  New Tech Making Electric Cars A Lot Easier to Use                                                                                           Source:  WiTricity New Global Standard Operating an electric car is about to get a lot easier.  New technology has been developed that allows a driver to charge their EV without plugging into an outlet.  The baseline technology has been developed by WiTricity, an MIT spin-off company that designs wireless charging for vehicles and appliances.  Automakers and suppliers have signed on to developing it as a universal standard.  Luxury vehicles like the BMW53oe hybrid are ready to use the system with moderately priced EVs expected to follow suit. Pad and Receiver The wireless power transfer (WPT) system is composed of a pad and a receiver.  The system delivers DC current from a pad mounted on the floor to a receiver on the vehicle.  Charging efficiency is 94%.  The SAE International engineers' association has brought in a large,  number of automa

Dubai's Electric Experiment Source:  Dubai Wireless Charging on the Move Dubai is testing electric buses that can pick up charging while on the move.  The dynamic wireless charging unit is embedded in a 60 meter stretch of roadway in the city.  It uses a new technology called "shaped magnetic field in resonance (SMFR). The result is seamless charging of the electric bus without it having to stop at a charging station.  What's fascinating is the system can be used for personal transportation like an electric car as well as public transportation like electric buses. Electrified Roads and Electrified Vehicles This new technology is designed to overcome battery limitations of range, cost of charging and finding a location to charge the vehicle. The SMFR embedded road system activates when a sensor picks up that an electric vehicle is driving over it.  A pickup coil is attached to the underbody of the EV to make the connection work and the charge flow into the
