Technology wireless charging of mobile devices gradually come to a common denominator and standard. Automakers are beginning to integrate wireless charging device for smart phones in the vicinity of the front of the vehicles. Meanwhile, searching for an alternative to machines hydrocarbon fuels, producers increasingly look for hybrid or electric systems, which require daily recharging. To facilitate this process and make it transparent, manufacturers are thinking about implementing a wireless charging method of traction batteries.
This can not be called a new idea, but it concerns BMW and Daimler are trying to implement wireless charging technology of hybrid and electric vehicles. Existing prototypes that BMW tests on their models i8 (rechargeable hybrid) and i3 (with optional electric "xtension course based on ICE) allows wirelessly transmit up to 3.6 kW of power through two loops placed underneath the car and supporting surface respectively. BMW claims that the charger has an efficiency of at least 90%, and the presence of snow or water on the support surface does not interfere with work.
Opportunities such charger should be enough to recharge the battery in a hybrid car two or three hours. According to the developers, if necessary transmit power can be increased to 7 kW, and it will allow for faster charging electric cars that rely only on batteries as a power source.
For efficient operation of the charger circuits has to be aligned one above the other with sufficient accuracy, so the car and built-in garage floor will exchange coordinates wirelessly WiFi. If we consider that an automatic parking system is implemented on a production car, the positioning process can be without human intervention. Control the charging process can be remotely via smartphone. A variation of this system can be considered complex chargers for public electric, which allows you to charge batteries at stops while going embarkation and disembarkation of passengers.
