101, when detecting charging interface exception, obtain current charge mode.
Wherein, charging interface 310 is for connecting external recharging apparatus 200.Charging interface 310 can be universal serial bus(Universal Serial Bus, USB) interface.Specifically, charging interface 310 can be Micro USB interface or Type-CInterface etc., certainly, charging interface 310 or other interfaces.Charging interface 310 connects external charging by charging cable lineDevice 200, and electric energy is obtained from external recharging apparatus 200.External recharging apparatus 200 can be the devices such as adapter.
Wherein, charging interface 310 includes multiple pins, including power input pin VBUS.First switching element 370The first control terminal 3713 be turned on or off between first input end 3711 and the first output end 3712 for controlling, to realizeThe power input pin VBUS and the input terminal of battery 330 of charging interface 310 are turned on or off, and the power supply of charging interface 310 is defeatedWhen entering pin and being connected with the input terminal of battery 300, the electric signal of external recharging apparatus 200 charges directly to battery 330, at this time forFast charge mode.
Wherein, the abnormal temperature that may include charging interface 310 of charging interface 310 is more than reliability temperature threshold, chargingThe voltage of mouth 310 is more than safe voltage thresholds or is less than minimum voltage threshold, and the electric current of charging interface 310 is more than safe current thresholdValue is less than minimum current threshold value, and the impedance of charging interface 310 is beyond safety impedance threshold value or less than in minimum impedance threshold valueAt least one of.
102, when current charge mode is fast charge mode, control instruction is generated, and control instruction is transmitted to outside and is filledElectric installation stops input charging signals to control external recharging apparatus.
When charging circuit is in fast charge mode, and charging interface 310 is abnormal, control instruction is generated, and by control instructionIt is transmitted to external recharging apparatus 200 by charging interface 310, stops input charging signals to control external recharging apparatus 200.FromThe external of device 200 to be charged stops providing charging signals, does not need the power input pin VBUS of charging interface 310 is directGround connection, to avoid result in the input end grounding of battery 330, prevents 300 system entirety power down of charging equipment.It both can be quickStop charging, protects charging interface 310, and 300 system entirety power down of charging equipment will not be caused because of battery ground.
In some embodiments, when current charge mode is fast charge mode, control instruction is generated, and control instruction is passedExternal recharging apparatus 200 is transported to, to control the step of external recharging apparatus 200 stops input charging signals, can also include:
When current charge mode is fast charge mode, fast charge mode is exited, into normal charging mode；
Control instruction is generated, and control instruction is transmitted to external recharging apparatus 200, to control external recharging apparatus 200Stop input charging signals.
Charging equipment 300 can first exit fast charge mode and enter normal charging mode, while generate control instruction, controlInstruction stops input charging signals for controlling external recharging apparatus 200.
Charging equipment 300 supports commonly to charge or fast charge both of which, external recharging apparatus 200 can also be supported commonlyCharging and fast charge both of which.When external recharging apparatus 200 and charging equipment 300 are fast charge mode, charging interface 310Power input pin VBUS connection external recharging apparatus 200, the power input pin VBUS of charging interface 310 be also directly connected to orBattery is connected by first switching element 370.The electric energy of external recharging apparatus 200 is directly filled to the battery of charging equipment 300, energyEnough realize powerful fast charge.Meanwhile without by electricity between external recharging apparatus 200 and the battery 330 of charging equipment 300Pond managing chip 382, if when such as Type-C interface has foreign matter or feed liquor body to charging interface 310, Type-C interfaceIt will appear short circuit between pin, since under straight mold filling formula, the power input pin VBUS of charging interface 310 is directly electrically connected with batteryIt connects, there is no battery management chip 382 to be protected between charging interface 310 and battery, short circuit, which occurs, for Type-C interface will lead toElectric current is excessive and easy in a short time burns Type-C interface and charging equipment 300.After exiting fast charge mode, chargingThe power input pin of interface 310 connects battery by battery management chip 382, is commonly charged, then by the second inputEnd 3731 is connect with second output terminal 3732, is shorted the power input pin VBUS of charging interface 310 and ground, is stopped to realizeOnly charge.And then protect charging interface 310 and device to be charged 200.
In some embodiments, when detecting that charging interface 310 is abnormal it the step of, can specifically include:
The parameter value of charging interface 310 is obtained in real time, and parameter value is at least one in current value, voltage value and impedance value?；
