Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
A wireless electric vehicle (EV) battery charger contains two units: a
primary unit and a secondary unit. The charger conducts grid-to-vehicle or vehicle-t-
-grid power transmission by using a magnetic link. In general, the two units of the
aforementioned charger communicate through radiofrequency communication
technology, such as Bluetooth or Wi-Fi. The data transferred in such communication
include the EV’s identification number, battery status, and active control commands.
The use of communication devices results in increased costs. Moreover, radiofrequency
communication is associated with signal interference and low real-time performance.
This chapter proposes a method for coherent wireless power and data transfer. The
method includes handshaking communication, current trimming, and the attachment of
data to modulated digital data by using a magnetic link. This method also supports the
transmission of real-time messages from the secondary unit through a carry wave.
