• Nissan’s ‘moving battery pack’ patent aims to boost EV safety, performance The system will use actuators controlled by a central computer to decide optimal position of the battery pack under driving conditions. • Japanese carmaker Nissan has patented an ‘active mount’ for the battery pack to boost performance and safety in electric vehicles (EVs). • A document filed with the US Patent and Trademark Office (USPTO) shows how Nissan may be looking to leverage the weight of a battery pack as a major advantage for traction and control. • The battery pack of an EV is not only its most expensive component but also one of its heaviest. • Even though the earliest EV manufacturers were not legacy car makers, they did use a legacy trick: mounting the battery pack rigidly to the vehicle’s chassis to strengthen the design. • With demands for a higher range, battery packs have grown bigger and heavier, but the Cell-to-Body architecture has become an industry-standard approach, making its way into mass production as well.
Article Summaries:
- Nissan has filed a U.S. patent for an “active mount” that would allow an electric‑vehicle battery pack to shift position during driving. Actuators, controlled by a central computer that uses data from existing vehicle sensors, could move the pack left‑right and front‑back to optimize weight distribution for traction, handling, and safety. The system could, for example, relocate the pack to improve acceleration, reduce understeer, or protect the battery in a rollover. While the concept promises performance gains, it raises concerns about added cost, space, and energy consumption, and it remains unclear whether the technology will reach production.
