Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "initial," "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.

[0051] The common problems with current mobile energy storage vehicles include: poor space utilization, resulting in a relatively reduced energy storage capacity; mobile energy storage vehicles generally only monitor the temperature inside the vehicle and cannot perform other safety monitoring, thus failing to guarantee the safe operation of the mobile energy storage vehicle; the operation inside the mobile energy storage vehicle cannot be monitored, the energy storage capacity of the energy storage device cannot be determined, and the inability to independently replace the battery cells of some energy storage devices increases maintenance time.

[0052] like Figure 1 As shown, this application embodiment provides a mobile energy storage vehicle that can be used to solve the problems encountered in the specific application environment described above. The mobile energy storage vehicle includes a carriage, and multiple energy storage devices 200 are installed in the carriage. Each energy storage device 200 includes:

[0053] The energy storage battery 202 includes multiple cells connected in series, the multiple cells are arranged in a multi-layer structure, and each cell is set independently.

[0054] The power management system 204 has its input terminals connected to the energy storage battery 202.

[0055] Voltage regulator 206, one end of which is connected to the output terminal of power management system 204, and the other end of which is used to connect to external electrical equipment.

[0056] Specifically, each cell in the energy storage battery 202 can be set up by a mounting frame. The mounting frame has a multi-layer structure, with each cell set up in each layer of the mounting frame and connected in series with each other.

[0057] Furthermore, since the individual cells in each energy storage battery 202 are connected in series and do not interfere with each other, multiple energy storage batteries 202 can be arranged closely in the vehicle compartment through mounting brackets or other means to increase the space utilization efficiency inside the vehicle compartment.

[0058] Specifically, each battery cell can be disassembled individually. If a battery cell fails, it can be removed and replaced because the cells are set up independently.

[0059] Specifically, a battery cell may include an independently powered battery or a battery pack.

[0060] The mobile energy storage vehicle provided in this application can simultaneously supply energy to multiple external devices through multiple energy storage devices installed in the vehicle compartment. In the event of a failure of some energy storage devices, the operation of other energy storage devices will not be affected. Furthermore, the energy storage battery of each energy storage device includes multiple cells connected in series and independently configured. Each cell can independently disconnect from the energy storage battery in the event of a failure, further improving reliability. Then, each energy storage device outputs to the external devices to be supplied through an independent power management system and voltage regulator. This effectively avoids the problem of complex cell connection methods in current mobile energy storage vehicles, which makes it inconvenient to replace damaged cells and reduces the response efficiency for handling emergencies.

[0061] In one exemplary embodiment, the carriage is divided into an energy storage room and an equipment room by a partition, and multiple energy storage devices are installed in the energy storage room. The energy storage devices also include:

[0062] The power conversion module has its input terminal connected to the output terminal of the power management system, and its output terminal connected to the power supply terminal of the vehicle-mounted equipment in the equipment room.

[0063] Specifically, the partition has fireproof, waterproof and heat insulation functions. In the event of a fire in the carriage, the partition can prevent the fire from spreading and prevent water from flowing to other areas, including energy storage rooms and equipment rooms, during the firefighting process, thus avoiding further expansion of the disaster.

[0064] Furthermore, the equipment room can be located closer to the front of the vehicle, while the energy storage room can be located closer to the rear of the vehicle to prevent accidents such as fires in the energy storage equipment from endangering the driver's cab.

[0065] Specifically, the power conversion module can convert electrical energy in the energy storage device into electrical energy that can be used by the vehicle equipment.

[0066] Specifically, the equipment room and the energy storage room are each equipped with independent equipment room doors and energy storage room doors.

[0067] In one exemplary embodiment, such as Figure 2 As shown, the mobile energy storage vehicle includes a main control system 300, the input terminal of which is connected to the power management system, and the power supply terminal of the main control system 300 is connected to the output terminal of the power conversion module; the on-board equipment includes:

[0069] The fire protection system 500 has its input terminal connected to the output terminal of the main control system 300, and its power supply terminal connected to the power conversion module.

[0070] Specifically, the main control system 300 is connected to the power management system to obtain the operating status of the running energy storage devices 200, so as to obtain the stored energy of each energy storage device 200 in real time, and record the stored energy of each energy storage battery after each operation. At the same time, the stored energy of each energy storage battery is displayed through the display interface of the terminal device, so that the staff can clearly see the stored energy of each energy storage device 200, so as to select the appropriate energy storage device 200 for operation, and charge each energy storage device 200 in a timely manner.

[0071] Specifically, the main control system 300 can be connected to a power conversion module, which supplies power to the main control system 300.

[0072] Furthermore, the mobile energy storage vehicle also includes an on-board power supply, located at the front of the vehicle and connected to the main control system 300. It can independently supply power to the main control system 300, preventing the main control system 300 from failing to start in the event of a battery failure. At the same time, the on-board power supply can also be connected to the vehicle's on-board host for starting the vehicle.

[0073] In one exemplary embodiment, such as Figure 2 As shown, the vehicle-mounted equipment also includes:

[0074] The temperature monitoring device 600 installed in the energy storage room is connected to the main control system 300;

[0075] The humidity monitoring device 700 installed in the energy storage room is connected to the main control system 300;

[0076] Temperature control system 400 includes:

[0077] The exhaust fan 402, located on the compartment of the equipment room of the mobile energy storage vehicle, is connected to the main control system 300.

[0079] The air conditioning system 406 includes an indoor air conditioning unit and an outdoor air conditioning unit connected to the main control system 300. The indoor air conditioning unit is located in the energy storage room, and the outdoor air conditioning unit is located on the outer wall of the carriage.

[0080] Specifically, the main control system 300 monitors the temperature of the energy storage room through the temperature monitoring device 600 installed in the energy storage room, and monitors the humidity of the energy storage room through the humidity monitoring device 700, and sends the monitoring results to the temperature control system 400, so that the temperature control system 400 can keep track of the situation of the energy storage room in real time and prevent the energy storage device 200 from catching fire, overheating or getting damp.

[0081] Specifically, the main control system 300 can also regulate the temperature of the energy storage room through the air conditioning system 406.

[0082] Furthermore, the main control system 300 can ventilate the equipment room within a preset time period, either by opening the electric louvers 404 and the exhaust fan 402 separately, or by opening the electric louvers 404 and the exhaust fan 402 in a coordinated manner.

[0083] For example, the indoor unit of the air conditioner is mounted on the partition of the energy storage room.

[0084] In one exemplary embodiment, such as Figure 2 As shown, the fire protection system 500 includes:

[0089] Specifically, the fire monitoring component 502 can monitor the specific conditions of the energy storage room and send the monitoring results to the fire control host 504. The fire control host 504 is controlled by the main control system 300. When a fire is detected, it controls the sound and light alarm 506 to sound to alert the staff, and at the same time automatically extinguishes the fire through the fire extinguishing device 508 to achieve the purpose of extinguishing the initial fire.

[0090] In one exemplary embodiment, the fire monitoring component includes:

[0091] At least one of a smoke detector, a temperature detector, and a combustible gas detector.

[0092] In one exemplary embodiment, the fire protection system further includes:

[0093] Fire hydrants are installed in the equipment room;

[0094] A fire pump has an inlet that connects to the outlet of a municipal water supply pipe via a fire hose, and an outlet that connects to external water-using equipment via a fire hose.

[0095] Specifically, in the event of a fire outside or inside a vehicle, the fire hose on the mobile energy storage vehicle can be connected to a nearby water source, and the water can be pumped to the fire area to temporarily extinguish the fire and prevent it from spreading further.

[0096] In one exemplary embodiment, the vehicle-mounted device includes:

[0097] Cable winches, located in the equipment room;

[0098] The cable is wound on a cable reel, with one end connected to the other end of the voltage regulator and the other end connected to external electrical equipment.

[0099] In one exemplary embodiment, the vehicle-mounted device includes:

[0100] Cable winches, located in the equipment room;

[0101] The cable is wound on a cable reel, with one end connected to the other end of the voltage regulator and the other end connected to external electrical equipment.

[0102] Specifically, during the charging process of the mobile energy storage vehicle provided in this application, external electrical equipment can be connected to the voltage regulator via a cable.

[0103] Furthermore, to facilitate the collection of wire harnesses, the cables can be wound up and placed in the equipment room using a cable winch without the need for cables.

[0104] This application also provides a mobile energy storage system, including the mobile energy storage vehicle as described above, and further comprising:

[0105] A remote server, wherein the output of the remote server is communicatively connected to the input of the main control system;

[0106] A terminal device, wherein the input terminal of the terminal device is connected to the output terminal of the main control system.

[0107] Specifically, the main control system can be connected to terminal devices, enabling staff to control the main control system through the terminal devices, and in turn, control the temperature control system and the fire protection system through the main control system.

[0108] Furthermore, both the fire pump and the cable winch are electrically controlled, allowing operators to control the opening and closing of the fire pump and the winding and unwinding of the cable via terminal equipment.

[0109] Furthermore, the terminal device also includes a display module, which can be used to display the power status of the energy storage battery connected to the power management system, the temperature information monitored by the temperature monitoring device, the humidity information monitored by the humidity monitoring device, and the fire information monitored by the fire monitoring component.

[0110] In one exemplary embodiment, both the energy storage room and the equipment room are equipped with lighting.

[0111] The lighting in the energy storage room is linked to the door of the energy storage room, and the lighting turns on when the door of the energy storage room is opened; the lighting in the equipment room is also linked to the door of the equipment room, and the lighting turns on when the door of the equipment room is opened.

[0112] Specifically, sensors can be installed on the doors of both the energy storage compartment and the equipment compartment. The output of the sensors is connected to the control terminal of the lighting, which is used to obtain the opening information of the compartment doors when they are open and control the lighting to turn on.

[0113] To further illustrate the solution of this application, a complete example is provided below. This application also provides a specific embodiment: the multi-functional mobile energy storage vehicle provided by this application includes a front end and a body; wherein: the front end is equipped with a driver's cab, and the body includes a vehicle chassis, wheels, and a cargo box; the cargo box and the vehicle chassis can be an integrated design or separate designs. Specifically, when the cargo box and the main body of the vehicle are designed as an integrated unit, such as... Figure 3 As shown, all wheels are mounted on the vehicle chassis of the main body, and the cargo box 800 is fixed to the vehicle chassis; when the cargo box 800 and the main body 900 are designed separately, as... Figure 4 As shown, the mobile energy storage vehicle is a semi-trailer, meaning that part of the cargo box 800 is attached to the vehicle chassis. At this time, some wheels are set on the vehicle chassis, and the remaining wheels are set at the bottom of the cargo box 800. The front of the vehicle is fixedly connected to one end of the vehicle chassis for towing the vehicle body, so as to realize the movement of the multi-functional mobile energy storage vehicle. The front of the vehicle is equipped with a driver's cab for the use of staff.

[0114] Furthermore, the vehicle compartment includes an energy storage room and an equipment room; the equipment room houses various control devices for the multi-functional mobile energy storage vehicle. Specifically, the energy storage room and equipment room are arranged sequentially from the rear to the front of the vehicle, with the energy storage room near the rear and the equipment room near the front, ensuring the energy storage devices are located far from the driver's cab for driver safety. Additionally, to ensure the safety of all areas of the mobile energy storage vehicle, a partition is installed between the energy storage room and the equipment room. This partition has fireproof, waterproof, and heat insulation functions to prevent fire and water from entering and damaging the equipment in the event of a fire in the energy storage room, equipment room, or other areas outside the vehicle compartment. Furthermore, multiple doors are located on both sides of the vehicle compartment, including doors for the energy storage room and equipment room; these doors can be opened independently without affecting each other. Having different doors for each space allows for more flexible operation by staff; simultaneously, the doors on both sides of the vehicle compartment facilitate use.

[0115] Specifically, the energy storage room contains an energy storage device, including multiple energy storage batteries, a battery management system, and a voltage regulator. The energy storage room also contains multiple mounting racks arranged sequentially. Each mounting rack has multiple layers, with one battery cell installed on each layer. The multiple cells on each rack form an energy storage battery for supplying power. Here, a battery cell refers to an independently powered battery or battery pack. Specifically, the multiple cells in the energy storage battery are connected in series. When a cell malfunctions, it can be directly removed from the corresponding position on the mounting rack and replaced with a new cell, facilitating replacement and maintenance. In practical implementation, any energy storage battery can be selected to supply power according to usage needs, making it more flexible and convenient than the energy storage batteries in existing energy storage devices. The battery management system is electrically connected to each energy storage battery, converting the power from each battery and outputting it to the outside through the voltage regulator. For example, for ease of use, the connection between the battery management system and the energy storage battery is pluggable. For example, there can be one or more battery management systems. Since the energy storage battery in this invention has multiple batteries, it can simultaneously supply power to multiple external loads. The energy storage device also includes a power conversion module, which is electrically connected to the power management system, for obtaining the power converted by the battery management system and converting it into the operating power of the device for use by the equipment in the mobile energy storage vehicle, such as the various devices between devices.

[0116] The mobile energy storage vehicle provided in this embodiment also includes a temperature control system and a fire suppression system. Both the temperature control system and the fire suppression system are electrically connected to the power conversion module to obtain electrical energy from it. The temperature control system includes an air conditioning system, comprising an indoor unit and an outdoor unit, with the outdoor unit mounted on the roof of the vehicle. The indoor unit is installed in the energy storage compartment, on the partition between the energy storage compartment and the equipment room, and the main control system in the equipment room controls and shuts down the air conditioning system. The energy storage compartment is equipped with a temperature monitoring device and a humidity monitoring device, both electrically connected to the temperature control system. The temperature control system controls the start and stop of the air conditioning system based on the monitored temperature and humidity, thereby maintaining the operating temperature and humidity of the energy storage batteries within a suitable range to ensure stable battery operation. On the other hand, the temperature control system also includes exhaust fans and louvers. The exhaust fans are installed on the equipment compartment to ventilate, exhaust, and dissipate heat. The louvers are installed on the roof of the equipment compartment, and ventilation is achieved by linking the exhaust fans and louvers. For example, under normal operating conditions, ventilation is achieved through the louvers; when ventilation through the louvers is insufficient, the exhaust fans can be activated. Similarly, during the rainy season, to prevent water from entering the equipment compartment, the louvers can be closed and the exhaust fans activated. Likewise, temperature and humidity monitoring devices can be installed in the equipment compartment to monitor the temperature and humidity, thereby controlling the operation of the exhaust fans and louvers. Both the equipment compartment and the energy storage compartment are equipped with lighting; these lights can be linked to the compartment doors, turning on when the doors are open and turning off when the doors are closed. Additionally, depending on the specific circumstances, louvers can also be installed on the energy storage compartment, such as on the rear of the compartment, for ventilation and heat dissipation.

[0117] Specifically, the fire protection system includes audible and visual alarms, smoke detectors, temperature detectors, combustible gas detectors, and a fire control host. The fire control host is electrically connected to a power conversion module to obtain power. Simultaneously, the fire control host is electrically connected to the audible and visual alarms, smoke detectors, temperature detectors, and combustible gas detectors to acquire smoke data, temperature data, and combustible gas data, etc., to implement alarm functions based on the monitored data. For example, if the above data exceeds a preset value, the fire control host controls the audible and visual alarms to issue an alarm signal. In actual use, multiple audible and visual alarms can be set to display different alarm signals; or different alarm signals can be distinguished by the display color or frequency of the audible and visual alarms. In addition, temperature detectors can be integrated with the aforementioned temperature monitoring devices, and the specific configuration can be determined according to actual needs. The fire protection system also includes fire extinguishers; the fire control host controls the automatic opening of the fire extinguishers to achieve automatic fire extinguishing, preventing losses in cases where personnel cannot handle the fire in time by controlling the fire with equipment. The fire extinguishers are dry powder fire extinguishers. Furthermore, the fire protection system in this utility model also includes a fire pump and fire water pipes. When an external fire breaks out, the fire hose on the mobile energy storage vehicle can be connected to a nearby water source, and a fire pump can deliver water to the fire area to temporarily extinguish the fire and prevent it from spreading further. This utility model provides temporary firefighting services by installing a temporary fire pump and fire hose on a mobile energy storage vehicle.

[0118] Furthermore, the equipment room is equipped with a cable winch for cable winding and unwinding. In use, one end of the cable winch is electrically connected to the energy storage device in the energy storage room, and the other end is electrically connected to an external load to supply power. The cable winch includes a base and a spool mounted on the base, with the cable wound on the spool. A rocker arm is also provided on the spool; by moving the rocker arm, the spool rotates on the base to unwind the cable. The driver's cab also houses a main control system and terminal equipment. The main control system is electrically connected to the terminal for human-machine interaction with the operator. The main control system also includes a main control chip and a communication module. The main control chip communicates with a remote backend server via the communication module, enabling communication such as receiving instructions from the remote backend server or uploading data collected by itself. The main control chip is also electrically connected to the temperature control system and the fire protection system to obtain their operating status. The main control chip is also electrically connected to the power management system to acquire the operating status of the running energy storage devices, including the stored energy of each device. It also records the stored energy of each battery after each operation and displays this data on the terminal device's interface for staff to review, enabling them to select the appropriate energy storage device and recharge it promptly. A vehicle power supply is located at the bottom of the mobile energy storage vehicle's front, electrically connected to the main control chip to provide power and drive the vehicle. This invention avoids the problem of the main control chip failing to function when the energy storage battery malfunctions by providing a separate power supply for both vehicle operation and the main control chip. Furthermore, the main control chip receives task instructions from a remote server via a communication module and displays them to staff through the terminal device in the driver's cab. Staff can receive these instructions and perform corresponding operations, such as driving the mobile energy storage vehicle to the designated task location within a specified time. The task instructions include the task location, time, operation details, and other information. Upon receiving the instructions, personnel move the mobile energy storage vehicle to the designated location. Upon completion of a task, the system promptly reports the completion status to a remote server via the main control chip. An emergency stop button, electrically connected to the main control chip, controls the entire mobile energy storage vehicle's operation. In case of an emergency, the button stops the vehicle, ensuring safety. A handheld terminal is also located in the driver's cab, communicating with the terminal equipment there for synchronized operation. While personnel are working, they can directly control the terminal equipment in the cab via the handheld terminal.

[0119] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
