Abstract: A system for supplying electrical energy to an energy-absorber mobile device having two electrically conductive secondary terminals includes a power-source base with electrically conductive primary terminals configured to be arranged in contact with the two secondary terminals when the mobile device is positioned on the base; a supply and control subsystem having a line selector whose outputs are connected to the primary terminals, a rectifier and programmable power supply providing energy, and a mini-processor connected to the line selector and to the rectifier and programmable power supply. The line selector has two input lines, between which a voltage difference higher than zero is applied and which is configured to apply the voltage difference cyclically to all possible pairs of output lines based on the commands received from the mini-processor.

Abstract: A charging apparatus for electrically charging rechargeable battery cells (2) of a mobile consumer (1) comprises a plurality of area-wise distributed primary contacts (3) which are insulated against each other and are connectable with at least two counter contacts (4), wherein the primary contacts (3) are connected with a control unit (5) and electrical switches (6) for wiring into a right polarity for the charging process.
