Detailed Description
The following describes in detail a specific implementation of a charging control method and a charging circuit according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to charge a plurality of devices to be charged simultaneously, a plurality of interfaces are provided in a charger in the prior art, and different devices to be charged are charged through different interfaces. However, the charger with a plurality of built-in interfaces cannot meet the demand of people for quick charging. Therefore, in order to solve the above problems in the prior art, the present application provides a charging device and a charging method, where the method and the device are based on the same inventive concept, and because the principles of the method and the device for solving the problems are similar, the implementation of the device and the method can be referred to each other, and repeated details are not repeated.
It should be noted that, in the description of the embodiments of the present application, in the description of the present application, "a plurality" means two or more; the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.
The charging equipment and the charging method are suitable for a scene that the wireless charging equipment in a wireless charging system performs wireless charging on the equipment to be charged and a scene that the wired charging equipment in a wired charging system performs wired charging on the equipment to be charged, and are particularly suitable for a scene that the charging equipment simultaneously charges a plurality of equipment to be charged. Fig. 1 shows a charging system structure to which the charging device, the charging apparatus, and the charging method provided in the present application are applied, where the charging system 100 includes a charging apparatus 101 and a device to be charged 102 that supports a charging function.
As shown in fig. 2a, for a wireless charging device, a charging device 101 is connected to a power supply 200 through a charging device 300, and is configured to send energy of the power supply to the device to be charged through a sending end 211 in an electromagnetic wave manner; and the equipment to be charged is used for receiving the electromagnetic wave and charging the equipment to be charged by the energy carried by the electromagnetic wave. The transmitting end 211 may be a coil or other device for transmitting electromagnetic waves. As shown in fig. 2b, for a wired charging device, the wired charging device may be connected to a power supply through a charging port 201 and send the wired charging device to the device to be charged; the device to be charged obtains the energy of the power supply through the charging port 201 to charge itself. The charging port 201 may be a USB interface, or may select another interface according to needs, which is not limited herein.
As shown in fig. 3, an embodiment of the present invention provides a charging device, which includes a control unit 310 and a plurality of charging units 301, and the charging units 311 and 313 are illustrated in fig. 3 as an example; one end of the charging unit 301 is provided with a charging port, and the other end of the charging unit is electrically connected with the control unit 310;
the charging unit 301 is configured to detect a device to be charged through the charging port;
the control unit 310 is configured to charge the device to be charged according to the charging priorities of the charging units 311 and 313.
As shown in fig. 3, the device to be charged 1 is connected to the charging port of the charging unit 313, and the device to be charged 2 is connected to the charging port of the charging unit 312, and the control unit 310 is configured to charge the device to be charged 1 and the device to be charged 2 according to the charging priorities of the respective charging units 312 and 313.
The control unit 310 may be located outside the charging unit 301 or inside the charging unit 301. When the control unit 310 is located in the charging unit 301, it may be specifically located in the charging unit 311, or located in the charging unit 312, or located in the charging unit 313. The control unit 310 may be a Micro Controller Unit (MCU) or a Central Processing Unit (CPU). In addition, the control unit 310 may also be connected to a memory for storing program instructions and data necessary for the charging device 300 to perform charging.
By adopting the above scheme, the charging method and the charging device provided by the embodiment of the invention comprise a control unit and a plurality of charging units; one end of the charging unit is provided with a charging port, and the other end of the charging unit is electrically connected with the control unit; the charging unit is used for detecting equipment to be charged through the charging port; the control unit is used for charging the equipment to be charged according to the charging priority of each charging unit; the priority can be set according to the charging requirement, so that the charging equipment has a wide application range and strong universality.
In a possible implementation manner, the control unit is further configured to set a charging priority of each charging unit.
For example, the charging units may be prioritized in an order, e.g., the priority of the charging unit 311 is greater than the priority of the charging unit 312, and the priority of the charging unit 312 is greater than the priority of the charging unit 313. The setting rule may be a default rule of factory shipment or may be set by a user as required.
In a setting mode, a possible implementation mode is that the charging device further comprises an operation and control part, wherein the operation and control part is used for receiving a user priority setting instruction; the control unit is also used for determining the charging priority of each charging unit according to the control piece.
Specifically, a setting key may be preset on the charging device, or a touch screen may be provided on the charging device, as shown in fig. 4, in the display interface, a setting interface may be displayed for setting the priority of each charging unit. And after the control unit acquires the priority set by the user or the manufacturer, the control unit sets the priority for each charging unit.
In another possible implementation manner, the setting priority of each charging unit can be adjusted according to the personal use habit of the user. For example, if it is determined that the charging unit commonly used by the user is 313, the priority of the charging unit 313 is increased, and if it is determined that the time for accessing the charging device to the device to be charged exceeds the preset threshold, the priority of the charging unit accessed to the charging device is decreased, so that the charging device preferentially charges the device accessed to the charging device and with short time.
Of course, the setting rule may be set by the user for each charging unit according to the usage habit. For example, the charging unit 311 is set as a common charging unit, i.e., the priority of the charging unit 311 is set to be higher, or the charging unit 312 is set as a rapid charging unit, i.e., the priority of the charging unit 312 is set to be highest, the charging unit 313 is set as a backup charging unit, and the priority of the charging unit 312 is set to be lowest.
In the actual charging process, the control unit 310 may further adjust the priority of the charging unit corresponding to the device to be charged according to the actual electric quantity of the device to be charged.
In a possible implementation manner, the charging unit 301 is configured to detect an electric quantity of the device to be charged through the charging port, and send the electric quantity of the device to be charged to the control unit;
the control unit 310 is further configured to determine a charging priority of each charging unit according to the electric quantity of each device to be charged.
For example, if it is determined that the amount of electricity of the device to be charged 2 detected by the charging port corresponding to the charging unit 312 is 50%; the electric quantity of the device to be charged 1 detected by the charging port corresponding to the charging unit 313 is 20%; the control unit 310 may adjust the charging priority of the charging unit 312 to be smaller than the charging priority of the charging unit 313 according to the amount of power of the devices to be charged 1 and 2.
With reference to the foregoing embodiments, the control unit may also determine the priority of the charging unit according to the charging mode of different devices to be charged.
In a possible implementation manner, the control unit 310 is configured to determine N first charging units with the highest priority, and perform charging in a first mode for a device to be charged externally connected to the control unit through the N first charging units; charging in a second mode is carried out on the equipment to be charged which is externally connected with the charging unit through other charging units; the charging efficiency of the first mode is higher than that of the second mode; and N is a positive integer.
For example, if it is determined that the priority of the charging unit 313 is the highest, that is, the first charging unit includes the charging unit 313, the device to be charged 1 on the charging unit 313 performs the charging in the first mode; the device to be charged 2 performs charging in the second mode. The first mode may be a high voltage fast charge mode; the second mode may be a low voltage and/or low current slow charge mode. Of course, the first mode may also be a fast charging mode in which the charging voltage or the charging current is adjusted in real time according to the device to be charged.
In a possible implementation manner, the control unit is configured to determine N first charging units with the highest priority, and charge, through the N first charging units, a device to be charged externally connected to the control unit;
the control unit is used for reducing the charging priority of the N first charging units when the electric quantity of the equipment to be charged externally connected with the N first charging units reaches a threshold value, so that other charging units charge the equipment to be charged externally connected with the charging units; the threshold is set by the control unit for each charging unit.
With reference to the above embodiment, the priority of charging unit 313 is the highest, and the priority of charging unit 313 is lower, charging unit 313 is charged preferentially. In the charging process, if it is determined that the electric quantity of the device to be charged 2 detected by the charging port corresponding to the charging unit 312 is 50%; the electric quantity of the device to be charged 1 detected by the charging port corresponding to the charging unit 313 is 70%; it is determined that the amount of power of the device to be charged 1 reaches the threshold value, the charging priority of the charging unit 313 may be lowered, and the charging unit 312 is charged preferentially.
In a specific implementation process, the threshold may be set according to each charging unit, that is, may be set according to a priority of each charging unit, or may be set to the same value, which is not limited herein. For example, the amount of electricity corresponding to the end of the current phase in the charging phase is set as a threshold.
In a possible implementation, as shown in fig. 5, the charging unit 311 may further include a first expansion interface 510, where the first expansion interface 510 may include a plurality of expansion interfaces 5101 and 5103, the number is not limited, and 3 are taken as an example here; the first expansion interface 510 can form a channel for communicating with the charging unit 311 after being docked. The control unit 310 can also obtain the charging current and the charging voltage of the first expansion interface 510 through the channel to adjust the priority of the expansion interfaces 5101 and 5103 in the first expansion interface 510. Similarly, the charging unit 312 further includes a second expansion interface, and the control unit 310 may further obtain a charging current and a charging voltage of the second expansion interface through a channel to adjust a priority of the second expansion interface. Other charging units may also refer to the embodiment of the charging unit with an extended interface, which is not limited herein.
The first expansion interface 510 and the second expansion interface may adopt but are not limited to any one of a contact interface, an embedded interface, and a snap-in interface.
In a possible embodiment, as shown in fig. 6, the charging unit 311 may further include a first expansion interface 510, and before the first expansion interface 510 forms a channel for communicating with the charging unit 311, a switch 513 is further included, and whether to access the first expansion interface 510 may be controlled by the switch.
The charging device further includes a power interface through which current from an external power source is supplied to the charging unit 301.
Of course, when two or more charging units in the charging unit 301 may have power interfaces respectively, the charging unit 301 may supply power to other charging units in the charging device through any one charging unit having a power interface.
In a possible implementation manner, the charging device may further include a rechargeable power supply, and the built-in battery may serve as a power supply to charge the device to be charged.
Under the control of the first controller, the rechargeable power supply is charged by electric energy obtained from the external power supply through the power supply interface;
when there is no external power supply to supply power to the charging unit 301 and the charging unit 301 needs to charge the device to be charged or the device to be charged, the charging unit 301 is supplied with power by using the electric energy stored in the rechargeable power supply.
The first electric energy conversion circuit and the rechargeable power supply which are included in the charging unit 301 enable the charging unit to provide electric energy for the charging unit when the charging unit is not connected with an external power supply, and therefore a user can wirelessly charge the charging unit without a power supply or an inconvenient power supply connection in the scene without the power supply nearby, and user experience can be improved.
