The installation process is complex and cumbersome, and the systems cannot be moved flexibly after installation, resulting in limited applicability.

[0004] Therefore, a new type of mobile energy storage and charging system is urgently needed to solve the above problems.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0006] The main purpose of this application is to provide a new type of mobile storage and charging system to solve the problem that most existing storage and charging systems are fixed and cannot be moved flexibly, which limits their applicability.

[0007] To achieve the above objectives, this application provides a novel mobile energy storage and charging system, comprising a frame, in which a battery system, a converter, a charging module, a liquid-cooled charging gun, a main control unit, and a power distribution panel are disposed.

[0025] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 In one embodiment, a novel mobile energy storage and charging system includes a frame 1. The frame 1 houses a battery system 4, a converter 5, a charging module 2, a liquid-cooled charging gun, a main control unit 7, and a power distribution panel 6. The output of the power distribution panel 6 is connected to the input of the main control unit. The output of the main control unit 7 is connected to the battery system 4, the converter 5, the charging module 2, and the liquid-cooled charging gun. The output of the battery system 4 is connected to the converter 5, and the output of the charging module 2 is electrically connected to the liquid-cooled charging gun. The battery system 4, the converter 5, and the liquid-cooled charging gun are cooled by a liquid-cooling system 3 located inside the frame 1. The converter 5 is specifically a DC-DC auxiliary power source.

[0026] Furthermore, data acquisition units are respectively provided in the charging module 2 and the battery system 4. After receiving the collected charging operation data and battery management system data, the main control unit 7 performs data processing and analysis to achieve the effect of real-time detection during the charging process.

[0027] A mechanical sensor is installed at the connection between the liquid-cooled charging gun and the vehicle charging interface. For example, a micro switch is used. When the charging gun is correctly inserted into the vehicle charging interface, the micro switch is triggered, indicating that the connection is normal. If the charging gun is pulled out or not fully inserted, the state of the micro switch changes. After receiving the signal, the main control unit 7 determines that the connection is abnormal and determines the connection status by detecting the electrical signals in the charging cable.

[0028] When the main control unit 7 detects an abnormal charging cable connection or a device malfunction alarm, it sends a stop charging command to the charging module 2. Upon receiving the command, the charging module 2 stops outputting charging current and voltage. Simultaneously, the main control unit 7 can cut off the power supply to the charging circuit via the distribution panel 6, ensuring that no current flows through the charging cable in a fault condition, thereby protecting personal and vehicle safety.

[0029] It is understood that the novel mobile storage and charging system provided in this application, by setting up components such as battery system 4, converter 5, charging module 2, liquid-cooled charging gun, main control unit 7, power distribution board 6, and liquid cooling system 3 in the frame 1, can meet the power supply requirements, can be flexibly moved according to actual charging needs, and has a relatively wide range of applications. There is no need to lay power lines when placing it, making it simpler and more convenient overall. At the same time, during use, the liquid cooling system 3 can be used to cool the battery system 4, converter 5, and liquid-cooled charging gun, preventing the storage system from overheating and causing abnormalities.

[0030] Specifically, please refer to Figure 1 Based on the above embodiments, it also includes a DC input protection unit and a DC output protection unit. A DC input protection unit is provided between the distribution panel 6 and the DC power supply, and a DC output protection unit is provided between the output end of the distribution panel 6 and the main control unit 7.

[0031] It is understandable that, to ensure the safety of charging and discharging, corresponding protection measures are set on the distribution panel 6. The DC input protection unit specifically includes a DC input overvoltage protection unit and a DC input undervoltage protection unit. Specifically, the DC input overvoltage protection unit can detect excessively high voltage and take timely measures, such as cutting off the input circuit or adjusting the voltage to a safe range through a step-down circuit, thereby protecting the components in the distribution panel 6 from the impact of excessively high voltage. The DC input undervoltage protection unit can detect such undervoltage conditions and prevent the distribution panel 6 from continuing to operate under insufficient voltage, avoiding possible malfunctions and damage. Furthermore, the DC output protection unit specifically includes a DC output overvoltage protection unit and a DC output short-circuit protection unit. Specifically, the DC output overvoltage protection unit can monitor the output voltage. Once it detects that the voltage is too high, it will take protective measures, such as limiting the voltage output or cutting off the output circuit, to protect the safety of the main control unit 7. The DC output short-circuit protection unit can quickly detect short-circuit conditions and immediately cut off the output circuit to prevent excessive current from damaging the distribution panel 6 and the main control unit 7, protecting the safety of the entire circuit system.

[0032] Specifically, based on the above embodiments, the liquid cooling system 3 includes a water pump, a water tank, a radiator, a temperature sensor, and a liquid cooling pipe. The input end of the water pump is connected to the water tank, the input end of the water tank is connected to the radiator, the output end of the water pump is connected to the liquid cooling pipe, and a temperature sensor is installed on the liquid cooling pipe.

[0033] It is understandable that the surface of the liquid cooling pipe is in contact with the surface of the battery system 4, the surface of the converter 5, and the surface of the liquid-cooled charging gun, and the heat dissipated by the above components during operation is carried away by heat transfer. For example, the temperature sensor monitors the temperature of the liquid-cooled charging gun. When the temperature of the charging gun is too high, the liquid cooling system 3 will take measures, such as increasing the flow rate of coolant or improving the heat dissipation efficiency of the radiator, to ensure that the temperature of the charging gun is within a safe range.

[0034] Specifically, please refer to Figure 2 Based on the above embodiments, it also includes a T-connector, and the output end of the liquid cooling system 3 is connected to the liquid cooling charging gun, the battery system 4, and the converter 5 through the T-connector.

[0035] It is understandable that the above settings enable the liquid-cooled charging gun, battery system 4, and converter 5 to share a single liquid-cooling system 3, thus saving costs while ensuring the effectiveness of liquid cooling.

[0036] Specifically, based on the above embodiments, a solenoid valve is also included, and a solenoid valve is connected between the liquid-cooled charging gun and the liquid-cooling system 3.

[0037] It is understandable that a solenoid valve is installed on the liquid cooling pipe that provides liquid cooling for the liquid-cooled charging gun. When the charging gun is not in operation, the solenoid valve is closed to prevent the internal liquid cooling pipe from getting too cold and causing condensation on the outer sheath of the charging gun.

[0038] Specifically, based on the above embodiments, the frame 1 is composed of several nine-fold steel sections, and multiple mounting holes are provided on the several nine-fold steel sections.

[0039] It is understandable that frame 1 uses nine-fold steel, which is simple and convenient to install. The densely packed mounting holes provide convenient and flexible interfaces for the shell and other mounting components. At the same time, the closed section also ensures the strength of the main frame 1 and the overall appearance.

[0040] Specifically, based on the above embodiments, an insulating layer is also included, which wraps around the liquid-cooled charging gun.

[0041] It is understandable that setting an insulating layer can achieve an insulating effect and prevent leakage and other situations from occurring.

[0042] In summary, the mobile energy storage and charging system provided in this application adopts a modular design, consisting of a battery system 4, a converter 5, a charging module 2, a liquid-cooled charging gun, a main control unit 7, a distribution panel 6, and a main frame 1. The energy storage and charging system has multiple protection functions. During charging, it can monitor charging operation data, battery management system data, charging cable connection status, and equipment fault alarm status in real time. It automatically stops charging when there is a connection abnormality or fault alarm, ensuring personal and vehicle safety during the charging process. The protection devices are uniformly arranged in the distribution panel 6 for easy wiring and maintenance. At the same time, the same liquid cooling unit provides cooling for the battery system 4, DC-DC auxiliary power supply, and liquid-cooled charging gun through a three-way connector. The liquid cooling pipe of the liquid-cooled charging gun is equipped with a solenoid valve, controlled by the main control unit 7. When the charging gun is not charging externally, the solenoid valve is closed to prevent the internal liquid cooling pipe temperature from being too low, causing condensation on the charging gun sheath. Finally, the energy storage and charging system frame 1 is made of nine-fold steel with a closed cross-section and high strength. At the same time, the steel is densely covered with sequential holes, providing flexible and convenient installation interfaces for the outer shell and other mounting components.
