1. A power transfer system for exchanging electric power between an electric power system and a battery of an electric vehicle comprising:
a transmitter-side power sub-system electrically coupleable with said electric power system and adapted to exchange AC electric power with said electric power system;
a transmitter-side coil sub-system electrically coupled with said transmitter-side power sub-system and adapted to exchange AC electric power with said transmitter-side power sub-system, said transmitter-side coil sub-system comprising a transmitter coil;
a receiver-side coil sub-system comprising a receiver coil inductively coupleable with said transmitter coil, said receiver-side coil sub-system being adapted to exchange AC electric power with said transmitter-side coil sub-system;
a receiver-side power sub-system electrically coupled with said receiver-side coil sub-system and adapted to exchange AC electric power with said receiver-side coil sub-system, said receiver-side power sub-system being electrically coupleable with said battery and adapted to exchange DC electric power with said battery;
first control means adapted to control operation of said transmitter-side power sub-system;
second control means adapted to control operation of said transmitter-side coil sub-system;
third control means adapted to control operation of said receiver-side coil sub-system and receiver-side power sub-system;
a first communication channel of the wireless type between said first and third control means; and
a second communication channel and a third communication channel between said first and second control means, said first and second control means being adapted to assign higher priority to data and/or commands exchanged through said second communication channel with respect to data and/or commands exchanged through said first communication channel and/or through said third communication channel.
