differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

Hybrid energy storage system (HESS) can be adopted in hybrid, plug-in hybrid, and pure electric vehicles (HEV, PHEV, and EV), where a bidirectional DC-DC converter (BDC) is used to connect batteries and ultra-capacitors. The efficiency improvement of the BDC is beneficial to increase the efficiency viability of HESS. Due to ZVS, high efficiency can be obtained at heavy load operations while the...

Ambient conditions can have a significant impact on the average and maximum temperature of the battery of electric and plug-in hybrid electric vehicles. Given the sensitivity of the ageing mechanisms of typical battery cells to temperature, a significant variability in battery lifetime has been reported with geographical location. In addition, high battery temperature and the associated cooling...

Employing plug-in electric vehicles (PEV) as energy buffers in a smart grid could contribute to improved power grid stability and facilitate the integration of renewable energies. While the technical feasibility of this concept termed vehicleto-grid (V2G) has been extensively demonstrated, economic concerns remain a crucial barrier for its implementation into practice. A common drawback of prev...

Due to demand for decreasing CO2 emission and improving fuel-efficiency of vehicles, research and development of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) is being revitalized worldwide. In advance of widespread use of EVs and PHEVs, Europe, United States and Japan have cooperated and worked on the international standardization of the vehicle charging system. We have ...

In view of the limitations of automated mechanical transmission (AMT) for plug-in hybrid electric vehicle (PHEV), as a scheme of new transmission system without synchronizer Electric-drive Automated Mechanical Transmission (EMT) was proposed. Taking use of the electric machines’ speed quick response characteristic, EMT uses active synchronous gearshift instead of the passive friction gearshift ...

The adaptive power management strategy is developed for a four-mode plug-in hybrid electric vehicle in this paper. For a given driving pattern, dynamic programming is employed to obtain the global optimum as the performance upper bound to benchmark the proposed strategy. A selforganizing fuzzy controller is used to adaptively adjust the equivalence factor for converting the electric power usage...

The electrification of transport systems requires a change in the composition vehicle fleet towards higher shares electric vehicles. A successful transition, however, depends on many factors which some relate to purchase prices and features, while others technology charging infrastructure. This paper analyses transition plug-in We use data from large representative Danish stated choice survey. ...
