Description

Background Technology

[0001] This disclosure relates to wireless charging devices, and more specifically, to systems and methods for optimizing wireless charging rates.

[0002] All-electric or hybrid electric vehicles are able to achieve greater range thanks to advancements in battery technology and capacity. Some batteries, such as traction batteries, provide power in the form of direct current (“DC”). The DC power from the traction battery can be converted to alternating current (“AC”) by a power module to drive the traction motor or operate another part of the vehicle. In some cases, the traction battery is recharged through regenerative braking or from an external power source selectively connected to the traction battery. The vehicle may also be able to use power from the traction battery to charge other devices in the vehicle's passenger compartment, such as mobile devices. Summary of the Invention

[0068] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and, together with this description, explain the principles of the present disclosure.

[0069] Figure 1 The illustration schematically depicts a vehicle with a rechargeable energy storage system (RESS) wireless charging assembly and the wireless charging assembly associated with the vehicle.

[0070] Figure 2 The illustration shows the relationship with Figure 1 Wireless charging components associated with the vehicle.

[0071] Figure 3 It is an operation Figure 1 The flowchart shows an example method of one of the wireless charging components. Detailed Implementation

[0072] Those skilled in the art will recognize that terms such as “above,” “below,” “upward,” “downward,” “top,” “bottom,” “left,” and “right” are used descriptively with respect to the accompanying drawings and do not imply a limitation on the scope of this disclosure as defined by the appended claims. Furthermore, the various teachings herein can be described according to functional and / or logical block components and / or various processing steps.

[0073] Based on the non-restrictive example, in Figure 1 In this context, vehicles are generally designated as 10. In the illustrated example, vehicle 10 includes a body 12 supported on wheels 16, one or more of which are steerable. The body 12 partially defines a passenger compartment 20 having a seat 23 located behind an instrument panel 26. A steering controller 30 is arranged between the seat 23 and the instrument panel 26. The steering controller 30 is operated to control the orientation of one or more of the steerable wheels 16.

[0074] Vehicle 10 includes a motor 34 connected to a transmission 36, which powers one or more wheels 16. A rechargeable energy storage system (RESS) 38 is disposed within the body 12 and supplies power to the motor 34. However, the positions of the motor 34, transmission 36, and RESS 38 relative to the body 12 may differ. Figure 1 The locations shown in the diagram.

[0075] like Figure 1 As shown, the RESS wireless charging component 40 is configured to provide power to the vehicle 10 to charge the RESS 38 without forming a direct electrical connection with a charging port on the vehicle 10. A feature of this disclosure is the wireless provision of power to another device at a power transfer rate optimized based on several different parameters, which will be discussed in more detail below. Although Figure 1 The illustration shows wireless charging of vehicle 10 using component 40, but this disclosure applies to applications as referenced. Figure 2 and Figure 3 Other types of devices that can be wirelessly charged (72) Figure 2 ).

[0076] exist Figure 1In the illustrated example, component 40 includes an electronic control unit (ECU) 46 in electrical communication with the wireless charging pad 42, an alternating current (AC) power supply 44, at least one sensor 54, and at least one scale 56. While the illustrated example shows a separate scale 56 for each wheel 16, a single scale 56 can be used to weigh the entire vehicle 10 at a given time. The scale 56 and charging pad 42 are supported by the road surface 15 and are in electrical communication with the ECU 46. The AC power supply 44 can be located remotely from component 40 or positioned adjacent to component 40, such as in an electric vehicle (EV) charging station.

[0077] In order to wirelessly charge the RESS 38 on the vehicle 10 using component 40, ECU 46 selectively applies AC power from AC power source 44 to charging pad 42. When AC power is applied to charging pad 42, a magnetic field 48 is generated by coil 43 within charging pad 42, wherein magnetic field 48 is directed toward sensing element 50 of vehicle 10.

[0078] When the sensing element 50 on vehicle 10 is within the range of magnetic field 48, AC power is induced in the sensing element 50. In one example, the sensing element 50 includes a coil 51 located therein for inducing AC power. The AC power generated within the sensing element 50 can be converted into direct current (DC) by a converter 52 controlled by ECU 54 on vehicle 10 to charge RESS 38 with DC power. Alternatively, the AC power generated by the sensing element 50 can be directed by ECU 54 to a portion of vehicle 10 that operates on AC power.

[0079] Sensor 49 may include at least one of an optical sensor or a radar-based sensor positioned adjacent to component 40, such that sensor 49 includes a field of view of charging pad 42. In one example, sensor 49 is used to determine the presence of a vehicle to be charged by component 40. In another example, sensor 49 acquires an image of the area surrounding charging pad 42 for object detection using ECU 46 or by transmitting the image to a computer at a remote location 55 via data connection 47 (such as Bluetooth, Wi-Fi, or a network connection). Object detection can identify vehicle 10 or objects, such as debris, adjacent to charging pad 42 that may interfere with charging vehicle 10. Object detection can also be used to identify the vehicle model to obtain information about vehicle 10, thereby optimizing the charging rate generated by component 40. Information about vehicle 10 may be stored in memory on ECU 46 or at a remote location 55, and this information is transmitted to ECU 46 for optimizing the charging rate.

[0080] like Figure 1-2 As shown, vehicle 10 may also include an additional wireless charging component 70. (As illustrated) Figure 1As shown, component 70 is integrated into or on vehicle 10, and Figure 2 In this context, component 70 is shown as separate from or independent of vehicle 10, such that component 70 can be used in residential or commercial spaces or other locations where AC power can be used.

[0081] like Figure 2 As illustrated in the example diagram, component 70 includes a charging pad 74, a scale 78, at least one sensor 84, and an ECU 80. The charging pad 74 includes a device support surface 75 for supporting a device 72 thereon. The ECU 80 is configured to selectively apply AC power from an AC power source 82 to a coil 76 located within the charging pad 74. Figure 1 As shown, AC power 82 can be supplied by vehicle 10, and as Figure 2 As shown, the AC power can come from another source, such as an outlet in a residential or commercial building. ECU 80 can also communicate with scale 78 to weigh device 72 when it is placed on charging pad 74.

[0082] In this disclosure, an ECU (such as ECU46, 54, or 80) may be equipped with one or more processors (P) (e.g., logic circuitry, combinational logic circuitry, application-specific integrated circuits (ASICs), electronic circuitry, central processing units, semiconductor IC devices, etc.), and one or more input / output (I / O) circuitry, appropriate signal conditioning and buffering circuitry, and other components such as a high-speed clock, to provide the SOC functions described in the preceding figures, as well as the various functions identified by the CC input signals. The ECU also includes associated non-transitory computer-readable storage media (i.e., memory (M) containing read-only, programmable read-only, random access, hard disk, etc.), whether internal, remote, or a combination of both. Control routines, including code for executing a SOC model with hysteresis, are executed by the processor to monitor relevant inputs from sensing devices and other networked control modules (not shown) and to execute control and diagnostic routines to manage the operation of vehicle 10 or components 40 and 70.

[0083] While component 40 is configured to charge larger devices (such as vehicle 10), component 70 is configured to wirelessly charge smaller or handheld devices 72. For example, the device 72 charged by component 70 may include a mobile phone, tablet, laptop computer, removable battery pack, or power tool. Figure 2As illustrated in the example diagram, device 72 includes a sensing element 72I or is in electrical communication with the sensing element 72I. AC power is induced in the sensing element 72I when it interacts with the magnetic field 77 generated by the charging pad 74. Device 72 can use a converter 72C to convert the AC power into DC power for charging the battery 72B integrated into device 72.

[0084] Sensor 84 may include at least one of an optical sensor or a radar-based sensor, positioned adjacent to component 70 such that it includes a field of view of the support surface 75 on the charging pad 74. In one example, sensor 84 is used to determine whether device 72 is located on the charging pad 74. In another example, sensor 84 acquires an image of the area surrounding the charging pad 74 for object detection using ECU 80 or by transmitting the image to a computer at a remote location 55 via data connection 86 (such as Bluetooth, Wi-Fi, or a network connection). Object detection can identify objects, such as debris, adjacent to the charging pad 74 that may interfere with charging of device 72. Object detection can also be used to identify device 72 to obtain information about device 72, thereby optimizing the charging rate generated by component 70.

[0085] Components 40 or 70 can identify when a device is ready to charge by using a weighing device (such as vehicle 10 or device 72) such as scale 56 or 78, respectively. In one example, scale 78 in component 70 can help identify a specific device 72 with a predetermined and consistent weight, such as a mobile phone or tablet. In another example, scale 56 in component 40 can help identify the category of the device, such as a bus, truck, or heavy vehicle. Sensors 49 and 84 can help determine whether vehicle 10 or device 72 is positioned adjacent to charging pad 42 or 74, respectively. Furthermore, sensors 49 and 84, with or without scales 56 and 78, can identify foreign objects, such as debris, that may interfere with the charging process.

[0086] Figure 3An example method 100 for operating component 40 or 70 to perform wireless charging is illustrated. Method 100 begins at box 102 (“Start”) and then proceeds to box 104. At box 104 (“Device detected?”), method 100 detects whether a device (such as vehicle 10 or device 72) is positioned in proximity to component 40 or 70. If no device is detected, method 100 returns to box 104 and continues to monitor for the device. Method 100 detects the device with component 40 or 70 by a number of different methods, such as by measuring changes in electromagnetic induction in charging pad 42 or 74, by wireless communication between the device and component 40 or 70, and by weighing the device with scales 56 and 78, respectively. Components 40 and 70 may also detect the device using data (such as image data or radar baseline data) from at least one sensor 54 or 84, respectively. Once a device is detected in proximity to component 40 or 70 as described above, method 100 proceeds to box 106.

[0087] At box 106 (“Known Device?”), method 100 determines whether the device detected in box 104 is a known device. Method 100 can determine whether the device detected from box 104 is a known device using many different methods. In one example, the detected device is wirelessly communicating with component 40 or 70. Method 100 can determine whether component 40 or 70 has previously communicated with the device based on information transmitted from the device, such information identifying the device by model or manufacturer, or whether the device has previously been charged by one of component 40 or 70.

[0088] In another example, method 100 can determine whether a device detected from box 104 is a known device by utilizing images captured by at least one sensor 54 or 84 from component 40 or 70, respectively. The captured images are evaluated using an object detection algorithm to determine whether the detected device is known. Method 100 can also allow the user to confirm that the detected device is known, or allow the user to confirm from display 27 on dashboard 26 of vehicle 10. Figure 1 Select from the list of possible known devices on the device.

[0089] In yet another example, method 100 can determine whether a detected device has been recognized by weighing the detected device using scales 56 or 78 from components 40 or 70, respectively. Using the measured weight of the detected device, method 100 can determine whether that weight matches the weight of one of the known devices. A feature of using device weight as part of the identification process is that the predetermined weight of the device can be updated if the user customizes and changes the weight (such as attaching a casing to a mobile device or using a different sized battery).

[0090] If the device is not known to component 40 or 70, method 100 proceeds to box 108 and generates a profile for the device. This profile may include information about the device collected as described above, including weight, images, or other data transmitted wirelessly between the device and component 40 or 70. Using the profile generated at box 108, method 100 returns to box 106 and confirms that the device is known before proceeding to box 110.

[0091] At box 110 (“Foreign Object Detected”), method 100 determines whether a foreign object is detected near 40 or 70. In one example, component 40 or 70 can detect a foreign object by comparing its measured weight to a predetermined weight of a given object, such as an object that cannot be wirelessly charged on charging pad 42 or 74, respectively. This comparison can be performed when a device is identified via wireless communication, object detection, or by measuring its weight within a predetermined weight range. For example, if the device is identified via image detection or wireless communication, and the difference between the predetermined weights exceeds a weight threshold. If the weight threshold exceeds a predetermined amount, method 100 proceeds to box 112 (“Prompt User”) and notifies the user of the possible foreign object. The user can then confirm whether a foreign object is present on component 40 or 70, or may remove the foreign object. If no foreign object is detected at box 110, method 100 proceeds to box 114.

[0092] At box 114 (“Collecting Information”), information about operating parameters of the device and component 40 or 70 is collected from boxes 116, 118, or 120. At box 116 (“Device Information”), information about the device is provided to box 114. Device information may include battery capacity, predetermined weight, maximum charging rate, acceptable operating temperature range, acceptable heat dissipation range, or the presence of accessories on the device (such as the housing of a mobile device).

[0093] At box 118 (“Charger Information”), information about component 40 or 70 is provided to box 114. In one example, this information includes ambient temperature, available charging rate, or the type of wireless charging component, such as a wireless charging component for handheld devices or large devices (such as vehicles).

[0094] At box 120 (“Historical Data”), historical charging data of the device is provided to box 114. Historical charging data may include the charging rate previously applied to the device and the associated heat dissipation level, or the charging duration associated with a change in battery level. In another example, historical data may include historical vehicle trip information, including trip duration.

[0095] Information from boxes 116, 118, or 120 can be stored in the memory of ECU 46 or ECU 80, or transmitted from remote location 55 to component 40 or 70. Using the information collected at box 114, method 100 proceeds to box 122.

[0096] At box 122 (“Heat Dissipation Calculation”), method 100 performs a heat dissipation calculation to determine the heat dissipated from the device during charging. The heat dissipation calculation can be performed by applying a first charging rate to the device over a first time period beginning with a first known battery level, and determining a predicted charging level of the device based at least in part on the first charging rate and information collected at box 114 during the first time period. The predicted charging level of the device is then compared with the actual charging level of the device. Heat dissipation can then be determined based on the comparison between the predicted and actual charging levels. With the heat dissipation calculation performed, method 100 then proceeds to box 124.

[0097] At box 124 (“Determining the charging rate”), method 100 determines the charging rate of the device based on the information above. Specifically, the charging rate can be determined based on at least one of the following: information collected at box 114, the presence of a foreign object, or heat dissipation calculations. Method 100 can then determine an acceptable charging rate based on these inputs. In one example, different inputs are evaluated in the charging rate matrix to determine the desired charging rate. For example, if the available charging duration is longer than the predicted charging duration required to fully charge the device, the method can determine that the device can be charged at a lower rate to increase battery life.

[0098] In another example, each of the above inputs is given a score, and the charging rate is determined based on the sum of the scores falling within a predetermined range. For example, when the sum of the scores exceeds the maximum value, the device's charging rate is reduced, and when the sum of the scores is below the minimum value, the device's charging rate is increased. Furthermore, the charging rate can remain constant when the scores are between the minimum and maximum values.

[0099] Once the charging rate is determined, method 100 returns to box 110 to continue monitoring for changes in foreign objects, information collected at box 114, or changes in heat dissipation, in order to determine whether the charging rate should be further modified when method 100 returns to box 124.

Unless the context clearly indicates otherwise, the term “or” means “and / or”.
