NOVELTY - The apparatus has positive output electrode that is relative to rotating shaft (204). A negative output electrode is operable for selective electrical communication with battery cell negative terminal. A rotor (212) has electrically conductive portionwith inner diameter conductive connection surface and outer diameter conductive connection surface. The negative output electrode is relative to the rotating shaft. A connection system has brushes that electrically connect the rotor conductive connection surfaces or battery terminals with the output electrodes.    USE - Apparatus for providing homopolar generator charger with integral rechargeable battery, used in wind energy harnessing, automotive electric vehicle industry, geothermal system, hydropower, tidal and wave energy harnessing, uninterruptable power supply and emergency power.    ADVANTAGE - The rotational shaft carries the high currents without overheating. The output brushesplaced in close proximity to the rotor shaft of the homopolar generator chargerreduces friction. Thus the power efficiency can be improved. The brushes avoid the need of shielding so as to prevent the unwanted forces. The homopolar generator charger can be designed with low weight, and high efficiency. The homopolar generator charger can be operated under light loads or cruising speeds. The energy conversion can be utilized in an efficient manner. Thus maximum currents can be provided for charging the battery cells.
