Description

Technical Field

[0001] This invention belongs to the field of charging cabin technology, specifically a mobile energy storage and charging integrated cabin. Background Technology

[0002] Mobile energy storage modules, as flexible energy solutions, play a crucial role in scenarios such as power emergency response and peak shaving at new energy power plants. With the increasing penetration rate of new energy vehicles and the accelerated electrification of logistics transportation, flatbed trucks (platform height ≤ 1.2m, without suspension and shock absorption systems) have become the mainstream carrier for transporting heavy-duty electric equipment. However, current mobile charging equipment suitable for this type of vehicle still faces significant technical bottlenecks: On the one hand, functional modules are fragmented. Mainstream mobile energy storage vehicles are typically only equipped with an AC380V industrial output interface, which cannot directly provide fast charging services for electric engineering vehicles. If an external charging pile is connected, the cabling needs to be modified and an independent control cabinet needs to be installed, with deployment time exceeding 3 hours, severely weakening the equipment's mobility and emergency response capabilities. On the other hand, single charging pile equipment lacks a built-in energy storage unit and must rely on an external power source, making it difficult to apply in the field or in off-grid scenarios.

[0003] On the other hand, there is insufficient adaptability to different carriers. Existing mobile energy storage compartments (including models with integrated charging modules) generally rely on the original shock absorption structure of the truck chassis (such as leaf spring suspension and balance beam devices) for vibration buffering. Once deployed on a flatbed transport vehicle without a suspension system, the compartment cannot effectively dissipate vibration energy, and is prone to equipment damage or performance degradation due to impact vibration.

[0004] In summary, existing mobile charging technologies are insufficient to achieve fast, stable, and integrated external charging functionality on flatbed transport vehicle platforms. There is an urgent need for a new type of energy storage charging cabin solution that is highly integrated, shock-resistant, adaptable, and quick to switch. Summary of the Invention

[0005] To address the issues that current energy storage modules cannot directly charge external vehicles and that the risk of internal equipment damage due to vibration during transport is high, this invention provides a mobile integrated energy storage and charging module.

[0006] This invention is achieved through the following technical solution: A mobile energy storage and charging integrated cabin includes an energy storage cabin, which is sequentially divided into a cable compartment, a combiner control compartment, a battery compartment, a PCS compartment, and a charging pile compartment. The battery compartment is equipped with a battery module and is located in the middle of the energy storage cabin. The cable chamber is equipped with a cable reel and an external AC power socket, and the combiner control chamber is equipped with a control combiner cabinet. The cable reel and the external AC power socket are connected to the battery module through the control combiner cabinet. The PCS compartment is equipped with an on-board energy storage converter, and the charging pile compartment is equipped with a charging pile body and a quick-lock charging gun access port. The charging pile body is connected to the battery module through the on-board energy storage converter, and the quick-lock charging gun access port is embedded in the side wall of the energy storage compartment.

[0007] The energy storage compartment integrates external cables, energy storage batteries, power conversion system (PCS), and charging pile body, realizing the integrated configuration of energy storage power supply and fast charging, thereby solving the problem of discrete functional modules. Considering the vibration of internal equipment, the heavier battery module is adjusted to the middle of the compartment, forming a configuration with charging and discharging on both sides, optimizing the weight structure layout and reducing the vibration amplitude during movement.

[0008] A further improvement of the present invention is that an explosion-proof exhaust fan and an explosion-proof fan inlet are provided on opposite side walls of the battery compartment, and an explosion vent is provided above the explosion-proof fan inlet. The explosion-proof exhaust fan and the explosion-proof fan inlet increase air circulation within the battery compartment, which helps to reduce the operating temperature within the battery compartment; the explosion vent further enhances the safety level of the battery compartment, effectively preventing pressure buildup within the compartment from causing greater risks.

[0009] A further improvement of the present invention is that the battery compartment is also equipped with a high-voltage box, which is connected in series between the output terminal of the battery module and the input terminal of the vehicle-mounted energy storage converter. During charging, the high-voltage box performs graded constant current charging to the battery module after matching the voltage and power; during discharging, the battery module supplies power to external devices through the high-voltage box, forming a bidirectional reversible energy transmission channel.

[0010] A further improvement of this invention is that a grounding steel rod is connected to the cable reel. This expands the application scenarios, provides effective grounding protection, prevents accidents such as leakage and lightning strikes, and significantly enhances operational safety.

[0011] A further improvement of the present invention is that the aforementioned AC power external connector is embedded in the side wall of the energy storage compartment. This optimizes the structural layout and facilitates quick connection of external power input and output.

[0012] A further improvement of the present invention is that the aforementioned combiner control room is also equipped with a control room manual control panel, which is electrically connected to the control combiner cabinet and is embedded in the side wall of the energy storage compartment. A display screen for controlling and monitoring the overall operating status of the compartment is located on the compartment door for easy operation, greatly improving the convenience of equipment operation and maintenance efficiency.

[0013] A further improvement of the present invention is that the charging pile chamber is also equipped with a cooling fan, which is embedded in the side wall of the energy storage compartment. This helps to quickly dissipate the large amount of heat generated during the operation of the charging pile, preventing the charging pile from derating or shutting down due to overheating, ensuring the continuous and stable output of the high-power DC fast charging function, and improving charging efficiency and equipment reliability.

[0014] A further improvement of this invention is that each outer wall surface of the battery module is connected to the inner wall of the battery compartment via a wire rope shock absorber, and each outer wall surface of the on-board energy storage converter is connected to the inner wall of the PCS compartment via a wire rope shock absorber. This forms six-sided limiting and helps absorb transportation vibration energy. The wire rope shock absorbers can effectively isolate and dissipate the severe vibration and impact energy generated by the flatbed transport vehicle during driving and operation, compensating for the shortcomings of the flatbed vehicle without a chassis suspension system.

[0015] A further improvement of the present invention is that the upper part of the aforementioned PCS compartment is partitioned into a liquid cooling unit compartment, which is equipped with an on-board liquid cooling unit. The on-board liquid cooling unit is circulated with liquid cooling pipes that extend to the battery compartment. The liquid cooling pipes effectively cool the battery compartment, which generates significant heat during charging and discharging, thereby improving energy efficiency and extending battery life.

[0016] A further improvement of this invention is that the aforementioned PCS compartment is also equipped with an AC / DC module, which is connected in series between the output terminal of the battery module and the input terminal of the vehicle-mounted liquid cooling unit. The AC / DC module is used to realize AC / DC conversion to meet the operating requirements of the vehicle-mounted liquid cooling unit in the liquid cooling unit compartment, providing a stable and reliable power supply for the liquid cooling unit without the need for an external power supply. This ensures that the thermal management system can operate independently and normally in any operating mode, further enhancing the integration of the entire compartment and its adaptability to field operations.

[0017] As can be seen from the above technical solutions, the beneficial effects of the present invention are: the energy storage compartment integrates external cables, energy storage batteries, power conversion (PCS) and charging pile body, realizing the integrated configuration of energy storage power supply and fast charging, thereby solving the problem of functional module discreteness; considering the problem of internal equipment vibration, the heavier battery module is adjusted to the middle of the compartment, forming a configuration of charging and discharging on both sides, optimizing the weight structure layout and reducing the vibration amplitude during movement.

[0026] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figures 1-6 As shown, the present invention discloses a mobile energy storage and charging integrated cabin, including an energy storage cabin, which is sequentially divided into a cable compartment 1, a current control compartment 2, a battery compartment 3, a PCS compartment 11 and a charging pile compartment 7. The battery compartment 3 is equipped with a battery module 26 and is located in the middle of the energy storage cabin. The cable compartment 1 is equipped with a cable reel 24 and an external AC power socket 17 suitable for 380V. The combiner control compartment 2 is equipped with a control combiner cabinet 25. The cable reel 24 and the external AC power socket 17 are connected to the battery module 26 through the control combiner cabinet 25. The PCS compartment 11 is equipped with an on-board energy storage converter 29, and the charging pile compartment 7 is equipped with a charging pile body 28 and a quick-lock charging gun access port 22. The charging pile body 28 is connected to the battery module 26 through the on-board energy storage converter 29, and the quick-lock charging gun access port 22 is embedded in the side wall of the energy storage compartment.

[0028] The PCS chamber 11 is equipped with an exhaust fan 21 on its side wall and an air inlet louver 12 on its opposite side wall. The exhaust fan 21 can dissipate the heat inside to the outside.

[0029] The energy storage compartment integrates external cables, energy storage batteries, power conversion (PCS) and charging pile body 28, realizing the integrated configuration of energy storage power supply and fast charging, thereby solving the problem of discrete functional modules. Considering the vibration of internal equipment, the heavier battery module 26 is adjusted to the middle of the compartment, forming a configuration with charging and discharging on both sides, optimizing the weight structure layout and reducing the vibration amplitude during movement.

[0030] The bottom of the energy storage compartment is equipped with container corner fasteners 9, which are locked to the corner fasteners of the semi-trailer platform via the bottom lock of the flatbed truck, forming a rigid shear-resistant connection. The bottom of the energy storage compartment is also equipped with container lifting columns 10 to facilitate the lifting and transfer operations of the energy storage compartment.

[0031] The battery compartment 3 is equipped with an explosion-proof exhaust fan 19 and an explosion-proof fan inlet 13 on opposite side walls. An explosion vent 4 is also provided above the explosion-proof fan inlet 13. The explosion-proof exhaust fan 19 and the explosion-proof fan inlet 13 increase air circulation in the battery compartment 3, which helps to reduce the operating temperature inside the battery compartment 3. The explosion vent 4 further enhances the safety level of the battery compartment and effectively prevents the accumulation of pressure inside the compartment from causing greater risks.

[0032] The side wall of the battery compartment 3 is equipped with 18 dustproof louvers, which can achieve heat dissipation while reducing the entry of dust.

[0033] The battery compartment 3 is also equipped with a high-voltage box 32, which is connected in series between the output terminal of the battery module 26 and the input terminal of the vehicle-mounted energy storage converter 29. During charging, the high-voltage box 32 performs graded constant current charging to the battery module 26 after matching the voltage and power. During discharging, the battery module 26 outputs power to external equipment through the high-voltage box 32, forming a bidirectional reversible energy transmission channel.

[0034] A grounding steel probe 23 is connected to the cable reel 24. This expands the usage scenarios, forms good grounding protection, prevents accidents such as electric leakage and lightning strikes, and improves the working safety level.

[0035] The AC external socket 17 is embedded in the side wall of the energy storage cabin. This optimizes the structural layout and facilitates the quick plugging of external power input and power output.

[0036] A control room manual operation screen 15 is also provided in the busbar control room 2. The control room manual operation screen 15 is electrically connected to the control busbar cabinet 25 and is embedded in the side wall of the energy storage cabin. It is a display screen for controlling and detecting the working state of the whole cabin, arranged on the cabin door for easy operation, greatly improving the convenience of equipment operation and the operation and maintenance efficiency.

[0037] A fire extinguisher cylinder is also provided in the busbar control room 2. The fire extinguisher cylinder is connected to the bottom of each chamber through a pipeline, and temperature and gas detectors are installed on the fire pipelines at the top of each chamber. When triggered, the perfluoroketone fire extinguishing agent in the fire extinguisher cylinder is automatically released. A fire water injection port 16 is also provided at the bottom of the energy storage cabin, which is connected to the fire pipeline; when a fire breaks out, external water sources can be connected to reach the target chamber through the fire pipeline. A fire control panel 20 capable of联动消防气瓶 (it seems there is a mistake here, maybe "linking the fire extinguisher cylinder") is also provided on the side wall of the busbar control room 2.

[0038] A cooling fan 8 is also provided in the charging pile room 7, and the cooling fan 8 is embedded in the side wall of the energy storage cabin. This helps to quickly discharge a large amount of heat generated during the operation of the charging pile to the outside, preventing the charging pile from derating or shutting down due to overheating, ensuring the continuous and stable output of the high-power DC fast charging function, and improving the charging efficiency and equipment reliability.

[0039] The outer wall surfaces of each battery module 26 are respectively connected to the inner wall of the battery chamber 3 through wire rope shock absorbers 31, and the outer wall surfaces of each vehicle-mounted energy storage inverter 29 are respectively connected to the inner wall of the PCS chamber 11 through wire rope shock absorbers 31. This helps to absorb the vibration energy during transportation. The wire rope shock absorber 31 can effectively isolate and dissipate the剧烈振动与冲击能量 (it seems there is a mistake here, maybe "severe vibration and impact energy") generated by the flatbed transporter during driving and operation, compensating for the defect of the flatbed truck without a chassis suspension system.

[0040] A liquid cooling unit room 5 is partitioned in the upper part of the PCS chamber 11. A vehicle-mounted liquid cooling unit 6 is provided in the liquid cooling unit room 5. The vehicle-mounted liquid cooling unit 6 is connected in a cycle through a liquid cooling pipeline 27, and the liquid cooling pipeline 27 extends to the battery chamber 3. The battery chamber 3 that generates a large amount of heat during charge and discharge is cooled in time through the liquid cooling pipeline 27, improving the energy efficiency and extending the battery life.

[0041] The PCS compartment 11 is also equipped with an AC / DC module 30, which is connected in series between the output terminal of the battery module 26 and the input terminal of the vehicle-mounted liquid cooling unit 6. The AC / DC module 30 is used to realize AC / DC conversion to meet the operation of the vehicle-mounted liquid cooling unit 6 in the liquid cooling unit compartment 5, providing a stable and reliable power supply for the liquid cooling unit without the need for an external power supply. This ensures that the thermal management system can operate independently and normally in any working mode, further enhancing the integration of the entire compartment and its adaptability to field operations.

[0042] All the aforementioned compartments equipped with heat dissipation windows have ventilation openings on their opposite side walls to prevent excessive negative pressure from forming during heat dissipation operations. Adjacent compartments are separated by fireproof partitions with pre-installed heat dissipation channels. Each compartment is also equipped with drainage holes 14 to drain water caused by rain, snow, or condensation.

[0043] In summary, the working principle of this device is as follows: This energy storage compartment adopts multi-system collaborative control to achieve efficient operation: During charging and discharging, external electrical energy is transmitted to the high-voltage box 32 via the waterproof cable reel 24. The battery module 26 is managed for charging and discharging through the cluster control module, and the AC / DC conversion is completed by the on-board energy storage converter 29. Thermal management is based on liquid cooling. After the on-board liquid cooling unit 6 drives the coolant to absorb the heat from the battery, it circulates through the liquid cooling pipeline 27 and returns to the on-board liquid cooling unit 6 for centralized heat dissipation. At the same time, the intake fan of the PCS compartment 11 actively exhausts air to assist in cooling, forming a dynamic temperature control mechanism. The safety protection module responds in stages based on sensor data. In case of abnormality, it cuts off the power supply, locates the hidden danger, and initiates segmented fire suppression. The fire extinguishing gas cylinders are linked to cover the fire source. The compartment ensures transportation stability and space utilization through the symmetrical layout of the battery rack and the stacked structure design.

[0044] The energy storage compartment is adapted to the size of the flatbed trailer on which it is supported, which helps to optimize the structural layout of the energy storage compartment, ensure the stable assembly of the energy storage compartment on the flatbed trailer, and facilitate the space planning of each compartment inside the energy storage compartment.

[0045] The flatbed trailer measures 7600mm x 2550mm, with an energy storage compartment height of 2300mm. Combined with a 1.2m chassis, the overall vehicle height is 3.5m, meeting road height restrictions. Alternatively, a 1.5m chassis can be used to accommodate other height-restricted scenarios while improving maneuverability.

[0046] In summary, the working process of this device is as follows: Charging and discharging path: During the charging phase, external power is first connected to the system via cable reel 24. After voltage matching and power distribution by high-voltage box 32, it performs graded constant current charging to matrix battery module 26. During the discharging phase, battery module 26 collects and outputs electrical energy via high-voltage box 32. The DC-to-AC power conversion is completed by on-board energy storage converter 29, and finally, power is supplied to external equipment via cable reel 24, forming a bidirectional reversible energy transmission channel. The charging pile in charging pile room 7 draws power from the matrix battery pack and charges the electric vehicle via on-board energy storage converter 29.

[0047] Thermal management path: The vehicle-mounted liquid cooling unit 6 deployed inside the liquid cooling unit compartment 5 drives the cooling medium to circulate in the closed liquid cooling pipeline 27, directionally absorbing the Joule heat and reaction heat generated during the battery charging and discharging process, and then pumping the heat-carrying medium back to the vehicle-mounted liquid cooling unit 6 for forced convection cooling; simultaneously, the axial flow intake fan configured in the PCS compartment 11 starts the gradient exhaust strategy according to the inverter temperature rise state, and quickly exhausts the heat generated by the power electronic devices outside the compartment through negative pressure diversion, forming a composite heat exchange mechanism of liquid cooling main control and air cooling synergy.

[0048] This system employs a three-tiered fire response mechanism: Level 1 warning (increasing sampling frequency and recording data when VOC detection is abnormal); Level 2 warning (triggering audible and visual alarms, activating the exhaust system, cutting off power to the cabin and limiting PCS power when CO, smoke, or temperature exceed limits, and simultaneously locating the potentially hazardous battery module 26 and sending an alarm); Level 3 alarm (closing exhaust ventilation in the event of thermal runaway fire, locating the target battery cluster according to the detector, initiating three directional extinguishing agent releases, and coordinating fire suppression across the entire cabin). Through tiered threshold judgment and targeted responses, the system balances the accuracy of early warning with the ability to rapidly suppress extreme fires.

[0049] The present invention discloses a mobile energy storage and charging integrated cabin, which integrates external cables, energy storage batteries, power conversion system (PCS) and charging pile body, realizing the integrated configuration of energy storage power supply and fast charging, thereby solving the problem of discrete functional modules; considering the problem of internal equipment vibration, the heavier battery module is adjusted to the middle of the cabin, forming a configuration of charging and discharging on both sides, optimizing the weight structure layout and reducing the vibration amplitude during movement.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
