Analog Devices Introduces the Automotive Industry's First Wireless Battery Management System for Electric Vehicles

my country, Beijing-September 11, 2020-Analog Devices, Inc. (Nasdaq: ADI) announced the launch of the industry's first wireless battery management system (wireless BMS), allowing automakers to more flexibly expand the electric vehicle platform to a variety of models to achieve mass production. As the first wireless battery management system for mass-produced electric vehicles, the wireless BMS will be unveiled for the first time in mass-produced vehicles equipped with GM's Ultium battery platform. ADI's wireless BMS eliminates the need to use traditional wiring harnesses, saves up to 90% of the wiring harness and up to 15% of the battery pack volume, improves design flexibility and manufacturability, and does not affect the mileage within the battery life. Number and precision. ADI’s 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 supports ASIL by adopting ADI’s proven industry-leading BMS battery cell measurement technology －D security and module-level security. By improving the accuracy during the life of the vehicle, the wireless BMS system can maximize the energy utilization of a single battery cell, thereby achieving excellent vehicle mileage, and supporting safe and sustainable cobalt-free battery chemistries, such as lithium iron phosphate (LFP) ). Patrick Morgan, vice president of ADI's Automotive Division, said: 'The shift from wired to wireless connection of battery packs enables automakers to expand their electric vehicle platforms to a variety of models to meet the evolving needs of consumers. Our wireless BMS solution Not only can the manufacturing process be simplified, but new systems can be built based on wireless data, thereby accelerating the industry’s progress towards a sustainable future. We are honored to be able to work with General Motors to bring this breakthrough system innovation to the market.' Additional systems Features enable the battery to measure and report its own performance, improve early failure detection, and optimize battery pack assembly. From battery assembly to storage and transportation, to installation, maintenance and echelon utilization, remote data monitoring can be achieved throughout the battery life cycle. ADI and General Motors recently announced a partnership to jointly use wireless BMS technology for General Motors' Ultium battery platform. ADI's wireless BMS technology helps extend the Ultium platform to GM's future models, including different sub-brands and model segments (from trucks to performance cars, etc.). Kent Helfrich, Executive Director of Global Electrification and Battery Systems at General Motors, said: 'We are very pleased to be able to work with ADI to jointly use wireless BMS technology in production as part of our Ultium battery platform. ADI's wireless BMS technology can further advance us. With the development of electrification of the car series, we look forward to continuing to cooperate with ADI to jointly carry out innovations in safety, quality and performance.'
