That is to say, when the predicted operating time of the B terminal is equal to or less than the predicted operating time of the a terminal (i.e. the first condition), the first control unit of the a terminal controls the first switching unit to select the first battery unit to supply power to the a terminal.
Referring to fig. 6, an application flowchart of power supply when the terminal a and the terminal B are connected according to an embodiment of the present invention is shown. In this embodiment, the units included in the terminal a and the terminal B and the connection relationship thereof are described in detail in fig. 3, and are not described herein again. In this embodiment, the first condition is, for example and without limitation, that a ratio of the second energy information to the first energy information is greater than a ratio of the second power information to the first power information, where the first energy information is functionally equivalent to the first power consumption information, and the first switching unit is functionally equivalent to the first power switching unit, and the method includes:
step 601: combining the terminal A and the terminal B:
step 602: the second control unit of the terminal B reports the first power consumption information of the current working mode of the terminal B and the second power information of the second battery unit to the first control unit of the terminal A;
step 603: the first control unit receives second power consumption information and second electric quantity information of the terminal B in the current working mode, which are sent by the second control unit, and the obtained first power consumption information of the terminal A in the current working mode and the first electric quantity information of the first battery unit, and calculates the ratio N of the first power consumption information and the second power consumption information, namely a comparison threshold value factor;

In the above embodiment, when the terminal a and the terminal B are combined, the second control unit of the terminal B reports the second power consumption information of the current working mode of the terminal B and the second power information remaining in the second battery unit to the first control unit of the terminal a in real time, after the first control unit of the terminal a obtains the second power consumption information and the second power information of the terminal B in the current working mode, it calculates whether the first energy information, the first power information, the second energy information, and the second power information satisfy the first condition or the second condition according to a certain algorithm by combining the first power consumption information and the first power information remaining in the first battery unit in the current working mode of the terminal a itself, and if the first condition is satisfied, the first control unit controls the first power switching unit to select the second battery unit to supply power to the terminal a; and if the second condition is met, the first control unit controls the first power supply switching unit to select the first battery unit to supply power for the device A. Therefore, the embodiment prolongs the time for the terminal a to work independently while prolonging the cooperative working time of the terminal a and the terminal B. That is to say, the embodiment of the invention can not only prolong the cooperative working time of the terminal A and the terminal B as much as possible; and the terminal A which cannot share the battery can be ensured to reserve the battery energy as much as possible, and the time for the terminal A to work independently is prolonged.
Furthermore, the present invention is described below in terms of specific examples to facilitate understanding by those skilled in the art.
In the example, the Base is connected with the Slate, the full charge energy of the Slate battery is 25 watt-hour (wh), the full charge energy of the Base battery is 27 watt-hour (wh), the power consumption of the Slate is always 3 watt, and the power consumption of the Base is always 9 watt.
In the case that the residual electric energy of the Slate battery is 5 watt-hours, if the Slate and the Base are combined, the control unit of the Slate can obtain the current residual electric energy of the Base battery and the current power consumption value of the Base.
If the residual electric energy of the Base battery is 20 watts at the moment, the control unit of the Slate controls the switching unit to supply power to the Slate by using the battery of the Base. Meanwhile, the battery of the Base also supplies power to the Base.
Then, since the Base battery supplies power to the Base and the Slate at the same time, when the electric energy of the Base battery drops to 15 watts, the control unit of the Slate controls the switching unit to supply power to the Slate by using the battery of the Slate, namely, the battery of the Slate supplies power to the Slate, and the Base battery supplies power to the Base.
When the Slate battery discharges to 0.75 watt-hour (3%. 25 watt-hour), the control unit of the Slate controls the switching unit to supply power to the Slate by using the battery of the Base again until the battery of the Base supplies the discharging energy to the Base and the Slate simultaneously.
Therefore, the embodiment can not only prolong the time of cooperative work of Base and Slate; and the Slate which cannot share the battery can be ensured to reserve the battery energy as much as possible, so that the time for the Slate to work independently is prolonged.
It is further noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
