[0048] like Figure 1 As shown, the application scenario of the present invention involves wireless charging of an electric bicycle by a wireless charging pile, a wireless transmitter is installed in the wireless charging pile, a wireless receiver is installed in the electric bicycle, and the wireless receiver is installed in a kickstand of the electric bicycle. When the electric bicycle is wirelessly charged, the kickstand of the electric bicycle is placed in a wireless sensing area in the wireless charging pile. At this time, the wireless transmitter and the wireless receiver establish electromagnetic coupling to realize the transmission of electric energy. The electric energy is transmitted from the wireless transmitter to the wireless receiver. The wireless receiver is connected to the battery of the electric bicycle inside the electric bicycle to realize the charging of the battery of the electric bicycle.
[0049] Figure 2 It is a structural diagram of a wireless transmitter and a wireless receiver, such as Figure 2 As shown, the wireless transmitting end includes an oscillator, a phase shift control circuit and a transmitting coil, and the wireless receiving end includes a receiving coil and a converter. The wireless transmitting end and the wireless receiving end realize power transmission including: the oscillator generates a high-frequency signal within a specific frequency range, the phase shift control circuit adjusts the phase of the high-frequency signal, thereby affecting the electromagnetic field characteristics of the transmission, and the current output by the phase shift control circuit flows into the transmitting coil, and a magnetic field is generated inside the transmitting coil through the current, and the energy is emitted in the form of electromagnetic waves. The receiving coil in the wireless receiving end captures the electromagnetic waves from the wireless transmitting end and converts them into alternating current. The converter converts the received alternating current into the required direct current, which is injected into the battery of the electric bicycle to charge the battery.
[0050] This embodiment provides a wireless charging control method, device, electronic device and storage medium.
[0051] Figure 3 A flowchart of a wireless charging control method provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, a wireless charging control method provided by an embodiment of the present invention is applied to a wireless transmitting end in the above application environment, wherein the wireless transmitting end is used to transmit electric energy to a wireless receiving end in an electric bicycle through wireless transmission, so that the wireless receiving end charges the battery of the electric bicycle, including:
[0052] S100, acquiring charging data in a wireless receiving end collected by a post-stage sampling circuit, wherein the post-stage sampling circuit is arranged in the wireless receiving end.
[0053] Specifically, the post-stage sampling circuit generally includes multiple sensors, including a voltage sensor, a current sensor and a temperature sensor. The voltage sensor is used to detect the voltage charged into the battery during the charging process, the current sensor is used to detect the current charged into the battery during the charging process, and the temperature sensor is used to detect the temperature of the battery connected to the receiving end. The charging data includes the voltage collected by the voltage sensor, the current collected by the current sensor and / or the temperature sampled by the temperature sensor.
[0054] The post-stage sampling circuit arranged in the wireless receiving end performs sampling at predetermined intervals (sampling period) to obtain charging data. The charging data after each sampling will be sent to the wireless transmitting end through the communication module in the wireless receiving end. The wireless transmitting end receives the charging data sent by the communication module in the wireless receiving end, that is, obtains the charging data in the wireless receiving end collected by the post-stage sampling circuit.
[0055] S200, adjusting a control signal of the wireless transmitter according to the charging data, wherein the control signal is used to control a phase shift control circuit in the wireless transmitter to control an output current of the wireless transmitter.
[0056] Specifically, the phase shift control circuit changes the phase of the signal input to the phase shift control circuit, and the phase shift control circuit adjusts the phase of the input signal (current signal) and thus adjusts the output voltage of the wireless transmitter. By changing the control signal, the components being adjusted (such as switches, capacitors, inductors, or using digital signal processors, etc.) can be adjusted to achieve dynamic adjustment of the output voltage of the wireless transmitter. The output current of the wireless transmitter corresponds to Figure 2 The output current of the phase shift control circuit in the middle, the output current of the phase shift control circuit (recorded as the first output current) flows into the transmitting coil, generates a magnetic field inside the transmitting coil, and sends electromagnetic waves to the wireless receiving end. The receiving coil in the wireless receiving end captures the electromagnetic waves from the wireless transmitting end and converts them into alternating current. The converter converts the received alternating current into direct current. The current and voltage corresponding to the direct current are the voltage and current charged into the battery during the charging process, that is, the output voltage (recorded as the second output voltage) and the output current (recorded as the second output current) of the wireless receiving end. The phase shift control circuit can be implemented by a full-bridge or half-bridge topology structure. The topology of the phase shift control circuit is a prior art and will not be described here.
[0057] When the modulation mode of the converter in the wireless receiving end remains unchanged, the output current of the phase shift control circuit is positively correlated with the output voltage and output current of the wireless receiving end, that is, the larger the first output current is, the larger the second output voltage and the second output current are, and conversely, the smaller the first output current is, the smaller the second output voltage and the second output current are.
[0058] By adjusting the control signal, the output current of the wireless transmitter is adjusted. The change of the output current of the wireless transmitter causes the change of the output voltage and output current of the wireless receiver, thereby realizing the control of the charging data of the wireless receiver.
[0059] In this embodiment, when the wireless transmitting end is transmitting electric energy to the wireless receiving end, the wireless transmitting end obtains the charging data in the wireless receiving end collected by the post-stage sampling circuit, and adjusts the control signal in the control phase shift control circuit according to the charging data. As the control signal changes and adjusts, the output current of the wireless transmitting end also changes accordingly, thereby causing the charging data in the wireless receiving end to change. That is, in this embodiment, the control signal of the wireless transmitting end is adjusted by the charging data, and the charging data is adjusted according to the adjustment of the control signal, forming a closed loop of the charging data, thereby realizing precise control of the charging data for charging the battery in the wireless receiving end, and achieving the effect of controlling the charging data of the wireless receiving end to keep stable when charging the battery.
[0060] Optionally, adjusting the control signal of the wireless transmitting end according to the charging data includes: determining the charging state of the wireless receiving end; when the charging state is constant voltage charging, adjusting the control signal according to voltage data in the charging data; when the charging state is constant current charging, adjusting the control signal according to current data in the charging data.
[0061] Specifically, when adjusting the control signal of the wireless transmitting end, the charging state of the wireless receiving end is first determined. The charging state of the wireless receiving end includes two types: constant current charging state and constant voltage charging state. Generally, when charging the battery of an electric bicycle, the battery is charged using constant current charging in the early stage of charging, especially when the battery power is low. In the late stage of charging, that is, when the battery is about to be fully charged, the constant current charging state is switched to the constant voltage charging state. In the constant current charging state, the wireless receiving end provides a constant current to the battery, that is, the current data of the charging data in the wireless receiving end is constant, and the battery power can be quickly charged to a higher level, which is suitable for fast charging requirements; in the constant voltage charging state, the wireless receiving end applies a constant voltage to the battery, and the wireless receiving end keeps the voltage unchanged, and the charging current will gradually decrease as the battery state changes.
[0062] When the charging state is constant voltage charging, the control signal will be adjusted according to the voltage data in the received charging data to keep the charging voltage provided by the wireless receiving end to the battery stable.
[0063] When the charging state is constant current charging, the control signal will be adjusted according to the current data in the received charging data to keep the charging current provided by the wireless receiving end to the battery stable.
[0064] Optionally, adjusting the control signal according to the voltage data in the charging data includes: when the voltage data is greater than a first preset voltage value, reducing the duty cycle of the control signal; when the voltage data is less than the first preset voltage value, increasing the duty cycle of the control signal.
[0065] Specifically, the first preset voltage value is a preset reference value. In the constant voltage charging state, the voltage provided by the wireless receiving end to the battery of the electric bicycle needs to be stable around the reference value.
[0066] The duty cycle of the control signal refers to the ratio of the time the control signal is at a high level to the entire cycle in one cycle. Adjusting the duty cycle can change the output voltage or current of the phase shift control circuit, thereby changing the voltage and current provided by the wireless receiving end to the battery.
[0067] When the voltage data is greater than the first preset voltage value, it is necessary to reduce the voltage provided by the wireless receiving end to the battery of the electric bicycle, and the voltage provided by the wireless receiving end to the battery is reduced by reducing the duty cycle of the control signal.
[0068] When the voltage data is less than the first preset voltage value, it is necessary to increase the voltage provided by the wireless receiving end to the battery of the electric bicycle, and to increase the duty cycle of the control signal to thereby increase or decrease the voltage provided by the wireless receiving end to the battery.
[0069] When the voltage data is equal to the first preset voltage value, there is no need to adjust the voltage provided by the wireless receiving end to the battery of the electric bicycle, that is, there is no need to adjust the duty cycle of the control signal of the wireless transmitting end.
[0070] Optionally, adjusting the control signal according to current data in the charging data includes:
[0071] When the current data is greater than a first preset current value, reducing the duty cycle of the control signal;
[0072] When the current data is less than the first preset current value, the duty cycle of the control signal is increased.
[0073] Specifically, the first preset current value is a preset reference value. In the constant voltage charging state, the current provided by the wireless receiving end to the battery of the electric bicycle needs to be stable around the reference value.
[0074] The duty cycle of the control signal refers to the ratio of the time the control signal is at a high level to the entire cycle in one cycle. Adjusting the duty cycle can change the output voltage or current of the phase shift control circuit, thereby changing the voltage and current provided by the wireless receiving end to the battery.
[0075] When the current data is greater than the first preset current value, it is necessary to reduce the current provided by the wireless receiving end to the battery of the electric bicycle, and the current provided by the wireless receiving end to the battery is reduced by reducing the duty cycle of the control signal.
[0076] When the current data is less than the first preset current value, it is necessary to increase the current provided by the wireless receiving end to the battery of the electric bicycle, and increase the duty cycle of the control signal to increase the current provided by the wireless receiving end to the battery.
[0077] When the current data is equal to the first preset current value, there is no need to adjust the current provided by the wireless receiving end to the battery of the electric bicycle, that is, there is no need to adjust the duty cycle of the control signal.
[0078] Optionally, before acquiring the charging data in the wireless receiving end collected by the post-stage sampling circuit, the wireless charging control method further includes: controlling the wireless transmitting end to establish a communication connection with the wireless receiving end; and receiving the charging data sent by the post-stage sampling circuit to the wireless transmitting end through the communication connection.
[0079] Specifically, since the wireless transmitter and the wireless receiver are generally two independent devices, when the wireless transmitter and the wireless receiver are in contact, the wireless receiver can only sense the magnetic field through the receiving coil to receive the electric energy transmitted by the wireless transmitter, but only through the magnetic field, the wireless receiver and the wireless transmitter cannot transmit data other than electric energy, that is, only through the magnetic field generated by the transmitter, the wireless transmitter cannot obtain the power supply data of the wireless transmitter collected by the post-stage sampling circuit.
[0080] Therefore, in this embodiment, a stable communication connection needs to be established between the wireless transmitter and the wireless receiver in order to exchange charging data in real time. After the communication connection is established, the data transmission phase begins. In this phase, the wireless receiver sends the charging data collected by the post-stage sampling circuit to the wireless transmitter through the established communication connection. The above communication connection can be a radio frequency communication connection, an infrared communication connection, a Bluetooth communication connection, a Wi-Fi communication connection, etc.
[0081] Optionally, the wireless charging control method further includes: acquiring power supply data in the wireless transmitting end collected by a front-stage sampling circuit, wherein the front-stage sampling circuit is arranged in the wireless transmitting end; and adjusting the control signal according to the charging data and the power supply data.
[0082] Specifically, Figure 4 As shown, when adjusting the control signal, in addition to adjusting the control signal according to the charging data collected by the post-stage sampling circuit arranged in the wireless receiving end, the control signal can also be adjusted according to the power supply data in the wireless transmitting end.
[0083] The front-stage sampling circuit at least includes a current sensor, and the current sensor is used for the output current of the wireless transmitting end.
[0084] Optionally, adjusting the control signal according to the charging data and the power supply data includes:
[0085] When the current data in the power supply data is greater than a second preset current value or the voltage data in the power supply data is greater than a second preset voltage value, adjusting the control signal according to the power supply data;
[0086] When the current data in the power supply data is less than or equal to the second preset current value, and the voltage data in the power supply data is less than or equal to the second preset voltage value, the control signal is adjusted according to the charging data.
[0087] Specifically, in addition to adjusting the control signal according to the charging data in the wireless receiving end, it is also necessary to consider whether the output current generated at the wireless transmitting end has the risk of overcurrent or overvoltage. When the current data in the power supply data (i.e., corresponding to the output current generated by the wireless transmitting end) is greater than the second preset current value, or the voltage data in the power supply data (i.e., corresponding to the output voltage generated by the wireless transmitting end) is greater than the second preset voltage value, it may cause overload or other potential electrical problems. Adjusting the control signal according to the power supply data can specifically be to reduce the duty cycle of the control signal to reduce the output current or output current of the wireless transmitting end.
[0088] If the current data in the power supply data (i.e., corresponding to the output current generated by the wireless transmitting end) is less than the second preset current value, and the voltage data in the power supply data is less than the second preset voltage value, there will be no risk of overcurrent or overvoltage. The current data of the wireless receiving end can be controlled to remain at the target value (first preset voltage value), and the control signal can be adjusted according to the charging data.
