Analog Devices Ltd – Analog Devices Wireless BMS Helps Lotus Cars Redefine Mobility in Electric Vehicles
05 October 2021
Analog Devices, Inc. has announced that Lotus Cars, a renowned UK performance brand, is considering integrating ADI’s Wireless Battery Management System (wBMS) into its next-generation electric vehicle architecture.
ADI’s wBMS was selected for its increased design flexibility, battery repairability and lighter weight. The technical collaboration will allow Lotus to safely power its future electric vehicle fleet and to continue to push the boundaries of design and technology.
ADI’s wBMS technology eliminates the traditional wiring harness, reducing cabling by up to 90% and battery volume up to 15%. It also improves design and manufacturing flexibility without compromising range and state-of-charge accuracy over battery life. ADI’s wBMS enables simplified assembly and disassembly of battery packs to ensure faulty battery cells can be removed and repaired quickly and efficiently.
âWe have worked closely with Analog Devices to integrate wBMS into our new Light Electric Vehicle (LEVA) architecture, which will form the basis for all future Lotus electric vehicles,â said Richard Lively, Director, Propulsion Engineering and of the chassis, Lotus Cars.
âThe removal of the wiring harness for wBMS ensures that Lotus can offer a lightweight solution that maximizes performance and is consistent with our brand of delivering powerful performance cars with exceptional handling. ”
The body architecture of every Lotus car is designed for optimum performance. The design flexibility of wBMS will allow Lotus engineers to freely design the vehicle and integrate the battery into the design, instead of designing the car around it. Additionally, because ADI’s wBMS enables maximum use of the energy per cell required for optimized vehicle range, it aligns with Lotus’s focus on sustainability.
âLotus has an excellent reputation for building high performance and durable race and road vehicles, and many are achieving classic status,â said Roger Keen, general manager of the E-Mobility group at Analog Devices.
âTogether, we’ve rethought what’s possible and developed a game-changing element for the electric vehicle industry: a new ultralight powertrain architecture and a wireless battery management system that enables peak performance as well as a more sustainable environment for a healthier planet. “
It is crucial that the battery matches the longevity of the Lotus vehicle. wBMS helps measure health and simplify battery pack assembly and disassembly to ensure faulty battery cells can be removed and repaired efficiently. With wBMS, maintenance is easier and faster for on-road and trackside vehicles, as the battery modules are software programmable for quick and convenient live updates. The cell controller lives with the battery module for its entire life as a serviceable unit, further enhancing the simplified service model.
