[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following further elaborates on the embodiments of the present disclosure in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely used to explain the embodiments of the present disclosure and are not used to limit the embodiments of the present disclosure.

[0026] First, before specifically introducing the technical solutions of the embodiments of the present disclosure, the technical background or the evolution context based on which the embodiments of the present disclosure are described is introduced. With the development of technology, shared transportation tools such as shared bicycles and shared power-assisted bicycles have emerged in the market, providing great convenience for people's lives. Currently, shared bicycles usually use solar panels to charge the battery, so that the battery powers control components such as the vehicle lock. In some scenarios, such as rainy or cloudy days with less sunlight, or when the solar panel is blocked, the charging power of the solar panel is insufficient, which easily leads to low battery power problems for shared bicycles. In addition, it should be noted that the applicant has put in a lot of creative labor from determining the need to improve the charging power of the solar panel and the technical solutions introduced in the following embodiments.

[0027] Next, in conjunction with the scenarios to which the embodiments of the present disclosure are applied, the technical solutions involved in the embodiments of the present disclosure are introduced.

[0028] The charging control method provided by the embodiments of the present disclosure can be applied to an application environment as Figure 1 shown. This application environment includes a vehicle, which can be a shared two-wheeled vehicle such as a shared bicycle or a shared electric vehicle. The vehicle includes a charging main board 101, a solar panel 102, and a battery 103. The solar panel 102 can convert light energy into electrical energy, the charging main board 101 can control the solar panel 102 to charge the battery 103, and the battery 103 can power the components that need electricity in the vehicle.

[0029] In one embodiment, as Figure 2 shown, a charging control method is provided. Taking the charging main board in Figure 1 as an example, the method includes the following steps:

[0030] Step 201, detect the first charging current output by the solar panel.

[0031] After initialization, the charging main board of the vehicle can detect the output current of the solar panel to obtain the first charging current. The detection methods can include: setting a detection resistor on the path between the solar panel and the charging main board, obtaining the resistor voltage of the detection resistor, and calculating the first charging current based on the resistor voltage and the resistance value. The detection methods can also include: setting a current detection circuit at the output end of the solar panel, and the charging main board obtains the first charging current from this current detection circuit.

[0032] It should be noted that the current detection method is not limited to the above description. In actual applications, other detection methods can also be used.

[0033] Step 202: According to the first charging current and the preset current threshold, increase or decrease the charging voltage threshold of the battery, and detect the second charging current output by the solar panel.

[0034] The output current of the solar panel reflects the photoelectric conversion situation of the solar panel to a certain extent. In a scenario with strong light, the output current of the solar panel is large; in a scenario with weak light, the output current of the solar panel is small. Currently, a fixed charging voltage threshold is usually used to control the charging of the battery by the solar panel. However, in the case of weak light, the output voltage of the solar panel cannot reach the charging voltage threshold, and the solar panel will not charge the battery. In response to this situation, the embodiments of the present disclosure adopt a method of dynamically adjusting the charging voltage threshold, that is, according to the first charging current and the preset current threshold, to determine whether the solar panel is in a scenario with strong light or a scenario with weak light.

[0035] In a scenario with weak light, the charging voltage threshold can be appropriately decreased. In this way, the output voltage of the solar panel can easily reach the charging voltage threshold, and the solar panel can also charge the battery in a scenario with weak light, thereby extending the charging duration of the solar panel; and after decreasing the charging voltage threshold, the output current of the solar panel will increase, and the charging power of the solar panel can be increased.

[0036] In a scenario with strong light, the charging voltage threshold can be appropriately increased. In this way, the output voltage of the solar panel will increase, and the charging power of the solar panel can also be increased.

[0037] After adjusting the charging voltage threshold, the output current of the solar panel is detected again to obtain the second charging current. The specific detection method can refer to the above embodiments.

[0038] Step 203: According to the second charging current and the preset current threshold, control the solar panel to charge the battery according to the adjusted charging voltage threshold.

[0039] After detecting the second charging current, the charging scenario is confirmed again according to the second charging current and the preset current threshold. If it is confirmed that the charging scenario has not changed, then control the solar panel to charge the battery according to the adjusted charging voltage threshold. If the charging scenario changes, corresponding charging measures are taken.

[0040] It should be noted that the preset current threshold and the charging current threshold in the embodiments of the present disclosure can be set according to actual situations. For example, the preset current threshold is 200 mA, and the charging voltage threshold is 5.1 V.

[0041] In the above embodiments, the first charging current output by the solar panel is detected; according to the first charging current and a preset current threshold, the charging voltage threshold of the battery is decreased or increased, and the second charging current output by the solar panel is detected; according to the second charging current and the preset current threshold, the solar panel is controlled to charge the battery according to the adjusted charging voltage threshold. In the embodiments of the present disclosure, the charging scenario is determined based on the output current of the solar panel, and the charging voltage threshold is dynamically adjusted according to the charging scenario. In both the case of weak light and strong light, the charging power of the solar panel can be increased, thereby reducing the risk of the battery running out of power.

[0042] In one embodiment, the step of decreasing or increasing the charging voltage threshold of the battery according to the first charging current and the preset current threshold may include: when the first charging current is less than the preset current threshold, decreasing the charging voltage threshold; when the first charging current is greater than or equal to the preset current threshold, increasing the charging voltage threshold.

[0043] In the embodiments of the present disclosure, after the first charging current is detected, the first charging current is compared with the preset current threshold. If the first charging current is less than the preset current threshold, it indicates that the solar panel is in a scenario of weak light, and then the charging voltage threshold is decreased. For example, if the charging voltage threshold is defaulted to 5.1V and the first charging current is less than 200 mA, the charging voltage threshold is decreased to 4.3V. In this way, the output voltage of the solar panel reaches 4.3V to charge the battery.

[0044] If the first charging current is greater than or equal to the preset current threshold, it indicates that the solar panel is in a scenario of strong light, and then the charging voltage threshold is increased. For example, if the charging voltage threshold is defaulted to 5.1V and the first charging current is greater than or equal to 200 mA, the charging voltage threshold is increased to 6V. In this way, the output voltage of the solar panel reaches 6V to charge the battery. Since the charging voltage is relatively high, the charging power of the solar panel is also relatively high.

[0045] In the above embodiments, when the first charging current is less than the preset current threshold, the charging voltage threshold is decreased; when the first charging current is greater than or equal to the preset current threshold, the charging voltage threshold is increased. In the embodiments of the present disclosure, decreasing the charging voltage threshold in the scenario of weak light and increasing the charging voltage threshold in the scenario of strong light can both increase the charging power of the solar panel, thereby charging the battery faster and reducing the risk of the battery running out of power; moreover, the charging duration of the solar panel in the scenario of weak light can be extended, and the risk of the battery running out of power can also be reduced.

[0046] In one embodiment, after reducing the charging voltage threshold, the step of controlling the solar panel to charge the battery according to the adjusted charging voltage threshold based on the second charging current and the preset current threshold may include: when the second charging current is less than the preset current threshold, controlling the solar panel to charge the battery according to the reduced charging voltage threshold.

[0047] After reducing the charging voltage threshold, reconfirm the charging scenario, that is, compare the second charging current output by the solar panel with the preset current threshold. If the second charging current is less than the preset current threshold, it indicates that the solar panel is still in a scenario with weak light, then control the solar panel to charge the battery according to the reduced charging voltage threshold. For example, if the second charging current is less than 200 mA, control the solar panel to charge the battery according to the reduced 4.3 V.

[0048] Based on the above embodiment, the embodiment of the present disclosure may further include: when the second charging current is greater than or equal to the preset current threshold, restore the charging voltage threshold to the default value, and after a preset duration, return to execute the step of detecting the first charging current output by the solar panel.

[0049] If the second charging current is greater than or equal to the preset current threshold, it indicates that the charging scenario of the solar panel has changed. It is possible that the solar panel has transferred from a scenario with weak light to a scenario with strong light. Then first restore the charging voltage threshold to the default value, and then detect the output current of the solar panel again after a preset duration to obtain the first charging current, and rejudge the charging scenario of the solar panel according to the first charging current.

[0050] For example, if the second charging current is greater than or equal to 200 mA, restore the charging voltage threshold from 4.3 V to 5.1 V, detect the first charging current again after an interval of 4 s, and rejudge whether to adjust the charging voltage threshold according to the first charging current and 200 mA.

[0051] It should be noted that the preset duration of the interval can be set according to the actual situation.

[0052] In the above embodiment, after reducing the charging voltage threshold, when the second charging current is less than the preset current threshold, control the solar panel to charge the battery according to the reduced charging voltage threshold; when the second charging current is greater than or equal to the preset current threshold, restore the charging voltage threshold to the default value, and after a preset duration, return to execute the step of detecting the first charging current output by the solar panel. In the embodiment of the present disclosure, after reducing the charging voltage threshold, reconfirm the charging scenario, and take corresponding measures according to the reconfirmed result. In this way, the accuracy of the charging voltage threshold can be improved, thereby improving the charging power of the solar panel.

[0053] In one embodiment, after raising the charging voltage threshold, the step of controlling the solar panel to charge the battery according to the adjusted charging voltage threshold based on the second charging current and the preset current threshold may include: when the second charging current is greater than or equal to the preset current threshold, controlling the solar panel to charge the battery according to the raised charging voltage threshold.

[0054] After raising the charging voltage threshold, confirm the charging scenario again, that is, compare the second charging current output by the solar panel with the preset current threshold. If the second charging current is greater than or equal to the preset current threshold, it indicates that the solar panel is still in a scenario with strong light, then control the solar panel to charge the battery according to the raised charging voltage threshold. For example, if the second charging current is greater than or equal to 200 mA, then control the solar panel to charge the battery according to the raised 6 V.

[0055] Based on the above embodiment, the embodiment of the present disclosure may further include: when the second charging current is less than the preset current threshold, restore the charging voltage threshold to the default value, and return to execute the step of detecting the first charging current output by the solar panel.

[0056] If the second charging current is less than the preset current threshold, it indicates that the charging scenario of the solar panel has changed. It is possible that the solar panel has transferred from a scenario with strong light to a scenario with weak light. Then first restore the charging voltage threshold to the default value, then detect the output current of the solar panel again after a preset time interval to obtain the first charging current, and re-judge the charging scenario of the solar panel according to the first charging current.

[0057] For example, if the second charging current is less than 200 mA, then restore the charging voltage threshold from 6 V to 5.1 V, detect the first charging current again after an interval of 4 s, and re-judge whether to adjust the charging voltage threshold according to the first charging current and 200 mA.

[0058] In the above embodiment, after raising the charging voltage threshold, when the second charging current is greater than or equal to the preset current threshold, control the solar panel to charge the battery according to the raised charging voltage threshold; when the second charging current is less than the preset current threshold, restore the charging voltage threshold to the default value, and return to execute the step of detecting the first charging current output by the solar panel. In the embodiment of the present disclosure, after raising the charging voltage threshold, reconfirm the charging scenario, and take corresponding measures according to the reconfirmation result. In this way, the accuracy of the charging voltage threshold can be improved, thereby improving the charging power of the solar panel.

[0059] In one embodiment, after controlling the solar panel to charge the battery according to the adjusted charging voltage threshold, the embodiment of the present disclosure may further include: charging for a preset duration, and returning to execute the step of detecting the second charging current output by the solar panel.

[0060] During the charging process, control the solar panel to charge the battery according to the reduced charging voltage threshold. After continuously charging for a preset duration, re-detect the output current of the solar panel to obtain a second charging current, and then confirm again whether the charging scenario of the solar panel has changed based on the second charging current and the preset current threshold.

[0061] Similarly, control the solar panel to charge the battery according to the increased charging voltage threshold. After continuously charging for a preset duration, re-detect the output current of the solar panel to obtain a second charging current, and then confirm again whether the charging scenario of the solar panel has changed based on the second charging current and the preset current threshold.

[0062] If the charging scenario does not change, continue charging for a preset duration; if the charging scenario changes, restore the charging voltage threshold and re-detect the charging scenario of the solar panel.

[0063] In the above embodiments, the charging preset duration is set, and the step of detecting the second charging current output by the solar panel is returned. In the embodiments of the present disclosure, during the charging process, the charging scenario is repeatedly confirmed, and the charging voltage threshold can be dynamically adjusted to make the charging voltage threshold more matched with the charging scenario, so that the solar panel can better charge the battery, thereby reducing the risk of the battery running out of power.

[0064] In one embodiment, a charging control method is provided. Taking the charging main board in Figure 1 as an example for illustration, the method includes the following steps:

[0065] Step 1, detect the first charging current output by the solar panel.

[0066] Compare the first charging current with the preset current threshold, and perform Step 2 or Step 5 according to the comparison result.

[0067] Step 2, in the case where the first charging current is less than the preset current threshold, reduce the charging voltage threshold and detect the second charging current output by the solar panel.

[0068] Compare the second charging current with the preset current threshold, and perform Step 3 or Step 4 according to the comparison result.

[0069] Step 3, in the case where the second charging current is less than the preset current threshold, control the solar panel to charge the battery according to the reduced charging voltage threshold.

[0070] Step 4, in the case where the second charging current is greater than or equal to the preset current threshold, restore the charging voltage threshold to the default value, and after a preset duration, return to perform the step of detecting the first charging current output by the solar panel.

[0071] Step 5, when the first charging current is greater than or equal to the preset current threshold, increase the charging voltage threshold and detect the second charging current output by the solar panel.

[0072] Compare the second charging current with the preset current threshold, and perform Step 6 or Step 7 according to the comparison result.

[0073] Step 6, when the second charging current is greater than or equal to the preset current threshold, control the solar panel to charge the battery according to the increased charging voltage threshold.

[0074] Step 7, when the second charging current is less than the preset current threshold, restore the charging voltage threshold to the default value and return to execute the step of detecting the first charging current output by the solar panel.

[0075] Step 8, charge for a preset duration and return to execute the step of detecting the second charging current output by the solar panel.

[0076] For a specific example, refer to Figure 3 .

[0077] In the above embodiments, the charging main board repeatedly confirms the charging scenario according to a preset period, can dynamically adjust the charging voltage threshold to make the charging voltage threshold more matched with the charging scenario, so that the solar panel can better charge the battery, thereby reducing the risk of the battery running out of power.

[0078] It should be understood that although Figures 2 to 3 the steps in the flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, Figures 2 to 3 at least a part of the steps in

[0079] In one embodiment, as Figure 4 shown, a charging control device is provided, including:

[0080] A current detection module 301 that detects the first charging current output by the solar panel;

[0081] A voltage threshold adjustment module 302 that reduces or increases the charging voltage threshold of the battery according to the first charging current and the preset current threshold, and detects the second charging current output by the solar panel;

[0082] The charging module 303 is configured to control the solar panel to charge the battery according to the adjusted charging voltage threshold based on the second charging current and a preset current threshold.

[0083] In one embodiment, the voltage threshold adjustment module 302 is specifically configured to lower the charging voltage threshold when the first charging current is less than the preset current threshold; and raise the charging voltage threshold when the first charging current is greater than or equal to the preset current threshold.

[0084] In one embodiment, after lowering the charging voltage threshold, the charging module 303 is specifically configured to control the solar panel to charge the battery according to the lowered charging voltage threshold when the second charging current is less than the preset current threshold.

[0085] In one embodiment, the device further includes:

[0086] The threshold recovery module is configured to restore the charging voltage threshold to the default value when the second charging current is greater than or equal to the preset current threshold, and return to execute the step of detecting the first charging current output by the solar panel after a preset duration.

[0087] In one embodiment, after raising the charging voltage threshold, the charging module 303 is specifically configured to control the solar panel to charge the battery according to the raised charging voltage threshold when the second charging current is greater than or equal to the preset current threshold.

[0088] In one embodiment, the threshold recovery module is further configured to restore the charging voltage threshold to the default value when the second charging current is less than the preset current threshold, and return to execute the step of detecting the first charging current output by the solar panel.

[0089] In one embodiment, after controlling the solar panel to charge the battery according to the adjusted charging voltage threshold, the device further includes:

[0090] The repeated detection module is configured to charge for a preset duration and return to execute the step of detecting the second charging current output by the solar panel.

[0091] For the specific limitations of the charging control device, reference may be made to the limitations of the charging control method in the foregoing text, which will not be elaborated herein. Each module in the above charging control device can be implemented in whole or in part by software, hardware, and their combination. The above modules can be embedded in the processor of the electronic device in hardware form or be independent of it, or stored in the memory of the electronic device in software form, so that the processor can call and execute the operations corresponding to the above respective modules.

[0092] In one embodiment, as Figure 1As shown, a vehicle is provided. The vehicle includes a charging main board 101, a solar panel 102, and a battery 103. The charging main board 101 is respectively connected to the solar panel 102 and the battery 103. The charging main board 101 is configured to perform the steps of the above-mentioned charging control method.

[0093] In an embodiment of the present disclosure, the vehicle includes a charging main board 101, a solar panel 102, and a battery 103.

[0094] The charging main board 101 may adopt PCBA (Printed Circuit Board + Assembly), that is, a PCB (Printed Circuit Board) empty board is loaded with components through SMT (Surface Mount Technology), and then through DIP (dual inline-pin package) plug-in production. A device for controlling the solar panel 102 is provided on the charging main board 101. The device can detect the charging current output by the solar panel 102, determine the charging scenario according to the charging current, and adjust the charging voltage threshold, and control the solar panel 102 to charge the battery 103 according to the adjusted charging voltage threshold.

[0095] The solar panel 102 may include a plurality of solar cells. The plurality of solar cells may be connected in series, or may be divided into multiple groups. The solar cells in each group are connected in series, and multiple groups of solar cells are connected in parallel. For example, the solar panel 102 includes 12 solar cells. The 12 solar cells may be connected in series, or 6 solar cells may be connected in series in each group, and two groups of solar cells are connected in parallel.

[0096] It can be understood that if a plurality of solar cells are connected in series, if one or more solar cells are blocked, the charging power of the entire solar panel will be reduced, and even the entire solar panel will stop power supply. However, if the solar cells are divided into multiple groups and connected in parallel, if the solar cells in one group are blocked, it will not affect the operation of the solar cells in other groups, and the solar panel can still supply power.

[0097] In practical applications, the input voltage range of the solar panel 102 may be between 0 - 9V, and the output charging power is 6W.

[0098] The battery 103 may be a lithium battery, and the output voltage range of the lithium battery may be between 3.6 - 4.2V.

[0099] In the above embodiments, the vehicle includes a charging main board, a solar panel, and a battery. The charging main board is respectively connected to the solar panel and the battery; the charging main board executes the steps of the above charging control method. By dynamically adjusting the charging voltage threshold in the embodiments of the present disclosure, the charging power of the solar panel is improved, thereby reducing the risk of the battery being undercharged.

[0100] In one embodiment, as Figure 5 shown, the charging main board 101 includes an anti-reverse diode 1011 and a charging chip 1012. The anti-reverse diode 1011 is connected to the solar panel 102, and the charging chip 1012 is respectively connected to the anti-reverse diode 1011 and the battery 103.

[0101] Based on the optoelectronic characteristics of monocrystalline silicon, the solar panel 103 acts as a source when there is light and charges the load battery; when there is no light, it acts as a load resistor and can draw current from the load battery. Therefore, to prevent reverse leakage of the load battery, an anti-reverse diode 1012 is provided on the charging main board 101, and the anti-reverse diode 1012 is respectively connected to the solar panel 102 and the charging chip 1012.

[0102] The charging chip 1012 can detect the charging current output by the solar panel 102, determine the charging scenario according to the charging current, and adjust the charging voltage threshold to control the solar panel 102 to charge the battery 103 according to the adjusted charging voltage threshold.

[0103] In some embodiments, the charging chip 1012 can also implement the function of DCDC (Direct Current - Direct Current) conversion and can also implement MPPT (Maximum PowerPoint Tracking). It should be noted that the functions that the charging chip 1012 can implement include but are not limited to the above description, and it can also implement other functions.

[0104] In the above embodiments, the charging main board includes an anti-reverse diode and a charging chip. The anti-reverse diode is connected to the solar panel, and the charging chip is respectively connected to the anti-reverse diode and the battery. In the embodiments of the present disclosure, an anti-reverse diode is provided on the charging main board 1, which can prevent reverse leakage of the load battery; and, without providing an anti-reverse diode on the solar panel, the cost of the solar panel can also be reduced.

[0105] In one embodiment, as Figure 6 shown, the vehicle includes a light load component 104 and a heavy load component 105; the light load component 104 is connected to the charging chip 1012; the heavy load component 105 is connected to the battery 103.

[0106] In the embodiments of the present disclosure, the vehicle includes a light-load component 104 and a heavy-load component 105. Among them, the extraction current of the light-load component 104 is less than that of the heavy-load component 105. For example, the extraction current of the light-load component 104 is 100 mA, and the extraction current of the heavy-load component 105 is 2000 mA.

[0107] A common connection method is that both the light-load component 104 and the heavy-load component 105 are connected to the charging chip 1012. However, this connection method is likely to cause the voltage output by the charging chip to the heavy-load component to exceed the battery voltage, that is, the problem of overvoltage occurs; and, because the extraction current of the heavy-load component is large and the discharge capacity of the charging chip is insufficient, it is easy to cause the voltage output to the heavy-load component to drop. To address these problems, the heavy-load component 105 is directly connected to the battery 103. In this way, the voltage output to the heavy-load component 105 is the battery voltage, which can reduce the overvoltage problem; and, the discharge capacity of the battery is higher than that of the charging chip. Therefore, it can also reduce the problem of voltage drop in the voltage output to the heavy-load component.

[0108] In the above embodiments, the vehicle includes a light-load component and a heavy-load component; the light-load component is connected to the charging chip 1012; the heavy-load component is connected to the battery. By directly connecting the heavy-load component to the battery in the embodiments of the present disclosure, the problems of overvoltage and voltage drop can be reduced, and the charging stability can be improved.

[0109] In one embodiment, as Figure 7 shown, the vehicle further includes a light-load switch 106, a heavy-load switch 107, and a watchdog 108. The light-load component 104 includes a microcontroller unit (MCU); the light-load component 104 is connected to the charging chip 1012 through the light-load switch 106; the heavy-load component 105 is connected to the battery 103 through the heavy-load switch 107; the watchdog 108 is connected to the light-load switch 106; the microcontroller unit is respectively connected to the watchdog 108 and the heavy-load switch 107.

[0110] In the embodiments of the present disclosure, the vehicle may further include a light-load switch 106, a heavy-load switch 107, and a watchdog 108. The light-load component 104 includes a microcontroller unit.

[0111] The light-load component 104 is connected to the charging chip 1012 through the light-load switch 106. The watchdog 108 is connected to the light-load switch 106, and the micro-control unit is connected to the watchdog 108. In practical applications, the micro-control unit can detect the working state of the light-load component 104 and control the watchdog 108 according to the working state of the light-load component 104. When the light-load component 104 is working normally, the micro-control unit normally controls the watchdog 108. When the light-load component 104 is abnormal or the micro-control unit is abnormal, the micro-control unit cannot normally control the watchdog 108, then the watchdog 108 will control the light-load switch 106 to turn off, thereby disconnecting the path between the charging chip 1012 and the light-load component 104 to protect the charging chip 1012. Subsequently, the watchdog 108 can control the light-load switch 106 to reset, thereby conducting the path between the charging chip 1012 and the light-load component 104.

[0112] The heavy-load component 105 is connected to the battery 103 through the heavy-load switch 107, and the micro-control unit is connected to the heavy-load switch 107. The micro-control unit can detect the working state of the heavy-load component 105 and control the heavy-load switch 107 to conduct or turn off according to the working state of the heavy-load component 105.

[0113] It should be noted that Figure 7 the connection relationship of the micro-control unit is not shown.

[0114] In the above embodiments, the vehicle further includes a light-load switch, a heavy-load switch and a watchdog. The light-load component includes a micro-control unit; the light-load component is connected to the charging chip through the light-load switch; the heavy-load component is connected to the battery through the heavy-load switch; the watchdog is connected to the light-load switch; the micro-control unit is respectively connected to the watchdog and the heavy-load switch. The embodiments of the present disclosure can protect the charging main board, the light-load component and the heavy-load component by controlling the connection relationships of the light-load component and the heavy-load component through the light-load switch, the heavy-load switch and the watchdog, thereby improving the service life of each component.
