Electric vehicles-pursuing efficiency

IEEE Spectrum, 1992
The approaches being used to make electric vehicles (EVs) highly efficient given the limitations of EV batteries are described. They include reducing vehicle weight, aerodynamic drag, tire rolling resistance, and bearing friction; eliminating brake drag; and increasing the efficiency of the electric motor and its control electronics.

Improved efficiency in domestic electricity use

Energy Policy, 1979
Abstract This paper describes how domestic appliances (excluding water and space heaters) and lighting devices can be redesigned to use electricity more efficiently. Three levels of conservation strategy are analysed: ‘moderate’, ‘strong’ and ‘radical’. These result in the reduction of electricity consumption to 80%, 50% and 35% respectively, without

Efficiency optimization of electrical devices

2018 23rd International Scientific-Professional Conference on Information Technology (IT), 2018
Research goal of this paper is to optimize two different electrical devices with respect to their efficiency. First one is a synchronous motor with surface mounted magnets and the second one is an inductor which is an integral part of LCL filter. Optimization in case of the motor is done by varying two design parameters: rotor diameter and the axial ...

Self‐Assembled Interlayer Enables High‐Performance Organic Photovoltaics with Power Conversion Efficiency Exceeding 20%

Advances in Materials
Interfacial layers (ILs) are prerequisites to form the selective charge transport for high‐performance organic photovoltaics (OPVs) but mostly result in considerable parasitic absorption loss.
