Next, will describe battery management unit 12 in detail according to the processing of the battery status of acquisition the first battery 10 and the second battery 11.
For example, battery management unit 12 can obtain according to first threshold and Second Threshold the battery status of the first battery 10 and the second battery 11.Here, this first threshold and Second Threshold can be all the dump energies of the first battery 10 or the second battery 11.For example, first threshold can be the first battery 10 or the second battery 11 total electric weight 20%, and Second Threshold can be the first battery 10 or the second battery 11 total electric weight 5%.Enumerate the example of first threshold and Second Threshold in the above, but, the invention is not restricted to this, as long as ensure that first threshold is greater than Second Threshold, can also use other threshold value as first threshold and Second Threshold, and can determine based on empirical value or experiment value.Here, battery management unit 12 can obtain by electric weight estimating techniques arbitrarily the dump energy of the first battery 10 and the second battery 11, and total electric weight of dump energy that can be based on the first battery 10 and the second battery 11 and the first battery 10 and the second battery 11 is determined the relation between dump energy and first threshold and the Second Threshold of the first battery 10 and the second battery 11.
Particularly, if battery management unit 12 determines that the dump energy of the first battery 10 is greater than the first threshold of the first battery 10, battery management unit determines that 12 first batteries 10 are in high state of charge (electric weight is greater than 20%).Similarly, if battery management unit 12 determines that the dump energy of the second battery 11 is greater than the first threshold of the second battery 11, battery management unit 12 determines that the second battery 11 is in high state of charge.

Here, terminal equipment 1 can also comprise the first output port 13 and the second output port 14.The first output port 13 can be with the lower voltage components of the terminal equipment 1 such as internal memory, processor, mainboard (, needing lower operating voltage) coupling to power to said elements.In addition, the second output port 14 can be with the high voltage devices of the terminal equipment 1 such as display screen (, needing higher operating voltage) coupling to power to said elements.
According to embodiments of the invention, battery management unit 12 can be controlled by controlling on/off between the first battery 10 and the second battery 11 and the first output port 13 and the second output port 14 power supply of the first battery 10 and the second battery 11.To battery management unit 12 be described according to the situation of the on/off between different conditions control first battery 10 of the first battery 10 and the second battery 11 and the second battery 11 and the first output port 13 and the second output port 14 below.
Particularly, for example, if battery management unit 12 determines that the first battery 10 and the second battery 11 are all in high state of charge, battery management unit 12 is connected the first battery 10 and the first output port 13, and the second battery 11 and the second output port 14 are connected.In addition, battery management unit 12 disconnects the first battery 10 and the second output port 14, and the second battery 11 and the first output port 13 are disconnected.In this case, because the voltage of the second battery 11 is higher than the first battery 10, therefore in the time that the second battery 11 and the second output port 14 are connected, second battery 11 with higher output voltage is connected with the element that needs higher operating voltage, therefore because the pressure reduction between second output voltage of battery 11 and the operating voltage of this class component is less, therefore in the time that the voltage conversion unit of the element of the higher operating voltage of needs carries out voltage transitions, can not produce larger energy loss, can effectively increase thus the flying power of terminal equipment 1.
If battery management unit 12 determines that the first battery 10 is in high state of charge, and the second battery 11 is in low state of charge or dangerous state of charge, battery management unit 12 is connected the first battery 10 and the first output port 13 and the second output port 14, the second battery 11 and the first output port 13 and the second output port 14 is disconnected simultaneously.In this case, can avoid because the second battery 11 electric weight deficiencies cause the element of operating voltage that need to be higher to shift to an earlier date the generation of the situation of power-off.
If battery management unit 12 determines that the first battery 10 is in low state of charge or dangerous state of charge, and the second battery 11 is in high state of charge, battery management unit 12 is connected the second battery 11 and the first output port 13 and the second output port 14, the first battery 10 and the first output port 13 and the second output port 14 is disconnected simultaneously.In this case, can avoid because the first battery 10 electric weight deficiencies cause the element of operating voltage that need to be lower to shift to an earlier date the generation of the situation of power-off.
In addition,, if battery management unit 12 determines that the first battery 10 and the second battery 11 are all in low state of charge, battery management unit 12 is connected the first battery 10 and the first output port 13, and the second battery 11 and the second output port 14 are connected.In this case, battery management unit 12 also disconnects the first battery 10 and the second output port 14, and the second battery 11 and the first output port 13 are disconnected.In addition, if battery management unit 12 determines that one of the first battery 10 and second battery 11 are in low state of charge, and another battery in the first battery 10 and the second battery 11 is in dangerous state of charge, battery management unit 12 produces off signal that indicating terminal equipment 1 shuts down to prevent that subelement on terminal equipment 1 is because power-off suddenly damages or produce the situation of loss of data.
By above-mentioned configuration, can be in the time that the electric weight of the first battery 10 and the second battery 11 be sufficient, by second battery 11 with higher output voltage is connected with the element that needs higher operating voltage, and by have compared with the first battery 10 of low output voltage with need to be connected and can effectively avoid in the time carrying out voltage transitions the energy loss that causes too greatly due to the pressure reduction of output voltage and operating voltage compared with the element of low operating voltage, can greatly improve thus the flying power of terminal equipment 1.In addition, can also the first battery 10 and the different conditions of the second battery 11 different supply power modes is set neatly, make full use of thus the electric weight of the first battery 10 and the second battery 11 to maximize the flying power of terminal equipment 1.

As shown in Figure 1, the two ends of the first switch 15 can be connected with the first output port 13 with the first battery 10 respectively.The two ends of second switch 16 are connected with the second output port 14 with the first battery 10 respectively.The two ends of the 3rd switch 17 are connected with the first output port 13 with the second battery 11 respectively.In addition, the two ends of the 4th switch 18 are connected with the second output port 14 with the second battery 11 respectively.In this case, can control by the conduction and cut-off of the first switch 15, second switch 16, the 3rd switch 17 and the 4th switch 18 on/off of the first battery 10 and the second battery 11 and the first output port 13 and the second output port 14.
Particularly, in the time that needs are connected the first battery 10 and the first output port 13, the first switch 15 conductings.In the time that needs are connected the first battery 10 and the second output port 14, second switch 16 conductings.In the time that the second battery 11 and the first output port 13 are connected, the 3rd switch 17 conductings.In addition, in the time that the second battery 11 and the second output port 14 are connected, the 4th switch 18 conductings.
In addition, in the time that needs disconnect the first battery 10 and the first output port 13, the first switch 15 ends.In the time that needs disconnect the first battery 10 and the second output port 14, second switch 16 ends.In the time that the second battery 11 and the first output port 13 disconnect, the 3rd switch 17 ends.In addition,, in the time that the second battery 11 and the second output port 14 disconnect, the 4th switch 18 ends.
In this case, battery management unit 12 can be controlled according to the conduction and cut-off of different conditions control the first switch 15, second switch 16, the 3rd switch 17 and the 4th switch 18 of the first battery 10 and the second battery 11 on/off of the first battery 10 and the second battery 11 and the first output port 13 and the second output port 14.
