Fig. 1 is a schematic flow chart of a wireless charging method according to an embodiment of the present invention, and a detailed description will be given below, with reference to fig. 1, of a wireless charging method according to an embodiment of the present invention from a wireless charging device side, where the method includes the following steps S101 to S103.
Step S101: and receiving wireless charging parameter information of the terminal equipment to be charged.
Specifically, the wireless charging device receives wireless charging parameter information of the terminal device to be charged, where the wireless charging parameter information may be that the wireless charging device actively initiates a request when identifying the terminal device to be charged, or that the terminal device actively sends the request to the wireless charging device when the terminal device itself needs to be charged. It can be understood that the terminal device generally has a plurality of charging modes, and can perform wireless charging or wired charging, but the wireless charging device only needs to acquire the wireless charging parameter information of the terminal device.
In one possible implementation manner, the wireless charging parameter information includes at least one of a parameter related to a wireless charging receiving coil of the terminal device, a rated current, a rated voltage, a rated capacity, and a charging and discharging rate of the wireless charging of the terminal device. Since the terminal device in the present application has a wireless charging function, or the terminal device is externally connected with a device having a wireless charging function, the wireless charging parameter information includes relevant parameters of the wireless charging receiving coil, such as a coil diameter, a number of turns, a current that the wireless charging receiving coil can bear, and the like, and further includes a rated current, a voltage, a capacity, a charging and discharging rate, and the like of a charging loop of the wireless charging of the terminal device. The present invention does not limit the content specifically included in the wireless charging parameter information as long as it can be used to calculate the safe current range for wireless charging of the terminal device in step S102.
Step S102: and determining the safe current range of the wireless charging of the terminal equipment according to the wireless charging parameter information.
Specifically, the safe current range of the terminal device is determined according to the wireless charging parameters acquired in step S101, and may include the rated voltage and current of the terminal device, and the maximum tolerable voltage and current magnitude. Since the charging capacity of the terminal device is generally determined before the terminal device leaves the factory, the charging time required is longer when the charging capacity required by the terminal device is larger at the same charging current, and similarly, the charging time required is shorter when the charging current is larger. If the current provided by the wireless charging device is smaller than the rated standard current of the terminal equipment, the charging time is necessarily prolonged, and even if the current is too small, the charging cannot be carried out; similarly, when the current provided by the wireless charging device is much larger than the rated standard current of the terminal equipment, the electronic components of the terminal equipment may be broken down, that is, the charging circuit may be damaged. Therefore, it can be understood that the safe current range of the terminal device is determined, so that the wireless charging device can ensure normal charging and charging safety when the terminal device is wirelessly charged subsequently.
Step S103: and controlling and adjusting the turn-on number of the wireless charging coil in the wireless charging device so as to adjust the charging current output by the wireless charging device to be within the safe current range of the wireless charging of the terminal equipment.
Specifically, since each turn of the wireless charging coil has a magnetic flux change during the wireless charging process, an induced current is generated, and the current of the whole wireless charging coil is the sum of the currents of each turn of the coil, the more the turns of the wireless charging coil, the larger the current is. Therefore, after the safe current range of the terminal device is determined in step S102, how many turns of coils in the wireless charging coil need to be turned on currently to provide current in the safe current range for the terminal device can be calculated according to the related calculation rule, so that various different terminal devices can perform safe wireless charging on the wireless charging device in the present application. In addition, a module or a device for adjusting the number of turns on of the wireless charging coil should be provided in the wireless charging device, so as to control the turning on and off of the wireless charging coil. It can be understood that, the invention is not limited in particular to how to calculate the number of turn-on turns of the wireless charging coil corresponding to the current in the safe current range.
In order to facilitate understanding of the embodiments of the present application, the following description is made in conjunction with a wireless charging system and a specific application scenario on which the embodiments of the present application are based. As shown in fig. 2 and fig. 3, fig. 2 is a schematic view of a specific application scenario of a wireless charging method provided in an embodiment of the present application, fig. 3 is a schematic view of another specific application scenario of the wireless charging method provided in the embodiment of the present application, and in fig. 2, the architecture of the wireless charging system mainly includes a terminal device having a wireless charging function and a wireless charging device, where the wireless charging device is composed of a wireless charging adapter and a wireless charging base connected by a wire, and the terminal device performs wireless charging by being placed on the wireless charging base (i.e., within an electromagnetic range of the wireless charging adapter). It can be understood that terminal equipment and wireless charging base all have the charging coil, and the coil on the terminal equipment is the wireless receiving coil that charges of receiving terminal, and the coil on the wireless charging base is the wireless charging coil of transmitting terminal, realizes the transmission of energy through electromagnetic signal's coupling etc. between two coils. In fig. 2, the mobile phone with smaller battery capacity and rated current is charged, so the number of turns of the wireless charging coil in the corresponding wireless charging device is small, while in fig. 3, the tablet computer with larger battery capacity and rated current is charged, so the number of turns of the wireless charging coil in the corresponding wireless charging device is large. That is to say, because the charging current requirements of the mobile phone and the tablet computer are different, the mobile phone and the tablet computer can be individually charged by controlling the turn-on number of the wireless charging coil in the same wireless charging device.
It should be understood that the wireless charging system architecture based on the embodiments of the present application includes, but is not limited to, the above architecture, and the architecture to which the wireless fast charging method of the present application can be applied belongs to the protection and coverage scope of the present application.
According to the embodiment of the invention, wireless charging parameter information of the terminal equipment to be charged is received; determining a safe current range of wireless charging of the terminal equipment according to the wireless charging parameter information; and controlling and adjusting the turn-on number of the wireless charging coil in the wireless charging device so as to adjust the charging current output by the wireless charging device to be within the safe current range of the wireless charging of the terminal equipment. The safe charging current range of the terminal equipment is determined according to the wireless charging parameter information of the terminal equipment to be charged, the number of turn-on turns of the wireless charging coil in the wireless charging device is adjusted according to the range, the area of the power supply coil can be dynamically adjusted according to different charging requirements of the terminal equipment, the charging current of the terminal equipment with different requirements is ensured to be within the safe current range, the convenience and the safety of wireless charging are improved, and the user experience is improved.
Fig. 4 is a schematic flowchart of another wireless charging method provided in an embodiment of the present invention, and details of another wireless charging method in an embodiment of the present invention will be described in detail below with reference to fig. 4 from a wireless charging device side, as shown in fig. 4, the method may include the following steps S401 to S406.
Step S401: and identifying whether the terminal equipment is currently charged or not.
Specifically, the method for identifying whether the terminal device to be charged currently is to perform charging connection between the wireless charging device and the terminal device, that is, the terminal device enters a magnetic field range of the wireless charging device (a weak magnetic field signal can be maintained on a wireless charging coil of the wireless charging device when wireless charging is not actually started), the terminal device detects that charging connection is performed with the wireless charging device through a voltage change of a charging loop of the terminal device, for example, after the terminal device is placed in the magnetic field range of the wireless charging device, a voltage of the charging loop of the terminal device is divided by a resistor to obtain, for example, 1.8V, and since the charging loop is connected to a general purpose Input/Output (GPIO) port of a Central Processing Unit (CPU), when the CPU detects that the voltage of the GPIO port changes from low to high, it indicates that the terminal device is in charging connection with the wireless charging adapter. Therefore, the terminal equipment can further send an instruction to the wireless charging device in a wireless mode such as Wi-Fi, Bluetooth or infrared mode, and the like, so as to inform the current terminal equipment to be charged. It is to be understood that the wireless charging apparatus itself may identify whether the terminal device is to be charged by detecting a change in magnetic field strength or the like.
Step S402: and if so, sending a wireless charging parameter information acquisition instruction to the terminal equipment.
Specifically, after the terminal device to be charged is determined in step S401, an instruction for acquiring the wireless charging parameter information is sent to the terminal device.
Step S403: and receiving wireless charging parameter information of the terminal equipment to be charged.
Step S404: and determining the safe current range of the wireless charging of the terminal equipment according to the wireless charging parameter information.
Specifically, step S403 to step S404 refer to step S102 to step S103 in the embodiment of fig. 1, which is not described herein again.
Step S405: and acquiring the current electric quantity information of the terminal equipment.
Specifically, the current electric quantity of the terminal device is obtained in real time, so that the terminal device can be charged wirelessly more efficiently and safely.
Step S406: if the current electric quantity of the terminal equipment is smaller than a first threshold value, controlling and adjusting the turn-on number of a wireless charging coil in a wireless charging device so as to adjust the charging current output by the wireless charging device to the maximum value in the safe current range of the wireless charging of the terminal equipment.
Specifically, the current electric quantity of the terminal device is obtained, and if the current electric quantity of the terminal device is low, for example, only 10%, the terminal device can be charged with a large current, at this time, the number of turn-on turns of a wireless charging coil in the wireless charging device can be properly increased by controlling, so that the charging current of the terminal device is increased, but still needs to be controlled within a safe current range, otherwise, an electronic component is broken down due to an overlarge current, so that a circuit is burnt out.
Step S407: if the current electric quantity of the terminal equipment is larger than a second threshold value, controlling and adjusting the turn-on number of a wireless charging coil in a wireless charging device so as to adjust the charging current output by the wireless charging device to the minimum value in the safe current range of wireless charging of the terminal equipment, wherein the second threshold value is larger than or equal to the first threshold value.
Specifically, when the amount of electricity is high, for example, 90%, the charging can be performed by a smaller current in the safe current range, and at this time, the number of turns of the wireless charging coil in the wireless charging device can be controlled to be appropriately reduced, so as to reduce the charging current of the terminal device, but the charging current still needs to be controlled in the safe current range, otherwise, the charging cannot be performed due to an excessively small current.
According to the embodiment of the invention, wireless charging parameter information of the terminal equipment to be charged is received; determining a safe current range of wireless charging of the terminal equipment according to the wireless charging parameter information; and controlling and adjusting the turn-on number of the wireless charging coil in the wireless charging device so as to adjust the charging current output by the wireless charging device to be within the safe current range of the wireless charging of the terminal equipment. The safe charging current range of the terminal equipment is determined according to the wireless charging parameter information of the terminal equipment to be charged, the number of turn-on turns of the wireless charging coil in the wireless charging device is adjusted according to the range, the area of the power supply coil can be dynamically adjusted according to different charging requirements of the terminal equipment, the charging current of the terminal equipment with different requirements is ensured to be within the safe current range, the convenience and the safety of wireless charging are improved, and the user experience is improved.
