Nissan aims to boost EV performance, safety with 'moving battery pack'

Nissan has patented an innovative "active mount" system for electric vehicle (EV) battery packs designed to enhance performance and safety by dynamically shifting the battery's position within the vehicle. Unlike traditional rigid mounting, Nissan’s system uses actuators controlled by a central computer that processes data from various sensors (measuring pitch, yaw, acceleration, weight distribution, and more) to move the battery pack laterally and longitudinally. This real-time adjustment aims to optimize traction, handling, and stability—for example, improving acceleration by shifting weight rearward, reducing understeer during turns, enhancing braking control, and even repositioning the battery to mitigate damage during impacts or rollovers. The technology could initially appear in high-end models, such as a future GT-R, and would provide adaptive responses to driving conditions like towing uphill or high-speed maneuvers. However, challenges remain, including increased system complexity, potential compromises in cabin or battery space, and additional energy consumption due to moving a heavy battery pack. Nissan
