Description

Technical Field

[0001] This application relates to the electrical field, and more particularly to a high-voltage connector and electrical equipment. Background Technology

[0002] This application designs a high-voltage connector, primarily for applications in large-scale energy storage systems and high-power electrical equipment. As a core component for power output, the high-voltage connector must ensure safe and reliable electrical connections under high voltage and high current conditions. Simultaneously, the energy storage system needs to monitor current fluctuations and contact temperature changes during charging and discharging in real time to prevent electrical faults or fire risks caused by overcurrent or overheating.

[0003] In related technologies, current sensing devices and temperature sensors are mostly independent modules, requiring additional cabling and occupying system space, resulting in low equipment integration and a bloated system structure. High transmission delay of current signals over long distances affects the timeliness of overcurrent protection, and temperature sensor failure necessitates disassembling the entire electrical compartment, complicating maintenance.

[0004] Therefore, there is an urgent need for a high-voltage connector with real-time sensing capabilities to meet the core requirements of energy storage systems in terms of safety, reliability, and intelligent operation and maintenance. Summary of the Invention

[0005] In a first aspect, embodiments of this application provide a high-voltage connector with integrated detection components, which achieves the effects of compact structure, high integration and real-time sensing capability.

[0006] For example, a high-voltage connector includes a connection body, a connection terminal, and a detection element; the connection terminal is disposed on the connection body and is used for at least electrical connection to an external circuit; the detection element is disposed on the connection body and is used for at least acquiring the status parameters of the connection terminal.

[0007] The above settings, based on achieving reliable connection of high-voltage circuits, monitor the operating status of connection terminals in real time, play a role in space optimization, reduce delay, improve detection performance, and ultimately achieve the effects of improving safety, reducing failure risk, and facilitating operation and maintenance management.

[0008] For example, the connection body is provided with a sensing groove for accommodating the detection component; the sensing groove provides a dedicated installation space for the detection component, eliminating the need for additional cable installation, thus achieving an integrated structural design and simplifying the overall assembly process of the high-voltage connector.

[0009] The connecting terminal passes through the bottom surface of the sensing slot, with at least a portion of the connecting terminal extending out of the slot opening. The design of incorporating the sensing slot in the connecting body and coordinating the connecting terminal's placement aims to optimize the installation and positioning accuracy of the sensing element, while also ensuring the compact structure and operational reliability of the high-voltage connector.

[0010] For example, the detection element includes a current detection element; the current detection element is disposed on the bottom surface of the sensing groove, and the current detection element is used at least to acquire the current of the connection terminal. This ensures accurate and stable acquisition of real-time current data of the connection terminal, while also guaranteeing the compatibility of the detection function with the overall structure of the high-voltage connector.

[0011] For example, the current sensing element is configured as a Hall-type sensing element or a fluxgate-type sensing element. By configuring the current sensing element as a Hall-type sensing element or a fluxgate-type sensing element, the core function is to achieve non-contact and accurate measurement of the current of the high-voltage connector, adapt to the safety monitoring requirements of high-current scenarios, and at the same time take into account the detection stability and structural compatibility.

[0012] For example, the current sensing element is provided with a sensing port, and the connecting terminal passes through the sensing port; the current sensing element does not contact the connecting terminal, and the current sensing element can obtain the current of the connecting terminal based on the magnetic effect of the connecting terminal.

[0013] It does not require direct contact with the high-voltage conductive parts of the connection terminal. The connection terminal also serves as the primary conductor of the current detection device, eliminating the need for additional sampling cables. Unlike existing current detection equipment, it detects the current magnitude solely by sensing the magnetic field generated when the connection terminal is energized, based on the principle of electromagnetic induction.

[0014] On the one hand, Hall effect and fluxgate magnetometer sensors are generally small in size and can be directly embedded in the sensing slot. The connection terminal also serves as a primary conductor. The current sensing device calculates the current at the connection terminal by detecting the magnetic field strength at the connection terminal, achieving a high degree of integration. At the same time, the use of electromagnetic induction avoids the risk of insulation breakdown caused by connecting the sensing device to a high-voltage circuit, thus meeting the safety requirements of high-voltage connectors.

[0015] For example, within the bottom surface of the sensing slot, the distance between the current sensing element and the connection terminal is less than or equal to 1 mm; ensuring effective magnetic flux coupling.

[0016] For example, the inner wall of the sensing groove is provided with a shielding layer to achieve electromagnetic shielding.

[0017] And / or, a fixing adhesive is provided on the bottom surface of the sensing groove, and the current sensing element is disposed within the fixing adhesive. This enhances the installation stability of the sensor and further optimizes the structural protection capability of the high-voltage connector to resist vibration and shock.

[0018] For example, the detection element includes a temperature sensor, which is used at least to acquire the temperature of the connection terminal. This avoids signal delay, monitors the heating status of the connection terminal in real time, provides early warning of thermal failure risks, and ensures the safe and stable operation of the high-voltage circuit.

[0019] For example, the number of temperature sensors is multiple, and the multiple temperature sensors are disposed on the side wall of the sensing groove. This enables full-range and accurate detection of the temperature of the connection terminals, eliminates temperature measurement blind spots, and improves the reliability and timeliness of thermal fault early warning.

[0020] Secondly, this application provides an electrical device including the high-voltage connector described in any of the above possible embodiments of this application; aiming to improve the safety, reliability and intelligence level of the high-voltage power supply system of the device, while reducing operation and maintenance costs and adapting to complex working conditions.

[0021] The high-voltage connector and electrical equipment provided in this application achieve a stable electrical connection between the two by setting the connection terminals on the connection body and using the connection terminals for at least electrical connection to an external circuit, thus meeting the power supply requirements of high-voltage equipment. By setting the connection body as a carrier and integrating detection components, an integrated design of connection and monitoring is achieved, avoiding signal delay, complex maintenance, and bloated system structure.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] First, let me explain the terms used in this application:

[0034] High-voltage connectors: Electrical interface components specifically designed for transmitting high voltage and high current. Their core function is to achieve safe and reliable electrical connection and physical isolation between high-voltage circuits.

[0035] A current sensor is a measuring device that converts the current value in a conductor into a standardized electrical signal. Its core function is to achieve isolated detection, accurate quantification, and real-time monitoring of current.

[0036] Hall effect sensing element: A sensing element that works based on the Hall effect principle. In the high-voltage connector scenario of this application, it is mainly used to detect the current magnitude of the connection terminal 200 in a non-contact manner.

[0037] Fluxgate type detection element: A magnetic sensing element that operates based on the fluxgate effect. In the application scenario of this application, it is mainly used for high-precision non-contact measurement of the current magnitude of the connection terminal 200.

[0038] Figure 1 This is a schematic diagram of the high-voltage connector provided in this application. Figure 2 The provisions provided for this application Figure 1 A sectional view along direction A, such as Figure 2 As shown, the specific application scenarios of this application are mainly concentrated in large-scale energy storage systems and high-power electrical equipment. As a core component of power output, the high-voltage connector needs to achieve a safe and reliable electrical connection under high voltage and high current conditions. Simultaneously, the energy storage system needs to monitor current fluctuations and contact temperature changes during charging and discharging in real time to prevent electrical faults or fire risks caused by overcurrent or overheating.

[0039] Based on the above scenarios, the inventors discovered that in related technologies, current sensors require additional cabling to connect to the circuit and occupy system space. Current sensors are mostly independent modules, resulting in low device integration and a bloated system structure. The current signal needs to be transmitted to a remote processing unit via a wiring harness, causing signal delay and making it difficult to capture transient pulses during battery charging and discharging (such as a 30A / μs step current) in real time, thus affecting the timeliness of overcurrent protection.

[0040] In related technologies, a failure of the temperature sensor 320 requires disassembling the entire electrical compartment, leading to complex maintenance. The high-voltage connector operates in an environment with strong electromagnetic pulses, making it susceptible to electromagnetic interference over long distances.

[0041] The high-voltage connector provided in this application overcomes the above-mentioned limitations by setting the high-voltage connector to include a connection body 100, a connection terminal 200 and a detection element 300; integrating the detection and connection of the high-voltage connector into an integrated design.

[0042] A connection terminal 200 is disposed on the connection body 100, and the connection terminal 200 is used for at least electrical connection to an external circuit; a detection element 300 is disposed on the connection body 100, and the detection element 300 is used at least to acquire the status parameters of the connection terminal 200. The above configuration, based on achieving reliable connection of the high-voltage circuit, monitors the operating status of the connection terminal 200 in real time, optimizes space utilization, reduces latency, improves detection performance, and ultimately achieves the effects of improved safety, reduced failure risk, and easier operation and maintenance management.

[0043] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Figure 1 The front view of the high-voltage connector provided in the embodiment of this application is as follows: Figure 1 As shown, the high-voltage connector includes a connection body 100, a connection terminal 200, and a detection element 300. The connection terminal 200 is a conventional machined terminal or a stamped terminal. The connection terminal 200 is disposed on the connection body 100 and is used at least for electrical connection to an external circuit to achieve reliable circuit conduction.

[0051] The detection element 300 is disposed on the connection body 100, and the detection element 300 is used at least to acquire the status parameters of the connection terminal 200. This facilitates real-time monitoring of the working status of the connection terminal 200, timely warning of fault risks, and ensures the safety of the circuit connection.

[0052] The above setup, while ensuring reliable connection of the high-voltage circuit, also monitors the operating status of the connection terminal 200 in real time, thus optimizing space utilization. Simultaneously, it reduces latency, improves detection performance, and ultimately enhances safety, reduces the risk of failure, and facilitates operation and maintenance management.

[0053] Figure 2 The provisions provided for this application Figure 1 The sectional view along direction A. Please refer to... Figure 2 In one possible implementation, the connecting body 100 is provided with a sensing groove 110. The size and shape of the sensing groove 110 can be flexibly selected according to the size of the connecting terminal 200, and this application does not limit it in this regard. The sensing groove 110 is used to accommodate the detection element 300; the sensing groove 110 provides a dedicated installation space for the detection element 300, avoiding the wiring requirements of discrete sensors, significantly reducing the system layout space, realizing an integrated structural design, and simplifying the overall assembly process of the high-voltage connector.

[0054] like Figure 2 As shown, the connection terminal 200 passes through the bottom surface of the sensing groove 110, and at least a portion of the connection terminal 200 extends out of the opening of the sensing groove 110 for fixing to the connection body 100. The core function of the design of setting the sensing groove 110 in the connection body 100 and coordinating the layout of the connection terminal 200 is to optimize the installation positioning and monitoring accuracy of the detection element 300, while also taking into account the compact structure and operational reliability of the high-voltage connector.

[0055] The integrated design of the detection component 300 and the high-voltage connector avoids the need for separate disassembly and assembly of discrete sensors, reducing maintenance complexity and time costs.

[0056] Unlike related technologies that connect the current sensing element 310 in series in the circuit and set it independently, in one possible implementation, this application sets the current sensing element 310 as a Hall-type sensing element or a fluxgate-type sensing element. By setting the current sensing element 310 as a Hall-type sensing element or a fluxgate-type sensing element, the core function is to achieve non-contact and accurate measurement of the current of the high-voltage connector, adapt to the safety monitoring requirements of high-current scenarios, and at the same time take into account the detection stability and structural compatibility.

[0057] In one possible implementation, the fluxgate detector uses a CC6836 chip, with a U-shaped magnetic core fitted onto the conductive portion of the connection terminal 200 to form a magnetically coupled detection circuit. A square wave excitation signal with a frequency of 12kHz is applied to the excitation coil of the fluxgate detector to drive the U-shaped magnetic core to generate an alternating magnetic field. The detection signal induced by the detection coil is transmitted to the signal processing terminal of the CC6836 chip, and is amplified, filtered, and linearly corrected by the chip's built-in high-voltage slew rate operational amplifier (slew rate parameter of 10V / μs).

[0058] With the above configuration, the fluxgate detector of this embodiment can achieve a detection accuracy of ±0.5% for the status parameters of the connection terminal 200, and the temperature drift coefficient is as low as 0.2% in the entire operating temperature range, which effectively ensures the accuracy and stability of the detection data and meets the high-precision monitoring requirements of high-voltage connectors.

[0059] To further enhance the magnetic field focusing effect and improve detection sensitivity and response speed, the surface of the connecting terminal 200 is coated with a high-frequency magnetic material, preferably an iron-nickel alloy. This high-frequency magnetic material coating can concentrate the dispersed magnetic field generated by the current when the connecting terminal 200 conducts current, so that the U-shaped magnetic core can sense changes in the magnetic field more efficiently, thereby optimizing the signal-to-noise ratio of the detection signal.

[0060] In one possible implementation, the Hall-type detection device is selected from the TMCS11235 Hall current detection chip. The specific assembly method is as follows: the connection terminal 200 of the high-voltage connector passes through the central aperture of the TMCS11235 chip along the axial direction, so that the connection terminal 200 is in the magnetic field sensing area of ​​the chip, so as to directly sense the magnetic field change generated when the connection terminal 200 conducts current.

[0061] To optimize the magnetic field uniformity of the chip sensing area and improve the linearity and consistency of the detection signal, the connection terminal 200 adopts a flat rectangular cross-section structure instead of the conventional circular cross-section. The flat rectangular structure allows the magnetic field generated when the connection terminal 200 conducts current to be distributed more evenly within the chip sensing window, avoiding detection deviations caused by local concentration of the magnetic field.

[0062] The TMCS11235 chip features a low temperature drift of 50ppm / °C, effectively offsetting interference caused by ambient temperature fluctuations and ensuring detection stability across the entire temperature range. Furthermore, without the need for additional signal conditioning circuitry, the chip directly outputs an isolation voltage signal linearly related to the 200V current at the connection terminal, achieving electrical isolation between the detection signal and the high-voltage circuit, thus enhancing signal transmission safety and anti-interference capabilities.

[0063] Based on the integrated design of the above fluxgate or Hall effect detector and high-voltage connector, this solution has the following significant advantages compared with the traditional discrete sensor monitoring solution: it eliminates discrete sensors and independent wiring harnesses, integrates the detector 300 inside the high-voltage connector, increases the wiring density of the energy storage cabinet by 40%, and is suitable for containerized energy storage systems with limited space.

[0064] like Figure 1 As shown, the current detection element 310 is provided with a detection port, and the connection terminal 200 passes through the detection port; the current detection element 310 does not contact the connection terminal 200, and the current detection element 310 can obtain the current of the connection terminal 200 based on the magnetic effect of the connection terminal 200.

[0065] There is no need for direct contact with the high-voltage conductive part of the connection terminal 200. The connection terminal 200 also serves as the primary conductor of the current detection device 310. Unlike existing current detection devices, it eliminates the need for additional sampling cables. Based on the principle of electromagnetic induction, it detects the magnitude of the current by sensing the magnetic field generated when the connection terminal 200 is energized.

[0066] Hall effect and fluxgate type detectors are generally small in size and can be directly embedded in the sensing slot 110. The connecting terminal 200 also serves as a primary conductor. The current detection device 310 calculates the current magnitude of the connecting terminal 200 by detecting the magnetic field strength of the connecting terminal 200, achieving a high degree of integration. At the same time, the use of electromagnetic induction avoids the risk of insulation breakdown caused by connecting the detection device 300 to a high-voltage circuit, thus meeting the safety requirements of high-voltage connectors.

[0067] In one possible implementation, the distance between the current sensing element 310 and the connection terminal 200 is less than or equal to 1 mm in the bottom surface of the sensing slot 110; furthermore, the magnetic field induction efficiency is optimized by the tight coupling between the magnetic core of the current sensing element 310 and the connection terminal 200, thereby improving the current detection accuracy and reducing the signal attenuation problem caused by excessive spacing.

[0068] In one possible implementation, the inner wall of the sensing slot 110 is provided with a shielding layer. Optionally, the shielding layer material is copper foil, which can effectively block the influence of external electromagnetic interference on the signal of the internal detection element 300 of the sensing slot 110, ensuring measurement accuracy. At the same time, copper foil has good ductility and adhesion, and can be tightly attached to the inner wall surface of the sensing slot 110, adapting to the structural shape of the sensing slot 110 and improving the installation adaptability and shielding stability of the shielding layer.

[0069] In one possible implementation, a fixing adhesive is provided on the bottom surface of the sensing groove 110. Optionally, the current sensing element 310 is fixed to the center position of the sensing groove 110 by epoxy resin potting. The epoxy resin potting process not only securely limits the current sensing element 310, preventing displacement due to vibration during operation, but also provides protection for the current sensing element 310 due to the excellent insulation and corrosion resistance of epoxy resin, ensuring the stability and accuracy of current detection.

[0070] In one possible implementation, the detection element 300 includes a temperature sensor 320, which is used at least to acquire the temperature of the connection terminal 200. This avoids signal delay, monitors the heating status of the connection terminal 200 in real time, provides early warning of thermal failure risks, and ensures the safe and stable operation of the high-voltage circuit.

[0071] Optionally, multiple temperature sensors 320 are used, and these multiple temperature sensors 320 are disposed on the side wall of the sensing slot 110. This enables full-range and accurate detection of the temperature of the connection terminal 200, eliminates temperature measurement blind spots, and improves the reliability and timeliness of thermal fault early warning.

[0072] Optional, such as Figure 1 As shown, the temperature sensor 320 array consists of two thermistors arranged in a 180° ring on the inner wall of the sensing groove 110, and the contact of the thermistor is less than or equal to 2 mm from the mating surface of the connection terminal 200.

[0073] In one possible implementation, an over-temperature alarm is triggered when any temperature sensor 320 detects a temperature greater than 105°C or when the temperature difference between adjacent temperature sensors 320 is greater than 15°C.

[0074] This embodiment discloses an integrated multi-parameter monitoring device, such as... Figure 1 As shown, a signal processing integrated circuit 400 is embedded in the shielding layer. The signal processing integrated circuit 400 is electrically connected to the detection device 300 through a gold wire bonding process. The shielding layer isolates external electromagnetic interference, while the gold wire bonding ensures the stability of signal transmission.

[0075] The signal processing integrated circuit 400 has a built-in current-temperature fusion unit. This unit performs fast Fourier transform analysis on the current signal collected by the detection device 300, extracts the frequency domain features of the current signal, and simultaneously retrieves the temperature data collected by the temperature sensor 320. The fusion calculation generates the Load Health Index (LHI).

[0076] The signal processing integrated circuit 400 is equipped with a CANFD (Controller Area Network with Flexible Data-Rate) digital output interface. The baud rate of the arbitration segment of this interface is set to 1 Mbps and the baud rate of the data segment is set to 5 Mbps. Through this interface, current value, temperature data and LHI three types of parameters are output to meet the requirements of high-speed data transmission.

[0077] Secondly, this application provides an electrical device including a high-voltage connector in any of the above possible embodiments; the aim is to improve the safety, reliability and intelligence level of the high-voltage power supply system of the device, while reducing operation and maintenance costs and adapting to complex working conditions.

[0078] The high-voltage connector and electrical equipment provided in this application embodiment have a detection element 300 that is closely coupled to the connection terminal 200, reducing the current detection delay to 0.3 microseconds and increasing the overcurrent protection response speed by 6 times; the temperature sampling point is only 2 mm away from the connection terminal 200, which greatly improves the overall performance of the high-voltage connector.

[0079] The integrated design of the detection component 300 and the high-voltage connector allows for seamless replacement, reducing fault handling time by 50% and simplifying on-site maintenance. Based on current and temperature parameters, the accuracy of potential fault prediction exceeds 90%, resulting in a 50% reduction in overall maintenance costs and enabling intelligent operation and maintenance.

[0080] In summary, this solution achieves comprehensive optimization of space, performance, operation and maintenance, and intelligent management through integrated design, meeting the high reliability and high density application requirements of containerized energy storage systems.

[0081] The high-voltage connector and electrical equipment provided in this application achieve a stable electrical connection between the two by setting the connection terminal 200 on the connection body 100 and using the connection terminal 200 for at least electrical connection to an external circuit, thus meeting the power supply requirements of high-voltage equipment. By setting the connection body 100 as a carrier and integrating the detection component 300, an integrated design of connection and monitoring is achieved, avoiding signal delay, complex maintenance, and bloated system structure.
