Using thin-films of iron oxide as the active material of electrodes, supercapacitors are fabricated on various substrates in different shapes. By chemical oxidation the iron-oxide film is formed directly and conformably on the substrates in a short period ...

The system has two on-board electrical systems with different voltage levels and correspondingly two batteries (1a,20a), whereby each electrical system has an associated current distributor (1,20) and different loads (5,8,27,28,33) are associated with the ...

The method involves comparing the battery current (IBatt) in the motor vehicle with a desired current value (ISoll), feeding the determined difference signal to a regulator (2) and using the regulator output signal (PK) to influence the power made availabl...

An apparatus for and method of managing and distributing power from a supply of limited of power is described. A plurality of outlets (68, 70) are connected to a plurality of power units (114). As additional outlets are used, the invention measures the amo...
