Description

Technical Field

[0001] This utility model relates to the field of new energy power battery packs and energy storage technology, specifically to a multi-functional battery sampling module. Background Technology

[0002] Currently, the voltage architecture on the market is typically 400V, 800V, or even higher voltage platforms. With the widespread adoption of fast charging and supercharging, and the increasing demands on battery pack heat dissipation, existing battery pack cooling systems usually employ liquid cooling circuits within the casing at the bottom of the cells, dissipating heat through liquid circulation. However, relying solely on bottom-level heat dissipation is insufficient. The battery sampling module lacks heat dissipation, humidity monitoring, anti-condensation, and fire suppression functions. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional battery sampling module.

[0004] The technical solution is as follows: a multi-functional battery sampling module, including a support member, several series aluminum bars on its upper surface, two output aluminum bars, and a collection assembly on the support member; it also includes a liquid cooling plate on the series aluminum bars and the collection assembly; the liquid cooling plate is provided with an inlet and an outlet; the liquid cooling plate is provided with a cooling water inflow space connected to the inlet at one end and a cooling water outflow space connected to the outlet at the other end.

[0005] Preferably, the cooling water inflow space and the cooling water outflow space are separated and connected within one end of the liquid cooling plate; the inlet and outlet are located at the other end of the liquid cooling plate.

[0006] Preferably, a hot-pressed insulating film is further provided on the series aluminum busbar and the acquisition assembly, and the hot-pressed insulating film is located between the liquid cooling plate and the series aluminum busbar and the acquisition assembly.

[0007] Preferably, it further includes an upper hot-pressed insulating film; the upper hot-pressed insulating film is disposed on the upper surface of the liquid cooling plate; the acquisition assembly includes sampling of temperature, humidity and voltage; the acquisition assembly is provided with a humidity sensor.

[0008] Preferably, it also includes a fire extinguishing device disposed on the upper surface of the upper hot-pressed insulating film.

[0009] Preferably, the support member is integrally formed from a mounting plate and two upright plates respectively disposed on both sides thereof; the two side edges of the mounting plate are respectively connected to the upper edges of the two upright plates and the two upright plates are perpendicular to the mounting plate.

[0010] Preferably, a heating film is provided on the surface of both upright plates.

[0011] Preferably, each of the series aluminum busbars is electrically connected to the acquisition assembly; the two output aluminum busbars are respectively located at both ends of the upper surface of the support and are both electrically connected to the acquisition assembly.

[0012] Technical Effects: The sampling module of this invention incorporates an insulating film and a liquid-cooled plate, which provide insulation. The hot-pressed insulating film, after being hot-pressed with the battery sampling module, isolates the liquid-cooled plate from the aluminum busbars and sampling assembly on the battery sample module, providing insulation protection. The liquid-cooled plate is fixed above the hot-pressed insulating film; when the module is working, the liquid-cooled plate activates to dissipate heat. When the battery module temperature is low, the heating film activates to provide heat. A fire extinguishing device is placed above the sampling module for fire suppression. Therefore, compared with existing technologies, this invention has excellent heat dissipation, heating, fire extinguishing, and anti-condensation functions, which helps improve the heat dissipation capacity of the battery pack.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 4As shown, this utility model embodiment provides a multifunctional battery sampling module, including a support member 1, a plurality of series aluminum bars 2 disposed on its upper surface, two output aluminum bars 3, and a collection assembly 4 disposed on the support member; it also includes a liquid cooling plate 5 disposed on the series aluminum bars 2 and the collection assembly 4; the liquid cooling plate is provided with an inlet 501 and an outlet 502; the liquid cooling plate is provided with a cooling water inflow space connected to the inlet 501 at one end and a cooling water outflow space connected to the outlet 502 at the other end.

[0021] like Figure 4 As shown, specifically, each of the series aluminum busbars 2 is electrically connected to the acquisition assembly 4; the two output aluminum busbars 3 are respectively located at both ends of the upper surface of the support member 1 and are both electrically connected to the acquisition assembly 4.

[0022] The data acquisition assembly 4 includes sampling of temperature, humidity, and voltage; the data acquisition assembly is equipped with a humidity sensor 10; depending on the scheme, it includes the following versions:

[0023] a. Wire harness version: connector, connector terminal, cable or connector, connector terminal, cable, nickel plate terminal, temperature sensor, humidity sensor;

[0024] b. FPCA version: Connector, FPC, nickel strip, temperature sensor, humidity sensor;

[0025] c. PCBA version: connector, PCB, nickel strip, temperature sensor, humidity sensor;

[0026] d. FDC version: connector, FDC, nickel strip, temperature sensor, humidity sensor;

[0027] e. FCC version: FFC, FDC, connectors and connector terminals, temperature sensors, humidity sensors.

[0028] Specifically, if Figure 5 As shown, the cooling water inflow space and the cooling water outflow space are separated and connected at one end of the liquid cooling plate 5; the inlet 501 and the outlet 502 are located at the other end of the liquid cooling plate (5). When the module is working, the liquid cooling plate starts to work and plays a role in heat dissipation; the coolant enters through the inlet 501, flows around once, and then flows out from the outlet 502 to dissipate heat.

[0029] A hot-pressed insulating film 6 is also provided on the series aluminum busbar 2 and the acquisition assembly 4. The hot-pressed insulating film is located between the liquid cooling plate 5 and the series aluminum busbar 2 and the acquisition assembly 4. After the hot-pressed insulating film 6 is hot-pressed with the battery sampling module, it can isolate the liquid cooling plate 5 from the series aluminum busbar 2 and the acquisition assembly 4 on the battery sample module for insulation protection.

[0030] It also includes an upper hot-pressed insulating film 7; the upper hot-pressed insulating film is disposed on the upper surface of the liquid cooling plate 5; after the upper hot-pressed insulating film is laminated, the liquid cooling plate 5 can be fixed to the battery sampling module.

[0031] like Figure 1-3 As shown, in order to extinguish the fire in the sampling module, a fire extinguishing device 8 is also included, which is located on the upper surface of the upper hot-pressed insulating film 7. It has a built-in sensor and dry powder. When the sensor detects a sharp rise in temperature or fire, the fire extinguishing device explodes, and the dry powder covers the entire module to achieve the fire extinguishing effect.

[0032] like Figure 4 As shown, in this embodiment, the support member 1 is integrally formed from a mounting plate 101 and upright plates 102 respectively disposed on both sides thereof; the two side edges of the mounting plate are respectively connected to the upper edges of the two upright plates and the two upright plates are perpendicular to the mounting plate.

[0033] Heating films 9 are provided on the surfaces of both upright plates 102. When the battery module temperature is low, the heating films 9 work to provide heat. When the battery module temperature is high, the heating films stop working and the liquid cooling plates 5 start working to dissipate heat. Temperature control can be achieved through the cycle between the heating films and the liquid cooling plates. When the temperature change is small or constant, condensation can be prevented.

[0034] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.

[0035] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
