[0020] As shown in the accompanying drawings, for illustrative purposes, the present invention is directed to an electric power generation system that can be used to power one or more electric devices, including electric vehicles.
[0021] refer to Figure 1 , an electric power generation system, generally indicated by reference numeral 100, has an electric power input source, typically including a plurality of batteries 102. Figure 1 As shown, the batteries 102 are electrically coupled together in series. Although the number of batteries can vary, twelve batteries are shown electrically interconnected to each other by wires to form a first group of batteries 102. The positive terminal of one battery is electrically connected to the negative terminal of an adjacent battery to connect the batteries 102 into an electrical series.
[0022] The negative terminals 104 and positive terminals 106 of the end cells of the battery pack 102, or the net accumulated voltage or charge of the battery pack 102, are connected to a first controller 108. More specifically, the negative terminal 104 is interconnected to a negative terminal 110 of the controller, and the positive terminal 106 of the battery pack 102 is connected to a positive input 112 of the controller 108. As will be explained in more detail below, the first controller 108 has outputs 114 and 116 that are electrically coupled to the power generator of the system 100. A second controller 118 may be in electrical communication with the first controller 108 via wires extending from the outputs 120 and 122. The second controller 118 may assist the first controller 108 in operating the power generator. Using the second controller 118 in conjunction with the first controller 108 is believed to reduce the amperage used by the motor that runs the power generator.
[0023] like Figure 1 The illustrated electrical generator 124 is comprised of a series of interconnected motors. A first motor, which may be described as a drive motor 126, is electrically coupled to the first controller 108. More specifically, the negative output 114 of the controller 108 is electrically coupled to the negative terminal of the first motor 126. A shaft 128 of the first motor 126 extends from a head H of the first motor 126 and is rotatably coupled to a shaft 130 of an end motor 132 in a motor chain 132-140. Although the motor chain 132-140 is shown as five interconnected motors, it is understood that the number of interconnected motors may vary. The shaft 130 extends from the head H of the end motor 132. The shafts 128 and 130 are coupled to each other, such as by a belt or chain 142 or a flywheel. Thus, the heads H of the motors 126 and 132 are interconnected. The motors 126 and 132 are electrically connected to each other, such as the positive terminal of the motor 126 is connected to the negative terminal of the motor 132, as shown.
[0024] The motors in the motor chains 132-140 are also electrically coupled to each other, such as in series. As shown, the positive terminal 116 of the output controller 108 is electrically coupled to the positive terminal of the motor 134. The positive terminal of the motor 132 is electrically coupled to the negative terminal of the adjacent motor 134. Similarly, the positive terminal of the motor 134 is electrically coupled to the negative terminal of the adjacent motor 136. The positive terminal of the motor 136 is electrically coupled to the negative terminal of the adjacent motor 138, and so on. In addition, the controller 108 is electrically coupled to at least one of the motors in the motor chains 132-140, Figure 1 In the embodiment shown in , the positive output terminal 116 of the controller 108 is electrically coupled to the positive terminal of the motor 134 , which is the middle motor in the motor chain 132 - 140 .
[0025] As shown, the motors of the motor chain 132-140 are also physically interconnected with each other. The tail T of the motor 132 is coupled to the head H of the motor 134. This head H to tail T adjacent motor connection runs through the entire motor chain 132-140. More specifically, the shafts extending from the tail T and the head H of the adjacent motors are interconnected with each other. This is usually achieved by a flywheel assembly 144 placed between adjacent motors in the adjacent motor chain 132-140. The flywheel assembly 144 includes a first disk 146 fixed to the shaft 148 of the motor, such as fixed to the tail shaft 148 of the motor 132, and a second disk 150 fixed to the shaft 152 of the adjacent motor, which is fixed to the head shaft 152 of the motor 134 in the embodiment shown in the figure. The first and second disks 146 and 150 are interconnected with each other, such as by one or more bolts 154 or the like. Similar flywheel assemblies are placed between adjacent motors of the remaining motor chains, wherein the shafts of the tail T and the head H are interconnected with each other.
[0026] Reference now Figure 2 , the motor arrangement of the motor chain can be varied and achieve the same function or purpose, or even better results. For example, a gear assembly 156 can be used instead of a flywheel assembly 134 placed between adjacent motors to interconnect the shafts of adjacent motors. The gear assembly 156 can include first and second gears 158 and 160, which are operatively coupled to their respective motor shafts. For example, the gears 158 and 160 can have a gear ratio of 2:1. Ideally, the smaller gear 160 would be connected to the head shaft and the larger gear 150 would be connected to the tail shaft of the adjacent motor. This can increase the speed of the motor downstream of the gear assembly 156 to generate more power.
[0027] The electricity generated by the power generator 124 may be delivered to an inverter 162, which receives the DC power and converts it to AC power for use by one or more power devices 164. The outlet 166 may be used to selectively power one or more power devices 164 on or off.
[0028] Reference now Figure 3 , showing the Figure 1 A similar system 100 is shown. However, in this embodiment, a second set of batteries 168 is provided. The second set of batteries 168 is similar to the first set 102, i.e., there are multiple batteries electrically coupled together in series, as shown. Again, although twelve batteries are shown in each set 102 and 168, the number of batteries can be less or more than this number as needed or desired. The present invention contemplates that one set of batteries 102 or 168 can be used to power the system 100, while the other set 102 or 168 can be used for backup and / or charging. Switches S1-S4 can be incorporated into the system 100 to achieve this purpose.
[0029] For example, a pair of switches interconnecting one set of batteries 102 or 168 to the controller 108 can be closed so that power is provided by another set of batteries 102 or 168 for use by the controller 108 and the power generator 124. The other set of batteries 102 or 168 can be charged, including using power generated by the power generator 124. For example, switches S1 and S3 can be closed so that the system receives power from the second set of batteries 168, such as through switch S2, while power output through switch S4 is input into the first set of batteries 102. To power the system from the first set of batteries 102 and charge the second set of batteries 168, switches S2 and S4 can be closed, with switch S1 powering the system while switch S3 delivers power from the power generator 124 to the second set of batteries 168. Rather than directing power from the power generator 124 to one set of batteries 102 or 168, power can be directed to one or more power devices 164, as described above.
[0030] Reference now Figure 4 , shows an electric power generation system 100 embodying the present invention, which is similar to the above-mentioned Figure 1The system 100 includes a set of batteries 102 that are electrically coupled to each other and to a first controller 108 for powering an electric generator, including a plurality of motors 126-140 as described above. However, in this case, a capacitor 170 is also integrated into the system 100. The capacitor 170 is charged by the power generated by the electric generator 124. A diode and a switch 172 may be used to direct power from the motor of the electric generator to the capacitor 170. However, the power of the charged capacitor 170 may be used to power an electric device, such as a vehicle motor 174, or even charge the battery pack 102, such as by activating a diode and a switch 176. When the diode and the switch 176 are closed, the power of the capacitor 170 may be directed to an electric device, which may include a DC vehicle motor 174, through a second controller 118. In this case, the first controller 108 provides energy to the capacitor through the electric generator 124, and the second controller 118 is used to run and operate the vehicle motor 174. The present invention also contemplates the possibility of switched conductors that can provide power from the motors of the electric generators 126-140 to the battery 102 to charge the battery, or to the vehicle motor 174. The previously charged capacitor 170 can provide power to the battery pack 102 to recharge, or to the vehicle motor 174 when the vehicle is running.
[0031] Reference now Figure 5 , shows an electric power generation system 100 embodying the present invention, the system integrating Figure 1 and Figure 4 As described above, a plurality of batteries 102 are electrically interconnected in series to power a first controller 108, which in turn powers a plurality of motors that make up an electric generator 124. The power output of the electric generator may be directed to an inverter 162, which converts direct current into alternating current for use by one or more electrical devices 164. The power may also be directed to a capacitor 170 for use, for example, Figure 4 In this case, power may be transferred from the capacitor 170 to the vehicle motor 174 via the second controller 118 as needed. When the vehicle motor 174 is not running or not drawing full power from the capacitor 170, the capacitor is charged by the motor 126-140 of the power generator. As described above, the present invention contemplates that the capacitor 170 may also be used to recharge the first set of batteries 102 by providing a conductor between the capacitor 170 and the battery 102 (if necessary).
[0032] It should be understood that Figure 1 and 3 The arrangement of the motor chains 132-140 shown in Figure 5 can have different configurations, for example Figure 2In the embodiment, a gear assembly 156 is used instead of a flywheel assembly 144 between adjacent motors in the motor chain. In addition, as described above, the number of motors in the motor chain can be varied as needed or desired.
[0033] Reference now Figure 6 , the electric vehicle motor 174 may have a shaft 178 connected to a disc assembly 180 by a coupling 182 and a pin 184, so that when the shaft 178 rotates, the attached disc assembly 180 will also rotate. The disc assembly 180 is composed of two discs 186 and 188, which are interconnected to each other, such as by one or more bolts 190. A sprocket 192 of a first diameter is coupled to the disc assembly 180 by a tube 196 or bolts, and can rotate freely relative to the shaft 194, and the sprocket 192 rotates with the disc assembly 180.
[0034] The first sprocket 192 is rotationally coupled to a second sprocket 196 of a different, typically larger diameter, via a belt or chain 198. This rotational coupling may be achieved via the belt or chain 198. A crankshaft 200 is connected to the second sprocket 196, such as via a shaft 202. The crankshaft 200 includes counterweights 204 spaced along the length of the shaft 202, located at a distance from the centerline of the shaft 202, to produce leverage and torque. The degree of leverage and torque may depend on the weight of the counterweights 204 and the distance of the counterweights 204 from the centerline 202. The heavier the counterweights 204 and the farther away they are, the greater the torque and leverage provided. The counterweights 204 are staggered from one another, such as Figure 6 shown.
[0035] The rotational energy and motion of crankshaft 200 is transferred to a flywheel-clutch assembly 206, which includes a clutch 208 and a flywheel 210. The assembly 206 transfers the rotational energy, such as through a gearbox 212, to one or more wheels or tires 214 as desired.
[0036] Although several embodiments have been described in detail for purposes of illustration, various modifications may be made without departing from the scope and spirit of the invention. Therefore, the invention should not be limited except as in the appended claims.
