Characterization of Flywheel Energy Storage System for Hybrid Vehicles

Pullen, K. R. & Dhand, A. (2014). Characterization of Flywheel Energy Storage System for Hybrid Vehicles. Paper presented at the SAE 2014 World Congress & Exhibition, 08-04-2014 - 10-04-2014, Detroit, USA. doi: 10.4271/2014-01-1796


Flywheels are excellent secondary energy storage devices and several applications in road vehicles are under development. They can be used in hybrid vehicles with an internal combustion engine (ICE) as the prime mover or can be used in hybrid energy storage (HES) to complement the battery. When used in HES, they are utilized to load level the battery so as to protect it from peak loads and enhance its capacity and life. This paper deals with defining the main characteristics of the flywheel for an application as a secondary energy storage device for an electric vehicle. Various strategies for defining flywheels are explained. A real world customer usage data is also presented. This data is analyzed and its results are used to support the selection of the flywheel characteristics. The results show that the chosen flywheel is sufficiently sized to perform its intended tasks for a c-segment passenger car electric vehicle.
