Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The flow diagrams depicted in the figures are exemplary only and not necessarily all steps are included. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations. In addition, all of the following terms "first," "second," are used for distinguishing purposes only and should not be taken as a limitation of the present disclosure.

The direct charging disclosed by the disclosure means that the output of the adapter is directly connected with the battery of the charged terminal equipment, power conversion is not needed in the middle, and the charging efficiency is high and the heating is small.

The terminal equipment cannot acquire accurate adapter state information through protocol communication, a current detection circuit needs to be added on an adapter output loop, and whether the adapter is pulled out or not is judged through the current flowing into the terminal equipment by the adapter.

On the one hand, adding the current detection circuit increases the design cost and occupies the PCB space. On the other hand, in PD (protocol applied to Power control under USB organization), because there is a communication timeout, a situation may occur in which the adapter has been pulled out but a charging icon is still displayed on the terminal interface, which affects the user experience.

In view of this, a new adapter unplugging detection scheme is needed.

Fig. 1 shows a schematic diagram of a system architecture of an adapter unplugging scheme of an embodiment of the present disclosure.

Referring to fig. 1, a terminal device 11 is connected to an adapter 12. The terminal device 11 may communicate data with the adapter 12 via a common protocol. The terminal device 11 may be any device equipped with a secondary battery power supply function, including, but not limited to, a smart phone, a smart wearable device, a tablet computer, a portable computer, a desktop computer, and the like. In addition, adapter 12 may also be referred to as a charger.

The terminal device 11 comprises, in addition to a battery (not shown), at least a processor 110, a power management module 111, an ADC module 112, a protocol module 113.

In implementing the adapter pull-out detection scheme of the embodiment of the present disclosure, first, in a case where the battery of the terminal device 11 is not charged completely, the power management module 111 may acquire a current value flowing into the battery and transmit the current value to the processor 110.

Next, when the processor 110 determines that the time period of one discharge of the battery is longer than the first predetermined time based on the obtained current value, on the one hand, the ADC module 112 may read the current input voltage of the terminal device 11, and record the current input voltage as the first input voltage; on the other hand, the protocol module 113 may implement data transmission between each other based on a protocol between the terminal device 11 and the adapter 12. Specifically, protocol module 113 can read the current output voltage of adapter 12, denoted as the first output voltage.

Subsequently, the processor 110 may send a control command to control the charging process to stop, i.e., disable charge. And controls the boost of the output voltage of adapter 12 from the first output voltage to the second output voltage.

After the output voltage of the adapter 12 rises to the second output voltage, the current input voltage of the terminal device 11 is read by the ADC module 112 by a Delay (Delay) for a second predetermined time, denoted as the second input voltage.

After knowing the first input voltage and the second input voltage of the terminal device 11, the processor 110 may compare the first input voltage with the second input voltage and determine whether the adapter 12 is pulled out from the power supply based on the comparison result.

Specifically, in the case that the first input voltage is equal to or greater than the second input voltage, it is determined that the adapter 12 has been pulled out; in the event that the first input voltage is less than the second input voltage, it is determined that the adapter 12 is not unplugged.

In addition, in the case where the adapter 12 is not pulled out, the adapter 12 may be continuously controlled to charge the terminal device 11.

Fig. 3 schematically illustrates a flowchart of an adapter pull-out detection method of an exemplary embodiment of the present disclosure. Referring to fig. 3, the adapter pull-out detection method may include the steps of:

s32, when the battery of the terminal equipment is not charged, and the primary discharging time of the battery is longer than the first preset time, the first input voltage of the terminal equipment and the first output voltage of the adapter are read.

The battery charge completion according to the embodiment of the present disclosure refers to a state in which the battery is fully charged. For example, whether the battery is charged or not may be determined by parameters such as current and voltage of the battery, and the present disclosure does not limit a determination manner of whether the battery is charged or not.

For determining whether the battery is in a discharged state or a charged state, the current value flowing into the battery may be used for determination in the embodiments of the present disclosure.

Specifically, the terminal device may read a current value flowing into the battery through the equipped power management module, and determine whether the battery is in a discharged state according to the current value. When the current value is greater than 0, the battery can be determined to be in a charging state; when the current value is less than 0, it can be determined that the battery is in a discharged state. It should be understood that the terminal device may determine the charge and discharge states of the battery in real time.

The one-time discharge period described in the embodiments of the present disclosure refers to a period in which the battery is in a discharge state only, and in this period, there is no case in which the battery is in a charge state.

In some embodiments of the present disclosure, first, upon detecting that the battery is switched from a charged state to a discharged state, counting is started. Next, in the process of the continuous detection by the terminal device, if the battery is detected to be in a discharged state, the count is incremented by 1. When the counted value is equal to the predetermined threshold value, it may be determined that a time period of one discharge of the battery is longer than the first predetermined time. Wherein the disclosure does not limit 〧 the specific values of the predetermined threshold and the first predetermined time For example, the predetermined threshold may be 2, 3, 4, 5, or the like.

It should be noted that in the counting process, when the battery is detected to be switched from a discharging state to a charging state, the count is cleared.

In other embodiments of the present disclosure, first, upon detecting a battery switch from a charged state to a discharged state, a timer is started. Next, if the batteries are in a discharge state within a first predetermined time after starting the timer, it is determined that a time of one discharge of the batteries is longer than the first predetermined time.

When the primary discharge time of the battery is longer than the first preset time, the current input voltage of the terminal equipment can be read and recorded as the first input voltage. The current output voltage of the adapter is read and recorded as a first output voltage.

It will be appreciated that, in theory, the first input voltage of the terminal device is equal to the first output voltage of the adapter. However, the first output voltage of the adapter is typically slightly greater than the first input voltage of the terminal device due to the unavoidable voltage drop over the connection lines.

Specifically, the first input voltage of the terminal device may be read by an ADC module provided with the terminal device. And reads the first output voltage of the adapter based on the protocol module.

S34, controlling the charging process to stop, and increasing the output voltage of the adapter from the first output voltage to the second output voltage.

After reading the first input voltage of the terminal device and the first output voltage of the adapter, the terminal device may control the charging process to stop, i.e. Disable charging. Specifically, the processor of the terminal device may interact with the charging chip based on the I2C protocol, and implement Disable charging by sending a control command to the charging chip.

After stopping the control charging process, the terminal device may control to increase the output voltage of the adapter from the first output voltage to the second output voltage.

Specifically, the first output voltage may be added to a predetermined voltage to obtain a second output voltage, and the output voltage of the adapter may be adjusted to the second output voltage.

For the determination of the predetermined voltage, two aspects may be combined to consider, on the one hand, the input voltage of the terminal device is obtained through conversion by the ADC module, and since there may be a certain error in the conversion process, the conversion may be smaller than the actual voltage, and this error is recorded as the first error in the disclosure. On the other hand, the output voltage of the adapter is also obtained through conversion of the ADC module, and the error is recorded as a second error. Wherein the first error and the second error are both within 1%.

The predetermined voltage is determined based on the first error and the second error. In order to ensure that the voltage after adjustment (second output voltage) is necessarily greater than the voltage before adjustment (first output voltage), a certain margin may be added in consideration of the above-described error.

For example, the predetermined voltage may be configured to be 0.5V.

In addition, the predetermined voltage may be a fixed voltage determined empirically by a developer, and the value of the predetermined voltage is not limited in the present disclosure.

S36, delaying for a second preset time, and reading a second input voltage of the terminal equipment.

After the output voltage of the adapter is raised to the second output voltage, it may be delayed by a second predetermined time, for example, 300ms, and the current input voltage of the terminal device is read again and noted as the second input voltage. In particular, the second input voltage of the terminal device may be read by an ADC module provided with the terminal device.

It will be appreciated that if the adapter has been unplugged, the second input voltage acquired after the delay will not be higher than the first input voltage due to the reverse recharging of the battery.

S38, comparing the first input voltage with the second input voltage, and determining that the adapter is pulled out under the condition that the first input voltage is larger than or equal to the second input voltage.

And if the interface still has the charging icon under the condition that the adapter is pulled out, controlling the charging icon to disappear. For example, the charge icon is disappeared by changing the charge flag bit.

In addition, it is understood that in the event that the first input voltage is less than the second input voltage, it may be determined that the adapter is not unplugged.

And under the condition that the adapter is not pulled out, the terminal equipment can control the charging process to start, namely the Enable charging. Specifically, the processor of the terminal device may send a charging start command to the charging chip based on the I2C protocol to implement Enable charging.

In addition, the terminal device may reduce the output voltage of the adapter from the second input voltage to the first output voltage. I.e., returning to the original charging output voltage, and continuing the charging.

Fig. 4 schematically shows a flowchart of the entire process of adapter pull-out detection of an embodiment of the present disclosure.

In step S402, the terminal device performs PPS direct charging, and counts count=0.

In step S404, the terminal device determines whether the charging is completed, that is, whether the battery is full. If the charging is completed, the flow ends. If the charging is not completed, step S406 is performed.

In step S406, the terminal device determines whether the current I flowing into the battery is greater than 0. If I is greater than 0, indicating that the battery is in a charged state, returning to step S402; if I is less than 0, it indicates that the battery is in a discharged state, and step S408 is performed. It can be understood that in the case where the terminal device is turned on, there is almost no case where i=0.

In step S408, count+1 is counted.

In step S410, it is determined whether the Count is greater than 2. If greater than 2, then step S412 is performed; if not greater than 2, the process returns to step S402.

In step S412, the first input voltage Vbus1 of the terminal device and the first output voltage Vcv1 of the adapter are read.

In step S414, the terminal device controls the charging process to stop, and raises the output voltage of the adapter to the second output voltage Vcv2.

In step S416, after a delay of 300ms, the second input voltage Vbus2 of the terminal device is read.

In step S418, the terminal device determines that the adapter has been pulled out when the magnitude relation between the second input voltage Vbus2 and the first input voltage Vbus1 is determined and the second input voltage Vbus2 is less than or equal to the first input voltage Vbus 1; if the second input voltage Vbus2 is greater than the first input voltage Vbus1, it is determined that the adapter is not pulled out, and step S420 is performed.

In step S420, the terminal device controls the charging process to start.

In step S422, the terminal device may control to decrease the output voltage of the adapter to the first output voltage Vcv1, and return to step S402 to continue charging.

According to the adapter explosion detection scheme based on the embodiment of the disclosure, on one hand, the detection of whether the adapter is pulled out or not can be realized without modifying hardware, so that the cost and the PCB space are saved, and meanwhile, the scheme is simple to implement, has strong universality and is suitable for various types of terminal equipment; on the other hand, in view of the scheme of the present disclosure, whether the adapter is pulled out or not can be detected in time, and on the basis of the result, the display of the charging icon can be controlled in time, so that the problem that the charging icon still appears on the interface when the adapter is pulled out is solved, and the user experience is improved; on the other hand, under the condition that the continuous discharge of the battery is determined, the method still combines the adjustment of the output voltage of the adapter to further judge whether the adapter is pulled out or not, and the method does not directly depend on the discharge to judge, so that the possible condition that the battery is charged while being used and the discharge is possibly caused is considered, the misjudgment is avoided, and the detection accuracy is high.

It should be noted that although the steps of the methods in the present disclosure are depicted in the accompanying drawings in a particular order, this does not require or imply that the steps must be performed in that particular order, or that all illustrated steps be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc.
