Nissan's moving battery pack technology for EVs

Nissan has patented an unusual technology for electric vehicles—a battery pack that can move inside the vehicle's body while driving. While most EVs feature a rigidly integrated battery in the floor, the Japanese automaker is proposing an alternative approach.

According to the patent application, the battery is housed in a special frame and can shift along the longitudinal or transverse axis via electric actuators. Control is managed through a suite of sensors, including accelerometers, gyroscopes, cameras, and mass distribution sensors, which analyze the car's behavior and adjust the battery's position accordingly.

The idea is simple yet radical: use the battery's weight as an active tool for dynamics. Shifting the center of gravity can reduce body roll, improve balance in corners, and enhance stability at high speeds. Essentially, Nissan aims to turn the main drawback of EVs—the battery's substantial mass—into an advantage. The system can operate in various modes, such as sport, adapting mass distribution to specific driving conditions. Theoretically, this could cut lap times on a track and improve steering precision.

For now, this is just a patent, and the path to production might be long. However, the concept itself shows that Nissan continues to explore unconventional solutions to make electric vehicles not only quick in a straight line but also genuinely engaging to drive.
