DETAILED DESCRIPTION OF THE DRAWINGS

[0065] FIG. 1 schematically illustrates a particular application of a generator unit of the present invention integrated within a vehicle (1). MPPT controller, inverter and AC charger (8) are in direct communication with the generator unit (10), through which the generator unit (10) is fed with energy collected with different collectors. Solar panels (4), appropriately installed and or hidden in the vehicle (1), turbine winds (5) and PMG generators (7) are connected to the MPPT controller (8) that controls the flow of energy from them to the generator unit (10) and to the main battery (2). PMG generators (7) are installed on the axles (9) between each pair of wheels (6), moving in concert with the movement of the wheels and translating their kinetic energy to electrical current, which then flows to the generator unit (10) through the inside inverter/controller (20) as shown in FIG. 2. The output of the generator unit (10) communicates with the main battery (2), recharging it with the power generated. The communication between the generator unit (10) and the main battery (2) is controlled with a clutch that activates recharging when the vehicle is in parked state or when the capacity of the main battery (2) is low.

[0066] FIG. 2 illustrates a particular type of generator unit (10) that may be integrated within any electrically operated application for recharging main battery (2) as shown in FIG. 1. The generator unit (10) for the recharging of main battery (2) (see FIG. 1) comprises: supplemental batteries (22) powering electric motor (12) that drives electromagnetic generator (16) via a pulley arrangement comprising a belt (14). DC motor (15) is used to operate the motor and cooler (13) expels extra heat generated in the operation of the motor (12). Automatic regulator (26) adjusts the supply for the motor voltage (12). Supplemental batteries (22) are charged and recharged from energy sources external and internal to the application, natural, electrical or recycled (as shown in FIG. 1), and output current to motor (12), which then powers generator (16). The current generated by the generator (16) flows to the controller (20) at a current speed determined by rotation speed (18), and from there it recharges main battery (2) (shown in FIG. 1). The charge in supplemental batteries (22) flows through switching and measuring means (24) that monitor and redirect the current flow to and from the current converter/inverter (20), which will supply output to the main battery (2). The converted current enters a transformer equipped with an automatic regulator (Variac) before it enters the main battery (2).

[0067] Electric sockets (28) fitted onto the current converter/inverter (20) can be used to discharge batteries (22) back to the grid and be credited for the extra power provided to the electricity company. Otherwise, the converter/inverter (20) continues to stream current to the main battery (2) to recharge it.

[0068] For generator unit (10) connected to electrical applications, appliances, machines or devices and viewable to a user, as shown in FIG. 3, the current converter/inverter (20) comprises: a screen (36) displaying battery power (30), an ON/OFF switch (32), which turns the unit on and off and a button (34), which supplies voltages from 0 to 230 volts through the socket (28).

[0069] When the start up of the generator unit (10) for recharging a main battery is required, the current converter/inverter (20) is turned on. The current converter/inverter (20) receives electrical current from the supplemental batteries (22). The current flows through the current switching and measuring systems (24), through the transformer and on into the motor (12) which then rotates. As in the example in FIG. 2, the motor (12) drives the generator (16) to which it is permanently connected and which generates current that recharges main battery (2) and eventually operates a load fed from the main battery (2), e.g. motor of a vehicle, electrically based system in a vehicle such as air-conditioning, electrical windows, fan etc.

[0070] The connection between the motor and the generator can be made using belts, gear wheels or using a direct mechanical connection.

[0071] Finally, FIG. 4 illustrates schematics (11) of a generator unit of the present invention connected to an electricity grid (44). This particular configuration illustrates the two modes of recharging and discharging main battery (2) of any electric device or machine from and to the grid (44), respectively. The recharging mode shows that the battery (2) is recharged directly from the grid (44) through relay box (40) and AC charger (38). Motor (3) activates controller (42) that monitors the charging state of the battery (2) and controls its capacity. Accordingly, the controller may be set to stop recharging upon reaching maximum capacity of the battery (2). In the reverse mode of discharging, the main battery (2) is indirectly discharged to the grid (44) through reverse action in generator unit (10) through converter/inverter (20) and DC motor (12) (shown in FIG. 2), which is in electric communication with the grid (44). Motor (3) activates controller (42) that switches to discharge mode and initiates command to depleting battery (2) through generator unit (10). Controller (42) also controls and monitors the minimum depletion state of the battery (2) and stops discharging when minimum charge to be kept in the battery (2) is reached.

[0072] In view of the illustration in FIG. 4, the present invention provides a method of discharging the main rechargeable battery (2) of partially or entirely electrically operated machine, device, application or appliance to an electricity grid (44) that comprises: [0073] 1. operating the motor (3) of the machine, device, application or appliance; [0074] 2. activating controller (42) of the machine, device, application or appliance with the motor (3), where the controller (42) is in electric communication with the motor (3); [0075] 3. discharging the main battery (2) of the machine, device, application or appliance through DC-AC-DC converter/inverter (20) in the generator unit (10), where the generator unit (10) is in electric communication with the main battery (2); [0076] 4. activating DC motor (12) of the generator unit (10), where the DC motor (12) is in electric communication with the electricity grid (44); [0077] 5. activating the controller (42) to monitor discharging of the main battery (3); and [0078] 6. activating the controller (42) to stop discharging of the main battery (2) upon reaching minimum charge state in the main battery (2).

[0079] Although selected embodiments of the present invention have been shown and described, it is to be understood the present invention is not limited to the described embodiments. Instead, it is to be appreciated that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and the equivalents thereof.
