Detailed Implementation
[0025] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0026] like Figures 1-4 As shown, a high-power, high-capacity backup battery system includes a housing 1, a DC panel 2, a side-mounted module 3, a heat sink 4, and a fan 5. The housing 1 is a hollow structure with an opening on the left. The DC panel 2 is installed at the opening of the housing 1 and integrates a boost BMS module. The side-mounted module 3 is located inside the right side of the housing 1 and is connected to the boost BMS module. The side-mounted module 3 includes multiple side-mounted high-capacity battery cells 31. The heat sink 4 is distributed on the left side of the DC panel 2. A reserved space is provided on the left side of the housing 1, and the fan 5 is located in the reserved space. Several air inlets 11 are opened at the left end of the upper side panel of the housing 1, and several air outlets 12 corresponding to the fan 5 are opened on its front side panel. By using high-capacity battery cells 31 and placing them sideways, the number of battery cells is reduced, and the overall height of the system is also reduced. At the same time, the arrangement of the heat sink 4 and the fan 5 achieves two-stage heat dissipation of the system, significantly improving the heat dissipation effect of the system. In addition, the reserved space can be used for supporting equipment such as fire extinguishing devices and GPS, improving the system's practicality. Specifically, there are two sets of side-mounted modules 3, with multiple high-capacity battery cells 31 connected in series; there are two fans 5; the front end of the DC panel 2 integrates terminals 7; the boost BMS integrated module can achieve high-power, high-capacity boost, and can flexibly use different cell capacities to meet the energy needs of the battery system.
[0027] like Figure 1 and Figure 4 As shown, the heat sink 4 includes linear fins 41 and V-shaped fins 42. Several linear fins 41 are distributed at the front and rear of the DC panel 2, while multiple V-shaped fins 42 are located in the center of the DC panel 2. Specifically, the multiple V-shaped fins 42 are symmetrically arranged, forming an "X" shape, making the system easily identifiable. The V-shaped fins 42 further increase the heat dissipation area and improve the heat dissipation effect.
[0028] like Figure 3 and Figure 5As shown in the figure, the side-mounted module 3 further includes side-mounted end plates 32, steel belts 33, lead-out terminals 34, and insulating PC 35. The side-mounted end plates 32 are respectively arranged on the left and right sides of multiple large-capacity battery cells 31. The steel belts 33 integrally bind the large-capacity battery cells 31 and the side-mounted end plates 32. The lead-out terminals 34 are installed on the side-mounted end plates 32. The large-capacity battery cells 31, side-mounted end plates 32, steel belts 33, and lead-out terminals 34 are integrally arranged within the insulating PC 35. The arrangement of the side-mounted end plates 32 and the steel belts 33 realizes the fixation and limitation of the side-mounted module 3. Specifically, the insulating PC 35 is in a "U" shape, achieving three-sided insulation of the side-mounted module 3 and ensuring the insulation effect; the insulating PC 35 in two groups of side-mounted modules 3 is arranged oppositely.
[0029] As Figure 5 shown, the lead-out terminals 34 on the left side of several side-mounted modules 3 are connected to the DC panel 2, and the lead-out terminals 34 on the right side thereof are connected through a series copper bar 6. The series copper bar 6 is connected to the lead-out terminals 34 on the right side, transferring the torque of the screw from the aluminum bar, so that the acting force of the worker when applying torque is not on the aluminum bar, avoiding problems such as loosening and dropping of the aluminum bar due to various reasons.
[0030] As Figure 5 shown, in order to facilitate the connection of the total positive and negative poles to the series copper bar 6, a number of strip-shaped gaps 351 are provided on the insulating PC 35.
[0031] As Figure 1 and Figure 3 shown, hanging ears 8 are respectively installed at the left ends of the front and rear side plates of the box body 1, and handles 9 are respectively installed at the left ends of its upper and lower side plates. Among them, the hanging ears 8 have the functions of both the handles 9 and fixing the box body 1.
[0032] As Figure 2 shown, the left end of the lower side plate of the box body 1 is connected to the bottom end of the DC panel 2 through a bending plate 10. The setting of the bending plate 10 is compatible with the DC panel 2, increasing the structural strength of the entire system, saving the usage amount of sheet metal parts, and reducing the cost.
[0033] During operation, the heat sink 4 performs primary heat dissipation on the system. When the system temperature is too high and the heat sink 4 cannot meet the timely heat dissipation, the fan 5 starts, sucks air from the air inlet 11, and blows air to the air outlet 12 to achieve secondary heat dissipation.
[0034] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
