At the beginning of 2020, the 100-person electric car will lead, combined with a number of organizations such as enterprises and institutions, colleges and research institutes, established the Dynamic Lithium Ion Battery Full Lifecycle Joint Innovation Center (hereinafter referred to as the battery center). The battery center will focus on demonstration project implementation and promotion of management mechanisms, technology upgrades, new models (business models and promotion patterns) related to dynamic lithium-ion batteries. The battery center will use a hundred people in the power of the electric vehicle, with the support of the unit, battery, battery, charging pile, insurance, second-hand car, big data, power grid, battery recycling, etc.
Battery health diagnosis, value assessment, standard development, policy support, battery management, etc. Data integrity of the dynamic lithium-ion battery will directly affect the battery asset assessment pricing With the development of the new energy vehicle industry, the use and value of battery data will continue to improve. At present, the powerful lithium-ion battery full lifecycle data is generally in the form of closed islands, unable to interconnect, unable to achieve the accurate assessment of power lithium-ion battery assets, which in turn hinders the ladder utilization, financial, insurance and new energy used cars.
Innovative technical methods will increase the accuracy of the power lithium-ion battery data acquisition compared to traditional battery wired monitoring methods, wireless BMS integrate all integrated circuits, hardware and software, such as power, battery management, RF communications, and system functions in a single system level. In the product, no longer use the signal sampling line to connect the battery, saving up to 90% of the wire harness and 15% of the battery pack volume, improves design flexibility and manufacturability, and supports ASILD-level functional security and modular security. Inside the battery center, hundreds of people and ADI initiated the "Operational Signal Based on Wireless Transmission and Cloud Service and Health Status and Health Status Monitoring", the project is based on the radio battery management system, which implements the electrical cell level wireless monitoring, and wireless battery Advantages of the management system further extension.
Not only do not reduce the cost of car manufacturing, but the flexible battery layout also allows electric automotive industrial design more optimized. The wireless battery management system can achieve data real-time acquisition from battery production, warehousing, transportation, vehicle production, road driving, maintenance, to the complete life cycle of used car transactions and battery ladder. This information can be passed to the cloud, the battery factory and the vehicle factory can extend the battery through these data and the life cycle of the entire electric vehicle; the industrial chain partner can use these data to evaluate the health status of the battery and the residual value of the battery, promote electric vehicle used car The health and sustainable development of the market, add consumers about the purchase confidence of electric vehicles; when the battery is retired, it can still use the design method to supply assessment recommendations for the ladder according to the actual situation of SOH.
