RETRACTED: Energy recovery data characteristics extraction of flywheel energy storage control system for vehicular applications

Abstract

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.

Performance Analysis of a New Vehicle Braking Energy Recovery System

“…Especially in urban road operation conditions, about 30% of the energy is lost during braking condition. At present, the specific device can recover part of the vehicle kinetic energy, and most researches use battery-motor to achieve energy recovery [2][3][4]. In the above studies, the vehicle kinetic energy is temporarily stored in the battery and released on the next acceleration.…”

Development of a Flywheel Hybrid Power System in Vehicles without the Electric Drive Device Rated Capacity Limit

“…The loss of the vehicle braking energy accounts for approximately 10-30% of the total energy consumption in urban driving conditions [1][2][3], and braking energy recovery devices can convert part of the vehicle kinetic energy into mechanical energy or electrochemical energy for recovery and storage [4][5][6]. To date, most studies have focused on converting the kinetic energy of vehicle braking into electrochemical energy, recovering and storing part of the braking energy through motor batteries [7,8].…”

Preliminary design of an alternative energy storage system for a city car based on flywheel

“…As per batteries, the obtainable driving range is the main problem since the weight of the flywheel increases the energy request to drive the car. Several form of hybrid powertrain layouts tried to partially solve the problem [18,19]. As shown in [9], both series and parallel hybrid configuration are available.…”

“…This creates room and safety problems. On the other hand, parallel configuration [18,25] offers several possibilities mainly depending on where the flywheel is placed into the power-chain. During the last decade, however, this technology has become so mature that some of the major car manufacturers have succeeded in installing it on series models ( [16,20,4,23]).…”
