“…12 Energy conversion mode is the difference between these two styles; the electrical powertrain needs to convert the energy from mechanical to electrical and then back to mechanical. A motor/generator should be attached to the flywheel and an additional motor/generator which is mechanically attached to the transmission system of the vehicle.…”

“…While regenerative braking occurs, high power levels can be absorbed by the flywheel energy storage system (FESS) at efficiencies far superior to those attainable by advanced batteries alone. [12][13][14][15] Kuo and Hsieh 16 pointed out that the FESS can efficiently reduce the output peak power and the load intensity of the electric vehicle motor; the regeneration energy efficiency is higher than the lithium-ion battery, and the comprehensive energy consumption is reduced to 22.7%. Van Berkel et al 17,18 designed a flywheel transmission system equipped with continuously variable transmission (CVT) and effectively improved the specific fuel consumption by some certified driving cycle simulation with control algorithms.…”

Flywheel energy storage system seems to be especially well suited to hybrid powertrain, which allows regenerative braking and power augmentation during acceleration in automotive vehicles. This article presents a novel electrical flywheel hybrid system through the analysis of the dynamic response of energy recovery process and the transmission characteristics of flywheel energy storage system. The power transmission process and energy flow of the vehicle with flywheel energy storage system were elaborated during braking. Energy recovery performance evaluation indexes were put forward, and the energy conversion characteristic test was conducted by experimental rig. The experimental result shows that the use of low-power motor speed control for gear ring can reduce the degree of jerk of transmission powertrain during energy recovery process and improve the energy recovery rate, and the net energy recovery rate tends to a stable value of 33%. The research extracts some features for flywheel energy storage control system and provides a theoretical basis for the further vehicular applications research.

This study is concerned with the magnetic force models of magnetic bearing in a flywheel energy storage system (FESS). The magnetic bearing is of hybrid type, with axial passive magnetic bearing (PMB) and radial hybrid magnetic bearing (HMB). For the PMB, a pair of ring-type Halbach arrays of permanent magnets are arranged vertically to support the rotor weight. For the HMB, a set of ring-type Halbach array is placed on the rotor side, which corresponds to coil sets on the stator side. The HMB can produce both attraction and repulsion forces on the radial direction, depending on the direction of the coil currents. It is found that the ring-type configuration and the differential winding scheme for coil sets can yield linear magnetic force models for both PMB and HMB. Based on the obtained magnetic force model, an integral sliding mode controller is designed for the stable rotor levitation in the radial direction. The experimental results show that the rotor can be stabilized to the bearing center, verifying the accuracy of the magnetic force models and effectiveness of the levitation controller.
