[0034] After research, the inventor found that currently, there are several charging modes when using a charge pump to assist charging. Some charging modes support fast charging, but they cannot fully charge the battery. Some charging modes can fully charge the battery, but the charging speed is relatively poor. How to integrate several modes to achieve full charge and fast charging at the same time is the problem that this application will solve.

[0035] In order to solve the above problems, in an embodiment of the present application, the input voltage of the battery and the input current of the charge pump charging module are monitored. When the input voltage reaches a preset voltage value and the input current reaches a first current threshold, the charge pump charging module is enabled and turned off, and the charging mode of the charge pump charging module is switched to the first charging mode, wherein the charge pump charging module is configured with the second charging mode before switching. The embodiment of the present application realizes timely switching between the first charging mode and the second charging mode by monitoring the input voltage of the battery and the input current of the charge pump charging module, so that the charging process can be fully charged while achieving high efficiency.

[0036] The application content is further explained below through the description of embodiments in conjunction with the accompanying drawings.

[0037] like Figure 1 As shown, the method for dynamically switching charging modes provided in this embodiment specifically includes:

[0038] S100 , monitoring the input voltage of the battery and the input current of the charge pump charging module.

[0039] Specifically, the battery is a rechargeable battery that can be built into an electronic device, and the charge pump charging module can be configured in the functional module of the electronic device. The charge pump charging module is connected between the battery and the charging port of the electronic device, and the current input through the charging port flows into the battery after passing through the charge pump charging module to charge the battery, wherein the charge pump charging module is an inductorless DC-DC converter, which uses a capacitor as an energy storage element to perform voltage and current conversion. In one implementation, the input voltage of the battery is equal to the input voltage of the charge pump charging module, the input current of the battery is equal to the output current of the charge pump charging module, the input voltage of the charge pump charging module is equal to the output voltage of the adapter, and the input current of the charge pump charging module is equal to the output current of the adapter.

[0040] In one implementation of this embodiment, the charge pump charging module is configured with a first charging mode and a second charging module. In the first charging mode, the ratio of the input voltage of the charge pump charging module to the battery voltage is 2:2, and the ratio of the input current of the charge pump charging module to the battery current is 1:1; in the second charging mode, the ratio of the input voltage of the charge pump charging module to the battery voltage is 4:2, and the ratio of the input current of the charge pump charging module to the battery current is 1:2. For example, when the charge pump charging module is in the first charging mode and the battery voltage is 16V, the input power supply of the charge pump charging module is 16V, and correspondingly, the output voltage of the adapter is 16V; when the charge pump charging module is in the second charging mode and the battery voltage is 16V, the input power supply of the charge pump charging module is 32V, and correspondingly, the output voltage of the adapter is 32V.

[0041] In one implementation of this embodiment, when monitoring the input voltage of the battery and the input current of the charge pump charging module, the charge pump charging module is in the second charging mode, at which the input current is small, the line loss is low, the charging efficiency is higher and the heat generation is lower. However, the current of the PD protocol adapter can only be controlled to 1A at the minimum, and the current at the battery end is still 2A at this time, and the battery cannot reach a full state. Therefore, when the charge pump charging module is in the second charging mode, the input voltage of the battery and the input current of the charge pump charging module are monitored, so that when the input voltage of the battery and the input current of the charge pump charging module meet the preset requirements later, the charging mode of the charge pump charging module is automatically switched, that is, the second charging mode of the charge pump charging module is switched to the first charging mode. In the first charging mode, when the current value of the PD protocol adapter is 1A, the current at the battery end is 1A, so that the battery reaches a full state. In a typical implementation, the charge pump charging module can use a charge pump charging IC Ln8286, the first charging mode can be a bypass mode, and the second charging mode can be a switch mode.

[0042] S200. When the input voltage reaches a preset voltage value and the input current reaches a first current threshold, the charge pump charging module is enabled and turned off, and the charging mode of the charge pump charging module is switched to the first charging mode, wherein the charge pump charging module is configured to the second charging mode before switching.

[0043] Specifically, the preset voltage value and the first current threshold value can be pre-set and used as a limiting condition for limiting whether the charge pump charging module needs to switch the charging module, wherein the preset voltage value and the first current threshold value can be set according to actual needs. In an implementation of this embodiment, the preset voltage value can be set to 8.98V, and the first current threshold value can be set to the minimum output current of the adapter used to charge the battery, for example, 1A.

[0044] The charge pump charging module enable is responsible for controlling the input and output of the charge pump charging module signal. Turning off the charge pump charging module enable means that it is not responsible for controlling the input and output of the charge pump charging module signal, thereby blocking the normal operation of the charge pump charging module. In this step, in the process of switching the second charging mode to the first charging mode, since the input ratio of current and voltage between the battery and the charge pump charging module in the first charging mode and the second charging mode is different, and the charge pump charging module itself has a protection mechanism, when the first charging mode and the second charging mode are switched, the charge pump charging module will enter the standby mode in the working state and cannot continue to charge the battery end. Therefore, before switching, the normal operation of the charge pump charging module is blocked first.

[0045] In one implementation of this embodiment, in the first charging mode, the ratio of the input voltage of the charge pump charging module to the battery voltage is 2:2, and the ratio of the input current of the charge pump charging module to the battery input current is 1:1; in the second charging mode, the ratio of the input voltage of the charge pump charging module to the battery voltage is 4:2, and the ratio of the input current of the charge pump charging module to the battery input current is 1:2.

[0046] For example, in the first charging mode, the output voltage of the adapter can be set to 8.9V, the output current can be set to 1.75A, the input voltage of the charge pump charging module is equal to the output voltage of the adapter, which is 8.9V, the input current of the charge pump charging module is equal to the output current of the adapter, which is 1.75A, while the battery voltage is 8.9V and the battery input current is 1.75A; in the second charging mode, the output voltage of the adapter can be set to 8.9V, the output current can be set to 1.75A, the input voltage of the charge pump charging module is equal to the output voltage of the adapter, which is 8.9V, the input current of the charge pump charging module is equal to the output current of the adapter, which is 1.75A, while the battery voltage is 4.45V and the battery input current is 3.5A.

[0047] In an implementation of this embodiment, switching the charging mode of the charge pump charging module to the first charging mode specifically includes:

[0048] S201, controlling the adapter corresponding to the battery to adjust its own output voltage, and monitoring whether the charge pump charging module is in an over-power protection state.

[0049] Specifically, since the charge pump charging module is under the first charging module, the ratio of the battery voltage to the input voltage of the charge pump charging module is 1:1, and the input voltage of the charge pump charging module is equal to the output voltage of the adapter. Therefore, the ratio of the battery voltage to the input voltage of the charge pump charging module can be adjusted by controlling the output voltage of the adapter. In this embodiment, Figure 2As shown, when the battery in the second charging mode is just charged, a current value is input to the input current of the charge pump charging module, and then the value of the charge pump input current is adjusted by increasing the voltage of the adapter, thereby adjusting the value of the battery input current. A period of time is preset, and the input voltage of the charge pump charging module is increased every preset period of time, and the input voltage of the charge pump charging module is monitored in real time. In an implementation of this embodiment, the preset voltage value is 8.98V, and the first current threshold is 1A. By adjusting the output voltage of the adapter itself, the output voltage of the adjusted adapter is equal to the input voltage of the charge pump charging module, which is equal to the preset voltage value, and satisfies a condition that the charge pump charging module switches to the first charging mode. In this embodiment, the over-current protection refers to over-voltage protection. If the input voltage of the charge pump charging module is greater than the rated voltage, the charge pump charging module is in an over-voltage state at this time, and the input voltage of the charge pump charging module may cause damage to the battery. Therefore, it is necessary to monitor the input voltage of the charge pump charging module. When it is detected that the charge pump charging module is in an over-voltage state, a corresponding protection mechanism should be provided to prevent the battery from being damaged. Therefore, in the charge pump charging module of the present embodiment, there is a monitoring program for determining whether the charge pump charging module is in the over-power protection state. When the monitoring program determines that the charge pump charging module is in the over-power protection state, the state register of the charge pump charging module will display a state result mark, such as Figure 3 As shown, in the present embodiment, the status result of the status register is identified as vbus_ov, that is, when it is monitored that the status register has vbus_ov, it indicates that the charge pump charging module is in an over-power protection state. At this time, the charge pump charging module sends a control instruction to the adapter to control the adapter to adjust the output voltage; when it is monitored that the status register of the charge pump charging module does not have vbus_ov, that is, the charge pump charging module is not in an over-power protection state, then it is only necessary to monitor whether the battery voltage reaches the preset voltage value and whether the input current of the charge pump charging module is the first current threshold. When both are reached at the same time and the charge pump charging module is not in the over-power protection state, the second charging mode of the charge pump charging module is switched to the first charging mode.

[0050] In an implementation of this embodiment, the adjusted output voltage of the adapter is equal to the battery voltage of the battery.

[0051] Specifically, it can be known from the above that the purpose of adjusting the output voltage of the adapter mainly includes two aspects. One aspect is to prevent the input voltage of the charge pump charging module from overvoltage and causing damage to the battery. The other aspect is to convert the second charging mode of the charge pump charging module to the first charging mode of the charge pump charging module. In this step, the second charging mode of the charge pump charging module is converted to the first charging mode of the charge pump charging module. In the first charging mode, the ratio of the input voltage of the charge pump charging module to the battery voltage is 2:2. The input voltage of the charge pump charging module is equal to the output voltage of the adapter. Therefore, when the charging mode of the charge pump charging module is switched to the first charging mode, the output voltage of the adapter after adjustment should be equal to the battery voltage. The ratio is 2:2, that is, the output voltage of the adjusted adapter is equal to the battery voltage of the battery. It can be understood that when the second charging mode of the charge pump charging module is switched to the first charging mode, it is necessary to meet the battery voltage is a preset voltage value, the input current of the charge pump charging module is a first current threshold, and the charge pump charging module is not in an overvoltage protection state, so as to fully utilize the advantage of the high battery charging efficiency of the charge pump charging module in the second charging mode, and try to ensure that the charge pump charging module can no longer continue to charge in the second charging mode before switching the second charging mode of the charge pump charging module to the first charging mode to improve the charging efficiency as much as possible. Therefore, the output voltage of the adjusted adapter is equal to the preset voltage value of the battery voltage.

[0052] S202: When the charge pump charging module is not in an over-power protection state, switch the charging mode of the charge pump charging module to a first charging mode.

[0053] Specifically, when it is monitored that vbus_ov does not exist in the status register of the charge pump charging module, that is, the charge pump charging module is not in the overvoltage protection state, that is, the current input voltage of the charge pump charging module is less than or equal to the rated voltage, and will not cause damage to the battery. Therefore, there is no need to adjust the output voltage by controlling the adapter to control the input voltage of the charge pump charging module for overvoltage protection. The charge pump charging module can work normally, that is, the charge pump charging module is allowed to operate at any voltage not exceeding its own rated voltage, including switching the charging mode of the charge pump charging module to the first charging mode.

[0054] In an implementation of this embodiment, switching the charging mode of the charge pump charging module to the first charging mode further includes:

[0055] S203, when the charge pump charging module is in an over-current protection state, repeatedly controlling the adapter corresponding to the battery to adjust its own output voltage, and monitoring whether the charge pump charging module is in an over-current protection state, until the charge pump charging module is not in an over-current protection state.

[0056] Specifically, when the second charging mode of the charge pump charging module can no longer charge the battery and needs to be switched to the first charging mode, it is necessary to determine the output voltage of the adapter based on the battery voltage, and control the output voltage of the adapter so that the ratio of the input voltage of the charge pump charging module to the battery voltage conforms to the ratio of the input voltage of the charge pump charging module to the battery voltage in the first charging mode, so as to switch the charge pump charging module to the first charging mode. In the process of controlling the output voltage of the adapter, in order to prevent the charge pump charging module from being over-voltage and causing damage to the battery, it is necessary to monitor the status of the status register of the charge pump charging module in real time, that is, it is necessary to monitor in real time whether the status result identifier of the status register of the charge pump charging module contains vbus_ov. When the charge pump charging module is in an overvoltage protection state, it is necessary to reduce the input voltage of the charge pump charging module so that the charge pump input voltage is less than or equal to its own rated voltage, that is, to reduce the output voltage of the adapter to ensure that the charge pump charging module is not in an overvoltage protection state, thereby ensuring the normal operation of the battery.

[0057] In an implementation of this embodiment, after switching the charging mode of the charge pump charging module to the first charging mode, the method further includes:

[0058] S300 , controlling the charge pump charging module to be re-enabled, and setting the input current of the charge pump charging module to a second current threshold.

[0059] Specifically, when the battery voltage is a preset voltage value, the input voltage of the charge pump charging module is a first current threshold, and the charge pump charging module is not in an overvoltage protection state, the normal operation of the charge pump charging module is restored, and the second charging mode of the charge pump charging module is switched to the first charging mode. Before the second charging mode is converted to the first charging mode, the input current value of the charge pump charging module in the second charging mode is finally the first current threshold, that is, it reaches the value of the minimum input current of the charge pump charging module. At this time, the battery input current is equal to twice the first current threshold. For example, the first current threshold of the charge pump charging module in the second charging mode is 1A, and the battery current in the second charging mode is equal to 2A. When the battery in the second charging mode is charged to a certain amount of electricity, the battery input current at the battery end is too large at this time, so that the battery cannot continue to be charged to 100%. Therefore, the second charging mode of the charge pump charging module needs to be converted to the first charging mode. The ratio of the input current of the charge pump charging module to the battery input current in the first charging mode is 1:1. When the input current of the charge pump charging module remains unchanged, the battery input current value in the first charging mode is only half of the battery input current value in the second charging mode. Therefore, the input current of the battery is adjusted by adjusting the input current of the charge pump charging module, so that the input current of the battery in the first charging mode is less than twice the first current threshold, that is, the battery input current is made to be the second current threshold, so that the battery can continue to be charged. For example, the first current threshold of the charge pump charging module in the second charging mode is 1A, and the battery current in the second charging mode is equal to 2A. When the second charging module is switched to the first charging module, the input current of the charge pump charging module is adjusted to 1.45A. At this time, the input current of the battery is also 1.45A. In this state, it is sufficient to charge the battery to 100%.

[0060] In an implementation of this embodiment, the second current threshold is greater than the first current threshold.

[0061] Specifically, the first current threshold is the value of the minimum input current of the charge pump charging module, and the second current threshold is the value of the input current for normal operation of the charge pump charging module in the first charging mode. When the charge pump charging module is converted from the second charging mode to the first charging mode, the first current threshold of the charge pump charging module is ultimately equal to the battery input current, the input voltage of the charge pump charging module is equal to the battery input voltage, and the output voltage of the charge pump charging module itself does not form a voltage difference with the battery. Therefore, it is necessary to make the input current of the charge pump charging module greater than the battery current, that is, the second current threshold is greater than the first current threshold, so as to form a voltage difference, and then form a charging current.

[0062] The present invention also provides a device for dynamically switching charging modes, such as Figure 4As shown, it includes:
