[being applied to the charging method of terminal equipment]
Below, the charging method being applied to terminal equipment of the present invention is described by reference to the accompanying drawings in detail.Fig. 2 is the flow chart of the charging method being applied to terminal equipment according to an embodiment of the invention.As shown in Figure 2, the method comprises:
First, whether detection has charge power supply to be connected to described first interface (step S210).Terminal equipment can be charged by first interface, but first interface is not limited to the interface being exclusively used in charging, can also be not only chargeable but also can transmit the interface of data.Typically, first interface can be USB interface, Mini-USB interface, Micro-USB interface, Lightning interface, but also can be other any interfaces with charge function.When not detecting that charge power supply is connected to interface (step S210, no), turning back to step S210 and continuing to detect whether be connected to first interface by charge power supply.
Being (step S210, yes) when detecting that charge power supply is connected to first interface, charging can be started.Now, terminal equipment can control charging current make the size of charging current according to regulation wave form varies.Below, an example of the electric current of the wave form varies according to regulation is described.In this example, according to the electric current of wave form varies of regulation for be increased to the second current value from the first current value notch cuttype, described first current value is dropped to from described second current value notch cuttype subsequently.Fig. 3 is the figure of an example of the charging current of the wave form varies represented according to regulation.In figure 3, abscissa representing time, ordinate represents the size of electric current.As shown in Figure 3, first charging current can be controlled for 200mA, through stopping 500ms after a period of time, subsequently charging current risen to 400mA and again stop 500ms through after a period of time, by that analogy, often increase 200mA and stop 500ms through after a period of time, thus notch cuttype is increased to 1800mA.Control current value notch cuttype subsequently to decline, often decline 200mA and stop 500ms through after a period of time, until charging current drops to 200mA.Obviously, be not limited to the waveform shown in Fig. 3 according to the electric current of the wave form varies of regulation, but the waveform that preferably can distinguish with curent change waveform when charging normal.
