Vehicle-to-grid power (V2G) uses electric-drive vehicles (battery, fuel cell, or hybrid) to provide power for specific electric markets. This article examines the systems and processes needed to tap energy in vehicles and implement V2G. It quantitatively compares today’s light vehicle fleet with the electric power system. The vehicle fleet has 20 times the power capacity, less than one-tenth th...

A dual mechanical port machine (DMPM) is used as an electrically variable transmission (EVT) in hybrid electric vehicle (HEV). In the conventional HEV, this machine is replaced by a planetary gearbox and two electric machines and makes this structure simpler. This paper presents field oriented control (FOC) for DMPM. For HEV application, drive efficiency and wide operating speed range are impor...

This paper gives a brief introduction to the background of the development of electric vehicles in China, a detailed description of the principle of the SOC of batteries in electric vehicle, introduces the new SoC technology progress, and to illustrate the author team of these technology to repeat the experiment results, and finally puts forward the SOC of batteries in electric vehicle future r...

Electric vehicle (EV) development in the Kathmandu Valley began in 1993 as a response to the urgency of a severe air pollution situation. The dynamics of government intervention, non-governmental organization advocacy, international donor support, and private sector involvement all shaped EV implementation in various ways. Its success led other South and East Asian cities to view it as a model ...

What does the invention do? This invention presents a modular system of units that can drive, brake, steer and suspend an electric vehicle. These units are also referred to as “Robot Wheels” because they are autonomous elements that can be connected to any electric vehicle chassis. Each unit (Fig.1) includes an electric motor, a steering element, a suspension arm and a connector. The system fit...

The project E-Vectoorc (Electric Vehicle Control of Individual Wheel Torque for Onand Off-Road Conditions) targets the development of an integrated controller for vehicle dynamics and energy efficiency for fully electric vehicles with one to four electric motors. The project is funded within the 7th European Union Framework Programme and unites two OEMs (Jaguar Land Rover, Skoda Auto), one supp...
