Voltage in the power pins how determining described charging inlet is specifically determined that mode does not limit by present embodiment.As an implementation, voltage detecting circuit it is provided with in electronic equipment, this voltage detecting circuit electrically connects with the power pins of charging inlet, voltage detecting circuit in the process of battery core charging is detected the voltage of the power pins of charging inlet in real time, and the Voltage Feedback detected is controlled module.Preferably, this voltage detecting circuit is located in control module, the voltage detecting circuit controlled in module detects the voltage of the power pins of charging inlet in real time.
Under normal circumstances, the charging voltage that battery core can bear is certain, and the voltage of the signal of telecommunication that power supply unit exports to electronic equipment is greater than the charging voltage that battery core can bear, if charging circuit is short-circuit, the voltage of power supply unit output can directly be imposed in battery core, the voltage of power supply unit output can directly be imposed in battery core, and whether battery core is full of all is charged by force to battery core, damages battery core.
Additionally, if charging circuit is short-circuit, because of battery core be directly over the charging circuit of short circuit, the switch module of conducting electrically connect with the power pins of charging inlet, the voltage of battery core is understood direct by the voltage pull-down of the power pins of charging inlet, cause that the power pins of charging inlet is greatly reduced.Therefore, the voltage that present embodiment has been rushed according to battery core under the different charging stages determines described first voltage threshold, the voltage that described first voltage threshold determined has rushed higher than battery core, during concrete application, the experimental data such as the impedance of internal circuit according to switch module determines this first voltage threshold.

Under normal circumstances, the charging voltage that battery core can bear is certain, if the voltage of the signal of telecommunication that power supply unit exports to electronic equipment is greater than the charging voltage that battery core can bear, such as charging circuit short circuit, the voltage of power supply unit output can directly be imposed in battery core, whether battery core is full of all is charged by force to battery core, damages battery core.
Therefore, the upper limit of the charging voltage that present embodiment can bear in the different charging stages according to battery core determines described second voltage threshold, it is determined that the charging voltage that can bear more than battery core of this second voltage threshold.
Illustrate, at constant voltage charging phase, it is determined that the second voltage threshold more than battery core voltage under having been filled with state.
It addition, in battery core under having been filled with state, also determine the second voltage threshold, it is determined that the second voltage threshold more than battery core voltage under having been filled with state.So, when battery core has been filled with, if charging circuit is short-circuit, but do not disconnect the charge circuit to battery core charging yet；Power supply unit is forced the voltage in battery core through short-circuit charging circuit and more than battery core voltage under having been filled with state, can be forced the voltage in battery core and can reach the second voltage threshold, meets the condition provided.
