[0037] like Figure 1 As shown, the present application relates to an integrated intelligent power supply and distribution device and system. The integrated intelligent power supply and distribution device comprises: a lithium battery box 1;

[0038] The mounting brackets 3 are respectively arranged around the bottom of the lithium battery box 1;

[0039] A vent valve 2 is provided on the top or side of the lithium battery box 1 and is used to adjust the internal air pressure of the lithium battery box 1;

[0040] A grounding point 4 is arranged in the lithium battery housing 1 along a preset direction, and at least partially extends out of the lithium battery housing 1, and is used as a connection point for electrical grounding and eliminating potential differences in the electrical system;

[0041] The water inlet and outlet 5 is arranged near the bottom side of the lithium battery box 1 and is used to circulate the coolant and control the working temperature of the battery pack;

[0042] A plurality of connectors, arranged on the outside of the lithium battery box 1, for electrical connection between the battery management system and an external control unit or other systems; and

[0043] An intelligent power distribution box, arranged in the lithium battery box 1;

[0044] The lithium battery box 1 is integrated with the intelligent power distribution box to form an integrated intelligent power supply and distribution device. The lithium-ion battery and the intelligent power distribution box are combined into one to achieve deep integration of functions. Not only does it eliminate the traditional battery terminals, but it also saves the independent installation space of the intelligent power distribution box, effectively reducing the weight of the vehicle. At the same time, the built-in battery positive wiring harness adopts a cost-effective copper bus or aluminum bus structure to ensure the stability and safety of the connection, avoid the risk of external wiring harness wear, and greatly simplify the electrical layout of the vehicle.

[0045] Optimization of space utilization: In order to solve the problem of low internal space utilization of lithium-ion batteries, existing designs often adopt a 1P8S (1 parallel 8 series) layout, which only occupies half of the space. The present invention aims to maximize the utilization of the internal space of the battery pack and reduce space waste by improving the structural design.

[0046] This application realizes the real-time monitoring and fine management of key operating parameters of lithium batteries (including power, temperature, voltage, etc.) through integrated innovation. At the same time, the introduction of intelligent power distribution system can accurately match the actual maximum load requirements of power-consuming equipment, automatically adjust the fuse configuration, and significantly improve the accuracy and response speed of system protection. In addition, the system also optimizes the power line design, effectively reducing the dependence on large-size power wiring harnesses, thereby reducing costs while greatly improving the overall reliability and economic benefits of the product.

[0047] The system integrates digital intelligent power distribution technology to achieve intelligent system upgrades and improve vehicle performance and safety. Specifically, the present invention monitors key battery parameters in real time to achieve precise energy management and protection; at the same time, the innovative power distribution method can automatically adjust the fuse configuration according to the actual load requirements of the power-consuming equipment, thereby improving protection accuracy and response speed. In addition, the system of the present invention also optimizes the power line design, reduces the use of wiring harnesses, reduces costs and improves system reliability.

[0048] This application realizes the combination of lithium-ion batteries and intelligent distribution boxes through highly integrated design, intelligent management and multiple safety protection mechanisms.

[0049] Specifically, the lithium battery box 1: as the main structure of the entire system, it is used to accommodate the battery pack and other related electronic components. The box is designed with metal material, which has excellent heat insulation, fire resistance and corrosion resistance, and is stronger than the plastic structure of the original battery. Breathable valve 2: arranged on the top or side of the lithium battery box 1, used to adjust the internal air pressure of the box to prevent safety problems caused by gas expansion, and prevent external moisture and dust from entering. Mounting bracket 3: fixed on the vehicle chassis or transition bracket, used to support and fix the lithium battery box 1 to ensure the stability of the system. The mounting bracket 3 is designed with an adjustable structure to adapt to different installation environments. Grounding point 4: arranged on the lithium battery box 1, it is a connection point for electrical grounding, which eliminates the potential difference in the electrical system, prevents the risk of electric shock caused by charge accumulation, ensures the electrical safety of the system, and also helps to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). Inlet and outlet 5: Provides inlet and outlet for the battery cooling system, used to circulate coolant, control the operating temperature of the battery pack, ensure battery performance and service life, suppress the temperature of the power distribution control chip, so that the power distribution system can output large load. Connector 6: includes interfaces such as signal lines and power lines, used for electrical connection between the battery management system and the external control unit or other systems. Connector 6 is designed with a waterproof and dustproof structure. At the same time, the number of connectors 6 can be increased or decreased according to the power distribution needs to improve the environmental adaptability of the system.

[0050] First of all, it is clear that the intelligent power distribution system is a direct upgrade alternative to the traditional power distribution system. Before implementation, it is necessary to deeply understand and master the electrical schematic diagram of the original vehicle, which is the basis for ensuring the smooth conversion of the system. In the process of transforming the low-voltage power distribution system of the whole vehicle, the consideration of the intelligent power distribution solution should be incorporated from the front-end design stage. Therefore, when designing a new system or upgrading an existing system, it is necessary to fully plan the layout, interface and communication protocol of the intelligent power distribution to ensure the compatibility, scalability and efficiency of the system. Next, building a data platform is a key link in the implementation of the intelligent power distribution system. The platform must have functions such as data collection, real-time processing, safe storage, convenient retrieval and efficient query. By integrating advanced sensor technology, data processing algorithms and cloud storage solutions, comprehensive monitoring and intelligent management of the status of the vehicle's electrical system can be achieved.

[0051] During the specific implementation process, the following points should be noted:

[0052] (1) Interface standardization: Ensure the standardization of interfaces between the intelligent power distribution system and other vehicle systems (such as the battery management system, body control system, etc.) to achieve seamless connection and efficient communication.

[0053] (2) Security protection: Strengthen the security protection measures of the data platform and adopt technical means such as data encryption and access control to ensure the security of data transmission and storage and prevent information leakage or illegal tampering.

[0054] (3) User-friendliness: Design an intuitive and easy-to-use operating interface and reporting system so that non-technical personnel can easily understand the system status and perform necessary monitoring and operations.

[0055] (4) Continuous optimization: Establish a system maintenance and optimization mechanism, collect feedback based on actual usage, continuously optimize algorithms, upgrade software, and improve the system's intelligence level and user experience.

[0056] Through the above specific implementation methods, the intelligent power distribution system designed by the present invention can not only directly replace the traditional power distribution system, but also significantly improve the electrical system performance of the whole vehicle, contributing to the intelligent development of new energy vehicles.

[0057] From the above description, it can be seen that the present application achieves the following technical effects:

[0058] In the embodiment of the present application, an integrated setting is adopted, and the lithium battery box 1 is integrated with the intelligent distribution box to form an integrated intelligent power supply and distribution device, thereby achieving the purpose of deep integration of functions, thereby realizing the technical effects of improving space utilization, reducing system complexity and cost, and enhancing overall safety and intelligence level, thereby solving the problem that the prior art usually relies on a complex low-voltage power distribution system, which contains a large number of wiring harnesses, which not only increases the weight and cost of the vehicle, but also reduces the overall reliability of the system. At the same time, the layout and maintenance of these wiring harnesses also bring additional challenges; secondly, the traditional distribution system often has a lag in monitoring the battery status, and cannot accurately reflect the battery status in real time. This may cause changes in key parameters of the battery, which to a certain extent limits the system's timely identification and handling of potential faults; secondly, when a system fault occurs, the fault handling efficiency of the traditional distribution system is low and often requires manual intervention, which not only prolongs the fault recovery time, but may also have an adverse impact on the normal operation of the vehicle; in addition, the existing technology is generally extensive in energy efficiency management, and it is impossible to achieve refined control of energy use, resulting in serious energy waste; finally, from the perspective of safety protection, traditional distribution systems often rely on a fixed combination of fuses and relays to achieve overcurrent protection, but this method has limited protection accuracy and flexibility, and it is difficult to meet the technical problems of high safety performance requirements of new energy commercial vehicles.

[0059] Furthermore, a lithium-ion battery is arranged in the lithium battery box 1, and a plurality of single cells are arranged in series and in parallel inside the lithium-ion battery.

The real-time monitoring tasks of key parameters such as battery power, voltage, and temperature, which are jointly undertaken by the two, are completed through integrated circuit detection chips, further improving the system's integration and efficiency.

[0064] CAN bus digital power distribution: This invention adopts CAN bus technology to realize the comprehensive digitalization and intelligence of the power distribution system. It simplifies the wiring harness structure and reduces the physical connection points, thereby reducing the probability of failure, and improves the integration and flexibility of the system, providing convenience for the upgrade and maintenance of the vehicle electrical system.

[0065] Furthermore, an intelligent monitoring and fault diagnosis module is provided in the lithium battery box 1, and the intelligent monitoring and fault diagnosis module is connected to the lithium-ion battery and the intelligent distribution box respectively.

[0066] Specifically, intelligent monitoring and fault diagnosis: using advanced ECU and sensor technology, an intelligent monitoring network is built, which can detect circuit status, load conditions and fault information in real time, and perform intelligent analysis and processing. The integrated automatic fault diagnosis and isolation function can quickly locate and isolate the fault point when a fault occurs, effectively preventing the fault from spreading, ensuring the normal operation of other parts of the system, and reducing maintenance costs and time.

[0067] Furthermore, a protection mechanism module is provided in the lithium battery box 1, and the protection mechanism module is connected to the lithium-ion battery and the intelligent distribution box respectively.

This mechanism can monitor the operating status of electrical equipment in real time. Once an abnormal situation (such as current overload, short circuit, overvoltage, overtemperature, etc.) is found, effective measures such as cutting off the power supply and reducing the current are immediately taken to minimize the risk as quickly as possible.

[0069] Furthermore, it also includes: a remote monitoring and data analysis module, which is connected to the lithium-ion battery and the intelligent distribution box respectively. It can be understood that by realizing the comprehensive networking of distribution data, users can monitor the vehicle distribution status in real time through the background and cloud systems. At the same time, it also provides a rich data source for the big data management and in-depth application of the vehicle distribution system, helping to improve the level of intelligent management.

[0072] Specifically, the adoption of digital power distribution technology has promoted the technical improvement of vehicle power distribution management. Supporting OTA function enables the vehicle power distribution architecture to be flexibly adjusted and optimized according to actual needs, enhancing the scalability and adaptability of the system.
