[0031] Disclosed herein is an energy conservator that can be used to conserve energy in a power source such as a direct current ("DC") battery. The battery is connected to the conservator which is in turn, connected to a load device. When the load device requires power, the battery discharges DC power which is then converted to alternating current ("AC") power by the conservator on its way to the load device. A portion of the AC power is converted back into DC power by the conservator and supplies power to three charging circuits.

[0032] The three charging circuits operate independently to send DC electricity back into the battery at different levels of current and at different rates and are controlled by a charging controller which has an internal logic (e.g. a timer switch) for controlling the circuits.

[0033] As a result of the operation of the energy conservator the discharge of the battery is smoothed out (i.e. charge-usage "spikes" from load devices are less severe) and the battery loses its capacity at a much slower rate, thereby conserving energy stored in the battery.

[0034] Referring to Figure 1 , the energy conservator environment is shown at 100 and consists of at least three main components. These components include a rechargeable battery 102, a charging unit 104 and an electrical load device 106. [0035] The rechargeable battery 102 is, for example, a 12 volt DC battery, however other rechargeable DC batteries 102 can be used with the present invention. The rechargeable battery 102 has an input attached to a conductor (e.g. wire) 110 as well as an output attached to a conductor (e.g. wire) 110. When the conservator is operating, the input receives DC electricity along the wire 110 from the charging unit. The battery 102 stores this charge to be used and/or discharged at a later time. When the electricity is discharged it flows through the output along the wire 110 to the conservator and/or load device 106.

[0036] The load device 106 may be any electrical or electro-mechanical load device that is at least partially receptive to electricity (i.e. partially operable by electricity). The load device 106 has an input attached to a wire 110. The input receives the electricity discharged from the battery along the wire 110 in order to (at least partially) power the load device 106. The electricity received into the input of the load device 106 from the wire 110 is preferably AC electricity. For example, the input may be a 110 to 220 AC volt pure sine wave as may be suitable for electrical devices or home appliances.

[0037] The charging unit 104 shown in Figure 1 and Figure 2 consists of an inverter 212, a transformer and filter regulator 210, three charging circuits 204, 206, 208 a charger regulator 214, a charging controller 216 and a relay circuit 220.

[0038] The inverter 212 is preferably a metal-oxide-semiconductor field-effect transistor ("MOSFET") with complementary metal-oxide-semiconductor ("CMOS") circuit logic. The inverter 212 receives the DC electricity as input and transforms the current into AC electricity. The inverter 212 then outputs the AC electricity downstream along a wire 110 (i.e. in the direction of arrow 222). The output from the inverter 212 may, for example, be a 110 to 220 AC volt square wave (i.e. non-sinusoidal waveform) output as shown in Figure 1.

[0039] The non-sinusoidal waveform output of the inverter 212 is then applied to a transformer and filter regulator 210. The transformer and filter regulator 210 steps up and adjusts the output to an AC sine waveform rate at 110 volts or 220 volts root mean squared. A person of ordinary skill in the art would understand that this rate of voltage is suitable for operating most conventional household appliances and electronics equipment. However, it is recognized that incorporating different types of transformer and filter regulators 210 can result in different rates of voltage as may be required by different load devices. [0040] A portion of this AC electricity supplies the charger regulator 214. This portion of AC electricity is received at the charger regulator 214 and is converted (or rectified) back into DC voltage and is output as such by the charger regulator 214. This DC electricity is output to one or more of the three charging circuits 204, 206, 208, for example.

[0041 ] The AC electricity output also supplies the load device 106. The load device 106 is connected via the wire 110 to the charging unit 104. A switch 118 is located on the wire 110 between the charging unit 104 and the load device 106. The switch 118 is operatively connected to the charging unit 104 to supply power to the load device 106.

[0042] Three charging circuits 204, 206, 208 can receive DC electricity from the charger regulator 214. The three charging circuits 204, 206, 208 are located in parallel downstream of the charger regulator 214.

[0043] The charger regulator 214 has three outputs connecting to conductive wires 110. The DC electricity resulting from the conversion (or rectification) performed by the charger regulator 214 is output into the three wires 110. Each wire 110 extending downstream from the charger regulator 214 connects to the input of a separate charging circuit 204, 206, 208. Single switches 218 are located on each of the three wires extending from the output of the charger regulator 214. These three switches 218 may be operated (i.e. opened or closed) independently of each other such that when any one (or more) switch 218 is closed electricity flows from the charger regulator 214 to the respective charging circuit along the wire on which the switch 218 is closed.

[0044] Each of the three charging circuits 204, 206, 208 has a separate output connected to a wire 110 which in turns leads to an input connection of the charging controller 216.

[0045] The charging controller 216 controls the operation of the switches 218 and therefore controls the flow of electricity from the charging unit 104 back to the battery 102. For example, the charging controller 216 sends a signal to any one or more of the switches 218 instructing the switch to open (or close) to prevent (or allow) electricity to flow along the respective wire 110 between the charger regulator 214 and the respective charging circuit. [0046] The first charging circuit 204 has an input that receives one corresponding wire 110 from the charger regulator 214. When the switch 218 on the corresponding wire 110 is closed, DC electricity flows from the charger regulator 214 to the first charging circuit 204. The second charging circuit 206 has an input that receives another corresponding wire 110 from the charger regulator 214. When the switch 218 on the corresponding wire 110 is closed, DC electricity flows from the charger regulator 214 to the second charging circuit 206. Similarly, the third charging circuit 208 also has an input that receives a corresponding wire 110 from the charger regulator 214. When the switch 218 on the corresponding wire 110 is closed, DC electricity flows from the charger regulator 214 to the third charging circuit 208.

[0047] When a particular switch 218 is closed, thus allowing electricity to flow along the wire 110 on the circuit, and when the battery is discharging electrical energy onto the wire 110 of the circuit, the corresponding charging circuit (i.e. 204, 206 or 208) is considered to be in charging mode. A charging circuit (i.e. 204, 206 or 208) is said to be "engaged" when its respective switch 218 is closed and "disengaged" when its respective switch 218 is open.

[0048] The first charging circuit 204 is a relatively low current rapid charging circuit and is normally in charging mode during operation of the conservator. For example, the first charging circuit 204 is the only charging circuit that always supplies a charge back to the battery 102 when the conservator is in charging mode (i.e. when the battery 102 is discharging electricity for the load device 106).

[0049] The second charging circuit 206 is a relatively high current slow charging circuit and is also normally in charging mode. The first charging circuit 204 therefore supplies a lower current charge at a faster rate as compared to the second charging circuit 206. Similarly, the second charging circuit 206 supplies a higher current charge at a slower rate as compared to the first charging circuit 204. The second charging circuit 206 is also shown in Figures 5 and 5B.

[0050] The function of the second charging circuit 206 is to at least partially compensate for the immediate loss of charge on the battery 102 when a load device 106 is receiving charge from the battery 102. When the load required by the load device 106 spikes, or has a relatively sharp load-demand increase for example, the second charging circuit 106 is engaged to at least partially compensate for the spike in the load. The result is that the spike in battery 102 usage is smoothed out. Such a spike in battery 102 charge usage may, for example, result from additional load devices 106 being connected to the battery 102 with the additional load devices 106 being charged from the battery 102. The second charging circuit 106 may be disconnected, for example, when the loss of charge from the battery 102 is at least partially replenished.

[0051 ] In a situation in which load devices 106 are connected or disconnected dynamically, the second charging circuit 206 is preferably engaged and disengaged as the load devices 106 are connected and disconnected, respectively. The second charging circuit 206 may therefore be used repeatedly but is not always providing a charge back to the battery 102.

[0052] The third charging circuit 208 provides electricity with a higher voltage than the other two charging circuits 204, 206. The third charging circuit 208 is preferably only used when additional load devices 106 are connected to the battery 102 so as to be charged by the battery 102. For example, there may be a threshold battery charge level, below which the third charging circuit 208 is engaged to supply charge back to the battery 102.

[0053] The three charging circuits 204, 206, 208 may be engaged or disengaged independently and if more than one charging circuit is engaged the resulting currents will simultaneously flow back to the battery 102.

[0054] Figure 7 is a block diagram showing the operative connections and components of the charging controller 216. The charging controller 216 has a memory 702 for storing data and instructions (e.g. computer code, circuit logic). A processor 700 is integrated with the charging controller 216 and is able to execute instructions stored on memory 702. The charging controller 216 is operatively connected to each of the circuit switches 218 as well as to a timer switch 704 in order to operate the switches. The main output switch 704 is located downstream from the charger controller. When the main output switch 704 is disengaged (i.e. the main output switch 704 is open) then no current can flow from the charging circuits 204, 206, 208 along the wire 110. When the main output switch 704 is engaged (i.e. the main output switch 704 is closed) then electric current is able to flow from the charging circuits 204, 206, 208 along the wire 110 to the battery 102 depending on whether the switches 218 are engaged. The instructions stored on memory 702 may dictate when the switches 218, 704 are to be closed and/or opened. The processor 700 then executes these instructions, closing and/or opening the switches 218, 704 when required by the instructions. The memory 702 also stores the threshold battery charge level for determining the charge below which the third charging circuit 208 will be engaged. [0055] A battery monitor 706 and/or a load monitor 708 can be connected to the charging controller 216. The battery monitor 706 is connected to the battery 102 and monitors the charge remaining on the battery 102. The battery monitor 706 relays this information to the charging controller 216. Similarly, the load monitor 708 monitors the electricity usage and requirements of the load device 106 and relays this information to the charging controller 216. The charging controller 216 uses the inputs gathered from the load monitor 708 and battery monitor 706 together with the instructions stored on memory 702 to operate the switches 218, 704 in order to provide electrical charge to the battery 102.

[0056] Alternatively, there may be no load monitor 708 so that the only monitor connected to the charging controller 218 is a battery monitor 706. In such a situation, the charging controller 216 uses the input gathered from the battery monitor 706 together with the instructions stored on memory 702 to operate the switches 218, 704 in order to provide electrical charge to the battery 102.

[0057] The charging controller 216 monitors the battery charge using the battery monitor 706 and by operating the switches 218, 704, provides that 15% (or some other predefined charge portion) of the battery charge is continuously routed through at least one of the circuits 204, 206, 208 back into the battery.

[0058] The first circuit 204 is continuously on or closed (i.e. allowing electricity to flow through the circuit 204 back to the battery) in order to address the loss of the electricity on the line or wire 110.

[0059] The memory 702 maintains two or more threshold values to assist the charging controller 216 with the operation of the circuits 204, 206, 208. The threshold values may be one of the following values: voltage of the battery, current of the battery, load draw, rate of change of voltage of the battery, rate of change of current of the battery, rate of change of load draw, or any combination of the above. The battery monitor 706 and/or load monitor 708 measures these same metrics and relays them to the charging controller 216, which compares the monitored measures with the threshold values.

[0060] If the monitored value is greater than the first threshold value stored in memory 702 then the second circuit 206 is engaged (i.e. electricity flows through the second circuit to the battery). If the monitored value is greater than the second threshold value stored in memory 702 then the third circuit 208 is engaged (i.e. electricity flows through the third circuit to the battery).

[0061 ] It is recognized that the charging controller 216 may be software, hardware, firmware or a combination of the three.

[0062] A relay 220 receives at its input the electrical charge that is output from the charging controller 216. The relay 220 is operatively connected to the terminals of the battery 102 so that it can monitor the terminal voltage of the battery. If the terminal voltage of the battery 102 is lower than a threshold voltage maintained by the relay 220 then the output from the charging controller 216 is relayed to the battery 102 so that the battery 102 may be charged. However, if the terminal voltage of the battery 102 is higher than the threshold voltage then the relay disengages the charging process by disengaging the switch 108 (see Figure 2). Similarly, when the battery is in an overcharged state or when only small loads are connected and charging is not desired, then the relay disengages the charging process. The relay 220, therefore, automatically determines whether the battery 102 is overcharged and if so the relay 220 prohibits electricity to flow from the charging circuits 204, 206, 208 to the battery 102.

[0063] The rechargeable battery 102 is attached to relay 220 (and thus the charging unit 104) via a conductive wire 110, forming a closed circuit (as shown in Figure 2). The conductive wire 110 may, for example be a copper wire or electrical wiring or may be constructed from other suitable conductive material including aluminum.

[0064] The three charging circuits 204, 206, 208 provide different functions and are independently controlled by the charging controller 216. The second charging circuit 206 supplies a high current charge at a slower rate as compared to the first charging circuit 204 to compensate for the immediate loss of charge on the battery when there is at least one load device 106 connected to the conservator. The third charging circuit 208 provides the highest voltage which may be needed as a back-up to boost the charging process when additional loads are connected to the conservator.

[0065] The logic of the charging controller 216 (including instructions that may be stored on memory 702) will now be described in more detail with reference to Figure 8. [0066] First, at step 802, the charging controller 216 is turned on and the battery monitor 706 reads the voltage of the battery. At step 804 the first charging circuit 204 is engaged. The first charging circuit 204 addresses charge lost due to internal losses on the battery itself, the inverter, and the voltage regulator. At step 806, the load is connected to the conservator. A load monitor 708 may be connected to the load device 106 in order to monitor the charge required by the load device 106. If an additional load device 106 is attached to the battery 102 and/or conservator then the charging controller 216 may receives further information from the load monitor 708 regarding the second load device106.

[0067] At step 810 the processor compares the voltage of the battery (as provided by the battery monitor 706) to the first threshold level 818. If the voltage of the battery is lower than the first threshold level 818 then the second circuit 206 is engaged 812 and the second circuit switch is engaged 816 allowing electricity to flow back to the battery from the second circuit 206. Otherwise the second circuit switch is disengaged 814.

[0068] Similarly, at step 818 the processor compares the voltage of the battery (as provided by the battery monitor 706) to the second threshold level 818. If the voltage of the battery is lower than the second threshold level 818 then the third circuit 208 is engaged and the third circuit switch is engaged 822 allowing electricity to flow back to the battery from the third circuit 208. Otherwise the third circuit switch is disengaged 820.

[0069] At step 824 the relay 220 determines whether the battery 102 is overcharged and if so 828, the switch 108 is disengaged (i.e. disengaging the conservator); if not 826 then the switch 108 is engaged (i.e. allowing electricity to flow to the battery 102 from the any engaged charging circuits 204, 206, 208)

[0070] For example, in the table below, if we have a load of 100 amps, the AVR with a turn ration of 10 will draw 10 amps. In turn the inverter will draw 10 amps also from the battery, hence the battery will need 10 amps for recharging which will be supplied by the charging circuits once detected by the relay circuit. The transformerless power supply will only need 100 milliamps to operate the charging system. The charging circuits will only supply the needed amperes lost by the battery, in this case 10 amps. The below example is based on load only, without considering the power loss on both the inverter and the AVR. Battery Inverter AVR Load, Amperes Charger

[0071] It is recognized that other batteries having different voltages can be connected and used with the energy conservator in the manner described above.

[0072] In one embodiment, the energy conservator is be connected to a separate power source providing electrical input to the charging unit 104 to be sent to the load device 106. The output of the charging unit 104 (i.e. the "conserved electricity") is then sent from the charging unit 104 to a separate battery 102 for recharging.

[0073] Although specific embodiments of the invention have been described herein, it will be understood by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
