Analog Devices, Inc. announced that renowned British performance brand Lotus Cars is planning to incorporate ADI’s wireless battery management system (wBMS) in its next-generation electric vehicle (EV) architecture. ADI’s wBMS was selected for its increased design flexibility, battery repairability and lighter weight. The engineering collaboration will enable Lotus to safely propel its future EV fleet and continue pushing the limits of design and technology.
ADI’s wBMS technology eliminates the traditional wired harness, leading to a reduction of up to 90% in the wiring and 15% of the volume in the battery pack. It also improves design flexibility and manufacturability, without compromising range and state of charge accuracy over the life of the battery. ADI’s wBMS enables simplified assembly and disassembly of battery packs to ensure faulty battery cells can be removed and repaired quickly and efficiently.
The body architecture of every Lotus car is designed for peak performance. The design flexibility of wBMS will enable Lotus’ engineers to freely design the vehicle and fit the battery pack into the design, instead of designing the car around it. Moreover, because ADI’s wBMS enables maximum energy use per cell required for optimized vehicle range, it aligns with Lotus’ focus on durability.
It is crucial that the battery keep up with the longevity of the Lotus vehicle. wBMS enables state-of-health measurement and simplified assembly and disassembly of battery packs to ensure faulty battery cells can be removed and repaired efficiently. With wBMS, serviceability is easier and faster for both road vehicles and trackside since the battery modules are software programmable for quick and convenient over the air updates. The cell controller lives with the battery module for life as one serviceable unit, furthering the simplified service model.
