Technical Field
[0001] This utility model relates to the field of vehicle battery pack technology, specifically a novel modular vehicle battery pack. Background Technology
[0002] In the past decade, with the vigorous development of lithium batteries, lithium batteries in energy storage systems have gradually replaced some of the old energy markets, and vehicle battery packs, as part of energy storage systems, have also gained market recognition. Compared with traditional energy storage systems, vehicle battery packs are not limited to a fixed area, are more flexible and convenient, and provide power to electrical equipment continuously in both parked and driving states, greatly meeting various power needs.
[0003] The vehicle battery pack includes a cabinet, cabinet door, mounting frame, control module, and unit battery modules. The mounting frame, control module, and unit battery modules are all housed in the cabinet. Mounting holes allow the control module and unit battery modules to be neatly installed in the cabinet. Multiple unit battery modules are installed in the cabinet and connected in series. The high-voltage control box controls the input and output.
[0004] Regarding the aforementioned technical conditions, there is still a drawback: the vehicle battery pack generates heat during operation, and excessive heat can affect the normal use of the vehicle battery pack. It is necessary to dissipate the heat in the vehicle battery pack in a timely manner, but the heat dissipation effect of the vehicle battery pack is not good enough.
[0005] Based on this, this utility model designs a novel modular vehicle battery pack to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a novel modular vehicle battery pack to solve the aforementioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel modular vehicle battery pack, comprising a cabinet, a cabinet door, a high-voltage control box, unit battery modules, and a mounting frame. The cabinet door is disposed on the cabinet, and multiple mounting frames are disposed within the cabinet. The high-voltage control box is disposed within the mounting frame, and multiple unit battery modules are disposed within the mounting frame. A cooling fan is disposed on the side of each unit battery module near the cabinet door, and multiple air vents are provided on the side of each unit battery module away from the cabinet door. Multiple exhaust fans are disposed on the top of the cabinet, and a back panel is disposed on the cabinet with multiple air inlets.
[0008] Preferably, the mounting frame is rotatably provided with rollers, and multiple rollers are provided on the mounting frame.
[0009] Preferably, the unit battery module has a maintenance port on the side near the cabinet door.
[0010] Preferably, a mounting bracket is fixedly installed in the cabinet, and the mounting frame is fixedly installed on the mounting bracket, with a certain gap between the mounting frame and the side wall of the cabinet.
[0011] Preferably, the outer casing of the unit battery module is made of aluminum plate with a thickness of 2mm.
[0012] Preferably, the outer shell of the high-voltage control box is made of aluminum plate with a thickness of 2mm.
[0013] Preferably, the cabinet is provided with a side panel, and the side panel is provided with multiple air inlets.
[0014] In summary, this application has the following beneficial technical effects: During use, the exhaust fan is activated, and air from outside the cabinet enters the cabinet through the air inlet and air vent. At the same time, the cooling fan is activated, and the air entering the cabinet enters the unit battery module through the vent, and finally exits from the unit battery module through the cooling fan. The air exiting the unit battery module carries away some of the heat from the unit battery module. Afterwards, the air circulates between the cabinet and the unit battery module before being exhausted from the cabinet by the exhaust fan. The air exiting the cabinet carries away the heat from the cabinet. Thus, through the coordinated action of the cooling fan and vent, and the exhaust fan and air inlet and air vent, the heat in the high-voltage control box and unit battery module within the cabinet is better dissipated, and heat is less likely to accumulate in the cabinet and unit battery module, thereby improving the heat dissipation effect of the vehicle battery pack.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0026] A novel modular vehicle-mounted battery pack includes a cabinet 5, a cabinet door 2, a high-voltage control box 8, unit battery modules 9, and mounting frames 11. The cabinet door 2 is mounted on the cabinet 5, and multiple mounting frames 11 are disposed within the cabinet 5. The high-voltage control box 8 is disposed within the mounting frame 11, and multiple unit battery modules 9 are disposed within the mounting frame 11.
[0027] A cooling fan 13 is provided on the side of the unit battery module 9 closest to the cabinet door 2, and multiple air holes 15 are provided on the side of the unit battery module 9 away from the cabinet door 2. When the cooling fan 13 is turned on, outside air enters the unit battery module 9 through the air holes 15 and is then discharged through the cooling fan 13. The discharged air carries away some of the heat from the unit control module and dissipates heat from the unit battery module 9.
[0028] Multiple exhaust fans 1 are installed on the top of the cabinet 5, and a back panel 6 is installed on the cabinet 5, with multiple air inlets 7 on the back panel 6. When the exhaust fans 1 are turned on, air from outside the cabinet 5 enters the cabinet 5 through the air inlets 7 and is finally exhausted from the cabinet 5 through the exhaust fans 1. The air exhausted from the cabinet 5 carries away some of the heat from the unit battery module 9 in the cabinet 5. With the combined action of the exhaust fans 1, air inlets 7, cooling fans 13 and air vents 15, the cabinet 5, the high-voltage control box 8 and the unit battery module 9 can achieve better heat dissipation, improving the heat dissipation effect.
[0029] Rollers 14 are rotatably mounted on the mounting frame 11. Multiple rollers 14 are provided on the mounting frame 11. The rollers 14 facilitate the installation of the high-voltage control box 8 and the unit battery module 9 in the cabinet 5. A maintenance port is provided on the side of the unit battery module 9 near the cabinet door 2, which allows for real-time monitoring and maintenance (charging and discharging) of the internal lithium battery without disassembling the unit battery module 9.
[0030] A mounting bracket 10 is fixedly installed in the cabinet 5, and a mounting frame 11 is fixedly installed on the cabinet. The mounting bracket 10 creates a certain gap between the mounting frame 11 and the side wall of the cabinet 5, so that the air entering the cabinet 5 from the air inlet 7 can circulate between the unit battery module 9 and the cabinet 5, thus improving air heat dissipation.
[0031] The casing of the power battery module is made of aluminum plate with a thickness of 2mm, reducing the weight of the unit battery module 9 and facilitating later maintenance. The casing of the high-voltage control box 8 is also made of aluminum plate with a thickness of 2mm, reducing its weight and facilitating later maintenance. A side panel 3 is provided on the cabinet 5, with multiple air inlets 4. These air inlets 4, along with the air inlet 7 and exhaust fan 1, work together to better dissipate heat from the unit battery module 9 and the high-voltage control box 8 within the cabinet 5.
[0032] The implementation principle of this embodiment is as follows: During use, the exhaust fan 1 is turned on, and air from outside the cabinet 5 enters the cabinet 5 through the air inlet 7 and the air inlet hole 4. At the same time, the cooling fan 13 is turned on, and the air entering the cabinet 5 enters the unit battery module 9 through the air vent 15. Finally, the air is discharged from the unit battery module 9 through the cooling fan 13, and the air discharged from the unit battery module 9 carries away some of the heat from the unit battery module 9. Afterwards, the air circulates between the cabinet 5 and the unit battery module 9 and is discharged from the cabinet 5 through the exhaust fan 1. The air discharged from the cabinet 5 carries away the heat in the cabinet 5. In this way, with the coordinated action of the cooling fan 13 and the air vent 15, the exhaust fan 1 and the air inlet 7 and the air inlet hole 4, the heat in the cabinet 5 is better dissipated, and the heat is less likely to accumulate in the cabinet 5 and the unit battery module 9, thereby improving the heat dissipation effect of the vehicle battery pack.
