At this time, the third spring 301g is compressed, and the installation of the battery compartment 101 is firmly supported by the installation component 301; when the battery compartment 101 is subjected to severe vibration, at this time, relying on the elastic force of the second spring 301d-2 and the third spring 301g in the installation component 301, the fourth slider 301d-1 drives the hinged connecting rod 301d-5 to swing the first support rod 301d-3 inward all the time, and the fixed block 301d-4 is always moved to both sides under the influence of the elastic force, thereby ensuring that the second support rod 301d-6 hinged on the fixed block 301d-4 always lifts the second mounting plate 301d-8 upward, completing the firm support of the battery compartment 101 during severe vibration, and reducing the impact of vibration on the internal energy storage system of the battery compartment 101. Secondly, the rotating sleeve 302c rotatably connected to the guide column 301d-7 in the buffer assembly, and a plurality of groups of buffer sheets 302d fixedly connected to the rotating sleeve 302c rotate in the buffer solution 302b in the buffer box 302a to provide resistance. The buffer solution 302b can be made of viscous liquid such as glycerin, thereby increasing the rotational friction between the rotating sleeve 302c and the guide column 301d-7, so that the up and down movement of the guide column 301d-7 in the second fixed sleeve 301f is provided with a buffer. The buffer assembly 302 and the mounting assembly 301 work together to ensure that the battery compartment 101 installed on the mounting assembly 301 can not only provide a stable support for the battery compartment 101, but also effectively prevent the battery compartment 101 from being damaged by severe vibrations, such as the battery compartment 101 being detached from the mounting position, causing damage to the entire device, thereby improving the stability of the working operation of the battery compartment energy storage system, and ensuring the energy storage efficiency of the battery compartment energy storage system. It is also safer and more reliable, and has a good use effect.When the battery compartment is transported, the above-mentioned mounting structure can be used to install it on a transport device, so as to prevent the vibration of the transport device from affecting the performance of the battery compartment.

[0062] In summary, the present invention physically isolates the first cavity from the second cavity through the design of a partitioned energy storage unit, effectively avoiding mutual interference between the electrical control and the energy storage device. The early warning unit monitors the temperature change of the battery box in the second cavity in real time through the fire monitor. When abnormal heating or thermal runaway is detected, the fire early warning component is immediately started and sends an alarm signal to the first alarm through the control box. At the same time, the drive motor drives the fire extinguishing tank to quickly locate the fire source for processing. This design ensures that the system can be controlled in time at the early stage of the fire, minimizing the economic losses caused by the fire. The energy storage component adopts a frame-type installation structure, and the third sliders on both sides of the battery box cooperate with the first slide groove on the mounting frame, and a stable positioning is achieved through the combination of springs and card blocks. The operator only needs to press the connecting plate to disengage the card block from the groove, and the battery box can be easily disassembled and assembled by the handle, which greatly simplifies the maintenance process. At the same time, the setting of the partition further improves the standardization and anti-interference ability of the battery box installation, ensuring the efficient implementation of daily maintenance and emergency replacement. The support unit provides all-round stable support through the synergy of the mounting assembly and the buffer assembly. When the system is impacted by external force, the second spring pushes the fourth slider to move in the second slide slot, driving the support rod assembly to disperse the force through the connecting rod, and the third spring provides a horizontal buffering effect. The buffer and buffer sheet in the buffer assembly further reduce the vibration energy, and the design of the rotating sleeve ensures the continuous stability of the buffering effect. This multiple shock-absorbing mechanism effectively prevents severe vibration during transportation and use from damaging the system, significantly extending the service life of the equipment.

[0065] A timer, used to time the working time of the refrigerator 401;

[0071]

[0072] t is the working time of the refrigerator since the last startup; t max is the maximum allowable working time of the refrigerator for a single start-up, M is the number of key position points, T i is the actual detection value of the second temperature sensor at the i-th key position, T i0 T i The rated reference value, ∈ i is the influence coefficient of temperature anomaly at the i-th key position, T a is the actual detection value of the internal temperature of the battery compartment by the first temperature sensor, T b is the actual detection value of the temperature outside the battery compartment by the third temperature sensor, t1 is the time interval between the current startup and the last shutdown of the refrigerator, t2 is the total working time of the refrigerator before the current startup, t3 is the rated required time interval between the current startup and the last startup of the refrigerator (set differently according to t2); h1 is the thermal convection coefficient of the inner surface of the battery compartment; h2 is the thermal convection coefficient of the outer surface of the battery compartment, λ is the average value of the thermal conductivity coefficient of the battery box and the battery material, e is a natural constant, and ln is a natural logarithm; t0 is the unit time; d is the wall thickness of the battery box; S is the heat dissipation area in the battery compartment; P is the power of the refrigerator; T c is the target operating temperature of the battery;

[0073] Determining the remaining working time of the refrigerator after the refrigerator is currently turned on based on the first temperature sensor;

[0074] It should be noted that the timer is used to count the working time of the refrigerator in real time, and to determine the energy storage status of the current battery compartment energy storage system before cooling the inside of the battery compartment each time. When the performance status is abnormal (for example, the remaining working time of the refrigerator after the last startup is less than the working time required for the current heat dissipation), the timer is used to count the working time of the refrigerator in real time.

[0075] ), based on the second alarm, a reminder is given to overhaul the refrigerator, or to dissipate heat through other heat dissipation methods, thereby ensuring the safety of the battery compartment energy storage system.

[0076] It should be noted that when determining the current maximum allowable remaining single working time of the refrigerator, it is based on: the working time of the refrigerator after the current startup, the rated maximum allowable working time of the refrigerator for a single startup, the total working time of the refrigerator before the current startup, and the time interval between the current startup and the last shutdown of the refrigerator; the time period that the refrigerator can continue to work in the current state is determined, and the calculation is reliable.

[0077] It should also be noted that when calculating the working time required for the current heat dissipation, it is based on: the thermal convection coefficient of the outer surface of the battery compartment, the thermal convection coefficient of the inner surface of the battery compartment, the average value of the thermal conductivity coefficient of the battery box and the battery material, the target operating temperature of the battery, the ambient temperature, and the temperature of key positions. The time required for heat dissipation of the current battery compartment state is determined based on the heating state of the key positions, the heat dissipation state of the battery compartment related parameters, the ambient temperature, and the target operating temperature of the battery, and the calculation is reliable.
