It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.

[0023] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0024] See also Figures 1 to 5 The portable mobile emergency power supply of the present invention comprises a bottom plate 10, a lower outer frame 20 is mounted on the bottom plate 10, an upper outer frame 30 and a back plate 40 are connected to the lower outer frame 20, an accommodation space is formed between the lower outer frame 20, the upper outer frame 30 and the back plate 40, a battery assembly 60 is arranged in the accommodation space, a bracket plate 61 is connected to the side of the battery assembly 60, a main board 50 is connected to the bracket plate 61, and the battery assembly 60 is connected to the main board 50.

[0025] The side of the lower outer frame 20 is provided with a parallel interface 25, which is connected to the mainboard 50. The parallel interface 25 is used to connect cables, and multiple portable mobile emergency power supplies of the present invention can be connected at the same time through cables, and up to 8 units can be connected at the same time to achieve power supply capacity expansion. In addition, through the parallel interface 25, it can also be connected to a battery pack with a matching interface to achieve power supply capacity expansion.

[0026] A battery frame 21 is disposed inside the lower outer frame 20 , and the battery assembly 60 is fixedly connected inside the battery frame 21 .

[0027] The battery frame 21 is also provided with an intelligent security module 70, which will be automatically triggered when the power supply temperature is higher than 170° or there is a risk of combustion, release fire extinguishing ions, and extinguish the fire. Protect the power supply safety from the source. The intelligent security module 70 is inside the product. When the temperature generated inside the product reaches the thermal decomposition temperature of the temperature-sensitive material in the product (170 degrees), the product's temperature-sensitive fire-extinguishing composition will undergo a decomposition reaction to produce a large amount of fire-extinguishing substances, including nitrogen, carbon dioxide, and a series of fire-extinguishing particles (the size is at the sub-nanometer level and can float). Nitrogen and carbon dioxide can reduce the oxygen concentration in combustion and play an auxiliary role. The fire-extinguishing particles will undergo physical endothermic processes such as hot melting and gasification, absorb heat at high temperatures, and the flame temperature is reduced, and then radiate to the combustion surface of the combustible material to gasify the combustible molecules, and repeatedly consume a large number of active groups, interrupting the combustible combustion chain, and extinguishing the fire source in a sealed environment as soon as possible.

This unique technical design enables our products to achieve stable and efficient power supply solutions in various environments and conditions.

[0056] The energy storage battery management system (BMS) is an intelligent device that can manage and control energy storage battery packs.

[0061] 4. Optimize battery life: BMS can optimize battery efficiency and extend battery life, for example, by dynamically balancing the charge and discharge status of battery cells to reduce the loss of the entire battery pack and increase its service life.

[0062] In summary, BMS plays an important role in the daily management and control of energy storage battery packs. It can achieve fair distribution of batteries, maintain battery health, protect battery safety, improve battery efficiency and other functions, providing a strong guarantee for the stable and efficient operation of the energy storage system.
