Vehicle to grid (V2G) describes a system in which power can be fed back to the electrical power grid from an electric drive vehicle (EDV) when connected to the grid and not in use. Alternatively, when the vehicle batteries need to be charged, the flow can be reversed and electricity can be drawn from the electrical power grid to charge the battery. Taking into account the specific features of the...
With breakthroughs in battery technology, plug-in hybrid electric vehicles (PHEVs), jointly powered by an electric drive and an internal combustion engine are becoming a realistic alternative. In a PHEV, the battery is charged by the grid and the electric machine plays the major role in the vehicle drive so that the engine is only required to provide extra torque when accelerating and to drive the...
Powertrain is a key component of the parallel electrical hybrid vehicle for which can control energy flow of the system. According to the basic configuration of parallel electrical hybrid powertrain, the control strategy based on limiting work range of engine is discussed in the paper. As a load adjusting device, the motor uptake power and maintain battery working on the range of high efficiency when...
Fuel cell electric vehicle has very good application foreground for it has some advantages, such as high efficiency and little emission, etc. In order to characterize the structure of hybrid power system for fuel cell electric vehicle, the project of parallel hybrid power system was brought forward, which consisted of fuel cell, NIH battery and DC/DC converter. The power flow of hybrid power system...
