Abstract
Description
Technical Field
[0001] This invention relates to the field of battery management technology, specifically to a battery pack electronic control integrated unit. Background Technology
[0002] With the rapid development of lithium battery systems, traditional electronic control structures mostly rely on fixed layouts inside and outside the battery pack. While this design approach offers some system integration initially, it has significant shortcomings in terms of space utilization efficiency. Especially when dealing with diverse electronic control modules, the limited installation methods of components and the obstructed stacking space often necessitate reserving extra redundant space for the electronic control system, leading to an increase in the overall size of the battery pack. Furthermore, once the structure is determined, subsequent upgrades or configuration adjustments become particularly passive, making it difficult to flexibly adapt to the development needs of different platforms.
[0003] Currently, different battery pack products have significantly different structural and functional requirements for their electronic control systems, lacking a unified standard template. This "non-template" phenomenon often requires designers to redevelop the electronic control structure for each project, resulting in repetitive work and potential design deviations due to version inconsistencies or interface differences. Furthermore, the lack of standardized component types and significant size variations, coupled with the difficulty in using universal molds and fixtures, necessitates greater investment of process resources and manpower during processing and assembly, further increasing manufacturing costs and extending delivery cycles.
[0004] In actual production and subsequent maintenance, the wiring harness layout under traditional structures is extremely complex, increasing assembly workload and making disassembly and repair equally time-consuming and labor-intensive. Due to the weak commonality between projects, maintenance engineers often face the dilemma of "one solution per project," posing a significant challenge to after-sales service. Simultaneously, the dispersed sizes and varied shapes of component control boards make large-scale, standardized production difficult, creating significant bottlenecks for companies when expanding production or delivering in batches. These problems have become key obstacles to the industrialization and efficient delivery of current lithium battery control systems. Therefore, a battery pack control integration unit is proposed to address these issues. Summary of the Invention

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Please see the appendix Figure 1 -Appendix Figure 6This invention provides a battery pack electronic control integrated unit, including a BDU housing carrier 2. A BDU housing cover 1 is disposed on the upper side of the BDU housing carrier 2. Both the BDU housing cover 1 and the BDU housing carrier 2 are made of PC+10%GF. The BDU housing cover 1 protects the internal components and prevents electrical components from direct contact with the outside. The BDU housing carrier 2 has electrical components and a PCB circuit board 3 arranged vertically in layers. A bottom insulating plate 4 is disposed at the bottom of the BDU housing carrier 2. The bottom insulating plate 4 is made of epoxy resin board FR4 and is used to protect the PCB board from direct contact with the housing. A PCB circuit board 3 is disposed between the BDU housing carrier 2 and the bottom insulating plate 4. This structure allows the electrical control part to be integrated within the housing. The compact design achieves multifunctional integration while effectively isolating electrical and structural components, enhancing overall safety and stability. Relays 3001 are positioned at the top four corners of the PCB board 3. Relays 3001 are divided into pre-charge, self-locking, and heating relays. This placement helps ensure signal independence and minimize electrical interference between relays 3001. The pre-charge relay provides current-limiting charging during initial battery connection to prevent damage from sudden current surges. The self-locking relay maintains the main circuit closed during battery operation to ensure continuous and stable operation. The heating relay activates the heating circuit in low-temperature environments to maintain the battery within its optimal operating temperature range, thereby protecting the battery. For performance and lifespan, the top of PCB circuit board 3 is equipped with a BDU communication interface 3003 and a blade fuse 3006. The BDU communication interface 3003 is used to realize data interaction between the battery management system and the vehicle or host computer, enabling efficient transmission of control commands and status monitoring. The blade fuse 3006, as an overcurrent protection device, quickly melts and cuts off the power supply when an abnormal current occurs in the system, preventing the fault from escalating. Inside the BDU communication interface 3003 and the blade fuse 3006, relay interface 1 3002 and relay interface 2 3008 are respectively provided. These two sets of interfaces provide independent control channels and working power paths for relay 3001, enabling it to start and stop independently according to different control logic, improving circuit response. To ensure flexibility and safety, the PCB circuit board 3 has an auxiliary power and heating function external interface 3004 and a resistor interface 3007 located diagonally opposite each other. The auxiliary power and heating function external interface 3004 is used to output control signals to the heating element or external auxiliary power supply, realizing the expandability of external power supply and heating functions. The resistor interface 3007 connects to the current-limiting resistor in the circuit, which can be used for energy buffering or energy release during the discharge process to stabilize the system's operating state. A shunt interface 3005 is located on the side closer to the auxiliary power and heating function external interface 3004, which is used to connect a current shunt. A monitoring element 5 is located on the side farther from the shunt interface 3005, which integrates multiple sensors such as temperature, voltage, and current.The system collects battery pack operating parameters in real time and uploads them to the main control system for intelligent analysis, thereby achieving real-time monitoring and early warning of abnormal battery operation, effectively improving system safety and intelligence.
[0040] Monitoring Entity 5 includes:
[0041] Temperature sensors are used to monitor the temperature of the battery pack. By sensing the temperature inside the battery pack and the surrounding environment in real time, it is possible to determine whether the battery is in an overheated or overcooled state, thereby providing thermal management basis for the central control system to achieve precise control of heating, heat dissipation or power limiting measures, and avoid safety hazards such as battery performance degradation or thermal runaway caused by abnormal temperature.
[0042] Voltage sensors are used to measure the voltage level of each battery cell in the battery pack. By collecting the independent voltage of multiple cells, inconsistencies between cells can be identified, and abnormal states such as overvoltage and undervoltage can be detected in time. This helps the central control system to adjust the charging and discharging strategy or issue alarm signals to ensure the balanced operation and lifespan of the entire battery pack.
[0043] The current sensor is used to monitor the charging and discharging current of the battery. It can accurately collect instantaneous and cumulative current to help determine the battery's operating status and load conditions. At the same time, it can be used in conjunction with voltage data to estimate the state of charge (SOC), providing a basis for vehicle energy management and timely protection against overcurrent.
[0044] The monitoring unit 5 transmits the collected data to the central control system. After receiving the multi-dimensional data from various sensors, the central control system can perform real-time analysis of the battery status, fault judgment, and strategy decision-making based on preset algorithms, thereby realizing dynamic management, intelligent control, and safety protection of the entire battery pack and improving the reliability and efficiency of system operation.
[0045] Please see the appendix Figure 7 -Appendix Figure 8The inner bottom wall of the BDU housing carrier 2 has two equidistant relay recesses 2007. The inner sides of both relay recesses 2007 are connected to charge / discharge relays 2002 via bolts, providing a stable fixing position for the charge / discharge relays 2002. The bolt connection ensures stable operation of the relays 3001 during operation, preventing loosening due to vibration or external forces, thus improving the reliability and safety of the battery management unit (BDU). The inner side wall of the BDU housing carrier 2 is provided with a resistor placement plate 2008, which effectively fixes the resistor 2004, preventing displacement of the resistor 2004 due to vibration or current changes during operation. Misalignment or poor contact ensures more stable and reliable energy regulation in the battery circuit. The top of the resistor placement plate 2008 is connected to the resistor 2004 by bolts. The positive terminals of the two charge / discharge relays 2002 are connected to the L-shaped hard copper busbar 20010 by bolts. The L-shaped hard copper busbar 20010 provides a stable current path, ensuring smooth current transmission during charging and discharging, reducing losses in current conduction, and optimizing the efficiency of the battery management system. The shorter end of the L-shaped hard copper busbar 20010 is connected to the high-current fuse 2001 by bolts and is located on the BDU housing carrier 2. At the top, the circuit is promptly cut off when the current is too high, preventing battery damage or fire due to overcurrent. The negative terminals of both charge / discharge relays 2002 are bolted to Z-shaped connecting pieces 20011, providing a low-impedance path for current transmission and reducing energy loss. Two support blocks 2006 are equidistantly arranged on the inner wall of the BDU housing carrier 2. These support blocks 2006 support the Z-shaped connecting pieces 20011, preventing them from loosening or shifting due to vibration or current surges during operation, thus enhancing the stability of the electrical connection. Two screws 2009 are equidistantly arranged on the side away from the resistor placement plate 2008, with a [missing information - likely a design feature] between the screws 2009. The design includes a shunt 2003 and a screw 2009 for fixing and supporting the shunt 2003, ensuring the stability and accuracy of the shunt 2003 during current distribution. The outer four corners of the BDU housing cover 1 are provided with male buckles 1001, and the inner four corners of the BDU housing carrier 2 are provided with female buckles 2005. The male buckles 1001 engage with the corresponding female buckles 2005. The design of the male buckles 1001 and female buckles 2005 provides a convenient locking mechanism, which allows the BDU housing cover 1 and the BDU housing carrier 2 to be firmly fastened together. This not only facilitates disassembly and installation but also ensures that the housing will not loosen due to vibration or external force during use, ensuring the safe operation of the battery pack.
[0046] The charge / discharge relay 2002 connects to relay interface 3002 and relay interface 3008 on the PCB circuit board 3 via a plug-in interface. This plug-in structure not only simplifies the assembly process and improves installation efficiency, but also facilitates later maintenance and replacement. Relay interface 3002 and relay interface 3008 are connected to the BDU communication interface 3003 on the PCB circuit board 3 via pre-embedded copper wires. The pre-embedded copper wires serve as internal conductive paths to achieve efficient transmission of signals and electrical energy between various components, effectively reducing safety hazards caused by exposed wiring and improving the integration and reliability of the overall wiring. Meanwhile, the BDU communication interface 3003 serves as a signal... The information interaction hub, relay 3001 is connected to auxiliary power and heating function external interface 3004 and plug-in fuse 3006 through copper wires embedded in PCB circuit board 3. Resistor interface 3007 is connected to resistor 2004 through plug-in method and to BDU communication interface 3003 through copper wires embedded in PCB circuit board 3. BDU communication interface 3003 is connected to relay 3001 and shunt interface 3005 through copper wires embedded in PCB circuit board 3. Shunt interface 3005 is connected to shunt 2003 and BDU communication interface 3003 through plug-in method and copper wires embedded in PCB circuit board 3.
[0047] Please see the appendix Figure 9 The central control system includes:
[0048] Monitoring module: It is used to transmit the data collected by monitoring device 5 to the central control system;
[0049] Analysis module: It analyzes the data collected in the central control system through the data processing unit;
[0050] The central control system includes a monitoring module. This module transmits real-time data collected by temperature, voltage, and current sensors to the central control system via a data transmission connection with the monitoring unit 5. This data provides the system with information on the battery pack's operating status, performance indicators, and potential anomalies, laying the foundation for subsequent analysis and decision-making. By continuously updating this data, the monitoring module ensures the central control system can obtain real-time operating information from the battery pack, enabling timely responses and adjustments, and ensuring stable system operation.
[0051] The central control system also includes an analysis module. This module analyzes the data collected by the central control system through a data processing unit. The data processing unit can rapidly process and analyze large amounts of real-time data, identifying the battery pack's operating trends, health status, and potential faults or anomalies. This module uses algorithmic models to calculate important indicators such as the battery's state of charge (SOC) and temperature profile. Based on the analysis results, it provides control commands to the system, such as adjusting charging and discharging strategies, starting and stopping relays, and activating heating modules. This effectively manages the battery pack's lifecycle and ensures the battery's safety, reliability, and efficient operation.
[0052] Working principle: During operation, the central control system first collects various data of the battery pack in real time through the temperature sensor, voltage sensor and current sensor in monitoring body 5. The temperature sensor monitors the temperature change of the battery pack, the voltage sensor measures the voltage level of each battery cell, and the current sensor monitors the charging and discharging current of the battery. All data is transmitted to the central control system for analysis.
[0053] The analysis module evaluates the battery status based on this data and controls the switching state of each relay 3001 according to different operating conditions. The relay 3001 is divided into pre-charge, self-locking, and heating relays. When the pre-charge relay is activated, it provides a low current pre-charge to the battery to avoid damage to the battery from instantaneous high current. The self-locking relay ensures that the battery connection will not be disconnected due to system failure during the charging process, while the heating relay is activated in a low-temperature environment to heat the battery to ensure that it operates within a suitable temperature range.
[0054] During the charging and discharging process of the battery, the high-current fuse 2001 is connected to the charge / discharge relay 2002 through the L-shaped hard copper busbar 20010. When an abnormal current occurs, the circuit is cut off in time to prevent damage to the battery. The charge / discharge relay 2002 controls the charging and discharging operation of the battery according to the instructions of the central control system to ensure that the battery operates within a safe voltage and current range. At the same time, the resistor 2004 is used to absorb excess electrical energy in the circuit and stabilize the battery's operating state.
