The VPX module structure is a structure conforming to the VPX bus system, and is used for packaging the lithium battery cell 11 and the PCB control board 12.

[0052] It can be understood that the lithium battery cell 11 is an electric cell composed of a plurality of lithium ion batteries in a series-parallel manner, as shown in FIG. 1. Figure 2 As shown in FIG. 1, the number of lithium ion batteries and the series-parallel manner thereof can be determined according to the required supply voltage provided by the lithium battery module 100 based on the VPX architecture, and the specific type of lithium ion battery can not be limited in the present specification, as long as the required supply voltage can be assembled. The series-parallel manner can be understood by referring to the existing series-parallel assembly manner of the lithium battery pack.

[0054] It should be noted that the sampling circuit 121 can adopt existing signal sampling circuit 121 or device to realize online monitoring of the electrical signal and working temperature of the lithium battery cell 11 during the working process. The sampling circuit 121 can also integrate commonly used voltage / current limiting devices and temperature limiting devices, such as but not limited to commonly used voltage limiter, current limiter and heat dissipation semiconductor, to limit the working voltage range and working temperature range of the lithium battery cell 11, and reduce the risk of abnormal working of the lithium battery cell 11. The sampling circuit 121 can include multiple sub-sampling circuits 121 or devices, which can be selected and used according to the actual sampling and limiting needs.

[0055] The auxiliary power supply circuit 122 refers to a circuit or device that draws a path from the output power supply voltage of the lithium battery cell 11 and converts it into a power supply voltage required for the working of the sampling circuit 121 and the single-chip microcomputer 125. The auxiliary power supply circuit 122 can adopt a conventional power adapter or conversion circuit in the art, and the specific selection can be determined according to the power supply voltage required for the working of the sampling circuit 121 and the single-chip microcomputer 125.

[0056] The drive amplification circuit 123 is an amplification circuit that provides amplification to the output power supply voltage of the lithium battery cell 11 and increases the delay time length of the delay start control function. It works under the control signal (also known as drive signal) provided by the single-chip microcomputer 125 to ensure the power supply capability of the lithium battery module 100 based on the VPX architecture to the capacitive load. The drive amplification circuit 123 can adopt existing output voltage amplification and delay start circuit modules or devices, such as Figure 1 As shown in the figure, one of the optional existing drive amplification circuits 123 is adopted.

[0058] The VPX module structure 13 is a unified packaging structure for mounting and fixing the above components and providing environmental protection. The VPX module structure 13 is designed to reliably arrange the lithium battery cell 11 and the PCB control board 12, and is provided with an external connection port for installing the module VPX connector 126, so as to facilitate the connection between the lithium battery module 100 based on the VPX architecture and the power-consuming equipment in the VPX chassis. The VPX module structure 13 can be integrally formed by using a high-thermal-conductivity material, or can be assembled by using separate components through screws, buckles and / or sealant, etc. The specific shape of the VPX module structure 13 is not limited in the present specification, and the shape and size thereof can be determined according to the mounting requirements of the VPX chassis to be applied, as long as the lithium battery cell 11 and the PCB control board 12 can be reliably arranged, the VPX bus system requirements are met, and the VPX chassis can be detachably mounted.

[0059] Specifically, when the power-consuming equipment in the VPX chassis needs to be powered, the single-chip microcomputer 125 works under the direct power supply of the auxiliary power supply circuit 122, can receive a corresponding power supply instruction through the communication circuit 124, and then outputs the power supply voltage of the lithium battery cell 11 to the power-consuming equipment through the driving amplifier circuit 123 and the module VPX connector 126. While the lithium battery cell 11 is working, the sampling circuit 121 works under the direct power supply of the auxiliary power supply circuit 122, samples the voltage, current and temperature signals of the lithium battery cell 11, and reports the sampling data to the single-chip microcomputer 125 for processing. The sampling circuit 121 limits the working voltage and working temperature range of the lithium battery cell 11 during the sampling process, so as to prevent the lithium battery cell 11 from working abnormally, such as under-voltage output, over-voltage output or over-temperature. The single-chip microcomputer 125 can monitor the working state of the lithium battery cell 11 according to the sampling data, and can also output the working state of the lithium battery cell 11 to the outside through the communication circuit 124 and the module VPX connector 126, so as to facilitate the VPX chassis or the external terminal to obtain the working state of the lithium battery cell 11 in real time and to perform battery management when necessary.

[0060] The above lithium battery module 100 based on the VPX architecture adopts the lithium battery cell 11, the PCB control board 12 and the VPX module structure 13 to form the VPX architecture modular design lithium battery module, and provides the power supply meeting the VPX bus specification for the VPX case in the case of no external working voltage of the whole machine equipment. The lithium battery cell 11 and the PCB control board 12 are used as the core components of the module, the PCB control board 12 monitors the working state of the lithium battery cell 11 and provides the module VPX connector 126 based on the VPX bus signal definition, realizes the general power supply for the power equipment of the VPX case, and the VPX module structure 13 meeting the VPX bus system is used as the structure of the whole module packaging, so that the general requirement in the VPX case is met, the strong adaptability and the maintainability are achieved, the effect of meeting the VPX bus specification and having the strong general performance in the VPX bus system is achieved.

[0061] In one embodiment, as shown in Figure 3 The sampling circuit 121 includes a battery voltage sampling circuit 1211, a battery current sampling circuit 1212 and a temperature sampling circuit 1213. The battery voltage sampling circuit 1211 is connected to the lithium battery cell 11, the auxiliary power supply circuit 122 and the single-chip microcomputer 125 respectively. The battery current sampling circuit 1212 is connected to the lithium battery cell 11 and the single-chip microcomputer 125 respectively, and the temperature sampling circuit 1213 is connected to the single-chip microcomputer 125. The battery voltage sampling circuit 1211 is used for sampling the voltage of the lithium battery cell 11, the battery current sampling circuit 1212 is used for sampling the current of the lithium battery cell 11, and the temperature sampling circuit 1213 is used for sampling the temperature of the lithium battery cell 11.

[0062] Optionally, in the embodiment, three signal sampling circuits 121, i.e. battery voltage sampling circuit 1211, battery current sampling circuit 1212 and temperature sampling circuit 1213, are adopted to respectively realize battery voltage sampling, battery current sampling and battery temperature sampling of the lithium battery cell 11, so that the single-chip microcomputer 125 can more accurately monitor the working state of the lithium battery cell 11 according to the data such as battery voltage, battery current and battery temperature of the lithium battery cell 11. The battery voltage sampling circuit 1211 and the battery current sampling circuit 1212 can each adopt an analog sampling circuit 121 or a device in the art, which can convert the analog voltage and current signals into corresponding digital signals after sampling, so that the single-chip microcomputer 125 can directly process. The sampling terminals of the battery voltage sampling circuit 1211 can be connected to the positive and negative poles of each lithium ion battery of the lithium battery cell 11 to directly sample the voltage of each lithium ion battery. The battery current sampling circuit 1212 can be connected to the output loop of the lithium battery cell 11 through a sampling resistor to directly sample the current of the lithium battery cell 11. The temperature sampling circuit 1213 can adopt an existing digital temperature monitoring device or an analog temperature monitoring device, and the specific selection can be determined according to actual needs.

[0063] In one embodiment, as shown in FIG. 1, Figure 3 the communication circuit 124 includes an RS232 communication interface circuit, an I 2 C interface circuit and a GPIO interface circuit. The RS232 communication interface circuit is connected to the single-chip microcomputer 125 and the module VPX connector 126 respectively. 2 The I 2 C interface circuit is connected to the single-chip microcomputer 125 and the module VPX connector 126 respectively. The GPIO interface circuit is connected to the single-chip microcomputer 125 and the module VPX connector 126 respectively. The module VPX connector 126 is also the input and output connector in Figure 3

[0064] Further, in the embodiment, the three interface circuits, i.e. the RS232 communication interface circuit, the I 2 C interface circuit and the GPIO interface circuit, can be selected to support the communication data transmission requirements of the single-chip microcomputer 125. The foregoing interface circuit technologies are mature and have high reliability, which can effectively improve the data transmission reliability of the lithium battery module 100 based on the VPX architecture.

[0065] In one embodiment, as shown in FIG. 1, Figure 4 the VPX module structure 13 includes an aluminum alloy structure 131 and a heat-conducting silica gel pad 132. The heat-conducting silica gel pad 132 is laid on the heat dissipation surface of the aluminum alloy structure 131, the aluminum alloy structure 131 internally accommodates and fixes the lithium battery cell 11 and the PCB control board 12, and the connecting port of the aluminum alloy structure 131 is used to install the module VPX connector 126.

[0066] It is understandable that the VPX module structural component 13 adopts a reinforced design (such as thickening, using high-strength and high-thermal-conductivity materials, or setting reinforcing ribs) to accommodate the lithium battery cells 11 and the PCB control board 12, and facilitates installation in the VPX chassis. Key structural design considerations for the VPX module structural component 13 may include: reserving mounting ports for standard VPX connectors based on VPX bus signal definitions; and conforming to the mechanical structure of the VPX bus system (such as shape and dimensions).

[0067] Furthermore, in this embodiment, the following is adopted: Figure 4 The aluminum alloy structural component 131 shown is equipped with a thermally conductive silicone pad 132. The thermally conductive silicone pad 132 contacts the heat dissipation surface of the aluminum alloy structural component 131. The whole adopts a heat dissipation design to meet the heat dissipation requirements. This achieves the encapsulation and protection of the lithium battery cell 11 and the PCB control board 12 while providing efficient heat dissipation. It efficiently transfers away the heat generated by the lithium battery cell 11 and the PCB control board 12 during operation, preventing the lithium battery module 100 based on the VPX architecture from overheating and affecting normal use, and improving the working performance of the lithium battery module 100 based on the VPX architecture.

[0068] In some embodiments, the module VPX connector 126 uses the existing VPX20-1111-0004 connector. This VPX connector has a housing made of LCP liquid crystal polymer material and gold-plated copper contacts, featuring a strong connection and low insertion loss, thus improving the performance of the lithium battery module 100 based on the VPX architecture. The signal definitions of this VPX connector are shown in Tables 1 and 2.

[0074] In one embodiment, the aluminum alloy structural component 131 has a standard 6U 5HP dimension. Furthermore, the aluminum alloy structural component 131 adopts a standard 6U 5HP (i.e., width × depth × height of 160mm × 233mm × 25mm), meeting the versatility requirements within the VPX chassis and exhibiting strong adaptability and maintainability.
