Patent ID: 7989980

Claim:
A portable self-regenerating power system ( 8 ) that produces AC power and stores DC power for supplying electricity to tools and devices at work sites, that is configured to be electrically connected to a vehicle, wherein the vehicle includes a vehicle alternator, a battery, an engine, and a starting system, the portable self-regenerating power system ( 8 ) comprising: a) a box ( 28 ) mountable on the vehicle for housing the portable self-regenerating power system ( 8 ) and having additional space for storage, the box ( 28 ) containing a DC control panel ( 22 ), a DC to AC inverter ( 10 ), a second battery ( 14 ), an on/off key switch ( 12 ) and a timer ( 16 ); b) the DC control panel ( 22 ) electrically connecting the second battery ( 14 ), the DC to AC inverter ( 10 ), the on/off key switch ( 12 ) and the timer ( 16 ), the DC control panel ( 22 ) further comprising a DC output ( 18 ) for supplying the devices with DC power; c) an energy collecting solar panel ( 40 ) for charging the second battery ( 14 ), d) the on/off key switch ( 12 ) and timer ( 16 ) is mounted on the DC control panel ( 22 ) and is configured to electrically connect the first battery and the starting system to start and run the engine for a predetermined time in order to recharge the second battery ( 14 ) from the vehicle alternator, and stop the engine after the second battery ( 14 ) is recharged; e) the DC to AC inverter ( 10 ) comprising AC power outlets ( 26 ) for supplying AC power to the tools from the DC to AC inverter ( 10 ), the second battery ( 14 ) and the alternator; f) the box ( 28 ) housing the portable self-regenerating power system ( 8 ) is configured to electrically connect to the vehicle alternator and the first battery which operates under the control of the on/off key switch ( 12 ) and timer ( 16 ) to energize the DC control panel ( 22 ), the DC to AC inverter ( 10 ) and the second battery ( 14 ) to supply power through the DC to AC inverter ( 10 ), and to recharge the second battery ( 14 ) to store power to be used when the vehicle is not running.
