Description

Technical Field

[0001] This invention relates to the field of new energy battery pack technology, specifically to a high-current battery pack panel that integrates a connector, an MSD fuse, and a temperature sensor. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the reliability, safety, and manufacturing cost of the electrical connection system of the power battery pack, as a core energy storage component, are receiving increasing attention. The battery pack needs to perform multiple electrical functions, including high-current charging and discharging, high-voltage circuit safety protection, battery heating management, signal acquisition and transmission, and temperature monitoring. These functions involve the coordinated operation of multiple electrical components.

[0003] Currently, new energy passenger vehicles and energy storage battery packs generally adopt a separate, independent component solution: through-hole connectors, heating connectors, signal connectors, MSD (Manual Service Disconnect) fuses, and temperature sensors are all independently purchased components, each with its own independent plastic housing, sealing ring, mounting bracket, and locking screws. Specifically, each component is positioned by drilling holes in the sheet metal or plastic panel of the battery pack; the inside of the components is connected by segmented copper busbars and bundled high-voltage / low-voltage wiring harnesses; the temperature sensor is individually attached to the surface of the cell or copper busbar and connected to the battery management system through an independent wiring harness; each external interface is exposed by a separate hole, and each connector is secured with 2 to 4 screws.

[0004] During high-current charging and discharging, the current is conducted through multiple busbars, independent high-voltage connectors, and MSD segmented conduction; the heating circuit is driven by a separate wire harness for thermal management; the signal and temperature measurement wire harnesses are collected separately; multiple independent sealing rings are used to achieve waterproof sealing of each device, and segmented conductors are used to complete the current carrying path; the production line relies on manual or equipment to screw each component together and individually connect each wire harness to complete the assembly.

[0005] However, the aforementioned existing technical solutions have the following significant defects and shortcomings:

[0006] First, the assembly process is complex, the production line cycle time is long, and the cost of automation upgrades is high. Many types of components need to be individually positioned, screwed, wire harnesses plugged in, and glued for sealing; multiple automated production lines require multiple sets of tightening and plugging tooling, resulting in high equipment investment costs, slow ramp-up of vehicle factory production capacity, and seriously affecting the mass production efficiency of vehicle models.

[0007] Secondly, the variety of materials is complex, resulting in high supply chain and warehousing costs. Connectors, fuses, sensors, brackets, seals, and fasteners are supplied by multiple vendors, and the types of materials are numerous. The costs of mold development, procurement, warehousing, sorting, and incoming material inspection are cumulative, leading to a significant increase in the cost per vehicle. Simultaneous management of multiple vendors can easily lead to problems such as delivery delays and production line stoppages due to incorrect materials.

[0008] Third, excessive connection points can easily lead to excessive heat generation and temperature rise due to high current. Multiple overlapping layers between busbars, terminals, and connectors result in numerous contact points. Under high-current fast charging conditions, increased contact resistance can cause excessive temperature rise, posing a risk of thermal runaway and severely impacting the safety and lifespan of the battery pack.

[0009] Fourth, temperature monitoring is inadequate, and the ability to warn of thermal runaway is insufficient. In existing solutions, temperature sensors are individually attached to the surface of the battery cell or copper busbar and connected to the BMS via independent wiring. This not only increases the complexity of the wiring harness but also lacks effective real-time monitoring methods for temperature rise at high-current terminals and copper busbar connections, making it difficult to detect potential overheating hazards in a timely manner.

[0010] Fifth, product consistency and reliability are difficult to guarantee. Dispersed components and independent sealing structures result in poor consistency in waterproof and insulation performance; multi-point fastening connections are prone to failures such as loose connections and sparking under long-term vibration and temperature cycling conditions, affecting the overall vehicle reliability.

[0011] In view of the shortcomings of the existing technology, there is an urgent need for a new type of high-current battery pack panel solution that can integrate multiple electrical functions, reduce the number of parts and assembly processes, reduce contact resistance and temperature rise, and improve temperature monitoring capabilities. Summary of the Invention

[0012] To address the aforementioned problems, this invention provides a high-current battery pack panel that integrates a connector, an MSD fuse, and a temperature sensor. This addresses the technical issues in existing battery pack electrical systems, such as the dispersed and independent nature of functional components, numerous assembly processes, excessive connection nodes leading to severe heat generation, and inadequate temperature monitoring.

[0013] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a high-current battery pack panel integrating a connector, an MSD fuse, and a temperature sensor, comprising: a panel body and a heating connector, a signal connector, a wire connector, an MSD fuse, and a temperature sensor disposed on the panel body;

[0014] The panel body has an inner side and an outer side. The heating connector, signal connector, and wire connector all pass through the panel body. The MSD fuse is disposed on the panel body and electrically connected to the wire connector. The temperature sensor is disposed on the panel body for detecting temperature.

[0015] A further improvement is that the heating connector includes a male positive terminal and a male negative terminal disposed on the inner side of the panel body, and a male plug positive terminal and a male plug negative terminal disposed on the outer side of the panel body. The male positive terminal and the male negative terminal constitute the male terminal of the heating connector, and the male plug positive terminal and the male plug negative terminal constitute the male plug of the heating connector. The male terminal and the male plug of the heating connector are electrically connected accordingly.

[0016] A further improvement is that the signal connector includes a first signal connector and a second signal connector disposed on the outer side of the panel body, and a third signal connector and a fourth signal connector disposed on the inner side of the panel body. The first signal connector, the second signal connector, and the third signal connector and the fourth signal connector pass through the panel body through through-board pins to achieve signal transmission.

[0017] A further improvement is that: there are multiple through-board pins, and each through-board pin is first encapsulated and injection molded to form a signal pin module, and the signal pin module is detachably installed on the panel body.

[0018] A further improvement is that it also includes a positive copper busbar and a negative copper busbar disposed on the panel body. The wire connector at one end is electrically connected to one end of the MSD fuse through the positive copper busbar. The other end of the MSD fuse is used to electrically connect to the battery cell or charged body of the battery pack. The battery cell or charged body of the battery pack is electrically connected to the wire connector at the other end through the negative copper busbar to form a charging and discharging circuit.

[0019] A further improvement is that the positive copper busbar is a single, integrated copper busbar, with one end connected to the terminal block of the wire connector and the other end connected to the terminal block of the MSD fuse.

[0020] A further improvement is that the temperature sensor is disposed on the surface of the positive electrode copper busbar and the surface of the negative electrode copper busbar, for real-time monitoring of the temperature of the positive electrode copper busbar and the negative electrode copper busbar.

[0021] A further improvement is that the cable connector has a cable hole for external cables to pass through, and after the external cable passes through the cable hole, it is fixedly connected to the positive or negative copper busbar by a crimp terminal.

[0022] A further improvement is that the positive and negative terminals of the heating connector plugs independently penetrate the panel body, used to introduce external power into the heating load inside the battery pack, or for series connection between adjacent battery packs.

[0023] A further improvement is that it also includes a sealing cap, which is placed over the wire hole of the wire connector to provide protection and insulation.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention integrates the heating connector, signal connector, wire guide connector, MSD fuse, and temperature sensor onto a single panel body, significantly reducing the number of individual components, simplifying the bill of materials, and lowering costs in mold development, procurement, warehousing, and incoming material inspection. Simultaneously, it reduces the use of auxiliary materials such as fasteners, seals, and brackets, resulting in a significant decrease in per-vehicle cost.

[0026] The integrated panel design simplifies the complex assembly process, which previously required multiple positioning, screwing, and wiring harness insertion, into a single installation, significantly shortening the production line cycle time. Reduced production line automation costs and faster capacity ramp-up facilitate rapid iteration and mass production of vehicle platforms.

[0027] This invention employs a single, integrated positive copper busbar to connect the terminals of the connector to the MSD fuse, reducing the number of contact points caused by the overlapping of multiple busbars in traditional solutions. The reduced contact resistance effectively decreases heat generation under high-current fast charging conditions, effectively controlling temperature rise, lowering the risk of thermal runaway, and improving the safety and lifespan of the battery pack.

[0028] This invention directly mounts temperature sensors on the surfaces of the positive and negative copper busbars, enabling real-time monitoring of temperature changes in high-current circuits. Compared to traditional solutions that attach temperature sensors separately to the surface of the battery cell or copper busbar and connect them to the BMS via independent wiring harnesses, this integrated temperature monitoring solution is more reliable, responds faster, and can promptly detect abnormal temperature rises and trigger protection mechanisms, effectively preventing thermal runaway accidents.

[0029] The integrated design ensures more stable relative positions and connections between components, reducing cumulative errors caused by scattered installations. The overall structure is highly rigid, with fewer fasteners, offering excellent shock resistance and temperature variation resistance, making it less prone to malfunctions such as loose connections and arcing over long-term use. The integrated sealing structure enhances waterproof and insulation performance, resulting in higher product consistency.

[0030] This invention employs a method of first encapsulating the through-board pins with glue and injection molding to form a signal pin module, and then detachably installing the module onto the panel body. This avoids the complex process of directly injection molding the through-board pins to the panel body as a single unit, reducing the design difficulty and manufacturing cost of the panel mold. At the same time, the detachable design of the signal pin module facilitates maintenance and replacement, improving the maintainability of the product. Attached Figure Description

Detailed Implementation

[0036] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0037] according to Figure 1-4 As shown, this embodiment proposes a solution:

[0038] The present invention provides a high-current battery pack panel integrating a connector, an MSD fuse and a temperature sensor, which mainly includes a panel body 100 and a heating connector, a signal connector, a wire connector 5, an MSD fuse 13 and a temperature sensor 12 integrated on the panel body 100.

[0039] The panel body 100 is fixed to the battery pack housing or cover, serving as an interface between the internal electrical system and the external electrical system of the battery pack.

[0040] Multiple through holes are provided on the panel body 100 for mounting various connectors. Heating connectors, signal connectors, and wire guide connectors 5 all penetrate the panel body 100, with both ends of each connector located on the inner and outer sides of the panel body 100, respectively. An MSD fuse 13 is located on the outer side of the panel body 100 and is electrically connected to the wire guide connector 5. A temperature sensor 12 is located on the inner side of the panel body 100 for detecting the real-time temperature of critical components.

[0041] The heating connector includes a male positive terminal 7 and a male negative terminal 8 disposed inside the panel body 100, and a heating connector plug positive terminal 1 and a heating connector plug negative terminal 2 disposed outside the panel body 100.

[0042] The male positive terminal 7 and the male negative terminal 8 of the heating connector constitute the male terminal of the heating connector. Both are fixed to the inner surface of the panel body 100 and electrically connected to corresponding terminals on the outer surface through the panel body 100. The positive terminal 1 and the negative terminal 2 of the heating connector plug constitute the heating connector plug, both fixed to the outer surface of the panel body 100. The male terminal and the heating connector plug are electrically connected through a conductor penetrating the panel body 100.

[0043] The heating connector is used to realize the heating function of the battery pack: the external heating power is introduced into the panel body 100 through the positive terminal 1 and negative terminal 2 of the heating connector plug, and output to the heating load inside the battery pack, such as the heating film or PTC heater, through the positive terminal 7 and negative terminal 8 of the heating connector male terminal, thereby heating the battery pack in a low-temperature environment and ensuring the charging and discharging performance of the battery at low temperatures.

[0044] In another application scenario, the heating connector is used to achieve series connection between adjacent battery packs: the positive terminal 1 and the negative terminal 2 of the heating connector plug are connected to the corresponding terminals of adjacent battery packs via external wiring harnesses, thereby achieving voltage superposition between multiple battery packs to meet the power requirements of higher voltage levels. This dual-function design makes the heating connector of the present invention more widely applicable.

[0045] The signal connectors include a first signal connector 3 and a second signal connector 4 disposed on the outside of the panel body 100, and a third signal connector 10 and a fourth signal connector 11 disposed on the inside of the panel body 100.

[0046] The first signal connector 3, the second signal connector 4, the third signal connector 10, and the fourth signal connector 11 transmit signals through the panel body 100 via through-hole pins 9. Specifically, the through-hole pins 9 are multiple independent conductive metal pins that penetrate perpendicularly through the thickness direction of the panel body 100. The outer end of the through-hole pins 9 makes electrical contact with the terminals of the first signal connector 3 and the second signal connector 4, and the inner end of the through-hole pins 9 makes electrical contact with the terminals of the third signal connector 10 and the fourth signal connector 11.

[0047] In practical applications, the first signal connector 3 and the second signal connector 4 connect to the vehicle wiring harness to receive control commands from the vehicle control unit (VCU) or to provide battery pack status information to the VCU. The third signal connector 10 and the fourth signal connector 11 connect to the BMS wiring harness inside the battery pack to collect signals such as cell voltage and temperature or to transmit control commands to the BMS. Through the "through-board" conduction of the through-board pin 9, external and internal signals can be reliably transmitted while ensuring the airtightness of the panel body 100.

[0048] There are multiple through-board pins 9. Each through-board pin 9 is first encapsulated and injection molded to form a signal pin module. This signal pin module is then installed on the panel body 100 by means of snap-fit ​​or screws. This design has the following significant advantages: First, it avoids directly injection molding the through-board pins to the panel body 100 as a single piece, greatly reducing the mold design difficulty and manufacturing cost of the panel body 100; Second, the signal pin module is detachable, so when the through-board pin is damaged, only the module needs to be replaced instead of the entire panel, improving maintainability; Third, the modular design facilitates production line assembly and quality control.

[0049] The high-current charging and discharging circuit of the present invention includes a wire connector 5, a positive copper busbar 16, an MSD fuse 13, and a negative copper busbar 17.

[0050] The cable connector 5 has a cable hole for the external cable 18 to pass through. The external cable 18 passes through the cable hole from the outside of the panel body 100 and enters the inside of the panel body 100. The end of the external cable 18 is crimped to form a terminal 14. The terminal 14 is fixedly connected to one end of the positive copper busbar 16 by a bolt 15, realizing a reliable electrical connection between the external cable and the positive copper busbar 16.

[0051] The positive electrode copper busbar 16 is a single, integrated copper busbar. One end of the positive electrode copper busbar 16 has a mounting hole for connection to the terminal block 14, and the other end has a mounting hole for connection to the terminal block of the MSD fuse 13. The middle section of the positive electrode copper busbar 16 is formed from a single piece of copper material without any overlap or welding joints. This design effectively reduces the contact points caused by the overlap of multiple busbar sections in traditional solutions, significantly reducing contact resistance, thereby reducing heat generation under high-current fast charging conditions and effectively controlling temperature rise.

[0052] One end of the MSD fuse 13 is electrically connected to the positive copper busbar 16, and the other end of the MSD fuse 13 is used to electrically connect to the positive output terminal of the battery cell or charged component of the battery pack, such as the battery module. The MSD fuse 13 integrates the dual functions of a manual maintenance switch and a fuse: on the one hand, maintenance personnel can manually pull out the MSD fuse 13 to disconnect the high-voltage circuit and ensure maintenance safety; on the other hand, when an abnormally large current such as a short circuit occurs in the circuit, the fuse element inside the MSD fuse 13 melts, automatically cutting off the high-voltage circuit and playing an overcurrent protection role.

[0053] The battery cells or charged components of the battery pack are electrically connected to the other end of the wire connector 5 via the negative copper busbar 17. Specifically, the negative output terminal of the battery cell is connected to one end of the negative copper busbar 17 via a wire or busbar, and the other end of the negative copper busbar 17 is connected to the cable of another wire connector 5 via a terminal block and a bolt. Thus, the external cable 18—wire connector 5—positive copper busbar 16—MSD fuse 13—battery cell—negative copper busbar 17—another wire connector 5—another external cable 18 forms a complete charging and discharging circuit.

[0054] During fast charging, a large current flows through the aforementioned circuit. Because the positive copper busbar 16 uses a one-piece structure, it reduces contact points, resulting in low contact resistance and low heat generation, effectively carrying a large current without causing overheating. Simultaneously, the MSD fuse 13 provides reliable overcurrent protection and maintenance safety isolation for the circuit.

[0055] Temperature sensor 12 is disposed on the surface of positive copper busbar 16 and negative copper busbar 17. Temperature sensor 12 is attached to the surface of copper busbar by thermally conductive adhesive or mounting bracket, and is used to monitor the temperature of positive copper busbar 16 and negative copper busbar 17 in real time.

[0056] The signal line of temperature sensor 12 is connected to the third signal connector 10 or the fourth signal connector 11, and transmitted to the battery management system (BMS) via the through-board pin 9 and the first signal connector 3 or the second signal connector 4. The BMS judges the temperature rise of the copper busbar in real time based on the received temperature data: when the temperature exceeds the preset threshold, the BMS issues an alarm signal or actively reduces the charging and discharging power, and disconnects the high-voltage circuit if necessary, thereby avoiding thermal runaway accidents caused by excessive temperature rise.

[0057] Compared with the traditional approach of attaching the temperature sensor separately to the surface of the battery cell or copper busbar and connecting it to the BMS through a separate wiring harness, the temperature sensor 12 of the present invention is integrated on the panel body 100. The signal is transmitted through an integrated signal connector, eliminating the need for additional wiring. The structure is more compact and reliable, with a faster response speed, and can detect abnormal temperature rise more promptly.

[0058] The invention also includes a sealing cover 6, which is disposed over the wire hole of the wire connector 5 for protection and insulation. Specifically, when an external cable passes through the wire hole of the wire connector 5, the sealing cover 6 is fastened to the outside or inside of the wire hole, and a waterproof seal is achieved through a sealing ring to prevent moisture, dust and other foreign objects from entering the battery pack through the wire hole.

[0059] During assembly of the high-current battery pack panel of the present invention, firstly, the through-board pins 9 are injection molded to form signal pin modules, and then the signal pin modules are installed on the panel body 100; subsequently, the male positive terminal 7 of the heating connector, the male negative terminal 8 of the heating connector, the third signal connector 10, and the fourth signal connector 11 are installed on the inner side of the panel body 100, and the positive terminal 1 of the heating connector plug, the negative terminal 2 of the heating connector plug, the first signal connector 3, the second signal connector 4, and the wire connector 5 are installed on the outer side of the panel body 100; the positive copper busbar 16 and the negative copper busbar 17 are fixed on the panel body 100, and the MSD fuse 13 is installed on the panel body 100 and connected to the positive copper busbar 16; the temperature sensor 12 is attached to the surface of the positive copper busbar 16 and the negative copper busbar 17; finally, the sealing cover 6 is installed.

[0060] During operation, high-current charging and discharging form a circuit through connector 5, positive copper busbar 16, MSD fuse 13, battery pack cells, negative copper busbar 17, and another connector 5. Temperature sensor 12 monitors the temperature of positive and negative copper busbars 16 and transmits the temperature signal to the BMS via a signal connector. When heating is required, external power is introduced into the heating load inside the battery pack through the heating connector. When maintenance is needed, the high-voltage circuit can be safely disconnected by manually pulling out MSD fuse 13.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
