In practical applications, the charging frequency of the charging device may deviate from the resonance center frequency of the coil, and the electronic device may be charged with a second charging frequency closest to the resonance center frequency of the coil, which still allows the charging device to maintain efficient charging. However, when the charging frequency is further deviated from the resonance center frequency of the coil, the charging efficiency is lowered, and a power loss is generated between the coil of the charging device and the coil of the electronic device, but the power loss is converted into heat energy which can be used for heating the battery of the electronic device.

Fig. 3 is a schematic structural diagram of an exemplary charging circuit according to an embodiment of the present disclosure. As shown in fig. 3, in this embodiment, the charging circuit structure may include a transmitting side Integrated Circuit (IC) and a receiving side IC, and the transmitting side IC transmits power to the receiving side IC to achieve the purpose of wireless charging.
In one possible implementation, the transmitting IC is located inside the charging device and is configured to adjust a charging resonant frequency of the primary coil, and the transmitting IC may include: the device comprises a Microcontroller (MCU), a power supply module, a voltage detection circuit, a current detection circuit, a rectification circuit, a resonance circuit, a decoding circuit and a voltage regulation circuit.
Further, the MCU can output a modulation signal to the rectifying circuit and the voltage regulating circuit, the voltage regulating circuit can be used for outputting a voltage regulating signal, the rectifying circuit can be used for outputting an alternating current signal, and the resonance circuit can be used for outputting an alternating current signal to the primary coil, so that the primary coil emits current to the secondary coil. In addition, the MCU is connected to the fan and a Negative Temperature Coefficient (NTC), and when the temperature of the charging device increases and/or decreases to a preset threshold, the MCU controls the rotation speed and/or the switching of the fan by acquiring temperature information acquired by the NTC. The power supply module can be used for supplying power to the MCU, the voltage detection circuit and the current detection circuit are connected with the MCU and the rectification circuit, the voltage detection circuit can be used for detecting the voltage information of the primary coil, and the current detection circuit can be used for detecting the current information of the primary coil.
In a possible implementation, the receiving terminal IC is located inside the electronic device and is configured to control a secondary coil of the electronic device to receive the current emitted by the primary coil, and the receiving terminal IC may include: MCU, rectifier circuit and voltage regulating circuit. The functions of the MCU, the rectifying circuit and the voltage regulating circuit are the same as those of the MCU, and are not repeated herein.
Generally, the length of the standby time and the speed of charging of the electronic device depend on the activity of the battery, which is related to the temperature of the working environment of the battery, and the ideal temperature is 15 ℃ to 40 ℃. When the temperature of the working environment of the battery is low, the chemical reaction of the battery is abnormal, and the activity of the battery is deteriorated, so that the charging speed is slow, and even the charging is interrupted, and therefore, the battery needs to be heated to improve the charging efficiency of the wireless charging.
At present, the electronic device can improve the charging efficiency of wireless charging by reducing the rotation speed of the fan or turning off the fan. When the electronic device is charged, the battery temperature can be detected in real time or periodically, and the detected battery temperature is sent to the charging device, and the charging device adjusts the rotating speed of the fan or turns off the fan according to the battery temperature.
Generally, the amount of air generated by the fan is proportional to the rotational speed of the fan, i.e., the higher the rotational speed of the fan, the larger the amount of air generated, the lower the rotational speed, the smaller the amount of air generated, and the off state of the fan does not generate the amount of air. When the battery temperature of the electronic equipment is lower, the controller can reduce the rotating speed of the fan, so that the generated air volume is smaller, or the fan is closed and does not generate air volume any more, the heat dissipation of the battery of the electronic equipment is reduced, and therefore the purpose of heating the battery of the electronic equipment is achieved, and the charging efficiency of wireless charging is improved.
However, the purpose of heating the battery of the electronic device is achieved by reducing the heat dissipation of the battery of the electronic device and slowing down the temperature drop of the battery of the electronic device, and the battery heating method is slow in heating speed, so that the activity of the battery is not high, and the charging efficiency is low.
Based on the foregoing problems, embodiments of the present application provide a method, an apparatus, and a device for heating a battery, where an electronic device obtains a temperature of the electronic device, and sends a first message to a charging device when the temperature is less than a first preset value, and the charging device determines a first charging frequency according to the first message, and adjusts a charging frequency used for charging the electronic device from a second charging frequency to the first charging frequency. The difference between the first charging frequency and the coil resonance center frequency in the charging device is greater than the difference between a second charging frequency and the coil resonance center frequency in the charging device, and the second charging frequency is a frequency adopted by the charging device to charge the electronic device currently.
The coil resonance center frequency is an ideal charging frequency, and the charging efficiency of the charging equipment can be maximized at the frequency, so that the charging requirement of the electronic equipment can be met most efficiently. In practical applications, the charging frequency of the charging device may deviate from the resonance center frequency of the coil, and the electronic device may be charged with a second charging frequency closest to the resonance center frequency of the coil, which still allows the charging device to maintain efficient charging. However, when the charging frequency is further deviated from the resonance center frequency of the coil, the charging efficiency is lowered, and a power loss is generated between the coil of the charging device and the coil of the electronic device, but the power loss is converted into heat energy which can be used for heating the battery of the electronic device. The method improves the heating speed of the battery, improves the activity of the battery, and can ensure that the charging equipment can heat and charge the battery of the electronic equipment in a low-temperature environment. The specific implementation manner will be described in detail in the following embodiments, and will not be described herein again.

step 401: the electronic device acquires its own temperature.
In the embodiment of the present application, the temperature of the electronic device itself may be obtained by a temperature sensor such as an NTC, a thermocouple, or a resistance thermometer.
In one possible implementation, before acquiring the temperature of the electronic device itself, the charging device and the electronic device need to be authenticated to determine whether the charging device can charge the electronic device. And after the authentication is successful, when the electronic equipment is detected to be charged through the charging equipment, acquiring the temperature of the electronic equipment.
Illustratively, the authentication of the charging device and the electronic device is divided into two phases, the first phase being a ping phase in which the primary coil of the charging device sends a ping signal to the secondary coil of the electronic device, which ping signal may contain signal strength data packets and termination data packets. The signal strength data packet is used for indicating the coupling degree of the primary coil and the secondary coil, and the termination transmission data packet is used for indicating the charging equipment to stop transmitting the electric energy to the electronic equipment. The second phase is an identification and configuration phase in which the secondary coil of the electronic device feeds back identification and configuration data packets to the charging device in accordance with the received ping signal. The identification data packet is used for the electronic device to provide identification information, such as a product serial number, to the charging device. The configuration data packet is used for the electronic device to provide parameter configuration information, such as the maximum power required to be output by the rectifying circuit, to the charging device. After receiving the identification and configuration information fed back by the secondary coil in the electronic device, the primary coil in the charging device adjusts corresponding parameters of the primary coil, for example, adjusts a power parameter and adjusts a frequency parameter. And after the parameter adjustment is finished, the authentication is finished, and the electric energy transmission stage is entered, namely the electronic equipment is charged.
It should be understood that the electronic device may acquire its own temperature in real time or periodically. Of course, in order to reduce the power consumption of the electronic device, the temperature of the electronic device itself may be acquired when a preset condition is satisfied.
In one possible implementation, the temperature of the electronic device itself may be obtained when it is detected that the electronic device is charged by the charging device.
Specifically, when the electronic device is detected to be in the charging state, the temperature of the electronic device itself may be acquired at this time in order to avoid a phenomenon that the charging speed is slow due to a low temperature.
In another possible implementation manner, the temperature of the electronic device may be obtained by obtaining the electric quantity of the electronic device and when it is determined that the electric quantity of the electronic device is lower than the second preset value.
Specifically, when the electric quantity of the electronic device is judged to be lower than the second preset value, it is indicated that the current electronic device is low in electric quantity, and at the moment, the electronic device is charged, so that the temperature of the electronic device can be obtained, and whether a heating charging mode needs to be started for charging is judged, and the activity of a battery of the electronic device is improved.
In this mode, because when the electric quantity of electronic equipment is less than the second preset value, acquire the temperature of electronic equipment self, can in time learn the temperature condition of electronic equipment when low electric quantity from this to judge whether need open the heating charge mode, avoid because the low temperature leads to the slower phenomenon of charge speed.
In another possible implementation manner, the charging speed of the electronic device in the first time period may be obtained, and the temperature of the electronic device may be obtained when it is determined that the charging speed of the electronic device in the first time period is less than the third preset value.
Specifically, before obtaining the temperature of the electronic device itself, it may be determined whether the charging speed of the electronic device in the first time period is lower than a third preset value. For example, when the charging speed of the electronic device is lower than the third preset value within the first time period, which indicates that the charging efficiency of the electronic device is low currently, the electronic device may be in a low-temperature environment within the first time period, so that the battery activity of the electronic device is deteriorated, and the charging speed is slow, and at this time, the temperature of the electronic device itself may be obtained by the temperature sensor.
In this mode, when the charging speed of the electronic equipment is lower than the third preset value within the first time period, the temperature of the electronic equipment can be acquired, so that whether a heating charging mode needs to be started or not can be judged, the battery of the electronic equipment is heated, and the phenomenon that the charging speed is slow due to low temperature and the use of a user is influenced is avoided.
In another possible implementation manner, before obtaining the temperature of the electronic device itself, it is first required to determine whether the location information of the electronic device changes, and if it is determined that the location information of the electronic device changes, the temperature of the battery in the electronic device is obtained.
Wherein the position information can be acquired by a position sensor. For example, when the position information of the electronic device changes, the ambient temperature of the environment where the electronic device is located may also change, and therefore, the temperature of the electronic device needs to be acquired through the temperature sensor.
In this mode, when the position information of the electronic device changes, the temperature of the electronic device itself can be acquired, so that whether a heating charging mode needs to be started or not can be judged, the battery of the electronic device is heated, and the phenomenon that the charging speed is slow due to low temperature is avoided.
In another possible implementation manner, before obtaining the temperature of the electronic device itself, the screen state of the electronic device needs to be determined first, and when the screen of the electronic device is in the screen-off state, the temperature of the electronic device itself is obtained.
Illustratively, the screen states include a bright screen state and a dead screen state. When the screen state of the electronic device is the bright screen state, it indicates that the user is operating the electronic device, and the increase of the processor load may cause the temperature of the electronic device to increase, so that the battery of the electronic device may not be heated, and the temperature of the electronic device does not need to be acquired. When the screen state of the electronic equipment is the screen-off state, it indicates that the user does not operate the electronic equipment, and at this time, the load of the processor is small, and the temperature rise of the battery of the electronic equipment is not obvious. If the ambient temperature is too low, the battery cannot be charged or the charging speed is slow, so that the temperature of the electronic device can be acquired when the electronic device is in a screen-off state.
The temperature of the electronic device itself may be acquired when any of the above conditions is satisfied, or the temperature of the electronic device itself may be acquired when at least two of the above conditions are satisfied. For example, when it is detected that the electronic device is charged by the charging device, and the charging speed of the electronic device in the first time period is less than a third preset value, the temperature of the electronic device itself is acquired, and the like.
Step 402: and if the temperature is less than the first preset value, the electronic equipment sends a first message to the charging equipment.
In the embodiment of the application, for example, at a working environment temperature of 0-10 ℃, a battery of an electronic device may limit the magnitude of current due to low temperature, resulting in slow charging. At a working environment temperature of-10 to 0 ℃, the battery of the electronic equipment is disconnected and charged due to low temperature. Thus, in one possible implementation, the first preset value may be 10 ℃.
Specifically, after the temperature of the electronic device itself is obtained, it is necessary to determine whether the temperature is less than a first preset value. For example, when the temperature is lower than the first preset value, it can be understood that the electronic device is currently in a low-temperature environment, and the heating and charging mode needs to be turned on. At this time, the electronic device sends a first message to the charging device, where the first message is used to instruct the charging device to determine the first charging frequency, and adjust the charging frequency used for charging the electronic device from the second charging frequency to the first charging frequency, so as to heat the battery of the electronic device.
In a possible implementation manner, the electronic device sends received power to the charging device, where the received power is used to instruct the charging device to determine a power loss value corresponding to the charging device according to the transmission power and the received power. The power loss value corresponding to the charging equipment can be determined according to the transmitting power of the charging equipment and the receiving power of the electronic equipment, so that the third charging frequency can be timely adjusted according to the power loss value, the power loss value corresponding to the adjusted third charging frequency is in the preset range, and the situation that the power loss value exceeds the preset range to cause incapability of charging, damage to the electronic equipment and influence on use of a user is avoided.
Step 403: the charging device determines a first charging frequency according to the first message.
The difference between the first charging frequency and the coil resonance center frequency in the charging device is greater than the difference between the second charging frequency and the coil resonance center frequency in the charging device, and the second charging frequency is the frequency adopted by the charging device to charge the electronic device currently. The coil resonance center frequency is a charging frequency that maximizes charging efficiency.
Specifically, a deviation may exist between a second charging frequency adopted by the charging device when the charging device currently charges the electronic device and the coil resonance center frequency, where the deviation is a first difference value, and a deviation also exists between the first charging frequency determined by the charging device and the coil resonance center frequency, where the deviation is a second difference value, where the second difference value is greater than the first difference value. For example, the coil resonance center frequency is 135kHz, the second charging frequency is 136kHz, the determined first charging frequency is 138kHz, and the first difference is 1kHz and the second difference is 3kHz, that is, the condition that the second difference is greater than the first difference is satisfied. When the second difference is larger than the first difference, the power loss value of the charging device during charging is increased, and the part of the power loss value is converted into heat energy, so that the battery of the electronic device can be heated when the electronic device is charged by using the first charging frequency.
In addition, the second charging frequency may also be a coil resonance center frequency in the charging device. That is, the charging device currently adopts the coil resonance center frequency to charge the electronic device, and at this time, there is no difference between the second charging frequency and the coil resonance center frequency. Because the electronic equipment adopts the coil resonance center frequency to charge the electronic equipment, the charging efficiency is higher.
For example, the charging device determines the first charging frequency according to the first message, which may be determining a charging frequency range corresponding to the charging device according to the first message, and then determining the first charging frequency within the charging frequency range.
Specifically, in order to ensure that the charging device charges the electronic device stably and the charging device and the electronic device work normally, the charging device needs to determine a first charging frequency within a corresponding charging frequency range, and charge the electronic device according to the first charging frequency. In addition, the charging device comprises coils, and the corresponding charging frequency ranges of the coils are different for different coils. Illustratively, the charging frequency range corresponding to the WPC coil is 125kHz to 145kHz, and thus, the charging device may determine the first charging frequency in the 125kHz to 145kHz range.
In this embodiment of the application, the charging device determines the first charging frequency according to the first message, or may adjust the charging frequency from the second charging frequency to a third charging frequency according to the first message, then determine a power loss value corresponding to the charging device according to the third charging frequency, and determine whether the power loss value is within a preset range, and if the power loss value is within the preset range, determine the third charging frequency as the first charging frequency.
If the power loss value is not within the preset range, the third charging frequency is continuously adjusted until the power loss value corresponding to the adjusted third charging frequency is within the preset range, and the adjusted third charging frequency can be determined as the first charging frequency.
It should be noted that the third charging frequency is only a transition frequency in determining the first charging frequency, and the third charging frequency may be adjusted according to the corresponding power loss value to determine the final first charging frequency.
For example, in a specific adjustment process, the second charging frequency may be adjusted gradually to the first charging frequency in a manner of deviating from mkHz each time, where m is any positive number. In addition, each time the second charging frequency deviates, a power loss value corresponding to the deviated third charging frequency is calculated, and if the power loss value is within a preset range, the third charging frequency obtained after the deviation can be determined as the first charging frequency. If the power loss value is not within the preset range, which indicates that the power loss value is larger at this time, the obtained third charging frequency needs to be continuously adjusted until the power loss value corresponding to the adjusted third charging frequency is within the preset range, and the adjusted third charging frequency may be determined as the first charging frequency.
It is understood that, when performing the deviation, the third charging frequency obtained after the deviation may be greater than the second charging frequency, or may be smaller than the second charging frequency, and of course, the adjustment may also be performed at intervals, such as the third charging frequency obtained at the time of the first deviation is greater than the second charging frequency, and the third charging frequency obtained at the time of the second deviation is smaller than the second charging frequency … ….
For example, if the value of m is 1 and the second charging frequency is 135kHz, the charging frequency is first deviated to 136kHz, and a corresponding power loss value at 136kHz is calculated, and if the power loss value is within a preset range, 136kHz may be determined as the first charging frequency. If the power loss value is not in the preset range, the charging frequency is continuously adjusted to 137kHz, the power loss value corresponding to 137kHz is calculated, and the process is repeated until a third charging frequency with the power loss value in the preset range is determined.
For another example, if the value of m is 1 and the second charging frequency is 135kHz, the charging frequency is first deviated to 134kHz, and a corresponding power loss value at 134kHz is calculated, and if the power loss value is within a preset range, 134kHz may be determined as the first charging frequency. If the power loss value is not in the preset range, the charging frequency is continuously adjusted to 133kHz, the power loss value corresponding to 133kHz is calculated, and the process is repeated until the third charging frequency with the power loss value in the preset range is determined.
For another example, if the value of m is 1 and the second charging frequency is 135kHz, the charging frequency is first deviated to 136kHz, and a corresponding power loss value at 136kHz is calculated, and if the power loss value is within a preset range, 136kHz may be determined as the first charging frequency. If the power loss value is not within the preset range, the charging frequency is continuously adjusted to 134kHz, the power loss value corresponding to 134kHz is calculated, and the process is repeated until a third charging frequency with the power loss value within the preset range is determined.
When the offset is performed a plurality of times, the frequency values of each offset may be the same or different. For example, it may be offset by 1kHz each time, by 1kHz at the first offset, by 2kHz at the second offset, and so on.
For example, when the second charging frequency is adjusted, the third charging frequency may be adjusted at one time. For example, the second charging frequency is 135kHz and the third charging frequency is 138kHz, the charging frequency is directly biased to 138kHz during the deviation, and the third charging frequency is determined as the first charging frequency. The third charging frequency may be predetermined empirically.
Further, the preset range may be set according to experience or actual conditions, and may be, for example, 5W to 10W.
In this embodiment, when the charging frequency is adjusted, it is required to ensure that the power loss value corresponding to the adjusted charging frequency is within the preset range, so that the power loss value is ensured to be converted into heat energy to heat the electronic device, and the phenomenon that the charging efficiency is reduced due to the occurrence of too many power loss values can be avoided.
In a possible implementation manner, when the charging device determines the corresponding power loss value according to the third charging frequency, the transmitting power of the charging device may be determined according to the third charging frequency, the receiving power of the electronic device is obtained, and then the power loss value corresponding to the charging device is determined according to the transmitting power and the receiving power.
Specifically, after the charging device obtains the transmission power and the reception power, the difference between the transmission power and the reception power is determined as a power loss value. And after determining the received power according to the third charging frequency, the electronic device sends the received power of the electronic device to the charging device.
For example, when the third charging frequency is 138kHz, the transmission power of the corresponding charging device is 40W, the receiving power of the electronic device is 30W, the power loss value is 10W, and is within the preset range of power loss 5-10W, and the third charging frequency corresponding to the power loss may be determined as the first charging frequency.
In this embodiment, the charging device may determine the power loss value corresponding to the charging device according to the acquired transmission power and the acquired reception power, so that the accuracy of the determined power loss value may be higher.
In a possible implementation manner, the IC of the charging device may adjust the magnitude of the transmission power according to the third charging frequency, and when the charging device receives the first message, the charging device may appropriately increase the transmission power within a preset range to increase the power loss value, so that more power loss values may be converted into heat energy to accelerate heating of the battery of the electronic device, thereby increasing the heating speed of the battery, and further increasing the charging efficiency of the electronic device at a low temperature.
Step 404: the charging device adjusts the charging frequency used for charging the electronic device from the second charging frequency to the first charging frequency so as to heat the battery of the electronic device.
In this step, since the second charging frequency is the charging frequency when the charging device is in the normal charging mode, the charging device generates less power loss at this time. If the battery of the electronic device needs to be heated to reach the temperature range in which the battery normally works, the charging device needs to generate more heat, and the heat can be converted from power loss according to the principle of energy conservation. The charging frequency can thus be offset from the second charging frequency, which is adjusted to the first charging frequency. In this way, after the charging frequency of the charging device is adjusted from the second charging frequency to the first charging frequency, a part of power loss is generated, and the part of power loss is converted into heat, so that the battery of the electronic device can be heated.
In a possible implementation manner, in order to timely monitor the temperature of the electronic device and avoid the battery performance from being damaged due to the overhigh temperature of the heated battery, the electronic device may real-time or periodically perform its own temperature during the process that the charging device heats the battery of the electronic device in the manner described above. If the obtained temperature information is larger than the fourth preset value, the electronic equipment sends a second message to the charging equipment, and the charging equipment executes preset operation according to the second message to stop heating the battery of the electronic equipment. The preset operation may include any one of the following operations: and adopting the second charging frequency to charge the electronic equipment, reducing the transmitting power of the charging equipment, or stopping charging the electronic equipment.
Specifically, after the charging device adjusts the adopted charging frequency from the second charging frequency to the first charging frequency and heats the battery of the electronic device, the temperature of the electronic device itself may increase. In the heating process, the electronic device can acquire temperature information in real time or periodically through the temperature sensor, and when the temperature is higher than a fourth preset value, the electronic device can send a second message to the charging device, so that the charging device stops heating the battery of the electronic device.
For example, the fourth preset value may be 20 ℃, because the ideal operating temperature range of the battery is 15 ℃ to 40 ℃, at which the battery of the electronic device can operate normally and the temperature does not cause the external part of the electronic device to be scalded.
Furthermore, after the charging device receives the second message, the charging device can execute preset operation to stop heating the battery of the electronic device, so that the electronic device can be prevented from being scalded due to overhigh temperature of the battery, and the user experience is not influenced.
In one possible implementation manner, the charging device may restore the charging frequency from the first charging frequency to the second charging frequency, and continue to charge the electronic device using the second charging frequency.
Illustratively, in a particular recovery process, the first charging frequency may be adjusted stepwise toward the second charging frequency in a manner of mkHz per recovery, where m is any positive number. In the process of gradual recovery, the frequency value of each recovery may be the same or different. For example, 1kHz may be recovered each time, or 1kHz may be recovered at the first recovery, 2kHz may be recovered at the second recovery, and so on until the second charging frequency is recovered, and the second charging frequency is determined as the charging frequency of the current electronic device after the recovery is completed.
For example, in a specific recovery process, the first charging frequency may also be adjusted to the second charging frequency at one time. For example, if the first charging frequency is 138kHz and the second charging frequency is 135kHz, the charging frequency is directly restored to 135kHz during the restoration process, and the second charging frequency is determined as the charging frequency of the current electronic device after the restoration is finished.
Therefore, when the charging equipment continues to adopt the second charging frequency for charging, the power loss value is small, the converted heat energy is small, and therefore the battery of the electronic equipment is stopped from being heated and charged, and the phenomenon that the battery performance is damaged due to the fact that the battery of the electronic equipment is too high in temperature can be avoided. In addition, since the charging device is restored to the normal charging mode to charge the electronic device, and the temperature of the battery in the electronic device is high at this time, the electric energy can be efficiently received, so that the charging efficiency is high.
In another possible implementation, the charging device may reduce the power loss value by reducing the transmission power. Therefore, the charging equipment can reduce the generated heat energy so as to slow down the temperature rise of the battery in the electronic equipment, thereby avoiding the damage of the battery performance due to overhigh temperature.
In yet another possible implementation manner, the charging device may stop heating the battery of the electronic device by turning off the power supply to stop charging the electronic device, so that the battery performance may be prevented from being damaged due to too high temperature, and electric energy may be saved.
