Embodiment
For the embodiment of the present invention will be solved technical problem, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiments provide a kind of end cell Activiation method, between the positive pole and the first end of terminal charge input of end cell, control switch is set, wherein said first end is one end that charging input end is connected with described end cell positive pole, described control switch one end is connected to the positive pole of described end cell, and the other end of described control switch is connected to the first end of described terminal charge input;
Described method as shown in Figure 1, comprising:
Step 11, whether the charging input end detecting described terminal is connected with external charging device, obtains the first testing result;
Step 12, when described first testing result indicates the charging input end of described terminal to be connected with external charging device, detects described end cell the need of activation, obtains the second testing result;
Step 13, when described second testing result indicates described end cell to need to activate, control described control switch to close, after making the positive pole conducting of the first end of the charging input end of described terminal and described end cell, first voltage is directly added on described end cell by described external charging device, activates described end cell.
Because the voltage of charging device generally can higher than the scope of normal battery operation voltage.When needs are charged to battery by charging device, need the voltage of charging device to input from charging input end, then pass through the conversion of some electric devices, after being converted to the normal operating voltage range of battery, just battery is charged.The normal voltage range of such as lithium battery is 2.4 volt of-4.2 volt, and the voltage of charging device is generally 5 volts, the voltage of charging device needs the conversion through electric device, after being reduced to the normal operating voltage range of lithium battery (being generally need to be converted to 3.7 volts), can charge to lithium battery.
The embodiment of the present invention make use of above-mentioned principle just, between the charging input end and the positive pole of described end cell of terminal, control switch is set, wherein control switch is without any electric device, is connected directly between the first end of charging input end and the positive pole of end cell.When detect need to activate end cell time, control described control switch to close, make the positive pole conducting of the first end of charging input end and described end cell, now the first voltage of self can directly be added on described end cell by external charging device, utilize the first voltage to carry out activated terminals battery as high pressure, achieve object of the present invention.
It should be noted that because the first voltage is higher than end cell operating voltage, the first voltage is directly added in battery two ends, although can activated batteries, also can cause the capacity of battery and material component etc. simultaneously and affect definitely.This impact is irreversible, and battery finally can be caused to use.
Therefore, to before battery activated, need accurately to judge that end cell is the need of activation.In embodiments of the present invention, preferably, provide a kind of judge end cell the need of activate method, namely step 12 specifically comprises:
Step 121, judges current the second voltage of described end cell whether lower than the minimum voltage threshold value of described end cell, obtains the first judged result;
Step 122, when described first judged result indicates described second voltage of described end cell lower than described minimum voltage threshold value, charges to described end cell with described external charging device;
Step 123, judges whether the tertiary voltage after described end cell charging first time period is greater than described second voltage, obtains the second judged result;
Step 124, when described second judged result indicates described tertiary voltage to be not more than described second voltage, determines that described second testing result is that described end cell needs to activate.
The minimum voltage threshold value of end cell is different from the normal working voltage of battery, if end cell is lower than minimum voltage threshold value, battery is dead electricity easily, and namely voltage cannot fill back again.If current the second voltage of end cell is lower than minimum voltage threshold value, now can judge that end cell needs to activate.
But due to described before, the first voltage is directly added in battery two ends, although can activated batteries, also can causes the capacity of battery and material component etc. simultaneously and affect definitely.In order to reduce the loss to end cell as far as possible, preferably, external charging device is first utilized to charge to end cell, after charging first time period, if the voltage of end cell does not still raise, just now determine that end cell needs to activate.
When determining to need to activate end cell, preferably, control switch can be made to close by transmitting control signal.Namely, in above-mentioned end cell Activiation method, described control switch is closed or disconnection when receiving control signal;
Described step 13 is specially:
When described second testing result indicates described end cell to need to activate, generate the first control signal, and described first control signal is sent to described control switch, make described control switch closed after receiving described first control signal.
Control switch is closed after receiving the first control signal, and the now first end of the charging input end of terminal and the positive pole conducting of end cell, the first voltage can directly be added on described end cell by described external charging device, activates described end cell.
But the first voltage can not be added on end cell for a long time, otherwise can badly damaged end cell.Therefore, control switch needs to disconnect the path between the first end of charging input end and the positive pole of end cell after closed second time period.Namely when after completing steps 13, described method also comprises:
Step 14, after the described control switch of control closed second time period, controls described control switch and disconnects.
Making the method that control switch is closed identical with utilizing control signal, can utilize control signal that control switch is disconnected.Step 14 is specially:
After the described control switch of control closed second time period, generate the second control signal, and described second control signal is sent to described control switch, described control switch is disconnected after receiving described second control signal.
In embodiments of the present invention, the first control signal and the second control signal can be pulse signal, when needing the activation carrying out end cell, send signal value be the digital signal of 1 to control switch, control switch when receiving signal value close.When after control switch closed second time period, stop sending this digital signal, namely now the signal value of digital signal is 0, and control switch disconnects.
Certainly, the first control signal and the second control signal also can be other signal, as long as control switch can be made to close or disconnect.
If utilize aforesaid way repeatedly to activate end cell, can battery be damaged, therefore, when adopting aforesaid way activated batteries, need the restriction activating number of times.Namely, after described second testing result indicates the activation of described end cell needs, described method also comprises:
Judge that the accumulation of described end cell activates number of times and whether reaches default activation number of times, obtain the 3rd judged result;
The described control switch of described control is closed to be specially:
When described 3rd judged result indicates described end cell accumulation activation number of times not reach default activation number of times, control described control switch and close.
As can be seen from said process, during the method activated terminals battery adopting the embodiment of the present invention to provide, do not need end cell to take out separately.Meanwhile, terminal increase only control switch, come compared with activated batteries with the high pressure active circuit that utilizes of the prior art, realize simple and control cost.
