Description

Technical Field

[0002] At present, the use of mobile electronic devices is very common in people's production and life. How to charge mobile electronic devices is also an important issue.

[0003] In the prior art, mobile electronic devices use a linear charging method. The mobile electronic device, as the charged device, is connected to the charging device through a charging connection device, and the charging device charges the charged device through the charging connection device. When the linear charging method is used, the maximum charging current is limited by the heat dissipation power that the charging connection device can withstand. Therefore, the charging current is generally small, and after entering the constant current charging stage, the charging current is only set to a fixed current, resulting in a long charging time and low charging efficiency.

[0004] Meanwhile, some charging devices are designed for constant power output. When the charging device charges the charged device through the charging connection device, the heat dissipation power on the charging connection device causes the voltage output by the charging device to be different, further resulting in longer charging time and lower charging efficiency.

[0009] Optionally, while maintaining the real-time charging current unchanged, the method further includes: when the real-time heat dissipation power decreases to a preset first power threshold, increasing the real-time charging current.

[0010] Optionally, when the real-time heat dissipation power decreases to a preset first power threshold, the real-time charging current is increased, and it also includes: when the real-time heat dissipation power increases to the fourth power threshold, stopping increasing the real-time charging current, and maintaining the real-time charging current unchanged until the real-time heat dissipation power decreases to the first power threshold again.

[0011] Optionally, increasing the real-time charging current when the charging device charges the charged device also includes: obtaining a first real-time voltage, wherein the first real-time voltage is the output voltage of the charging device; and reducing the real-time charging current when the voltage value of the first real-time voltage does not decrease.

[0012] Optionally, when the voltage value of the first real-time voltage does not decrease, reducing the real-time charging current also includes: when the real-time heat dissipation power is equal to or less than the fourth power threshold, stopping reducing the real-time charging current and maintaining the real-time charging current unchanged.

[0013] In a second aspect, an embodiment of the present application provides a charging control device, comprising: a current increasing module, used to increase the real-time charging current of the charging device when the charging process of the charging device for the charged device is started; a power acquisition module, used to acquire real-time heat dissipation power, wherein the heat dissipation power is the real-time power lost by the charging connection device connecting the charging device and the charged device when the charging device charges the charged device; a current reducing module, used to reduce the real-time charging current when the real-time heat dissipation power increases to a maximum heat dissipation power during the process of increasing the real-time charging current, wherein the maximum heat dissipation power is the maximum value of the heat dissipation power that the charging connection device can withstand; a current maintaining module, used to stop reducing the real-time charging current and maintain the real-time charging current unchanged when the real-time heat dissipation power is reduced to a preset fourth power threshold during the process of reducing the real-time charging current.

[0017] In the process of charging the charged device by the charging device, the method dynamically adjusts the real-time charging current according to the real-time heat dissipation power. When the real-time heat dissipation power has not increased to the maximum heat dissipation power of the charging connection device, the real-time charging current is continuously increased. The larger the charging current, the shorter the charging time taken to fully charge the charged device, and thus the higher the charging efficiency. When the real-time heat dissipation power increases to the maximum heat dissipation power, the real-time charging current is immediately reduced to avoid damage to the charging connection device. In the process of reducing the real-time charging current, when the real-time heat dissipation power is reduced to the preset fourth power threshold, the real-time charging current is no longer reduced, but the real-time charging current is maintained unchanged. By presetting the specific value of the fourth power threshold, the real-time charging current can be maintained at a larger value, further improving the charging efficiency. The process of dynamic adjustment of the real-time charging current of the method avoids charging with a fixed current and the long charging time caused by the constant power output of the charging device, shortens the charging time, and improves the charging efficiency.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The charging control method provided in the embodiment of the present application is applied to the process in which the charging device charges the charged device. Figure 1 As shown, the charging device 101 is a device for providing electric energy, which can be any one of a charger, a power bank, and other types of electric energy providing devices. When the charging device 101 is a device such as a charger that cannot provide electric energy by itself, the charging device 101 can be connected to other energy supply equipment. The charging device 101 is connected to the charged device 103 through a charging connection device 102. The charging connection device 102 is any connection device that provides an electric energy transmission path, such as a connection circuit. The charged device 103 is a device that needs to be supplemented with electric energy, for example, a built-in battery of a mobile electronic device such as a smart phone, a tablet computer, a laptop computer, or an independent battery that can be charged, or any other device that needs electric energy.

[0028] The charging control method provided in the embodiment of the present application is implemented in the charged device 103. Specifically, the charged device 103 includes a control center capable of implementing the method. For example, when the charged device 103 is a smart phone, the method is implemented in the power management chip of the smart phone.

[0029] In one embodiment, if Figure 2 As shown, a charging control method, the specific process steps of implementation are as follows:

[0030] Step 201: when the charging process of the charging device for the charged device is started, the real-time charging current of the charging device when charging the charged device is increased.

[0031] In this embodiment, when the charging device starts to charge the charged device, for example, when the mobile phone charger is inserted into the charging port of the mobile phone through the connecting line and starts to charge the mobile phone, the real-time charging current will increase from a preset current initial value. The preset current initial value can be set according to actual conditions and needs. For example, the current initial value is set to 0 amperes (ampere, abbreviated as A), or the current initial value is set to 0.5A.

[0032] When the charging process starts, the real-time charging current starts to increase continuously from the initial current value, and the rate of increase can be set according to actual conditions, experimental data and / or empirical data. The scope of protection of this application is not limited to the specific value of the setting method of the increase rate.

[0033] Step 202 : acquiring real-time heat dissipation power, wherein the heat dissipation power is the real-time power consumed by a charging connection device connecting the charging device and the charged device when the charging device charges the charged device.

[0034] In this embodiment, due to the continuous change of the real-time charging current flowing through the charging connection device and the advancement of the charging process, the voltage difference on the charging connection device will also change. Due to the changes in the real-time charging current and the voltage difference, the real-time heat dissipation power of the charging connection device will also change.

[0035] In one embodiment, the real-time heat dissipation power is obtained, and the specific implementation process is as follows: when the charging device charges the charged device, the real-time charging current, the first real-time voltage and the second real-time voltage are obtained; according to the real-time charging current, the first real-time voltage and the second real-time voltage, the real-time heat dissipation power is calculated. Among them, the first real-time voltage is the output voltage of the charging device; the second real-time voltage is the input voltage of the charged device.

[0036] In this embodiment, Figure 1 It can be seen that the output voltage of the charging device is the input voltage of the charging connection device, that is, the first real-time voltage is equal to the input voltage of the charging connection device; similarly, the input voltage of the charged device is the output voltage of the charging connection device, that is, the second real-time voltage is equal to the output voltage of the charging connection device.

[0037] In a specific embodiment, the real-time heat dissipation power is calculated according to the real-time charging current, the first real-time voltage, and the second real-time voltage. The calculation can be implemented according to a specific formula. Specifically, the real-time heat dissipation power is calculated according to the following formula:

[0038] Real-time heat dissipation power=(first real-time voltage−second real-time voltage)×real-time charging current.

[0039] In this embodiment, the voltage drop on the charging connection device is obtained by subtracting the second real-time voltage from the first real-time voltage, and the voltage drop is multiplied by the real-time charging current flowing through the charging connection device to obtain the real-time heat dissipation power of the charging connection device.

[0040] In this embodiment, the first real-time voltage and the second real-time voltage can be obtained by a simple voltage acquisition device, and the real-time charging current can be obtained by a simple current acquisition device. The above calculation formula is simple in logic, and the real-time heat dissipation power of the charging connection device can be conveniently obtained through the above calculation formula, thereby improving the convenience of real-time charging current adjustment, avoiding the large delay in the obtained real-time heat dissipation power due to the complex processing process, and affecting the sensitivity of real-time charging current adjustment.

[0041] Step 203 , when the real-time heat dissipation power increases to the maximum heat dissipation power during the process of increasing the real-time charging current, the real-time charging current is reduced, wherein the maximum heat dissipation power is the maximum value of the heat dissipation power that the charging connection device can withstand.

[0042] In this embodiment, the real-time heat dissipation power of the charging connection device is the most important limiting factor for the charging current not to be too large. In the process of increasing the real-time charging current, it is necessary to ensure that the real-time heat dissipation power does not exceed the maximum heat dissipation power of the charging connection device. When the real-time heat dissipation power reaches the maximum heat dissipation power, the real-time charging current is immediately reduced to avoid damage to the charging connection device.

[0043] Step 204, during the process of reducing the real-time charging current, when the real-time heat dissipation power is reduced to a preset fourth power threshold, stop reducing the real-time charging current and maintain the real-time charging current unchanged, wherein the fourth power threshold is less than the maximum heat dissipation power.

[0044] In this embodiment, in order to ensure charging efficiency, the real-time charging current cannot be reduced continuously, so a fourth power threshold is set in advance. When the real-time heat dissipation power is reduced to the preset fourth power threshold, the real-time charging current stops being reduced and is maintained unchanged.

[0045] The specific value of the fourth power threshold can be set according to actual conditions, experimental data and / or empirical data, as long as the real-time charging current is relatively large under the premise that the real-time heat dissipation power is not greater than the maximum heat dissipation power. In this way, device damage can be avoided and higher charging efficiency can be achieved.

[0046] In one embodiment, when the real-time charging current remains unchanged, the input voltage of the charged device, i.e., the second real-time voltage, will continue to increase due to the continuous increase in charging time, and when the output voltage of the charging device, i.e., the first real-time voltage, remains unchanged, the real-time heat dissipation power will continue to decrease. During the charging process, the real-time heat dissipation power is continuously monitored, and when the real-time charging current is maintained unchanged and the real-time heat dissipation power decreases to a preset first power threshold, the real-time charging current is increased.

[0047] In this embodiment, the first power threshold is less than the fourth power threshold, and the first power threshold is pre-set according to actual conditions, experimental data and / or empirical data, and the protection scope of this application is not limited to the setting method and specific value of the first power threshold. When the real-time heat dissipation power is reduced to the first power threshold, the real-time charging current is increased again to further shorten the charging time and improve the charging efficiency.

[0048] In one embodiment, when the real-time heat dissipation power decreases to a preset first power threshold, the real-time charging current is increased. When the real-time heat dissipation power increases to a fourth power threshold, the real-time charging current is stopped from being increased, and the real-time charging current is maintained unchanged until the real-time heat dissipation power decreases to the first power threshold again.

[0049] In this embodiment, the real-time heat dissipation power is compared with the first power threshold and the fourth power threshold respectively, and the real-time charging current is cyclically adjusted. When the real-time heat dissipation power decreases to the first power threshold, the real-time charging current begins to increase to speed up the charging speed. When the real-time heat dissipation power increases to the fourth power threshold during the process of increasing the real-time charging current, the real-time charging current is stopped from being increased and maintained unchanged to avoid excessive real-time heat dissipation power, which may cause damage to the device. At the same time, the real-time charging current is maintained at a larger value to ensure higher charging efficiency.

[0050] In one embodiment, when the charging device outputs constant power, the first real-time voltage will be reduced when the real-time charging current is increased. At this time, the voltage difference on the charging connection becomes smaller, and the real-time charging current can continue to be increased, while monitoring the real-time heat dissipation power not to exceed the maximum heat dissipation power. However, when the charging device does not output constant power, when the real-time charging current increases, the first real-time voltage does not decrease, which may cause the real-time heat dissipation power to increase sharply. Therefore, while increasing the real-time charging current when the charging device is charging the charged device, the first real-time voltage is obtained, wherein the first real-time voltage is the output voltage of the charging device; when the voltage value of the first real-time voltage does not decrease, the real-time charging current is reduced. In this way, it is possible to avoid the sharp increase in real-time heat dissipation power and damage to the device.

[0051] In one embodiment, when the voltage value of the first real-time voltage does not decrease, during the process of reducing the real-time charging current, when the real-time heat dissipation power is equal to or less than the fourth power threshold, the real-time charging current is stopped from being reduced and the real-time charging current is maintained unchanged.

[0052] In this embodiment, when it is determined that the voltage value of the first real-time voltage is decreasing and the real-time charging current is reduced, in order to ensure the charging efficiency, the fourth power threshold is used to determine whether to stop reducing the real-time charging current, so as to avoid the situation where the charging time is prolonged due to excessive reduction in the real-time charging current.

[0053] In a specific embodiment, Figure 3 As shown, the charging device starts the charging process for the charged device, and monitors and obtains the real-time heat dissipation power in real time during the entire charging process. The specific implementation process of the charging control method is as follows:

[0054] Step 301, the charging process of the charging device for the charged device is started;

[0055] Step 302, increasing the real-time charging current;

[0056] Step 303, determining whether the first real-time voltage decreases, if so, executing step 304, if not, executing step 305;

[0057] Step 304, determining whether the real-time heat dissipation power is greater than the maximum heat dissipation power, if so, executing step 305, if not, executing step 302;

[0058] Step 305, reducing the real-time charging current;

[0059] Step 306, determining whether the real-time heat dissipation power is equal to or less than a fourth power threshold, if so, executing step 307, if not, executing step 305;

[0060] Step 307, maintaining the real-time charging current unchanged;

[0061] Step 308, determining whether the real-time heat dissipation power is equal to or less than the first power threshold, if so, executing step 309, if not, executing step 307;

[0062] Step 309 , increase the real-time charging current and execute step 306 .

[0063] In the above process, during the entire charging process, when the charged device is fully charged, for example, when the second real-time voltage reaches a voltage value representing the charging power, charging is stopped immediately.

[0064] In one embodiment, during the charging process, there is a hysteresis effect in the process of obtaining the real-time heat dissipation power, and in the process of controlling the current to increase or decrease. Specifically, in the process of increasing the real-time charging current, since obtaining the real-time heat dissipation power requires a processing process, the real-time charging current will continue to increase during this process, and the real-time heat dissipation power obtained will be greater than the actual real-time heat dissipation power. Therefore, a corresponding second power threshold is set for the first power threshold, and the second power threshold is greater than the first power threshold and less than the fourth power threshold. The first power threshold is used to avoid the hysteresis effect. Similarly, in the process of the real-time charging current being unchanged or decreasing, since obtaining the real-time heat dissipation power requires a processing process, the second real-time voltage will continue to increase during this process, and the real-time heat dissipation power obtained will be less than the actual real-time heat dissipation power. Therefore, a corresponding third power threshold is set for the fourth power threshold, and the third power threshold is greater than the fourth power threshold. The third power threshold is used to avoid the hysteresis effect.

[0065] In this embodiment, when the real-time charging current is increased, when the real-time heat dissipation power increases to the maximum heat dissipation power and the real-time charging current is reduced, if the real-time heat dissipation power is greater than the third power threshold, the real-time charging current continues to be reduced; when the real-time heat dissipation power is reduced to the fourth power threshold, the real-time charging current is stopped from being reduced and the real-time charging current is maintained unchanged.

[0066] In this embodiment, when the real-time charging current is stopped from being reduced and the real-time charging current is maintained unchanged, if the real-time heat dissipation power is reduced to the first power threshold, the real-time charging current is increased; during the process of increasing the real-time charging current, if the real-time heat dissipation power increases to the second power threshold, the real-time charging current is stopped from being increased, and then it is determined whether the real-time heat dissipation power increases to the third power threshold due to the hysteresis effect, and if so, the real-time charging current is reduced. Entering the process of cyclically adjusting the real-time charging current through the first power threshold, the second power threshold, the third power threshold and the fourth power threshold.

[0067] In a specific embodiment, V1 represents the first real-time voltage, V2 represents the second real-time current, I represents the real-time charging current, and P represents the real-time heat dissipation power. The calculation formula of P is as follows:

[0068] P = (V1-V2) × I.

[0069] The preset power thresholds include maximum heat dissipation power, a first power threshold, a second power threshold, a third power threshold and a fourth power threshold, Pmax represents the maximum heat dissipation power, P1 represents the first power threshold, P2 represents the second power threshold, P3 represents the third power threshold, and P4 represents the fourth power threshold.

[0070] In this embodiment, V1 and V2 are detected in real time by a voltage monitoring device, I is monitored in real time by a current monitoring device, and P is obtained in real time through V1, V2, and I. Based on the real-time obtained V1, V2, I, and P, as Figure 4 shown, the detailed process of implementing the charging control method is as follows:

[0071] Step 401, the charging device starts the charging process for the device to be charged;

[0072] Step 402, increase the real-time charging current I;

[0073] Step 403, determine whether V1 becomes smaller. If so, execute Step 404; if not, execute Step 405;

[0074] Step 404, determine whether P > Pmax holds. If so, execute Step 405; if not, execute Step 402;

[0075] Step 405, decrease the real-time charging current I;

[0076] Step 406, determine whether P > P3 holds. If so, execute Step 407; if not, execute Step 410;

[0077] Step 407, reduce the real-time charging current I;

[0078] Step 408, determine whether P < P4 holds. If so, execute Step 409; if not, execute Step 407;

[0079] Step 409, keep the real-time charging current I unchanged and execute Step 406;

[0080] Step 410, determine whether P < P1 holds. If so, execute Step 411; if not, execute Step 409;

[0081] Step 411, increase the real-time charging current I;

[0082] Step 412, determine whether P > P2 holds. If so, execute Step 409; if not, execute Step 411.

[0083] During Figure 4 the process shown, the voltage monitoring device monitors V2 in real time. When V2 reaches the voltage required by the device to be charged, the charging is stopped, that is, the real-time charging current is reduced to zero.

[0084] In a specific embodiment, the first power threshold, the second power threshold, the third power threshold and the fourth power threshold are determined according to the minimum rated power of the rated powers corresponding to the charging device, the charged device and the charging connection device. Specifically, the first power constant, the second power constant, the third power constant and the fourth power constant are set according to actual conditions and needs, wherein the first power constant is greater than the second power constant, and the second power constant is greater than the third power constant, and the third power constant is greater than the fourth power constant, that is:

[0085] The first power constant>the second power constant>the fourth power constant>the third power constant.

[0086] Based on the above, the first power threshold, the second power threshold, the third power threshold and the fourth power threshold are obtained respectively by the following formulas:

[0087] First power threshold = minimum rated power - first power constant;

[0088] The second power threshold = minimum rated power - second power constant;

[0089] The third power threshold = minimum rated power - the third power constant;

[0090] The fourth power threshold=minimum rated power-fourth power constant.

[0091] In this embodiment, by setting the first power constant, the second power constant, the third power constant and the fourth power constant, the first power threshold, the second power threshold, the third power threshold and the fourth power threshold are respectively reserved for the margin of the minimum rated power, and at the same time, the second power constant is the hysteresis threshold of the first power constant, and the fourth power constant is the hysteresis threshold of the third power constant. Thus, confusion in real-time charging current adjustment or damage to the device due to the hysteresis effect can be avoided.

[0092] The charging control method provided in the embodiment of the present application continuously increases the real-time charging current when the charging device starts the charging process for the charged device. When the real-time charging current increases, the real-time heat dissipation power consumed by the charging connection device flowing through the real-time charging current also increases continuously. When the real-time heat dissipation power increases to the maximum heat dissipation power, the real-time charging current begins to decrease. When the real-time charging current decreases, the real-time heat dissipation power consumed by the charging connection device flowing through the real-time charging current also decreases continuously. When the real-time heat dissipation power decreases to the preset fourth power threshold, the real-time charging current stops being reduced and the real-time charging current is maintained unchanged.

[0093] In the process of charging the charged device by the charging device, the method dynamically adjusts the real-time charging current according to the real-time heat dissipation power. When the real-time heat dissipation power has not increased to the maximum heat dissipation power of the charging connection device, the real-time charging current is continuously increased. The larger the charging current, the shorter the charging time taken to fully charge the charged device, and thus the higher the charging efficiency. When the real-time heat dissipation power increases to the maximum heat dissipation power, the real-time charging current is immediately reduced to avoid damage to the charging connection device. In the process of reducing the real-time charging current, when the real-time heat dissipation power is reduced to the preset fourth power threshold, the real-time charging current is no longer reduced, but the real-time charging current is maintained unchanged. By presetting the specific value of the fourth power threshold, the real-time charging current can be maintained at a larger value, further improving the charging efficiency. The process of dynamic adjustment of the real-time charging current of the method avoids charging with a fixed current and the long charging time caused by the constant power output of the charging device, shortens the charging time, and improves the charging efficiency.

[0094] Based on the same concept, a charging connection device is provided in the embodiment of the present application. The specific implementation of the device can refer to the description of the method embodiment part, and the repeated parts will not be repeated. Figure 5 As shown, the device mainly includes:

[0095] The current increasing module 501 is used to increase the real-time charging current of the charging device when the charging process of the charging device for the charged device is started;

[0096] The power acquisition module 502 is used to acquire real-time heat dissipation power, wherein the heat dissipation power is the real-time power consumed by the charging connection device connecting the charging device and the charged device when the charging device charges the charged device;

[0097] The current reducing module 503 is used to reduce the real-time charging current when the real-time heat dissipation power increases to the maximum heat dissipation power during the process of increasing the real-time charging current, wherein the maximum heat dissipation power is the maximum value of the heat dissipation power that the charging connection device can withstand;
