BMW and Siemens in Berlin tested induction chargers (without cables)

BMW wants i8 load your future as if it were a mobile phone. The blue and white propeller has signed a collaboration agreement with Siemens to test a new system of charging by induction to be launched in May, four weeks before the official deployment in Berlin. It must be said that such systems are not completely new (there are several prototypes to test, and indeed the old GM EV1 was already using an induction charger), but the fact that BMW publicly bet induction is a remarkable story.

As the current wireless charging system for small electronic devices (such Powermat, or those who already use the center consoles of Audi), this device consists of a flat surface on which to leave the vehicle in question, and since the process load is performed using electromagnetic fields rather than using a typical cable, the risk of vandalism is reduced considerably.

Given its characteristics, BMW and Siemens indicate that their induction charging system could be easily installed in car parks and taxi ranks. Imagine for example that regulated parking areas in your city were equipped with this kind of boots, only to take a few coins in the meter (or pass your card RFID), and when returning from work, your car will be waiting for fully charged.

According to Siemens, the effectiveness of their chargers from the mains to the battery is over 90%, and the magnetic field, which largely met international safety measures, does not exceed the distance between the two coils used in the loading process .
