accommodate common household sockets or dedicated charging sockets. For example, a 16A current is suitable for standard single-phase household slow charging scenarios, while a 32A three-phase output is suitable for household fast charging or situations with dedicated charging station power supplies.

[0083] By combining and configuring charging guns 60 of different types, the mobile power supply vehicle 100 can flexibly switch output modes according to the charging interface type of the target vehicle and the on-site working conditions, thereby improving the breadth and practicality of the service. At the same time, in conjunction with the intelligent scheduling function of the control unit, it can also realize power distribution and working status monitoring of different types of charging guns 60, ensuring the safe and stable operation of the system when multiple guns are used simultaneously.

[0084] Furthermore, the battery pack 40 is a battery pack and is equipped with a battery management system. The battery management system monitors the voltage, current, and temperature parameters of individual battery cells and sends the monitoring data to the control unit. It should be noted that the battery pack 40 adopts a PACK battery pack structure, featuring high integration and modularity, facilitating batch assembly, replacement, and maintenance. It is suitable for operating environments with high requirements for energy density, safety, and compatibility in mobile charging scenarios. Each PACK battery pack 40 is internally equipped with a battery management system (BMS) for real-time monitoring and equalization management of individual battery cells.

[0085] The battery management system can accurately collect key operating parameters such as voltage, current, and temperature of each individual battery cell and send the monitoring data to the control unit in real time. Based on the received data, the control unit can determine the health status, remaining charge, and any abnormalities in the battery pack 40, and then dynamically adjust the charging power, control the output on / off, or promptly disconnect relevant circuits when an abnormality is detected, ensuring the safety and reliability of the vehicle operation.

[0086] Furthermore, the battery management system can implement multiple protection strategies such as overvoltage, undervoltage, overcurrent, and overtemperature protection, improving the inherent safety level of the entire vehicle and reducing safety risks caused by battery failure. This configuration enables the mobile power supply vehicle 100 to have stronger battery safety and system stability under high-intensity, long-cycle operation conditions.

[0087] Furthermore, the control unit includes a microcontroller, a display screen, and an input interface; the microcontroller is connected to the input interface to control the charging and discharging process according to the input commands, and is connected to the display screen to display the power status of each battery pack 40; the control unit is equipped with a wireless communication module to connect to an external server or mobile terminal; the microcontroller also measures the power changes during the charging and discharging process and displays them on the display screen.

[0088] It should be noted that the control unit includes a microcontroller, a display screen, and an input interface, which are used to realize intelligent control and human-machine interaction of the charging and discharging system.

[0089] The microcontroller connects to an input interface to receive control commands from the user, such as starting or stopping charging, switching operating modes, selecting batteries, and setting power. The microcontroller also connects to a display screen to show real-time information such as the battery status, operating voltage, current, power, and historical charge / discharge data for each battery pack, allowing users to intuitively understand the current system operation.

[0090] The control unit is equipped with a wireless communication module, which can connect to external servers or mobile terminals via Wi-Fi, 4G / 5G, or Bluetooth to achieve functions such as remote monitoring, data synchronization, abnormal alarm uploading, and parameter setting. Users can access system status, adjust operating parameters, or perform remote control operations through mobile applications or remote platforms.

[0091] The microcontroller also integrates power metering functionality, used to statistically analyze power changes during charging and discharging in real time, and display these changes graphically or digitally on a screen, such as cumulative charging amount, discharging duration, and average power. The system can automatically record the total power data for each charging / discharging cycle and calculate costs based on preset electricity prices or rate models, facilitating user settlement, platform billing, or commercial operations in public service scenarios.

[0092] It should be noted that this control unit, through the combination of embedded intelligent control, wireless communication, graphical interface and power metering function, can achieve precise management and efficient scheduling of the battery system, while providing clear energy consumption and cost information, which helps to promote the practical implementation and popularization of this device in various commercial application scenarios such as shared charging, mobile power rental, and emergency charging services.

[0093] In one specific embodiment, a cooling system is installed inside the vehicle compartment 10, and the cooling system is thermally connected to multiple battery packs 40. It should be noted that, through its thermal connection with the multiple battery packs 40, the cooling system effectively reduces the battery temperature during charging and discharging, preventing performance degradation or safety hazards caused by overheating. This system can employ liquid cooling or air cooling to ensure that the battery packs 40 maintain a suitable operating temperature range during high power output, thereby extending battery life and improving charging efficiency.

[0094] Furthermore, the real-time temperature regulation function of the cooling system helps prevent thermal runaway of the battery due to abnormal temperature, enhancing the overall vehicle safety. Through data linkage with the control unit, the cooling system can automatically adjust the cooling intensity according to the temperature changes of the battery pack 40, achieving intelligent temperature control management and ensuring the stable and reliable operation of the mobile power supply vehicle 100 under various operating conditions.

[0095] Furthermore, a fire early warning system is installed inside the carriage 10, which includes smoke sensors, temperature sensors, and an automatic fire extinguishing device. The smoke and temperature sensors are connected to the control unit or the fire early warning system; the automatic fire extinguishing device is triggered by the control unit or the fire early warning system to release extinguishing agent. It should be noted that the fire early warning system monitors the environment inside the carriage 10 in real time through smoke and temperature sensors, enabling early detection of fire hazards or abnormal temperature rises, effectively improving the safety protection capabilities of the mobile power supply vehicle 100. When the sensors detect that the smoke concentration or temperature exceeds a set threshold, the system quickly sends an alarm signal to the control unit or an independent fire early warning system.

[0096] Upon receiving a trigger signal, the automatic fire extinguishing device can promptly release extinguishing agent, effectively suppressing the spread of fire and reducing the risk of fire caused by battery malfunction. This linkage mechanism ensures the efficiency and reliability of emergency response, reducing personal injury and property damage. Simultaneously, the system can automatically cut off the power output of the relevant battery pack 40 to prevent further spread of electrical fires and enhance the overall safety level.

[0097] Specifically, the fire warning system issues an alarm signal and automatically cuts off the power output of the battery pack 40 when it detects an anomaly. It should be noted that when the fire warning system detects smoke or abnormal temperature, it can quickly issue an alarm signal to remind operators to take timely measures to ensure personnel safety and equipment protection. At the same time, the system automatically cuts off the power output of the battery pack 40, effectively blocking the power supply and preventing the fire from being exacerbated or secondary accidents from continuous current flow.

[0098] This automatic shut-off function is achieved through the rapid response of the control unit or fire warning system, ensuring that the faulty power supply is isolated immediately at the initial stage of an anomaly, greatly reducing safety risks, improving the protection capability and reliability of the mobile power supply vehicle 100 in emergency situations, and ensuring the safety of the vehicle and the surrounding environment.

[0099] Furthermore, the control unit is connected to smoke and temperature sensors, and also to an automatic fire extinguishing device. Responding to signals from the smoke and temperature sensors, the control unit triggers the automatic fire extinguishing device to release extinguishing agent and cuts off the power output of the battery pack 40. It should be noted that the control unit, as the core controller of the fire warning system, receives monitoring signals from the smoke and temperature sensors in real time, enabling it to accurately assess the fire risk status within the vehicle compartment 10. When the sensors detect abnormal indicators, the control unit immediately responds, automatically triggering the automatic fire extinguishing device to release extinguishing agent, rapidly suppressing the fire source and preventing its spread.

[0100] Simultaneously, the control unit executes a power management strategy, cutting off the power output of the relevant battery pack 40, thus cutting off the potential energy source for the fire and minimizing the possibility of the fire spreading. This integrated control solution achieves the linkage of fire monitoring, fire extinguishing, and power outage, significantly improving the safety protection level and emergency response capabilities of the mobile power supply vehicle 100, and ensuring the safety of equipment and personnel.

[0101] The present invention will be described in detail below with reference to a specific embodiment, but this is not intended to limit the scope of protection of the present invention.

[0102] In this embodiment, a multifunctional power supply system suitable for auxiliary power supply and charging of new energy vehicles is provided, installed inside a 7-cubic-meter van. The vehicle is converted into a mobile energy unit, with a battery rack structure inside the van body for fixing multiple battery packs 40. A window (door) is provided on one side of the vehicle for easy installation and maintenance.

[0103] In this embodiment, multiple battery packs 40 are configured inside the vehicle compartment. Each battery pack 40 has a capacity of 50 kWh and independent external discharge capability, meaning that each battery pack 40 can individually power external devices or other electric vehicles through its own power interface. The multiple battery packs 40 can be partially connected in series or parallel through a control system to achieve adjustable total discharge capacity to accommodate electrical equipment or charging loads of different power levels.

[0104] The series-connected high-voltage output can be used to drive the high-power DC charging gun 60, providing rapid energy replenishment services for other new energy vehicles; while when only a single battery pack 40 is used for output, AC power output can be provided through the AC conversion module to meet the needs of conventional household appliances or slow charging equipment.

[0105] Through the above-described configuration, the mobile energy system provided in this embodiment not only achieves efficient energy output but also supports the connection of devices with various power levels, making it suitable for a variety of application scenarios such as emergency power supply, mobile charging services, and temporary power supply at construction sites. Furthermore, the 40-module battery pack design facilitates future maintenance and capacity expansion.

[0106] In an optional embodiment, the number of charging guns 60 is adapted to the number of battery packs 40. Specifically, each battery pack 40 can be configured with an independent charging gun 60, and the two are connected and managed through a high-voltage power distribution unit 50. The high-voltage power distribution unit 50 has multiple independent output channels, each channel connecting one battery pack 40 and one charging gun 60, thereby forming a "one-to-one" or "many-to-one" power output structure.

[0107] With the above configuration, when multiple battery packs 40 work simultaneously, they can provide independent charging channels for multiple external loads or electric vehicles, improving charging efficiency and service capabilities. At the same time, the control unit can automatically control the working status of each battery pack 40 as needed, realizing functions such as load balancing, backup switching, or centralized energy output, enhancing the flexibility and safety of the power supply system.

[0108] In certain application scenarios, multiple battery packs can be connected in parallel to drive a single charging gun, depending on the actual current and voltage requirements, to achieve a "many-to-one" power supply method and meet high-power charging needs.

[0109] This implementation method is designed with full consideration of the flexible matching relationship between battery cells and charging interfaces, and can adapt to different capacity requirements and diverse application scenarios, such as charging multiple electric vehicles at the same time, or quickly replenishing a single high-power device, etc., and has high practicality and scalability.

[0110] A vehicle energy system with external discharge capability is provided and applied to a modified new energy van (7 cubic meters in volume). The vehicle is equipped with an independent battery pack 40 modules and also utilizes the vehicle's original power battery to achieve a dual-layer energy structure.

[0111] Specifically, a battery rack is installed inside the vehicle compartment, with multiple mounting positions. Each mounting position can detachably install a battery pack 40, each battery pack 40 having a capacity of 50 kWh and independent charging and discharging capabilities. In this embodiment, two battery packs 40 are configured, with a combined discharge capacity of 60–120 kWh.

[0112] Furthermore, the vehicle's own power battery system is also connected to the vehicle's energy management system and has the ability to supply power to external systems. The power battery is connected to a common DC bus or AC inverter module via an on-board bidirectional DC-DC module, enabling the vehicle's original battery to supply power to external loads or charge other vehicles / equipment while meeting its own driving and system consumption needs.

[0113] The microcontroller monitors and manages the status of the power battery, dynamically allowing or prohibiting the power battery from discharging based on preset strategies (such as remaining charge exceeding a threshold, grid demand signals, external control requests, etc.). Simultaneously, the system prioritizes the discharge of independent battery packs, only calling upon the power battery when energy replenishment is needed or under special circumstances, ensuring both driving safety and stable power supply.

[0114] The amount of electricity generated during the battery discharge process is also recorded by the metering module. Combined with the electricity price model, the cost of supplying electricity to external users is calculated, facilitating settlement management in public scenarios. Discharge data can be viewed on a display screen and synchronized to a remote terminal.

[0115] The vehicle energy system features high integration, flexible scheduling, and dual energy redundancy. In addition to meeting the vehicle's own power needs, it can also serve as a mobile power platform for emergency power supply, mobile maintenance, outdoor activities, charging services, and other scenarios.

[0116] Optionally, 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.

[0117] 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.

[0118] 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.

[0119] 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.
