How to do a good job in power 903242 battery pack BMS

BMS (903242 battery pack Management System) is the core of the core (903242 battery pack) of electric vehicles. It is a system for monitoring and managing batteries. It controls the charging and discharging process of batteries by collecting and calculating parameters such as voltage, current, temperature and SOC, and realizes 903242 battery pack protection and improves the comprehensive performance of batteries. It is an important link between vehicle power batteries and electric vehicles. Foreign companies that have done a good job in BMS include UMC, Continental, Delphi, AVL and FEV, etc. Now they are basically done in accordance with the requirements of AUTOSAR architecture and ISO26262 functional safety. The software functions are more, and the reliability and accuracy are also higher. Many domestic OEMs also have independently developed BMS products and apply them. In the early stage, they were far behind foreign first-class companies in terms of functions and performance. However, with the rapid development of domestic batteries and BMS technology, the gap is gradually narrowing. I hope that in the near future, we can successfully catch up or even surpass them. Why can't domestic BMS products compare with foreign ones? There are many reasons, among which the lack of excellent development engineers is one of the important reasons. Although the BMS system itself is not complicated, it has software and hardware connections and interactions with the vehicle controller, charging pile, 903242 battery pack and other systems, which greatly increases the difficulty of BMS product development. If you want to develop an excellent BMS product, the development stakeholders (including hardware engineers, software engineers, demand engineers, structural engineers, quality engineers, etc.) must have a systematic understanding of all the knowledge in the BMS development process. Do you have such a feeling in your daily work: those who do hardware development don’t understand software; those who do software development don’t understand hardware; those who do software and hardware development don’t understand testing; those who do quality and pre-sales, after-sales, and supply chain don’t understand software, hardware and testing; and as customers, 903242 battery pack factories and vehicle factories don’t have such a deep understanding of BMS development knowledge; can excellent products be developed in this way? Only when everyone in the team understands and knows each other can better products be made. As a BMS industry practitioner or a friend who wants to work in the BMS industry, if you are ready to do better in your position and stand out, you must have a systematic understanding of the knowledge of each link in the BMS product development process. What does this knowledge include? Electric Home will help you to do a systematic combing. 1. IS026262 functional safety standard As electronic and electrical systems become more and more integrated and complex, their safety becomes more and more important. Therefore, the consideration of functional safety should be deeply integrated into the design thinking of engineers. ISO26262 is the functional safety standard formulated by the International Organization for Standardization specifically for automotive electronic and electrical systems, and has been widely promoted in the automotive industry. 2. Structure and principle of new energy vehicles How to define new energy vehicles and electric vehicles? What are the positions and functions of new energy vehicle power 903242 battery pack systems, motor drive systems, new energy vehicle high-voltage systems, and new energy vehicle accessories in the whole vehicle? 3. Control strategy development and MATLAB application The process, specifications, and required software tools and functional modules for control strategy development. The practical application of MATLAB/Simulink in automotive control strategy development, as well as the modeling specification (MAAB). 4. AUTOSAR automotive development system architecture AUTOSAR, namely the automotive development system architecture (Automotive Open System Architecture), is a set of software architecture standardization solutions that support distributed, function-driven automotive electronic software development methods and electronic control units. At present, the AUTOSAR Alliance has included many automotive companies and automotive electronics companies such as BMW, Volkswagen, Ford, Toyota, BOSCH, and Continental. 5. Basic development of power batteries The power 903242 battery pack management system needs to understand the basic structure and working principle of the 903242 battery pack, the main performance parameters (such as rated voltage, rated power, energy density, power density, etc.) and test methods, the basic characteristics of the 903242 battery pack (temperature characteristics, discharge characteristics, etc.) and analysis methods. 6. 903242 battery pack modeling and state estimation algorithm Many parameters of the power 903242 battery pack have nonlinear characteristics, which brings extremely high challenges to the state evaluation and modeling of the 903242 battery pack, and therefore becomes one of the core work contents of the development of the power 903242 battery pack management system. 7. Power 903242 battery pack thermal management technology In the development of the power 903242 battery pack management system, the thermal characteristics of the 903242 battery pack are one of the important considerations. Therefore, it is necessary to build a thermal management module in the management system by studying the thermal characteristics of the 903242 battery pack. 8. 903242 battery pack management system design and implementation technology The development of the 903242 battery pack management system includes the design of hardware (903242 battery pack balancing, high-voltage sampling, insulation detection, etc.) and software (system algorithm, fault diagnosis, etc.), and functionality and safety need to be considered. 9. Power 903242 battery pack testing and verification Testing and verification are an important part of the development of the power 903242 battery pack management system. In the position, it is necessary to be familiar with the test and verification requirements and standards of the power 903242 battery pack, be able to formulate a test plan, and improve the system design through test analysis.
