Here, complete saying has been carried out to the charging process of the first battery 21 and the second battery 22 by interface circuit 23 Bright, below the second battery 22 is illustrated to the charging process of the first battery 21.

Second battery 22 is charged to the first battery 21, needs defeated to the second battery 22 through charge inside circuit 24 Go out after electric current carries out being converted to the first battery 21 voltage threshold and just the first battery 21 to be charged, charge controller 25 is according to filling The situation that in electric process, real-time detection arrives controls whole charging process.

First, external power source is charged to the first battery 21 and the second battery 22 by interface circuit 23, charge control The first battery 21 current electric quantity monitored by device 25, when the first battery 21 current electric quantity reaches preset charged charge value, judges second Whether battery 22 current electric quantity is more than or equal to the first battery 21 electricity to be charged, if it is, charge controller 25 disconnects the first electricity Pond 21 and the connection of external power source, and control the second battery 22 that first battery 21 is charged.Charge controller 25 is simultaneously Can notify mobile terminal display interface that the first battery 21 capacity is shown as full state, to remind user that electricity has filled Full, now user can disconnect the connection of external power source and terminal, reduce user and wait the charging interval.Judge that the second battery 22 is worked as When front electricity is less than the first battery 21 electricity to be charged, the company of the first battery 21 and the external power source charging for it can be disconnected Connect, only the second charging 22 is charged it is also possible to be charged to the two simultaneously, until the second battery disclosure satisfy that to first Till battery charges.

Wherein, preset charged charge value could be arranged at least the 50% of the first battery 21 power threshold, such as 90%, 95%th, 99% etc..In order to be better understood from, it is assumed that preset charged charge value is set to 90%, below this being described further:

The power threshold of the first battery 21 is 100w.h (watt-hour), then preset charged charge value is 100w.h*90%= 90w.h (watt-hour), the second battery 22 current electric quantity 10w.h (watt-hour), then the second battery 22 current electric quantity is equal to the first battery 21 electricity (100*10%=10w.h) to be charged, do not consider charging conversion efficiency and the loss of charge inside circuit 24, can be by First battery 21 electricity is completely filled with.Now, user simply waits for the time that the first battery 21 electricity is charged to 90%, and other 10% Electricity to be charged can be full of by the second battery 22, be conducive to improve user experience.

It should be appreciated that if the second battery 22 power threshold is suitably less than the first battery 21 power threshold, and second Battery 22 voltage threshold is more than the first battery 21 voltage threshold, and the setting of preset charged charge value is suitable, and charge controller 25 also may be used Not judge whether the current dump energy of the second battery 22 is more than or equal to the first battery 21 electricity to be charged.For example, the second electricity Pond 22 power threshold is 20w.h (watt-hour), and the first battery 21 power threshold is 100w.h (watt-hour), and preset charged charge value is the 98% (100w.h*98%=98w.h) of one battery 21 power threshold, then, the second battery 22 power threshold 20w.h is more than the One battery 21 electricity 2w.h to be charged, in this case, typically can meet the current dump energy of the second battery 22 be more than etc. In the first battery 21 electricity to be charged, so process can not also be made a decision.

When charge controller 25 judges that the second battery 22 current electric quantity is less than the first battery 21 electricity to be charged, control of charging Device 25 processed controls second interface to connect the second charge switch circuit 38 of circuit 36 or internal second voltage threshold value charging circuit 43 the 4th charge switch circuit 45 closes, and continues as the second battery 22 and is charged, at this time it is also possible to simultaneously to the first battery 21 are charged.Until charge controller 25 judges that the second battery 22 current electric quantity is more than or equal to the first battery 21 electricity to be charged When, charge controller 25 disconnects the connection of the first battery 21 and the second battery 22 and external charging power supply, then controls the second electricity Pond 22 is charged to the first battery 21.It should be appreciated that when the first battery 21 fills with, and the second battery 22 does not also reach To the first battery 21 reach the electricity to be charged during default charge value when, charge controller 25 disconnect the first battery 21 fill with outside The connection of power supply.

Wherein, the second battery 22 is charged needing to the first battery 21 by charge inside circuit 24, charge inside electricity Road 24 is referred to Fig. 6, fills including the builtin voltage change-over circuit 61 being connected and inside with the second battery 22 and the first battery 21 Electric switch circuit 62.When charge controller 25 judges that the first battery 21 current electric quantity reaches preset charged charge value, charge control Device 25 controls charge inside on-off circuit 62 to close, and the output current signal of the second battery 22 is turned by builtin voltage change-over circuit 61 Be changed to the charging voltage needed for the first battery 21, complete the second battery 22 and first battery 21 is charged, to be charged after the completion of, Charge controller 25 controls charge inside on-off circuit 62 to disconnect.

It should be appreciated that builtin voltage change-over circuit 61 can be dc-dc (direct current-direct Current, DC-DC) transducer, the direct current output of the second battery 22 is converted to after the charging current of the first battery 21 First battery 21 is charged.Charge inside on-off circuit 62 can be controlling switch, and charge controller 25 can control interior The disconnection of portion's charge switch circuit 62 and closure.

In the present embodiment, by charge controller 25 control interface 23 to the first battery 21 of mobile terminal 2 and Two batteries 22 are charged, and judge to reach preset charged charge value when the first battery 21 electricity, and the current electricity of the second battery 22 When amount is more than or equal to the first battery 21 electricity to be charged, charge controller 25 controls the first battery 21 and the external electrical charging for it The connection in source, and control the second battery 22 that first battery 21 is charged, treat the first battery 21 charging complete, control internal filling Circuit 24 disconnects the connection of the second battery 22 and the first battery 21.Charge controller 25 can also notify mobile terminal to show simultaneously Show that the first battery 21 capacity is shown as full state by interface, to remind user that electricity fills with, reduce user etc. to be charged Time.
