[0042] In one embodiment, please refer to Figure 2, the above-mentioned battery pack 20 includes a battery box body, batteries, a BMS module, and a DCDC buck converter module; the BMS module is connected to the DCDC buck converter module; the batteries are connected to the DCDC buck converter module; the batteries, the BMS module, and the DCDC buck converter module are respectively disposed inside the battery box body; the BMS modules of adjacent battery packs 20 are electrically connected through a plug 23; the battery box body is connected with a mechanical lock 40.

[0043] In one embodiment, please refer to Figure 2 , the above-mentioned BMS module is connected to a miniature circuit breaker.

[0044] In one embodiment, please refer to Figure 1 , the upper end surface of the above-mentioned battery box body is provided with a jack 22, and the lower end surface of the battery box body is provided with a guide post 21, and the guide post 21 is inserted into the jack 22 on the upper end surface of the adjacent battery box body.

[0045] In this embodiment, each battery pack 20 has a distributed power supply function and can be used alone to provide users with flexible and diverse power solutions. Each battery pack 20 is designed with convenience and practicality in mind, equipped with a lighting function, suitable for emergency or off-grid environments, and meets the basic light source needs of users in the dark or dim environment.

[0047] In summary, this stacked intelligent mobile outdoor power supply device combines flexibility, safety, portability, and high efficiency, and is suitable for the power supply needs in various outdoor scenarios, being a comprehensive and practical power solution.

[0048] In this embodiment, the battery pack 20 further includes an MCU, and the MCU is connected to the BMS module.

[0049] In this embodiment, the mechanical latch 40 and the reset button are provided to avoid possible damage during hot plugging. When the user needs to perform operations such as component stacking or separation, the reset button must be manually pressed first. This action will open the mechanical latch 40, allowing the safe connection or disconnection between the main control box 10 and the battery pack 20, as well as between the battery packs 20. At the same time, the operation of the reset button will trigger the MCU in the BMS inside each battery pack 20, causing the system power supply MOS transistor and the power supply MOS transistor for power to be actively cut off. These two MOS transistors are placed in the BMS module. This strategy ensures that there is no current flow on the P+ and P- power lines during the process of component separation or stacking, effectively preventing electrical damage that may be caused by hot plugging. This innovative safety mechanism effectively guarantees the stability and long-term reliability of the system.

[0050] In addition, this embodiment also provides the working process of the device, specifically including:

[0051] Power-on and initialization of the main box body and the battery pack 20; specifically, when the system starts up, all the battery packs 20 are awakened and the internal BMS module performs self-check. The main control module ensures that the battery pack 20 with the highest voltage supplies power to the main control module first by controlling the closing of the MOS tube. If the power supply of the battery pack 20 with the highest voltage fails, it will automatically switch to the battery pack 20 with the second highest voltage to ensure stable power supply of the system.

[0052] Next, communication and detection of the battery pack 20 are carried out. Specifically, after the main control module starts up, it performs communication addressing on all the battery packs 20 and records the number of successfully addressed battery packs 20. The LCD screen displays the addressing result to remind the user to check whether the actual number of battery packs 20 is consistent with the expected value to ensure the effective utilization of system resources.

[0053] Then, intelligent charge and discharge management is carried out. Specifically, the voltage, current, and temperature states of each battery pack 20 are monitored; the balanced charge and discharge strategy of the battery pack 20 is implemented, and by controlling the opening and closing of the main MOS tube, the state of charge (SOC) of each battery pack 20 is ensured to be close to the same, preventing overcharging or over-discharging and extending the battery service life.

[0054] Furthermore, dynamic load distribution and fault handling are carried out. Specifically, according to factors such as the capacity, health status, and temperature of the battery pack 20, the load is dynamically distributed to ensure that the working pressure of each battery pack 20 is evenly distributed. When a fault or alarm of the battery pack 20 is detected, the main control module performs delayed processing and switches the battery pack 20 to ensure continuous power supply of the main circuit.

[0055] In addition, an intelligent charging strategy is also executed. Specifically, according to the total demand and the status of each battery pack 20, a priority charging plan is formulated. The battery pack 20 with low battery power or poor status is preferentially charged, or an interleaved charging method is adopted to avoid problems caused by concentrated charging, such as overheating.

[0056] Finally, fault prediction and early warning are also carried out. Specifically, using data analysis and machine learning algorithms, the performance degradation trend of the battery pack 20 is predicted. An early fault warning is issued in advance, and preventive maintenance measures are recommended to ensure the stable operation of the system and the extension of the equipment life.

[0057] In this embodiment, after the system is powered on, all the battery packs 20 are first awakened, and the self-check of the battery management system (BMS module) is carried out. Subsequently, the BMS module controls the power supply MOS of the main control module of each battery pack 20 to be closed to ensure that the M+ / M- system is powered on. A diode competition power supply mechanism is adopted in this circuit to preferentially supply power to the main control module with the battery pack 20 having the highest voltage. If a power supply fault occurs in the battery pack 20 with the highest voltage, the system will automatically switch to the battery pack 20 with the second highest voltage to ensure the reliable operation of the main control module.

[0058] After the main control module is started, it conducts communication addressing allocation for all awakened battery packs 20 and records the number of successfully addressed battery packs 20. This information will be displayed on the LCD screen to remind the user to check the actual number of battery packs 20 and avoid resource waste caused by unsuccessful addressing of some battery packs 20 for a long time. The main control module also conducts self-check on the entire outdoor power supply system, including monitoring the status of each battery pack 20, such as voltage, temperature, and SOC (State of Charge).

[0059] During the intelligent charge and discharge management process, the intelligent discharge strategy includes: the main control module monitors the status of each battery pack 20, such as voltage, current, and temperature, according to the software algorithm, and implements the balanced charge and discharge strategy for the battery pack 20. When the battery pack 20 with the highest voltage closes the main MOS tube to supply power to the P+ / P- system, if it is detected that the closing fails, the system will control the MOS tube of the current battery pack 20 to disconnect and try the battery pack 20 with the second highest voltage. During the discharge process, the system ensures that the voltage difference of the battery pack 20 is within the set allowable range to avoid equipment damage caused by circulating current.

[0060] Dynamic load allocation, fault isolation and switching: When multiple battery packs 20 are in parallel to supply power, the main control module dynamically determines the current output according to factors such as the capacity, health status, and temperature of each battery pack 20. When a fault or alarm of the battery pack 20 is detected, the system will delay and then turn off the MOS tube of the faulty battery pack 20 and switch to the battery pack 20 with the second highest voltage to ensure the continuity and safety of the power supply of the P+ / P- main circuit.

[0061] Intelligent charging strategy: The main control module formulates a charging plan according to the total required power and the status of each battery pack 20. It preferentially charges the battery pack 20 with low power or poor status, or adopts an interleaved charging method to avoid problems such as excessive heating.

[0062] The above content realizes the high efficiency, safety and reliability during the parallel operation of the battery packs 20, and avoids large circulating current in the parallel operation of multiple battery packs 20 and equipment damage when the voltages of several battery packs 20 are inconsistent.

[0063] The model of the main control module is KF32F350MQV; the model of the BMS module is FM33LG048.
