Collaborations that express technological revolution and innovation are more and more frequent in the field of electric motors. In one of the latest partnerships, Analog Devices and Lotus are likely to be protagonists, committed to the implementation of a wireless battery management system (wBMS). With the elimination of 90% of the wiring equipping the car, the design freedom would increase and, at the same time, it would be possible to reduce by 15% the physical sizes of the battery pack and consequently the overall car weight. And all this without any kind of performance loss. The system is managed by a central unit that dialogues with the various battery modules by means of a wireless system.
Benefits should be mirrored on all future electric Lotus models, probably starting from the electric Type 132 SUV whose release on the market is expected in 2022.
«Lotus has a stellar reputation for building high-performance, long-lasting race and road vehicles, and many reach classic status,” said Roger Keen, General Manager of E-Mobility Group at Analog Devices. “Together, we’ve reimagined what is possible and developed a game-changer for the electric vehicle industry: a new ultralightweight powertrain architecture and a wireless battery management system that enables peak performance as well as a more sustainable environment for a healthier planet».
Finally, the floor is given to Richard Lively, Director, Propulsion and Chassis Engineering Lotus Cars: «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. “The removal of the wire harness for wBMS ensures that Lotus can offer a lightweight solution that optimizes performance and is consistent with our brand of delivering powerful performance cars with exceptional handling».
