Power delivery assembly

Abstract

A number of exemplary embodiments of power delivery (PD) assemblies are disclosed, including power, charging and data connection devices that can be used within a vehicle or the like. In a number of exemplary embodiments, a power brick (such as a standalone power brick, wireless charger, or the like) can be connected to a user interface (PD charger only) or a user interface (USB hub with charging and data transfer) via a vehicle harness. Thus, a power brick having the same / common form factor and having the same / common configuration (Vbus PD, GND, CC1, CC2) vehicle harness can thus be used interchangeably to connect to a charging only user interface or a user interface with charging and data transfer.

[0002] This application claims priority to U.S. Provisional Application US62 / 948345, filed December 16, 2019, which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to the field of power delivery (PD), and more specifically (but not exclusively) to devices for power supply, charging, and data connectivity. Background Technology

[0004] This section provides background information related to the contents of this disclosure, which is not necessarily prior art.

[0005] The vehicle may be equipped with a USB panel-mount hub (Figure 1), a USB embedded hub (Figure 2), a USB panel-mount charger (Figure 3), or a USB embedded charger (Figure 4). For example, Figure 1 shows a conventional USB panel-mount hub 101, and the vehicle wiring harness includes a USB cable 109 (Vbus, Data+, Data-, ground (GND)) extending between a dual-port USB user interface 113 and a flat panel display 117.

[0006] Figure 2 shows a conventional USB embedded hub 201, and the automotive wiring harness includes a USB cable 209 (Vbus, Data+, Data-, Ground (GND)) extending between a dual-port USB user interface 213 and a flat panel display 217. An additional power / USB cable 221 (Vbus PD, Data+, Data-, GND, CC1, CC2) connects to the dual-port USB user interface 213.

[0007] Figure 3 shows a conventional USB panel-mounted charger 301, and the automotive wiring harness includes a battery cable 325 connected to a dual-port USB user interface 313. Figure 4 shows a conventional USB embedded charger 401, and the automotive wiring harness includes a battery cable 425 connected to a dual-port USB user interface and additional power / USB cables 421 (Vbus PD, Data+, Data-, GND, CC1, CC2). Figure 5 This is a block diagram showing various components 503 that can be used with the embedded hub 201 shown in Figure 2.

[0008] As recognized herein, a conventional USB panel-mount hub 101 (Figure 1) offers a cost-effective solution because it does not include the high-cost power / USB cable 221 (Vbus PD, Data+, Data-, GND, CC1, CC2) shown in Figure 2. However, this conventional USB panel-mount hub 101 is limited in its module size and power dissipation by the maximum permissible surface temperature of the panel that the end user will come into contact with, making overheating and heat dissipation issues important considerations. Furthermore, the conventional USB panel-mount hub 101 is constrained by the panel opening and surrounding electronic components, making electrostatic discharge (ESD) issues an important design consideration.

[0009] Compared to a conventional USB panel-mount hub 101, a conventional USB embedded hub 201 (Figure 2) is more expensive due to the additional power / USB cables 221 (Vbus PD, Data+, Data-, GND, CC1, CC2). Furthermore, the conventional USB embedded hub 221 is constrained by cable length and signal integrity, which are important design considerations.

[0010] The conventional USB panel-mount charger 301 (Figure 3) offers a cost-effective solution because it does not include the high-cost power / USB cable 421 (Vbus PD, Data+, Data-, GND, CC1, CC2) shown in Figure 4. However, the conventional USB panel-mount charger 301 is limited in its module size and power dissipation by the maximum permissible surface temperature of the panel that the end user will come into contact with, making overheating and heat dissipation issues important considerations. Furthermore, the conventional USB panel-mount charger 301 is constrained by the panel opening and surrounding electronic components, making electrostatic discharge (ESD) issues an important design consideration.

[0011] Compared to a conventional USB panel-mounted charger 301, a conventional USB embedded charger 401 (Figure 4) is more expensive due to the additional power / USB cable 421 (Vbus PD, Data+, Data-, GND, CC1, CC2) mentioned above.

[0012] Given the aforementioned limitations and drawbacks associated with conventional USB panel-mount hub 101 (Figure 1), USB embedded hub 201 (Figure 2), USB panel-mount charger 301 (Figure 3), and USB embedded charger 401 (Figure 4), some people will appreciate improvements in such power delivery components. Summary of the Invention

[0013] This section provides a general summary of the disclosure and is not a complete disclosure of its entire scope or all its features.

[0014] Several exemplary embodiments of power delivery (PD) components are disclosed, including devices for power supply, charging, and data connectivity that can be used in vehicles, etc. In several exemplary embodiments, a power block (e.g., a standalone power block, a wireless charger, etc.) can be connected via an automotive wiring harness to a user interface (PD charger only) or a user interface (USB hub with charging and data transfer).

[0033] In several figures that are included in the appendix, the corresponding reference numerals may indicate the corresponding parts (but are not necessarily the same). Detailed Implementation

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings.

[0035] Having recognized the limitations and drawbacks associated with the conventional USB panel-mount hub 101 (FIG. 1), USB embedded hub 201 (FIG. 2), USB panel-mount charger 301 (FIG. 3), and USB embedded charger 401 (FIG. 4) described above, this document develops and discloses exemplary embodiments of power delivery components for devices including power supply, charging, and data connectivity. For example, Figure 6 An embedded power delivery architecture according to an exemplary embodiment is shown.

[0036] Figure 6 Generally, this refers to a module aspect or modularity that can be implemented using exemplary embodiments of this disclosure. As disclosed herein, a power block 604 (e.g., a standalone power block, a wireless charger, etc.) can be connected to a user interface (charger only) 608 or a user interface (USB hub with charging and data transfer) 612 via a common automotive wiring harness. Thus, multiple power blocks having the same / common form factor and multiple automotive wiring harnesses having the same / common configuration (VbusPD, GND, CC1, CC2) can therefore be used interchangeably to connect to a charger-only user interface or to a user interface with charging and data transfer.

[0037] User interface 608 may include a USB port 616 of type A and / or type C. User interface 608 may also include a USB connection 620 for a CDP (Charging Downlink) option. A regular cable 624 connects power block 604 and user interface (charger only) 608. Thus, a high-speed data cable is not required to connect power block 604 and user interface (charger only) 608.

[0038] Additionally, a wireless charger 628 or a standalone power block 632 (e.g., an embedded PD dual-port power block) can be connected to the user interface 612 (a USB hub with charging and data transfer capabilities) via a power and control line 636. A high-speed data cable is not required to connect the wireless charger 628 or the standalone power block 632 to the user interface 612 (a USB hub with charging and data transfer capabilities).

[0039] Multiple power block modules with the same / common form factor and multiple automotive wiring harnesses with the same / common configuration (Vbus PD, GND, CC1, CC2) can be connected to various user interfaces with different configurations, such as single-port (A or C), two-port (A+C or C+C), four-port, standard 15W, 30W, 45W, 60W, or 100W power delivery chargers, circular form factors, MicoMCM form factors, panel-mounted single cables, DC / AC inverters, USB connections for CDP (Charging Downlink Port) options, etc. This, in turn, provides modularity, as the same power block modules and the same automotive wiring harnesses can be connected to either user interface type (e.g., user interface (charger only)) or user interface (USB hub with charging and data transfer) without requiring changes to the vehicle configuration to accommodate different power block modules and different automotive wiring harnesses for different user interface types. Reusing the same vehicle wiring harnesses and power block modules for two user interface types also eliminates the need for and additional costs of EMC (electromagnetic compatibility) testing for different designs. In other words, reusable automotive wiring harnesses and modular power block modules will not need to undergo repeated EMC testing. Conventional embedded solutions (e.g., USB embedded hub 201 (Figure 2), USB embedded charger 401 (Figure 4)) have traditionally been avoided due to their relatively high cost (e.g., expensive additional power / data cables 221 (Figure 2), 421 (Figure 4)). The modularity and reduced cost achievable using the exemplary embodiments disclosed herein allow for embedded solutions at a lower cost than conventional embedded solutions 201 (Figure 2), 401 (Figure 4).

[0040] Figure 7 An embedded hub 700 according to an exemplary embodiment is shown. As shown, an automotive wiring harness 736 (Vbus PD, GND, CC1, CC2) connects a power block 732 and a dual-port user interface (USB hub with charging and data transfer capabilities) 712. A USB cable 738 (Vbus, Data+, Data-, Ground (GND)) extends between the user interface 712 and the flat panel display 740.

[0041] Figure 8 A USB embedded charger 800 according to an exemplary embodiment is shown. As shown, an automotive wiring harness 836 (Vbus PD, GND, CC1, CC2) connects a power block 832 to a dual-port user interface 808 (charger only).

[0042] Figure 7 and Figure 8Together, it indicates that the same / common power blocks 732 and 832 can be connected to the user interface (USB hub with charging and data transfer) 712 via the same / common automotive wiring harnesses 736 and 836. Figure 7 ) or connected to the user interface (charger only) 808 ( Figure 8 The power block may include a wireless charger and / or a separate power block. The automotive wiring harness includes Vbus, GND, CC1, and CC2 lines between the power block and the user interface.

[0043] Compared to the conventional USB embedded hub 201 (Figure 2), the embedded hub 700 ( Figure 7 It can provide one or more of the following advantages or features (but not necessarily any or all of them): avoidance of the use of expensive power / USB cables 221 (in Figure 2, etc.), avoidance of constraints imposed by cable length and signal integrity, size and power dissipation are not significantly limited by the mounting location, panel size or surrounding components, lower cost than conventional USB embedded hubs 201, and reduced overall system cost when the power block is embedded together with embedded wireless chargers, etc.

[0044] Compared to the conventional USB embedded charger 401 (Figure 4), the USB embedded charger 800 ( Figure 8 It can provide one or more of the following advantages or features (but not necessarily any or all of them): when termination (e.g., Figure 11 (etc.) avoids the use of expensive cables at the USB module location, and the size and power dissipation are not significantly limited by the installation location, panel size or surrounding components. The cost is lower than that of conventional USB embedded chargers 401. It provides greater flexibility for USB hub or charger applications by using the same / common power module (e.g., the same / common automotive wiring harness and power block with the same / common form factor). The overall system cost is reduced when the power block is embedded together with wireless chargers, etc.

[0045] Figure 9 A power block 932, a user interface (charger only) 908, and a user interface (USB hub with charging and data transfer) 912 are shown according to an exemplary embodiment. Figure 9 As shown, the power block 932 can be connected to the user interface (charger only) 908 or the user interface (USB hub with charging and data transfer) 912 via the vehicle wiring harness 936.

[0046] The power block 932 may be a standalone module or embedded in a vehicle as part of a wireless charger or other electronic control unit (ECU). The automotive wiring harness 936 may include, for example... Figure 7 and Figure 8 The Vbus line, GND line, CC1 line, and CC2 line shown are provided, but there is no high-speed data line between the power block and the user interface.

Figure 10 As shown, the user interface 912 includes or includes connectors for receiving signals from the power block (Vbus, GND, CC1, CC2 for each port). The user interface 912 with a USB hub also includes or includes connectors for receiving signals from the USB host (Vbus, DP / DM, GND). Furthermore, the user interface 912 with a USB hub includes a USB hub chip, a USB Type-C connector, and support circuitry for providing USB functionality and allowing mirroring applications such as Android Auto and Apple CarPlay. Additional USB features can be supported depending on the functionality provided by the USB chipset.

Figure 11 As shown, user interface 908 includes or contains connectors for receiving signals from the power block (Vbus, GND, CC1, CC2 for each port). User interface 908 also includes or contains BC1.2 terminations and a USB Type-C connector for the user interface. This configuration eliminates the need for expensive cables for high-speed data, allows for a small mechanical form factor, and avoids costly EMC testing.

Figure 10 ) or connected to the user interface (PD charger only) 908 ( Figure 11 (Connection.) For example... Figure 12As shown, power block 932 includes or contains connectors for receiving control signals from the vehicle (as required by each application) and the power line (Batt+ / -). Power block 932 is configured to convert the input voltage to the voltage required for USB power delivery. Power block 932 includes circuitry for protecting electronic components. Power block 932 also includes a filter for EMC noise generated by the conversion circuitry. Power block 932 also includes a USB power delivery controller and output connectors (Vbus, GND, CC1, CC2 for each port).

[0050] Figures 13 to 17 This illustration shows a vehicle configuration including embedded power delivery and an embedded charger according to an exemplary embodiment. Generally speaking, Figures 13 to 17 This illustrates a modularity achievable through exemplary embodiments, where power block modules with the same / common form factor and automotive wiring harnesses with the same / common configuration (Vbus PD, GND, CC1, CC2) can be connected to a user interface type (e.g., a user interface (PD charger only)) or a user interface (a USB hub with charging and data transfer) without requiring changes to the vehicle configuration to accommodate different power block modules and different automotive wiring harnesses for different user interface types. As will be appreciated, various parts of the vehicle can be modified to meet desired configurations by adjusting the number of charging ports provided and the supported power levels.

[0056] Figure 18An embodiment of a combined wireless charger and a power block integrated into a single housing is shown. A pad 1810 is configured to receive a portable device that will wirelessly receive power. The pad can be shaped as needed to hold the portable device, and therefore, while a simple design is shown, more complex three-dimensional shapes would also be suitable. A first housing portion 1820 and a second housing portion 1870 are configured to help support internal components. A first substrate 1830 can be formed from conventional circuit board material or any other suitable substrate material, capable of providing a desired level of shielding. A transmission coil module 1840 is configured to transmit power to the portable device and may be a coil of one or more individuals providing wireless power transmission. A second substrate 1850 can be constructed in a similar manner to substrate 1830 and may include circuitry supporting wireless power delivery as well as the circuitry discussed above for providing the power block. Due to this increased complexity, the second substrate may have additional layers to provide the necessary communication and power delivery between the different components mounted thereon. Of course, for higher power levels, heat dissipation becomes an issue, and it is preferable to place the power block circuitry on a separate substrate to help space out multiple heat sources; however, modifications to this configuration are known in the art and will not be discussed here. A heat sink 1860 is configured to help dissipate the heat generated by the power block circuitry and the wireless power delivery circuitry. The size and configuration of the heat sink will naturally be adjusted in a known manner to meet cooling requirements. One advantage of such a design is that, assuming heat dissipation is properly managed, it is possible to reduce the overall system cost by sharing components rather than requiring complete duplication of components.

[0057] In several exemplary embodiments, a power delivery assembly includes a power block, a user interface module, and a cable harness. The power block includes one or more connectors comprising a Vbus line, a GND line, a CC1 line, and a CC2 line for each port to support power delivery (PD). The user interface module is configured to operate as a USB hub with power delivery (PD) or as a charger-only device with power delivery (PD). The cable harness is configured to interconnect the power block and the user interface module, regardless of whether the user interface module is configured to operate as a USB hub with power delivery (PD) or as a charger-only device with power delivery (PD). The power delivery assembly may further include a high-speed data cable configured to connect the user interface module to a host for a USB hub application.

[0058] The user interface module may include a first user interface module configured to operate as a USB hub with power delivery (PD) and a second user interface module configured to operate as a charger-only device with power delivery (PD). In this configuration, the power block may be selectively interconnected via the wiring harness with one of the first or second user interface modules.

[0059] The user interface module may include one or more first user interface modules configured to operate as a USB hub with power delivery (PD), and one or more second user interface modules configured to operate as a charger-only device with power delivery (PD). The power blocks may include multiple power blocks having the same / common form factor. The wiring harnesses may include multiple automotive wiring harnesses, each having the same / common configuration, for interconnecting the multiple power blocks with the first and second user interface modules. Each power block can be selectively interconnected with any of the first and second user interface modules via any of the multiple automotive wiring harnesses without requiring changes to the vehicle configuration to accommodate different power block modules and / or different automotive wiring harnesses for different user interface types.

[0060] The user interface module may include at least one first user interface module configured to operate as a USB hub with power delivery (PD), the USB hub with power delivery (PD) including: an input connector for receiving Vbus, GND, CC1, and CC2 lines from each port of the power block; an input connector for a high-speed USB data line; electronic circuitry including the USB hub and circuitry for providing USB functionality; and a USB Type-C connector for each port for interfacing with an end-user device. The at least one first user interface module may further include: a printed circuit board assembly including one or more electronic circuits; and a mechanical enclosure configured to protect the one or more electronic circuits of the printed circuit board assembly.

[0061] The user interface module may include a second user interface module configured to operate as a power delivery (PD) charger-only module, the power delivery (PD) charger-only module including: an input connector for receiving Vbus, GND, CC1, and CC2 lines from each port of the power block; electronic circuitry for terminating DP / DM lines from an end-user equipment at each port; and a USB Type-C connector for each port for interfacing with an end-user equipment.

[0080] The numerous exemplary embodiments of the power delivery components disclosed herein may provide or include one or more (but not necessarily all) of the following advantages or features. For example, the numerous exemplary embodiments may include multiple power modules and multiple user interfaces configured to be physically separate, such that the same / common power module can be used in many types of charging and / or data transfer (e.g., USB) systems, thereby creating a higher-capacity / lower-cost device that can be part of a wide variety of custom systems. For example, the power module may include wireless charging functionality, USB hub functionality, and USB charging support. For example, a powerbox may include an input power connector, an input filter, a DC-DC converter (buck to support 5V output or buck-boost to support PD), a PD controller for each port, and a standard output connector for each port. For the user interface, an exemplary module may include the mechanical form factor required for the user interface and panel mounting (e.g., decorative or non-decorative). The exemplary user interface module may include an input connector (power and signal lines from the power block), a USB 2.0 controller (for charger applications with D+ / - termination and supporting resistors for legacy BC1.2), and a USB hub for applications with charger and data transfer.

[0081] The required user interface can be connected to the power module but is typically located at or remotely from it. Thermal issues can be addressed within the design and location of the power module (e.g., via thermal interface materials, thermal diffusers, heat sinks, etc.), rather than being integrated with or within the user interface, or addressed at separate locations within the user interface. This, in turn, allows for a lightweight and low-profile user interface, thereby providing improved flexibility in its placement and location. In several exemplary embodiments, the integration of wireless charging and power delivery charging can provide system benefits for the entire vehicle consumer's device charging scheme (e.g., in the front and second rows).

[0082] Several exemplary embodiments include a common power block with the same connectivity interface and form factor for all options, allowing upgrades from standard USB chargers to power delivery (PD), different power levels, and different variants. In several exemplary embodiments, a power block may be incorporated into a wireless charger, which may allow the use of common blocks (e.g., input connectors, filters, and integrated PD controllers).

[0083] In several exemplary embodiments, the user interface may have a relatively small size and / or be configurable to fit complex areas or areas where power dissipation is a concern (e.g., seats, armrests, cup holders, doors, etc.). Several exemplary embodiments may be configured to allow for easy customization of the user interface form factor. In several exemplary embodiments, the same / common interface may be used for the charger and subsequently upgraded to power delivery, allowing a charger to be interchanged with a USB hub layout by changing the user interface block. In several exemplary embodiments, the connection from the power block to the user interface may be part of the vehicle wiring harness.

[0084] In several exemplary embodiments, a power delivery component can be configured to provide up to 60W or 100W of USB power delivery, thereby enabling the power delivery component to be operable for powering a wide range of electronic devices, making compliance and certification of USB power delivery easier and / or more cost-effective.

[0085] The foregoing description of embodiments has been provided for purposes of explanation and illustration. It is not intended to be exclusive or limiting of this disclosure. Elements, intended or illustrated uses, or features of an individual embodiment of a particular embodiment are generally not limited to that particular embodiment; however, where applicable, elements, intended or illustrated uses, or features of that particular embodiment are interchangeable and can be used in an alternative embodiment, even if that alternative embodiment is not specifically shown or described. Similarly, modifications are possible in many ways. These modifications should not be considered a departure from this disclosure, and all such modifications are intended to be included within the scope of this disclosure.
