s200, when the current pulse signal is detected, converting the current pulse signal generated by the instant jitter of the mobile terminal into a corresponding voltage signal;
and S300, performing voltage stabilization processing or level conversion processing on the voltage signal.
The above steps are described in detail with reference to specific examples.
Specifically, the mobile terminal of the present invention may be a mobile terminal such as a mobile phone and a tablet computer. In practical application, a current pulse detection module is arranged, and the current pulse detection module detects a current pulse signal generated by shaking of the mobile terminal during charging. When the current pulse detection module detects a current pulse signal generated by shaking of the mobile terminal during charging, the current pulse detection module outputs a pulse driving signal to the current-voltage conversion module, and the current-voltage conversion module converts the current pulse signal generated by instant shaking of the mobile terminal into a voltage signal.
There are two processing manners, one is to perform level conversion processing on the voltage signal and convert the voltage signal into a corresponding low level signal.
Further, the step S300 includes:

Specifically, the voltage signal is a high-level signal, the current pulse signal is a high-level signal which is converted correspondingly, the high-level voltage signal is converted into a low-level signal through the level conversion module, and the low-level signal does not damage the devices of the charging system.
In practical application, when a large-current pulse signal is generated on the VBUS of the mobile terminal, the current pulse signal is detected by the current pulse detection module. And if the current pulse signal is converted into a high-level voltage signal through the current-voltage conversion module and the high-level voltage signal is converted into a low-level signal through the level conversion module, interrupting the charging current to charge the mobile terminal through the VBUS power line.
Another processing method is to perform voltage stabilization on the voltage signal, that is, perform voltage stabilization on the voltage signal regardless of whether the voltage signal is at a high level or a low level, so as to make the charging system more stable.
Further, between the steps S200 and S300, the method further includes:

Specifically, a voltage detection module may be provided, which detects the voltage signal output by the current-voltage conversion module. When the voltage comparison unit in the voltage detection module compares that the voltage signal is greater than or less than the voltage signal 5V output by the VBUS, the voltage signal output by the current-voltage conversion module is subjected to voltage stabilization processing through the voltage processing module, and the voltage signal of 5V is stably output.
Preferably, the step S300 includes: and S320, when the voltage signal is greater than the output voltage signal of the power line VBUS, performing voltage reduction and stabilization processing on the voltage signal.
In practical application, the central processing unit of the mobile terminal controls the voltage processing module to work, and when the voltage comparison unit in the voltage detection module compares that the voltage signal is greater than the voltage signal 5V output by the VBUS, the voltage signal output by the current-voltage conversion module passes through the voltage reduction and stabilization module to stably output a voltage signal of 5V.

Therefore, no matter whether the current pulse signal is large or small, the mobile terminal can be stably charged, the problem that the current pulse signal generated by instant jitter when the mobile terminal is charged damages a device of the mobile terminal is avoided, the charging stability of the mobile terminal is improved, and the service life is prolonged.
Based on the mobile terminal charging method provided by the embodiment, the invention also provides a mobile terminal charging management system. Referring to fig. 2, the mobile terminal charging system includes:

a current-voltage conversion module 20, configured to convert, when the current pulse signal is detected, the current pulse signal generated by the instantaneous jitter of the mobile terminal into a corresponding voltage signal;
and the voltage processing module 30 is configured to perform voltage stabilization processing or level conversion processing on the voltage signal.
Further, the voltage processing module includes:

Further, the voltage processing module includes:
and the voltage boosting and stabilizing module is used for performing voltage boosting and stabilizing processing on the voltage signal when the voltage signal is smaller than the output voltage signal of the power line VBUS.
The present invention is described in detail below with reference to application examples.
The invention is provided with a current pulse detection module which detects a current pulse signal generated by shaking of the mobile terminal during charging. When the current pulse detection module detects a current pulse signal generated by shaking of the mobile terminal during charging, the current pulse detection module sends a current pulse processing request signal to a central processing unit to request the central processing unit to process the current pulse generated by shaking of the mobile terminal during charging. And the central processing unit calls a current pulse processing instruction according to the current pulse processing request signal, and outputs an enable signal to the level conversion module, so that the current pulse signal is converted into a low level. In practical application, the circuit modules are controlled by a central processing unit.
Further, the current pulse detection module outputs a pulse driving signal to the current-voltage conversion module, and the current-voltage conversion module converts a current pulse signal generated by the instantaneous jitter of the mobile terminal into a voltage signal. Because the voltage signal is a high level signal, the high level voltage signal is converted into a low level signal through the level conversion module, and the low level signal does not damage devices of the charging system.
It should be noted that, when a large current pulse signal is generated on the VBUS of the mobile terminal, the current pulse detection module detects the current pulse signal. And if the current pulse signal is converted into a high-level voltage signal through the current-voltage conversion module and the high-level voltage signal is converted into a low-level signal through the level conversion module, interrupting the charging current to charge the mobile terminal through the VBUS power line.
The invention further provides a voltage detection module which detects the voltage signal output by the current-voltage conversion module. On one hand, when the voltage comparison unit in the voltage detection module compares that the voltage signal is greater than the voltage signal 5V output by the VBUS, the voltage signal output by the current-voltage conversion module passes through the buck-regulator module to stably output a voltage signal of 5V.
In practical application, the voltage reduction and stabilization module is controlled to work by the central processing unit, and when the current-voltage conversion module outputs a voltage signal converted from a current pulse signal generated on a VBUS power line, the voltage detection module sends a first level signal to the central processing unit. And the central processing unit calls a first control instruction according to the first level signal 1, outputs a first control signal to the voltage reduction and stabilization module and controls the voltage reduction and stabilization module to work.
On the other hand, when the voltage comparison unit in the voltage detection module compares that the voltage signal is less than the voltage signal 5V output by the VBUS, the voltage detection module sends a second level signal to the central processing unit. And the central processing unit calls a second control instruction according to the second level signal, outputs a second control signal to the voltage reduction and stabilization module and controls the voltage reduction and stabilization module to stop working.
It should be noted that, the voltage comparison unit in the voltage detection module compares that the voltage signal is less than the voltage signal 5V output by the VBUS, which means that the current pulse signal generated on the VBUS power line is less than the charging current passing through the VBUS power line, and the current pulse signal does not damage the devices of the charging system.
In practical application, when the voltage output by the charger is jittered at the mobile terminal, voltage ripples are generated to interfere the work of the charging system, the voltage detection module detects that the voltage output by the charger is unstable, and the unstable voltage signal needs to be controlled and processed by the voltage reduction and stabilization module.
When the voltage comparison unit in the voltage detection module compares that the unstable voltage signal is greater than the voltage signal 5V output by the charger, the unstable voltage signal passes through the voltage reduction and stabilization module to stably output a voltage signal of 5V.
And when the voltage output by the charger is unstable, the voltage detection module sends a third level signal to the central processing unit. And the central processing unit calls a third control instruction according to the third level signal, outputs a third control signal to the voltage reduction and stabilization module and controls the voltage reduction and stabilization module to work.
When the voltage comparison unit in the voltage detection module compares that the unstable voltage signal is less than the voltage signal 5V output by the charger, a voltage boosting and stabilizing module is arranged and controls the charger to stably output the voltage signal of 5V.
And the voltage detection module sends a fourth level signal to the central processing unit. And the central processing unit calls a fourth control instruction according to the fourth level signal, outputs a fourth control signal to the boosting and voltage stabilizing module and controls the boosting and voltage stabilizing module to work.
It should be noted that, when the voltage comparison unit in the voltage detection module compares that the unstable voltage signal is less than 5V of the voltage signal output by the charger, the voltage signal output by the charger is less than 5V, and the voltage signal when the lithium battery is fully charged cannot reach 4.35V. A voltage boosting and stabilizing module is needed to be arranged to control the charger to stably output a 5V voltage signal.
