Description

Technical Field

[0001] The present invention belongs to the field of wireless charging technology, and specifically relates to a wireless charging mobile power energy saving management method, device, equipment, medium and product. Background Art

[0002] Portable power banks (power banks) have become essential in our daily lives. As one of the main types of portable power banks, wireless power banks are devices that contain a built-in battery and utilize wireless charging technology (derived from wireless power transmission technology, which primarily operates on the principle of an induction cooker: when current passes through a coil, a magnetic field is generated; this magnetic field, in turn, creates a voltage, which in turn generates a current, which in turn allows charging) to provide electrical energy.

[0003] Because wireless power banks have limited internal storage energy, energy-saving management is necessary. Existing patent CN111371145A provides a control method for wireless power banks and a wireless power bank. The control method includes: when the wireless power bank is in an energy-saving state, confirming that an external wireless receiving device is within a preset wireless charging area and generating a trigger signal; switching the wireless power bank from the energy-saving state to the operating state based on the trigger signal; establishing protocol communication between the wireless power bank and the wireless receiving device, and transmitting wireless charging power to the wireless receiving device. While the aforementioned patented technology enables the wireless power bank to automatically activate the wireless charging function, bringing convenience and improving the user experience, it does not address energy-saving management after the wireless charging function is activated. Consequently, if the wireless charging transmission efficiency remains too low after the wireless charging function is activated, a large amount of energy will be lost and wasted. Therefore, how to effectively manage the energy-saving of the wireless power bank even after the wireless charging function is activated to avoid energy loss and waste is a topic that those skilled in the art urgently need to study. Summary of the Invention

[0004] The object of the present invention is to provide a method, apparatus, control device, computer-readable storage medium, and computer program product for energy-saving management of a wireless charging mobile power supply, which can be used to effectively manage the energy saving of the wireless charging mobile power supply even after the wireless charging function is turned on, so as to avoid loss and waste of electric energy.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] In a first aspect, a method for energy-saving management of a wireless charging mobile power supply is provided, which is executed by a main control module in the wireless charging mobile power supply, wherein the wireless charging mobile power supply further includes an induction module, a wireless communication module, a wireless charging transmitter module, and a power storage module, wherein an output end of the induction module and the wireless communication module are respectively communicatively connected to the main control module, the main control module is further communicatively connected to a controlled end of the wireless charging transmitter module, and the power storage module is respectively electrically connected to the main control module, the induction module, the wireless communication module, and the wireless charging transmitter module;

[0007] The wireless charging mobile power energy saving management method includes:

[0008] When the wireless charging mobile power supply is in the energy-saving state, if a wireless charging trigger signal is received from the sensing module and is used to indicate that an external wireless receiving device is located within a preset wireless charging area, the wireless charging mobile power supply is switched from the energy-saving state to the working state;

[0009] After the wireless charging mobile power supply is in the working state, establishing a long connection with the external wireless receiving device through the wireless communication module;

[0010] Upon receiving a wireless charging request from the external wireless receiving device, sending a battery monitoring data query request to the external wireless receiving device through the wireless communication module, and receiving initial battery monitoring data fed back by the external wireless receiving device;

[0011] transmitting wireless charging energy to the external wireless receiving device via the wireless charging transmitting module according to the initial battery monitoring data;

[0012] Periodically sending the battery monitoring data query request to the external wireless receiving device through the wireless communication module, and receiving new battery monitoring data fed back by the external wireless receiving device;

[0013] Calculate the wireless charging transmission efficiency in the most recent cycle based on the two most recently received consecutive battery monitoring data.

[0014] If it is determined that the wireless charging transmission efficiency in the most recent cycle is lower than the preset efficiency threshold, the transmission of wireless charging energy to the external wireless receiving device is stopped.

[0015] Based on the above invention, a new solution for energy-saving management of a wireless charging mobile power supply after the wireless charging function is turned on is provided. The solution is executed by a main control module in the wireless charging mobile power supply. After the wireless charging mobile power supply is in an operating state, a long connection with an external wireless receiving device is first established through the wireless communication module. Then, initial battery monitoring data is accessed and requested and wireless charging energy is transmitted to the receiving device based on the data. Then, new battery monitoring data is periodically requested. Based on the two most recent consecutive battery monitoring data received, the wireless charging transmission efficiency in the most recent cycle is calculated. Finally, when the transmission efficiency is found to be lower than a preset efficiency threshold, the transmission of wireless charging energy is terminated. In this way, low wireless charging transmission efficiency can be detected in a timely manner and charging can be terminated, thereby achieving the purpose of effective energy-saving management of the wireless charging mobile power supply even after the wireless charging function is turned on, thereby avoiding loss and waste of electric energy and facilitating practical application and promotion.

[0016] In one possible design, the wireless charging mobile power supply further includes a transmitting coil translation module for translating the transmitting coil in the wireless charging transmitting module, wherein a controlled end of the transmitting coil translation module is communicatively connected to the main control module, and the power storage module is also electrically connected to the transmitting coil translation module;

[0020] At the end of the third cycle, for each of the three most recent consecutive cycles, the internal resistance of the wireless charging receiving-side battery in the corresponding cycle is first calculated based on the two battery monitoring data received before and after the corresponding cycle. The internal resistance of the wireless charging receiving-side battery, the wireless charging output voltage, and the wireless charging transmission efficiency in the corresponding cycle are then input into a first mapping model to output a corresponding coil alignment deviation distance. A three-point positioning method is then used to determine the position of the receiving coil in the external wireless receiving device within the preset wireless charging area based on the initial position, the first position, the second position, and the coil alignment deviation distances corresponding to each cycle. Finally, the transmitting coil translation module is used to translate the transmitting coil from the second position within the coil active area to a third position for alignment with the position of the receiving coil within the preset wireless charging area. The first mapping model is used to reflect the functional relationship between the internal resistance of the wireless charging receiving-side battery, the wireless charging output voltage, and the wireless charging transmission efficiency and the coil alignment deviation distance, where the coil alignment deviation distance refers to the deviation distance that needs to be eliminated to achieve alignment between the transmitting coil and the receiving coil.

[0022] The transmitting coil is translated from a current position within the coil active area to a fourth position by the transmitting coil translation module;

[0023] At the end of the next cycle, the transmitting coil is translated from the fourth position to a fifth position within the coil active area by the transmitting coil translation module, wherein the fifth position is different from the current position;

[0024] At the end of the next new cycle, for each of the three most recent consecutive cycles, first, based on the two battery monitoring data received before and after the corresponding cycle, calculate the internal resistance of the wireless charging receiving-side battery in the corresponding cycle, then import the wireless charging receiving-side battery internal resistance, the wireless charging output voltage, and the wireless charging transmission efficiency in the corresponding cycle into the first mapping model to output a corresponding coil alignment deviation distance, and then, based on the current position, the fourth position, the fifth position, and the coil alignment deviation distances corresponding to each new cycle, use the three-point positioning method to determine a new position of the receiving coil within the preset wireless charging area, and finally, use the transmitting coil translation module to translate the transmitting coil from the fifth position within the coil active area to a sixth position for alignment with the new position of the receiving coil within the preset wireless charging area.

[0025] If it is determined that the wireless charging transmission efficiency in the new current most recent cycle is still lower than the preset efficiency threshold, the transmission of wireless charging energy to the external wireless receiving device is stopped.

[0026] In one possible design, after terminating the transmission of wireless charging energy to the external wireless receiving device, the wireless charging mobile power supply energy saving management method further includes:

[0027] Switching the wireless charging mobile power supply from the working state to the energy-saving state;

[0028] After at least one cycle, the wireless charging mobile power supply is switched from the energy-saving state to the working state, and the battery monitoring data query request is sent to the external wireless receiving device through the wireless communication module, and new battery monitoring data fed back by the external wireless receiving device is received;

[0031] Calculating the wireless charging transmission efficiency in the next cycle based on the two battery monitoring data received before and after the next cycle;

[0032] If it is determined that the wireless charging transmission efficiency in the next cycle is still lower than the preset efficiency threshold, the transmission of wireless charging energy to the external wireless receiving device is stopped again.

[0033] In one possible design, after the transmission of wireless charging energy to the external wireless receiving device is stopped again, the wireless charging mobile power supply energy saving management method further includes:

[0034] If it is determined that the number of consecutive times of suspending the transmission of wireless charging energy to the external wireless receiving device has reached a preset threshold, the transmission of wireless charging energy to the external wireless receiving device is terminated, the long connection with the external wireless receiving device is disconnected, and the wireless charging mobile power supply is switched from the working state to the energy-saving state.

[0035] In one possible design, for each of the three most recent consecutive cycles, the internal resistance of the wireless charging receiving side battery in the corresponding cycle is calculated based on the two battery monitoring data received before and after the corresponding cycle, including:

[0036] For each of the three most recent consecutive cycles, first, based on the two battery monitoring data received before and after the corresponding cycle, the average battery power of the wireless charging receiving side, the average battery voltage of the wireless charging receiving side, and the average battery temperature of the wireless charging receiving side in the corresponding cycle are statistically obtained, and then the average battery power of the wireless charging receiving side, the average battery voltage of the wireless charging receiving side, and the average battery temperature of the wireless charging receiving side are imported into the second mapping model, and the internal resistance of the wireless charging receiving side battery in the corresponding cycle is output, wherein the second mapping model is used to reflect the functional relationship between the battery power, battery voltage, battery temperature and the battery internal resistance.

[0038] The wireless charging mobile power energy saving management device includes a trigger signal receiving unit, a long connection establishing unit, a monitoring data transceiver unit, a charging transmission control unit and a transmission efficiency calculation unit;

[0039] The trigger signal receiving unit is configured to, when the wireless charging mobile power supply is in the energy-saving state, switch the wireless charging mobile power supply from the energy-saving state to the working state upon receiving a wireless charging trigger signal from the sensing module indicating that an external wireless receiving device is located within a preset wireless charging area;

[0040] The long connection establishing unit is communicatively connected to the trigger signal receiving unit, and is used to establish a long connection with the external wireless receiving device through the wireless communication module after the wireless charging mobile power supply is in the working state;

[0042] The charging transmission control unit is communicatively connected to the monitoring data transceiver unit, and is used to transmit wireless charging energy to the external wireless receiving device through the wireless charging transmission module according to the initial battery monitoring data;

[0043] The monitoring data transceiver unit is further configured to periodically send the battery monitoring data query request to the external wireless receiving device through the wireless communication module, and receive new battery monitoring data fed back by the external wireless receiving device;

[0044] The transmission efficiency calculation unit is communicatively connected to the monitoring data transceiver unit and is used to calculate the wireless charging transmission efficiency in the most recent cycle based on the battery monitoring data received twice in a row;

[0045] The charging transmission control unit is also communicatively connected to the transmission efficiency calculation unit, and is further configured to stop transmitting wireless charging energy to the external wireless receiving device when it is determined that the wireless charging transmission efficiency in the current most recent cycle is lower than a preset efficiency threshold.

[0049] Beneficial effects of the above scheme:

[0050] (1) The present invention creatively provides a new solution for energy-saving management of a wireless charging mobile power supply after the wireless charging function is turned on, that is, the solution is executed by a main control module in the wireless charging mobile power supply, and after the wireless charging mobile power supply is in a working state, first a long connection is established with an external wireless receiving device through a wireless communication module, and then initial battery monitoring data is accessed and requested and wireless charging energy is transmitted to the receiving device accordingly, and then new battery monitoring data is periodically requested, and the wireless charging transmission efficiency in the current most recent cycle is calculated based on the battery monitoring data received twice in a row, and finally the transmission of wireless charging energy is stopped when it is found that the transmission efficiency is lower than a preset efficiency threshold, so that the low wireless charging transmission efficiency can be detected in time and charging can be stopped, thereby achieving the purpose of effective energy-saving management of the wireless charging mobile power supply even after the wireless charging function is turned on, thereby avoiding the loss and waste of electric energy;

[0051] (2) After the wireless charging function is turned on, the position of the receiving coil in the preset wireless charging area can be determined in a timely manner, and the transmitting coil can be driven to align with it.

[0052] (3) When the wireless charging transmission efficiency is found to be too low, the wireless charging transmission efficiency can be improved by re-determining the position of the receiving coil within the preset wireless charging area and driving the transmitting coil to align with it. Finally, charging is terminated only when the wireless charging transmission efficiency is still too low. This can also avoid accidental termination of charging and ensure charging efficiency.

[0053] (4) It can also automatically resume charging after charging is suspended, so that charging can be resumed in time when the fault of low transmission efficiency is eliminated (for example, after the battery temperature is reduced and restored), further ensuring charging efficiency and facilitating practical application and promotion.

[0061] Example

[0062] like Figure 1As shown, the energy-saving management method for a wireless charging mobile power supply provided in the first aspect of this embodiment can be executed by, but is not limited to, a main control module with certain computing resources and in a wireless charging mobile power supply. The wireless charging mobile power supply further includes, but is not limited to, an induction module, a wireless communication module, a wireless charging transmitter module, and a power storage module. The output end of the induction module and the wireless communication module are respectively connected to the main control module in communication. The main control module is also connected to the controlled end of the wireless charging transmitter module in communication. The power storage module is respectively electrically connected to the main control module, the induction module, the wireless communication module, and the wireless charging transmitter module. The induction module is used to detect in real time whether an external wireless receiving device (such as a smartphone or tablet with wireless charging function) is located in a preset wireless charging area. If so, it transmits a wireless charging trigger signal to the main control module indicating that an external wireless receiving device is located in the preset wireless charging area. The induction module can be obtained by making conventional modifications to the induction module in the existing patent CN111371145A. The wireless communication module is used to wirelessly communicate with the external wireless receiving device. It can be implemented by, but is not limited to, a Bluetooth module. The wireless charging transmitter module is used to transmit wireless charging energy to the external wireless receiving device via an internal transmitting coil under the control of the main control module. It can be obtained by conventionally modifying the wireless charging transmitter module described in the existing patent CN111371145A. In addition, the power storage module can be implemented by, but is not limited to, a lithium battery.

[0063] like Figure 1 As shown, the energy-saving management method of the wireless charging mobile power supply includes but is not limited to the following steps S1 to S7.

[0064] S1. When the wireless charging mobile power supply is in the energy-saving state, if a wireless charging trigger signal is received from the sensing module and is used to indicate that an external wireless receiving device is located within a preset wireless charging area, the wireless charging mobile power supply is switched from the energy-saving state to the working state.

[0065] In the step S1, the wireless charging trigger signal may be, but is not limited to, a high level signal or a low level signal.

[0066] S2. After the wireless charging mobile power supply is in the working state, a long connection is established with the external wireless receiving device through the wireless communication module.

[0067] In step S2, the long connection means that the connection established between the client (i.e., the external wireless receiving device in this embodiment) and the server (i.e., the wireless charging mobile power supply in this embodiment) will not be closed immediately after one communication, but will be maintained for a period of time, allowing multiple requests / responses to be made on the same connection, so it can be established and maintained based on existing session technology.

[0068] S3. Upon receiving a wireless charging request from the external wireless receiving device, sending a battery monitoring data query request to the external wireless receiving device via the wireless communication module, and receiving initial battery monitoring data fed back by the external wireless receiving device.

[0069] In step S3, the initial battery monitoring data is the battery monitoring data before transmitting wireless charging energy, specifically including but not limited to battery power, battery voltage and battery temperature, etc., which can be collected in real time by an application such as a battery manager or Power Battery installed on the external wireless receiving device.

[0070] S4. Transmitting wireless charging energy to the external wireless receiving device through the wireless charging transmitting module according to the initial battery monitoring data.

[0071] In step S4, the specific process of transmitting wireless charging energy according to the initial battery monitoring data is a conventional technical means, such as selecting a suitable wireless charging mode according to the battery power: performing wireless fast charging when the battery power is low, and performing wireless slow charging when the battery power is high.

[0072] S5. Periodically send the battery monitoring data query request to the external wireless receiving device through the wireless communication module, and receive new battery monitoring data fed back by the external wireless receiving device.

[0073] In step S5, the battery monitoring data query request is sent for a period of, for example, but not limited to, one minute. The new battery monitoring data is the battery monitoring data after transmitting wireless charging energy, specifically including but not limited to battery level, battery voltage, battery temperature, and the power consumption of the external wireless receiving device in the most recent cycle. These data can also be collected in real time by an application such as a battery manager or Power Battery installed on the external wireless receiving device.

[0074] S6. Calculate the wireless charging transmission efficiency in the most recent cycle based on the two most recently received consecutive battery monitoring data.

[0075] In step S6, since, in the two most recently received consecutive battery monitoring data, the first received battery monitoring data packet contains the battery power, and the second received battery monitoring data packet contains the battery power and the power consumption of the external wireless receiving device in the most recent cycle, and the main control module can conventionally collect the output power of the wireless charging mobile power supply in the most recent cycle, the wireless charging transmission efficiency η in the most recent cycle can be specifically calculated according to the following formula:

[0076]

[0077] Where p i Indicates the battery power in the previously received battery monitoring data, p a Indicates the battery power in the battery monitoring data received later, p u Indicates the power consumption of the external wireless receiving device in the most recent cycle in the battery monitoring data received later, p out Indicates the output power of the wireless charging mobile power bank in the most recent cycle.

[0078] S7. If it is determined that the wireless charging transmission efficiency in the current most recent cycle is lower than the preset efficiency threshold, the transmission of wireless charging energy to the external wireless receiving device is stopped.

[0079] In step S7, the preset efficiency threshold may be specifically pre-set according to the wireless charging capability of the wireless charging mobile power supply, for example, set to 85%.

[0080] Based on the energy-saving management method for a wireless charging mobile power supply described in steps S1 to S7, a new solution for energy-saving management of a wireless charging mobile power supply after the wireless charging function is turned on is provided. The solution is executed by a main control module in the wireless charging mobile power supply. After the wireless charging mobile power supply is in an operating state, a long connection is first established with an external wireless receiving device through the wireless communication module. Then, initial battery monitoring data is accessed and requested, and wireless charging energy is transmitted to the receiving device based on the data. Then, new battery monitoring data is periodically requested, and the wireless charging transmission efficiency in the most recent cycle is calculated based on the two most recently received consecutive battery monitoring data. Finally, when the transmission efficiency is found to be lower than a preset efficiency threshold, the transmission of wireless charging energy is terminated. In this way, low wireless charging transmission efficiency can be detected in a timely manner and charging can be terminated, thereby achieving the purpose of effective energy-saving management of the wireless charging mobile power supply even after the wireless charging function is turned on, thereby avoiding energy loss and waste, and facilitating practical application and promotion.

[0081] Based on the technical solution of the first aspect, this embodiment further provides a possible design for improving wireless charging transmission efficiency. Specifically, the wireless charging mobile power supply further includes a transmitting coil translation module for translating the transmitting coil in the wireless charging transmitting module. The controlled end of the transmitting coil translation module is communicatively connected to the main control module, and the power storage module is also electrically connected to the transmitting coil translation module. The transmitting coil translation module specifically includes, but is not limited to, an X-axis linear reciprocating motion mechanism and a Y-axis linear reciprocating motion mechanism. The X-axis linear reciprocating motion mechanism is mounted on the moving portion of the Y-axis linear reciprocating motion mechanism, and the transmitting coil is mounted on the moving portion of the X-axis linear reciprocating motion mechanism. Thus, translation of the transmitting coil can be achieved through conventional drive control of the X-axis linear reciprocating motion mechanism and the Y-axis linear reciprocating motion mechanism. After transmitting wireless charging energy to the external wireless receiving device via the wireless charging transmitting module based on the initial battery monitoring data, the wireless charging mobile power supply energy saving management method further includes, but is not limited to, the following steps S41 to S43.

[0082] S41. At the end of the first cycle, the transmitting coil is translated from an initial position within the coil active area to a first position by the transmitting coil translation module, wherein a plane of the coil active area is parallel to a plane of the preset wireless charging area.

[0083] S42. At the end of the second cycle, the transmitting coil is translated from the first position to a second position within the coil active area by the transmitting coil translation module, wherein the second position is different from the initial position.

[0084] S43. At the end of the third cycle, for each of the three most recent consecutive cycles, first calculate the internal resistance of the wireless charging receiving-side battery within the corresponding cycle based on the two battery monitoring data received before and after the corresponding cycle, then import the wireless charging receiving-side battery internal resistance, the wireless charging output voltage, and the wireless charging transmission efficiency within the corresponding cycle into a first mapping model to output a corresponding coil alignment deviation distance. Then, based on the initial position, the first position, the second position, and the coil alignment deviation distances corresponding to each cycle, a three-point positioning method is used to determine the position of the receiving coil in the external wireless receiving device within the preset wireless charging area. Finally, the transmitting coil translation module is used to translate the transmitting coil from the second position within the coil active area to a third position for alignment with the position of the receiving coil within the preset wireless charging area. The first mapping model is used to reflect the functional relationship between the wireless charging receiving-side battery internal resistance, the wireless charging output voltage, and the wireless charging transmission efficiency and the coil alignment deviation distance, where the coil alignment deviation distance refers to the deviation distance that needs to be eliminated to achieve alignment between the transmitting coil and the receiving coil.

[0085] In step S43, since the battery charge, battery voltage, and battery temperature each have a certain physical relationship with the battery internal resistance, specifically, for each of the three most recent consecutive cycles, the internal resistance of the wireless charging receiving-side battery in the corresponding cycle is first calculated based on the two battery monitoring data received before and after the corresponding cycle, including but not limited to: for each of the three most recent consecutive cycles, first, based on the two battery monitoring data received before and after the corresponding cycle, statistically obtaining the average battery charge of the wireless charging receiving-side battery in the corresponding cycle (e.g., the average of the two battery charges before and after), the average battery voltage of the wireless charging receiving-side battery (e.g., the average of the two battery voltages before and after), and the average battery temperature of the wireless charging receiving-side battery (e.g., the average of the two battery temperatures before and after), and then importing the average battery charge of the wireless charging receiving-side battery, the average battery voltage of the wireless charging receiving-side battery, and the average battery temperature of the wireless charging receiving-side battery into a second mapping model to output the internal resistance of the wireless charging receiving-side battery in the corresponding cycle, wherein the second mapping model is used to reflect the functional relationship between the battery charge, battery voltage, and battery temperature and the battery internal resistance. The second mapping model can be specifically constructed by a conventional fitting method based on a certain amount of test data (i.e., test results of battery power, battery voltage, battery temperature, and battery internal resistance). Since the internal resistance of the battery on the wireless charging receiving side, the wireless charging output voltage (which can be conventionally collected on the wireless charging transmitting side), the vertical distance between the transmitting coil and the receiving coil (i.e., the distance between the plane where the coil active area is located and the plane where the preset wireless charging area is located, which is a fixed value and can be ignored when constructing the first mapping model), and the alignment deviation distance have a certain physical connection with the wireless charging transmission efficiency, the first mapping model can be constructed by a conventional fitting method based on a certain amount of other test data (i.e., test results of the battery internal resistance on the wireless charging receiving side, wireless charging output voltage, coil alignment deviation distance, and wireless charging transmission efficiency). In addition, the three-point positioning method is an existing positioning algorithm and will not be described in detail here.

[0086] Based on the aforementioned possible design one, after the wireless charging function is turned on, the position of the receiving coil within the preset wireless charging area can be promptly determined, and the transmitting coil can be driven to align with it. The automatic alignment of the coils can then effectively improve the wireless charging transmission efficiency, further avoiding the loss and waste of energy.

[0087] Based on the technical solution of the aforementioned possible design one, this embodiment also provides a possible design two for remediating and improving the wireless charging transmission efficiency when it is found that the wireless charging transmission efficiency is too low, that is, terminating the transmission of wireless charging energy to the external wireless receiving device, including but not limited to the following steps S71 to S74.

[0088] S71. Use the transmitting coil translation module to translate the transmitting coil from a current position within the coil active area to a fourth position.

[0089] S72. At the end of the next cycle, the transmitting coil translation module translates the transmitting coil from the fourth position to a fifth position within the coil active area, wherein the fifth position is different from the current position.

[0090] S73. At the end of the next new cycle, for each new cycle in the three most recent consecutive cycles, first calculate the internal resistance of the wireless charging receiving side battery in the corresponding cycle based on the two battery monitoring data received before and after the corresponding cycle, then import the internal resistance of the wireless charging receiving side battery as well as the wireless charging output voltage and wireless charging transmission efficiency in the corresponding cycle into the first mapping model, and output the corresponding coil alignment deviation distance; then, based on the current position, the fourth position, the fifth position and the coil alignment deviation distances corresponding to each new cycle, use the three-point positioning method to determine the new position of the receiving coil in the preset wireless charging area; finally, use the transmitting coil translation module to translate the transmitting coil from the fifth position in the coil active area to the sixth position for aligning with the new position of the receiving coil in the preset wireless charging area.

[0091] In the step S73, the specific technical details can be conventionally derived with reference to the aforementioned step S43 and will not be described in detail here.

[0092] S74. If it is determined that the wireless charging transmission efficiency in the new current most recent cycle is still lower than the preset efficiency threshold, stop transmitting wireless charging energy to the external wireless receiving device.

[0093] Based on the aforementioned possible design 2, when the wireless charging transmission efficiency is found to be too low, the wireless charging transmission efficiency can be improved by re-determining the position of the receiving coil within the preset wireless charging area and driving the transmitting coil to align with it. Finally, charging is terminated only when it is found that the wireless charging transmission efficiency is still too low. This can also avoid accidental termination of charging and ensure charging efficiency.

[0094] Based on the technical solution of the first aspect, this embodiment further provides a third possible design for resuming charging after charging is suspended. That is, after suspending the transmission of wireless charging energy to the external wireless receiving device, the wireless charging mobile power supply energy saving management method further includes but is not limited to the following steps S81 to S86.

[0095] S81. Switch the wireless charging mobile power supply from the working state to the energy-saving state.

[0096] S82. After at least one cycle, the wireless charging mobile power supply is switched from the energy-saving state to the working state, and the battery monitoring data query request is sent to the external wireless receiving device through the wireless communication module, and new battery monitoring data fed back by the external wireless receiving device is received.

[0097] S83. Transmit wireless charging energy to the external wireless receiving device through the wireless charging transmitting module according to the new battery monitoring data.

[0098] S84. At the end of the next cycle, the battery monitoring data query request is sent to the external wireless receiving device through the wireless communication module, and new battery monitoring data fed back by the external wireless receiving device is received.

[0099] S85. Calculate the wireless charging transmission efficiency in the next cycle based on the two battery monitoring data received before and after the next cycle.

[0100] S86. If it is determined that the wireless charging transmission efficiency in the next cycle is still lower than the preset efficiency threshold, the transmission of wireless charging energy to the external wireless receiving device is stopped again.

[0101] Specifically, in step S86, after the wireless charging energy transmission to the external wireless receiving device is suspended again, the wireless charging mobile power supply energy saving management method further includes, but is not limited to, if it is determined that the number of consecutive suspensions of wireless charging energy transmission to the external wireless receiving device has reached a preset threshold, terminating the wireless charging energy transmission to the external wireless receiving device, disconnecting the long connection with the external wireless receiving device, and switching the wireless charging mobile power supply from the working state to the energy saving state. The preset threshold is, for example, but not limited to, three times.

[0102] Therefore, based on the aforementioned possible design three, charging can also be automatically resumed after charging is suspended, so that charging can be resumed in time when the fault of low transmission efficiency is eliminated (for example, after the battery temperature is reduced and recovered), thereby further ensuring charging efficiency.
