Reducing CO2 emissions in transportation systems: technologies for electric vehicles powering

This paper illustrates innovative transport systems for the power supply of electric vehicles as a replacement for the plug-in system. Different technologies for energy transfer are being developed worldwide: three of them are more mature, but other may come. Nowadays, the mainly three systems under development are the following: overhead cable power supply system, ground contact power supply system and the contactless wireless charging methodology using the Dynamic Wireless Power Transfer system.
