Hybrid vehicles are an important step toward reducing global petroleum consumption and greenhouse gas emissions. Flywheel energy storage in a hybrid vehicle combines high energy density and high power density, yet requires a highly efficient continuously variable transmission with a wide operating range. This paper presents a novel solution to coupling a high-speed flywheel to the drive train o...

The high efficiency of the flywheel hybrid powertrain, as well its power characteristics, can help to meet energy/power conversion needs, which may prove be promising. Moreover, powertrain reduce dependence on batteries. This paper presents EC-BERS in order capture more mechanical than rated power, and charge/discharge cycles battery. In this new energy recovery system, maximum torque obtained ...

This study aimed to analyze the effects of power training using traditional vertical resistance exercises versus direction specific horizontal inertial flywheel training on performance in common sport-related tasks. Twenty-three healthy and physically active males (age: 22.29 ± 2.45 years) volunteered to participate in this study. Participants were allocated into either the traditional training...

In this study, a novel magnetic suspension flywheel battery with multi-function air gap is proposed. Based on the unique gap, degrees of freedom between control circuits can be independent each other, reducing coupling effect freedom. The proposed system topology inherits advantages battery. However, due to breakthrough overall in flywheel, and protection measures, has more precise design circu...

Abstract. This project further investigates a model of a simplified internal combustion engine considered by Kranc in 1977. Using Euler’s method for ordinary differential equations, we modeled the interaction between the engine’s flywheel and thermodynamic power cycle. Approximating with sufficiently small time intervals (0.001 seconds over a period of 12 seconds) reproduced Kranc’s results wit...

The main problems of contemporary energyhungry society are steep fluctuations in consuming: short-time power peaks are mirrored in the overdimensioned infrastructure. Applications are operating at underload most of the time – a circumstance, not favourable for economic reasons. The idea of load levelling by the means of storage buffers is well known, but hard to implement, especially in kWh and...
