Recently, the “China Electric Vehicles Forum (2021)” was held in Diaoyutai State Guesthouse, Beijing. With the theme of “New Development Pattern and Auto Industry Reform”, the forum conducted in-depth discussions on hot issues such as zero-emissions and electrification of automobiles, energy conversion and transformation of traditional auto companies, and the prospect of future transportation and travel changes.

The field of new energy vehicle power batteries has always been the focus of the annual forum of the Hundreds of Peoples Association. In the past year, new products and new business models in the power battery industry have continued to emerge. How to use battery technology innovation, model and management innovation to further enhance battery life cycle safety, and how to accelerate the application of big data and platformization in battery production R&D, application, operation, recycling and other life cycle applications have once again become this conference Key topics.

The China Electric Vehicles Association has been committed to breaking the limitations of industry, discipline, ownership and department, and building a platform to promote multi-field integration and collaborative innovation through research and exchanges. In early 2020, it will cooperate with the industry’s leading high-performance analog technology provider ADI The joint establishment of the “Battery Life Cycle Joint Innovation Center” is one of the important measures. The platform unites upstream and downstream companies in the industrial chain such as battery manufacturers, automakers, charging and swapping infrastructure providers, and battery echelon utilization manufacturers to jointly achieve continuous monitoring of the key characteristics of batteries, the core component of electric vehicles, to achieve more accurate, Safe battery life cycle management provides important data support for the collaboration of related industry chain enterprises.

Multi-party joint assistance on the platform, real-time data monitoring to relieve key constraints

“Data is playing an increasingly important role in our industry. As value shifts from data delivery to the creation of data insights, data mining has become a new industry focus.” Vincent Roche, President and CEO of ADI, in his annual outlook for the industry in 2021 Pointed out. Data can also play a key role in solving the key market development constraints of electric vehicles. The “Battery Life Cycle Joint Innovation Center” initiated by ADI and Bairenhui is the use of battery big data to solve the main problems in the development of the electric vehicle industry. The original intention of the dilemma.

At present, there are two major factors restricting the development of the electric vehicle market: first, the spontaneous combustion accidents of electric vehicles that occur from time to time cancel the purchase plan of many potential users; secondly, the residual value of key large-size batteries is difficult to assess, which leads to poor trading of second-hand vehicles. , The cascade utilization of battery recycling is also facing a bottleneck. The risk of spontaneous combustion can be pre-warned by real-time monitoring and analysis of the change characteristics of key data such as battery operating temperature, voltage and current. The residual value assessment of used car batteries can also provide accurate and authoritative data through real-time battery monitoring. The key to solving these two problems is to build a data collection and analysis platform that can be monitored in real time, and a wireless battery management system (WBMS) that supports real-time data collection. ADI and China Electric Vehicles Association have reached a full consensus on the idea of ​​solving this problem, and the “Battery Life Cycle Joint Innovation Center” came into being.

Under the banner of the Innovation Center, Bairenhui and ADI initiated the project “Car lithium battery life and health monitoring based on wireless transmission and cloud services”. This is a technology and platform solution based on the ADI wireless battery management system. Real-time battery data monitoring can achieve full life cycle battery safety and performance monitoring. At present, ADI has provided an independently developed battery life cycle end-cloud combined management platform demonstration system for the project, which can realize the battery from the manufacturing process (differentiated and formed), warehousing, battery transportation, vehicle production, road driving, maintenance, to second-hand Monitoring and management of the complete life cycle including vehicle trading and battery echelon utilization.

ADI and the China Electric Vehicles Association jointly build an intermediate cooperation platform and share the platform with industrial enterprises for the utilization and development of the entire industrial chain. OEMs have a large number of end-user battery operating data; battery companies are very familiar with battery characteristics and can provide effective data analysis capabilities; battery tier application merchants and second-hand car buyers need neutral and authoritative battery performance monitoring data… based on the innovative platform technology , Can effectively integrate resources and demands on the industrial chain, and realize long-term positive interaction and cooperation in the industry. At present, the innovation center has received participation and support from well-known companies in various fields, including lithium battery manufacturers, automakers, charging and swapping infrastructure, and battery recycling. Enterprises are already in hot contact.

The wireless BMS monitoring solution advocated by the Joint Innovation Center can cover the full life cycle of electric vehicle batteries

Wireless battery management system + cloud platform, combining terminal and cloud to create a perfect solution

As one of the world’s leading providers of automotive Electronic semiconductor solutions, ADI’s automotive solutions cover automotive electrification, cockpit electronics and infotainment systems and autonomous driving technology. In terms of electrification, in addition to battery monitoring solutions, ADI has broken through the traditional wired connection bottleneck of the traditional battery management system based on its patented embedded wireless sensor network technology in recent years, and innovatively proposed a wireless battery management system solution. In the project of “Car lithium battery life and health monitoring based on wireless transmission and cloud services”, ADI’s wireless battery management system and cloud platform constitute a perfect end-cloud combined system platform.

The battery connection of traditional electric vehicles is very complicated, and the corresponding wiring harness connection is required between the battery modules. The wireless BMS integrates all integrated circuits, hardware and software such as power supply, battery management, radio frequency communication and system functions into a single system-level product. It is necessary to use the signal sampling line to connect the battery, which saves up to 90% of the wiring harness and up to 15% of the battery pack volume, improves design flexibility and manufacturability, and supports ASIL-D safety and module-level safety.

ADI announced the launch of the first wireless battery management system for mass-produced electric vehicles in September 2020

The battery-level full-process wireless monitoring based on the cloud platform will undoubtedly extend the advantages of the wireless battery management system. It not only achieves cost reduction in automobile manufacturing, but also allows more flexible battery layouts to allow greater autonomy in the industrial design of electric vehicles, and at the same time Real-time data collection and cloud platform-based monitoring and analysis are realized throughout the entire process of battery production, warehousing, and transportation. This information can be transmitted to the cloud in real time, and auto manufacturers can use this data to extend the life cycle of batteries and the entire electric vehicle; industry chain partners can use this data to assess the health and residual value of the battery, and promote the health of the electric vehicle used car market. Continued development makes consumers willing to buy electric vehicles; even when the battery cannot continue to be used in electric vehicles, it can still be effectively used in echelon utilization scenarios such as energy storage based on the actual accurate capacity assessment.

The whole industry chain is integrated and interacted to jointly participate in the grand event of the electric vehicle industry

The goal of the Joint Innovation Center is clear-to attract more leading companies in the industry chain to join to form a cross-industry, cross-disciplinary, and cross-departmental industrial research platform, and set out to investigate and solve major challenges in the field of new energy vehicle batteries, including battery safety and battery valuation And a series of key issues such as data sharing. At present, the Innovation Center has built a management platform that integrates the whole life end of the battery and the cloud, which has basically achieved complete functions. How to optimize the cloud platform algorithm for the battery characteristics of various battery manufacturers, achieve higher quality monitoring, more timely response, and cover more vehicles, achieve better data services for vehicle manufacturers, and provide more services For commercial development enterprises of cascade batteries, more upstream and downstream industries need to join the platform to participate in the grand event.
