This paper presents the user-friendly plug-andcharge mechanism defined in the ISO/IEC 15118 standard which enables an automatic authentication, authorisation, and billing procedure during the charging process of an electric vehicle. The various certificates, their application in a public key infrastructure as well as the interplay with a clearing house are explained – illustrated using the Germ...

Battery chargers are essential components for further development of plug-in vehicles including electric or hybrid electric vehicles. The 3.3kW battery charges are widely used in plug-in vehicles in which the power source is the single phase ac grid. The auto industry has stringent requirements on the size, efficiency, temperature and packaging of the onboard chargers that are reviewed in this ...

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...

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 ...
