1. A system for supplying electrical energy to an energy-absorber mobile device (900; 1000) comprising two electrically conductive secondary terminals (802), said system comprising:
a power-source base (100) having a plurality of electrically conductive primary terminals (101), positioned on an upper surface of said base (100) and separated by electrically non-conductive materials (102), said primary terminals (101) being configured to be arranged in contact with said two secondary terminals (802) when said mobile device (900; 1000) is positioned on said base (100);
a supply and control subsystem (700) comprising a line selector (702) whose output lines (701) are connected to said primary terminals (101), a rectifier and programmable power supply (703) which supplies energy, and a mini-processor (704) connected to said line selector (702) and to said rectifier and programmable power supply (703) for exchange of data and commands,
wherein said line selector (702) has two input lines (705) between which a voltage difference higher than zero is applied and which is configured to apply said voltage difference cyclically to all possible pairs of said output lines (701) and, consequently, to corresponding pairs of primary terminals, based on said commands received from said mini-processor (704), and
wherein said supply and control subsystem (700) is configured to:
apply said voltage difference to said pairs of said output lines (701) until detecting that two primary terminals (101) of the corresponding pair are connected to said two secondary terminals (802), hence are identified, and
apply to said two primary terminals (101) a working voltage different than said voltage difference.
