In a low temperature environment, the chemical reaction rate of the battery will slow down, resulting in a decrease in the available capacity of the battery. At this time, if the battery continues to be cooled, it may cause the battery to be unable to provide the same amount of power as at normal temperature, and the battery performance will decrease. In view of this, the utility model proposes a parallel battery management system. Utility Model Content

[0026] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0028] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0031] like Figure 1 and Figure 2 As shown, a parallel battery management system proposed by the utility model comprises a box body 1 with an opening at the top, and five groups of U-shaped mounting racks 2 are arranged in the box body 1. The number of the mounting racks 2 is not limited to five groups, and can be an odd group of three or more groups, which is convenient for positioning and installation of the middle group of mounting racks 2. Batteries 21 are installed in the five groups of mounting racks 2, and a temperature sensor is installed on the top of the mounting rack 2 to monitor the temperature of the battery 21. The middle group of mounting racks 2 is fixedly connected to the box body 1, and the other four groups of mounting racks 2 are slidably connected to the box body 1. A cover plate 11 is installed on the top of the box body 1, and the cover plate 11 is used for protection. The cover plate 11 and the bottom of the box body 1 are provided with multiple groups of ventilation holes 12, and the ventilation holes 12 are convenient for air circulation and heat dissipation. Wiring ports 22 are arranged on both sides of each group of mounting racks 2, and the wiring ports 22 are convenient for connecting multiple groups of batteries 21. A slide groove 13 for the wiring port 22 to slide is provided on the side of the box body 1.

[0032] For details, please refer to Figure 2 and Figure 3The management system also includes a connection assembly 3 for connecting five groups of mounting frames 2. The connection assembly 3 includes a first connection plate 31, a second connection plate 32, and a connection shaft 33. The three groups of first connection plates 31 are parallel to each other, and the three groups of first connection plates 31 deflect synchronously. The three groups of second connection plates 32 are also parallel to each other, and the three groups of second connection plates 32 deflect synchronously. The two adjacent groups of first connection plates 31 and second connection plates 32 are rotationally connected through a connection shaft 33, so that multiple groups of first connection plates 31 and second connection plates 32 deflect synchronously. The connection assembly 3 also includes a slider 34 and a limit block 35. The top of the connection shaft 33 that is rotationally connected at both ends of the middle group of first connection plates 31 and the middle group of second connection plates 32 is fixedly connected to a group of sliders 34 respectively, so as to drive the sliders 34 to move synchronously when the first connection plates 31 and the second connection plates 32 deflect. The T-shaped slider 34 is slidably connected between two groups of L-shaped limit blocks 35, and the limit blocks 35 are fixedly connected to the bottom of the mounting frame 2. When the slider 34 moves, it slides smoothly in the limit blocks 35, and at the same time drives the limit blocks 35 and the mounting frame 2 to move. Other connecting shafts 33 are fixedly connected to the bottom of the corresponding mounting frame 2, and multiple groups of mounting frames 2 move synchronously, and the distance between two adjacent groups of mounting frames 2 remains equal.

[0033] Further, such as Figure 2-4 As shown, the management system also includes an adjustment mechanism 4 that cooperates with the connection component 3 to synchronously adjust the positions of the four groups of mounting frames 2 that are slidably arranged. The adjustment mechanism 4 includes a positioning sleeve 41, a threaded rod 42, a threaded sleeve 43, and a servo motor 44. The positioning sleeve 41 is fixedly connected to the bottom of the middle group of connecting shafts 33, and the position of the positioning sleeve 41 is fixed. The threaded rod 42 is rotatably connected in the positioning sleeve 41, and the threaded rod 42 rotates in the original position. The threaded directions of the threaded rods 42 on both sides of the positioning sleeve 41 are opposite, and the two groups of threaded sleeves 43 are symmetrically arranged on both sides of the positioning sleeve 41 and are threadedly connected to the threaded rod 42, so that the threaded rod 42 drives the two groups of threaded sleeves 43 to move closer to or away from each other when rotating. The two groups of threaded sleeves 43 are respectively fixedly connected to the bottom of the two groups of mounting frames 2 on both sides of the middle group of mounting frames 2. When moving, the threaded sleeves 43 drive the two groups of mounting frames 2 to move synchronously, so that the four groups of mounting frames 2 move synchronously. The servo motor 44 is installed on the outside of the box body 1. The output end of the servo motor 44 passes through the side wall of the box body 1 and is fixedly connected to the threaded rod 42. The servo motor 44 is used to drive the threaded rod 42 to rotate. The adjustment mechanism 4 also includes a limit sleeve 45 and a limit rod 46. The four groups of limit sleeves 45 are respectively fixedly connected to the bottom of the two groups of mounting frames 2 away from the center. The limit sleeves 45 move synchronously with the mounting frames 2. The limit rod 46 is slidably connected to the limit sleeve 45. The limit rod 46 is fixedly connected to the box body 1 and is used to limit the mounting frame 2 when it moves, so that the movement of the mounting frame 2 is smooth.

[0034] Finally, multiple groups of cooling fans 5 are installed in the box body 1 to drive air flow for heat dissipation after startup.

[0035] In this embodiment, first, when the temperature sensor detects that the temperature of the battery 21 is too high, the servo motor 44 is started to drive the threaded rod 42 to rotate, and at the same time, the threaded rod 42 drives the two groups of threaded sleeves 43 to move away from each other. At this time, except for a group of mounting frames 2 fixedly set in the center, the other four groups of mounting frames 2 move synchronously and move away from each other, and the two groups of mounting frames 2 away from the center slide smoothly under the limiting action of the limiting sleeve 45 and the limiting rod 46. At the same time, multiple groups of first connecting plates 31 and second connecting plates 32 are driven to deflect synchronously, and the slider 34 is driven to slide in the limiting block 35. At this time, the gap between the two adjacent groups of batteries 21 is increased, which is convenient for the heat generated by the battery 21 to dissipate. At this time, the cooling fan 5 is started to drive the air to enter the box body 1 through the ventilation hole 12 and be discharged. The air takes away the heat when passing through, which plays a role in cooling the battery 21, ensuring the safe and stable operation of the battery 21 and ensuring the service life. At the same time, when the ambient temperature is low, the cooling fan 5 is turned off and the servo motor 44 is started to gather the multiple cooling fans 5, so that the heat generated by the battery 21 during operation is difficult to dissipate, and is balanced with the low temperature of the environment, ensuring that the mounting bracket 2 operates at an appropriate temperature and ensuring the working performance of the battery 21.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
