Abstract
Description
[0001] introduce
[0002] The information provided in this section is intended to generally present the background of this disclosure. The work of the inventors listed herein (within the scope described in this section) and aspects of the specification that may otherwise not be considered prior art at the time of filing are neither expressly nor implied to be prior art to this disclosure.
[0003] This disclosure generally relates to power distribution systems for charging batteries. For example, electric vehicles include batteries for powering motors to drive the vehicle and vehicle electrical components such as headunits, lights, air conditioning, etc. Some electric vehicles include one or more discharge ports that a user can use to power personal electrical devices such as cellular phones and tablets.
[0004] The electric vehicle also includes a charging port for receiving power from a charger coupled to a public power station to charge the battery. The charging port can be configured to accept 120-volt or 240-volt alternating current (“AC”). The charging power is regulated and controlled by an on-board charging control module (“OBCM”). Currently, when the battery is being charged, the OBCM disconnects power to the discharge port in the electric vehicle to facilitate regulation and control of the power supplied to the battery when the charger is plugged into the charging port.
[0005] Many electrical devices that can be plugged into a vehicle's discharge port are configured to receive 120-volt AC power. Therefore, directly plugging such electrical devices into a charger that receives power from a 240-volt source may damage the devices. Furthermore, such electrical devices can be configured to operate using power with different waveforms.
[0006] Therefore, a power distribution system is required, wherein a discharge port is operable for distributing power while the battery is charging. A power distribution device is also required, configured to increase or decrease the power from the power source to supply power to predetermined electrical equipment. Furthermore, the waveform of the power supply needs to be adjusted to suit the predetermined electrical equipment. Summary of the Invention
[0007] One aspect of this disclosure provides a power control system for supplying power from a first power source to a load and a battery. The first power source is configured to transmit power in alternating current (AC). The power control system includes an on-board charging control module and a splitter module. The on-board charging module includes a first processing unit configured to process the power from the first power source to charge the battery. The splitter module is located between the first power source and the on-board charging control module. The splitter module is configured to direct power from the first power source to the load. For example, the splitter module may be configured to supply power to a discharge port that the load can couple to. Therefore, while charging the battery, power can be supplied to the load.
[0008] Embodiments of this disclosure include one or more of the following optional features. In some embodiments, the splitter module includes an AC-AC converter configured to regulate power from a first power source.
[0009] In some examples, the on-board charging control module can be configured to provide electrical isolation between the load and the battery.
[0010] In some configurations, the splitter module can be configured to change the voltage of the power supply. For example, the splitter module can be configured to increase or decrease the voltage.
[0011] In some implementations, the splitter module may include various configurations. For example, the splitter module may include a sensing unit configured to measure the value of at least one of current and voltage, and / or the splitter module may include a switch operable to bypass or engage the AC-AC converter. Furthermore, the splitter module may include a second processing unit that receives a measurement of at least one of the current and voltage to actuate the switch.
[0012] In some configurations, the second processing unit may also be configured to actuate the AC-AC converter to generate a predetermined waveform. For example, the first processing unit of the on-board charging control module may be configured to transmit battery charging information to the second processing unit of the AC-AC converter, wherein the second processing unit processes the charging information to control the switch and maintain the desired waveform.
[0013] In some configurations, the AC-AC converter illustratively includes one of a buck converter, a buck-boost converter, and a single-ended primary inductor converter.
[0014] In some configurations, the on-board charging control module and the splitter module are integrated into a single module.
[0015] Another aspect of this disclosure provides an electric vehicle including a battery, a charging port, and a discharging port. The battery is configured to supply power to drive the electric vehicle. The charging port is configured to receive power from a first power source, and the discharging port is configured to supply power to a load. The electric vehicle also includes an on-board charging control module electrically coupled to the charging port. The on-board charging control module includes a first processing unit configured to process power from the first power source to charge the battery. The electric vehicle also includes a separator module electrically coupled to the discharging port. The separator module is located between the charging port and the on-board charging control module and is used to direct power from the first power source to the discharging port to supply power to the load when the vehicle is being charged simultaneously.
[0016] This aspect of the disclosure may include one or more of the following optional features. In some examples, the splitter module may be configured to change the voltage of the power supply. For example, the splitter module is configured to reduce the voltage of the first power supply. In such examples, the splitter module may include a sensing unit configured to measure the value of at least one of current and voltage and / or a switch operable for bypassing or engaging an AC-AC converter.
[0017] In some embodiments, the splitter module may include a second processing unit that receives a measurement of at least one of the current and the voltage to actuate the switch. The second processing unit may also be configured to actuate the AC-AC converter to generate a predetermined waveform.
[0018] In some implementations, a first processing unit of the on-board charging control module can transmit battery charging information to a second processing unit of the AC-AC converter, wherein the second processing unit processes the charging information to control the switch and maintain the desired waveform.

[0066] This disclosure relates to a power control system 10 for supplying power from a first power source 16 to a load 12 and a battery 14. The first power source 16 transmits power at a predetermined voltage in the form of alternating current to an on-board charging control module 18, which regulates the power to charge the battery 14. The first power source 16 may be a commercially developed charging station configured to provide 240 volts of power, or it may be a residential outlet configured to provide 120 volts of power.
[0067] The on-board charging control module 18 includes a first processing unit 20 configured to process power from a first power source 16 to charge the battery 14. A splitter module 22 is located between the first power source 16 and the on-board charging control module 18. The splitter module 22 is configured to direct power from the first power source 16 to a load 12. For example, the splitter module 22 may be configured to supply power to a discharge port 24 located in the vehicle 26, to which the load 12 may be coupled. The discharge port 24 may be a standard two-pin or three-pin discharge port for U.S. purposes, or a two-pin discharge port for European purposes. Therefore, power can be supplied to the load 12 while the battery 14 is charging.
[0068] The power control system 10 can be implemented in any platform or device that uses battery 14 to power equipment (such as a motor for propulsion). For illustrative purposes, in such... Figure 1 The power control system 10 is described in the context of the electric vehicle 26 shown. However, it should be understood that the power control system 10 can be implemented in other devices / platforms having a battery 14 for powering the device / platform and a discharge port 24 for powering the load 12, such devices / platforms illustratively include boats, motorcycles, residential or commercial buildings, etc.
[0069] Figure 1 A vehicle 26 coupled to a first power source 16 is depicted. Specifically, vehicle 26 includes a charging port 28, and the first power source 16 includes a charger 38 configured to couple with the charging port 28 to provide power to charge the battery 14. The first power source 16 is illustratively shown as a commercial charging station; however, it should be understood that the first power source 16 could also be a residential outlet.
[0070] Vehicle 26 is an electric vehicle 26 having a battery 14 configured to power a motor 30 for driving vehicle 26. For example, motor 30 may be configured to generate up to 200 horsepower to drive vehicle 26. Any battery 14 configured to be charged with electricity currently known or developed hereafter may be modified for use herein, illustratively including lithium-ion batteries, solid-state batteries, and the like. The capacity of battery 14 need not be limiting and may include batteries 14 having a capacity greater than 30 kilowatts (kW). Battery 14 is also configured to power various electronic components within vehicle 26. Such electronic components are well known and illustratively include lights, windshield wipers, vehicle audio systems, heating and air conditioning systems, etc.
[0071] Now for reference Figure 2 and 3 The power control system 10 includes an on-board charging control module 18 and a splitter module 22. In some configurations, the on-board charging control module 18 and the splitter module 22 are integrated into a single module. In other configurations, the on-board charging control module 18 and the splitter module 22 are separate units. The on-board charging control module 18 is configured to regulate the power from a first power source 16 to charge the battery 14. For example, the on-board charging control module 18 may include electronic circuitry and components configured to filter noise, maintain the power supplied to the battery 14 at a predetermined voltage, maintain a predetermined waveform, and perform other conventional processes to provide the battery 14 with the optimal power for charging operations. For example, the on-board charging control module 18 may include a power factor correction circuit configured to regulate the power flowing to the battery 14 and one or more power discharge ports 24 within the vehicle 26.
[0072] The on-board charging control module 18 includes a switch 32 (such as a MOSFET switch) that can be turned on and off to regulate the duty cycle of the power supply, increase or decrease the voltage, and change the waveform of the power supplied to the battery 14. The on-board charging control module 18 can also be configured to provide electrical isolation between the load 12 and the battery 14. For example, the on-board charging control module 18 may also include an isolated DC-DC converter, which may include a transformer. Operation of the transformer provides electrical isolation between the load 12 and the battery 14.
[0073] The on-board charging control module 18 may include a first processing unit 20 configured to actuate electronic components (such as switch 32) to process power from a first power source 16, thereby charging the battery 14. The first processing unit 20 includes programming instructions for executing the electronic components. These instructions may be stored in non-volatile memory that can be updated as needed.
[0074] Refer again Figure 2 And now refer to Figure 3 The power control system 10 includes a splitter module 22 located between a first power source 16 and an on-board charging control module 18. In one aspect, the first power source 16 includes a first output line 34 and a second output line 36, from which power is delivered. In this aspect, the second output line 36 is a neutral line used to generate a power difference with respect to the first output line 34 for power delivery. The first output line 34 and the second output line 36 may be housed within a charger 38 of the first power source 16 and configured to couple with a charging port 28 disposed on the vehicle 26. The on-board charging control module 18 includes a first input line 40 and a second input line 42, configured to be electrically coupled to the first output line 34 and the second output line 36, respectively, to receive power from the first power source 16. The first input line 40 and the second input line 42 are electrically coupled to electronic components of the on-board charging control module 18, which regulates the delivered power.
[0075] The splitter module 22 includes a third input line 44 and a fourth input line 46, which are configured to direct power from the first power source 16 to the load 12. The third input line 44 and the fourth input line 46 are electrically coupled to the first output line 34 and the second output line 36, respectively. It should be understood that the first input line 40, the second input line 42, the third input line 44, and the fourth input line 46 can be housed in the charging port 28. It should be understood that the splitter module 22 does not necessarily provide direct electrical coupling to the load 12, but can be configured to supply power to a discharge port 24 to which the load 12 can be coupled. Therefore, when the battery 14 is charged, power can be supplied to the load 12. It should be understood that the first output line 34, the second output line 36, the first input line 40, the second input line 42, the third input line 44, and the fourth input line 46 can be formed of conductive wires or cables, which are formed of multiple conductive wires.
[0076] Refer again Figure 2 And now refer to Figure 3 The splitter module 22 includes an AC-AC converter 48 configured to regulate power from the first power source 16. Any AC-AC converter 48 currently known or developed hereafter can be modified for use herein, illustratively including buck converters, buck-boost converters, single-ended primary inductor converters 58, switched capacitor AC-AC converters, and back-to-back AC-AC converters.
[0077] In one aspect, the AC-AC converter 48 includes a first capacitor 50 and a second capacitor 52 interconnecting a third input line 44 and a fourth input line 46. A first switch 54 is located between the first capacitor 50 and the second capacitor 52 to be connected in parallel with the third input line 44 and the fourth input line 46, and to connect or disconnect the power between the third input line 44 and the fourth input line 46. A second switch 56 is disposed on the fourth input line 46 electrically connected to a second output line 36. The second switch 56 is also located between the first switch 54 and the second capacitor 52. The AC-AC converter 48 may also include an inductor 58 disposed on the fourth input line 46 and connected in series with the second switch 56. The inductor 58 is located between the first switch 54 and the first capacitor 50. By operating the first switch 54 and the second switch 56, the splitter module 22 can be configured to change the voltage and waveform of the power supply. For example, the splitter module 22 can be configured to increase or decrease the voltage supplied to the load 12.
[0078] Now for reference Figure 4 The splitter module 22 is configured to bypass the AC-AC converter 48. For example, the splitter module 22 may include a sensing unit 60 configured to measure the value of at least one of current and voltage. The sensing unit 60 may be any current or voltage sensor currently known or applicable hereafter, and may be modified for use herein, including resistors, diodes, combinations of resistors and diodes, etc. The sensing unit 60 is operatively coupled to corresponding first and second switches 54 and 56 to detect or otherwise sense current and / or voltage at the first and second switches 54 and 56. The sensing unit 60 is communicatively coupled to a second processing unit 62 configured to measure the values of voltage and / or current to control the operation of the first and second switches 54 and 56.
[0079] The splitter module 22 may include a third switch 64 operable to bypass or engage the AC-AC converter 48. In this respect, the splitter module 22 includes a fifth input line 66 coupled in parallel with the fourth input line 46, wherein the inductor 58, the first switch 54, and the second switch 56 are bypassed.
[0080] The second processing unit 62 receives a measurement of at least one of current and voltage to actuate the third switch 64. Therefore, when the first power supply 16 provides 240 volts, the sensing unit 60 detects the voltage and / or current, and the second processing unit 62 keeps the third switch 64 open to direct power to the AC-AC converter 48. In this case, the second processing unit 62 also actuates the first switch 54 and the second switch 56 to reduce the power to 120 volts, thereby generating a predetermined duty cycle to output a waveform suitable for commercial electronic devices such as laptops and / or mobile devices. When the first power supply 16 provides 120 volts, the sensing unit 60 detects that 120 volts have been provided, and the second processing unit 62 keeps the third switch 64 closed to bypass the AC-AC converter 48. The 120 volts of power from the first power supply 16 are then directly output to the charging port.
[0081] Now for reference Figure 5 and 6 It provides a depiction of the waveform output by the separator module 22. Figure 4 An exemplary waveform output from the first power source 16 is shown. This waveform is typically sinusoidal, which may not be optimal for some electronic devices. The second processing unit 62 can also be configured to actuate the AC-AC converter 48 to generate a predetermined waveform. For example, the first processing unit 20 of the on-board charging control module 18 can be configured to transmit charging information from the battery 14 to the second processing unit 62 of the AC-AC converter 48, wherein the second processing unit 62 processes the charging information to control the switch and maintain the desired waveform, such as... Figure 5 As shown in the diagram. This can be accomplished by selectively actuating the first switch 54 and the second switch 56.
[0082] Refer again Figure 3 and Figure 4 This provides operation of the power control system 10. In operation, the charger 38 of the first power source 16 is coupled to the charging port 28. The splitter module 22 draws power from the first power source 16 to the discharge port 24 located in the vehicle 26, as indicated by the dotted line, and the power from the first power source 16 is directed to the on-board charging control module 18, as indicated by the dashed line. When the first power source 16 provides 240 volts, the AC-AC converter 48 reduces the power and can adjust the waveform of the power to provide 120 volts to the discharge port 24, as shown below. Figure 3 As shown in the diagram. Therefore, while vehicle 26 is being charged, the user may be able to power electronic devices. In particular, when battery 14 is being charged, the user can draw power directly from the first power source 16. With the first power source 16 providing 120 volts, the AC-AC converter 48 can be bypassed, as shown in the diagram. Figure 4As shown in the diagram. Therefore, when vehicle 26 is being charged, the user may be able to power electronic devices. In particular, when battery 14 is being charged, the user can draw power directly from the first power source 16. In both cases, the splitter module 22 can also be configured to modify the power waveform to a predetermined waveform.
