The INSTAR flywheel energy storage system (FESS) is ideally suited for frequent stop-and-go urban driving conditions. The flywheel, acting as a mechanical battery, stores the absorbed braking energy for only 1-2 minutes before being sent either back to the drive motor or to the main chemical battery pack.


This allows for:


• Smaller overall size


• Conventional, cost-effective materials


• No magnetic bearings or high vacuum requirements
