ADI wireless BMS helps Lotus Cars redefine EV mobility
The 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, while improving design flexibility and manufacturability.

Analog Devices has announced that renowned British performance brand Lotus Cars is planning to incorporate its wireless battery management system (wBMS) in its next-generation electric vehicle (EV) architecture. The ADI 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.

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. wBMS enables simplified assembly and disassembly of battery packs to ensure faulty battery cells can be removed and repaired quickly and efficiently.

“We worked closely with Analog Devices to integrate wBMS into our new Lightweight Electric Vehicle Architecture (LEVA), which will be the basis for all future Lotus EVs,” said Richard Lively, Director, Propulsion and Chassis Engineering, Lotus Cars. “The removal of the wire harness for wBMS ensures that Lotus can offer a lightweight solution that optimises performance and is consistent with our brand of delivering powerful performance cars with exceptional handling.”
