Abstract
The present invention discloses a cell on-position detecting method for a terminal device in order to solve the problem of the prior art that misjudgement exists when the method determines whether the cell is on position or not. In the method, a high threshold value and a low threshold value are set; then a charging circuit is switched off, and the first voltage of the port of the cell is detected; the charging circuit is switched on, and the second voltage of the port of the cell is detected; finally, the first voltage and the second voltage are respectively compared with the low threshold value and the high threshold value, and if the first voltage is lower than the low threshold value and the second voltage is higher than the high threshold value, the method determines that the cell is not on position, otherwise the method determines that the cell is on position. The method provided by the present invention can exactly judge whether the cell is on position or not, and avoid that the cell is on position, but misjudgement for whether the cell is on position or not exists because the voltage of the cell is lower or a protecting circuit in the cell is switched off.
Description
Technical field
The present invention relates to the detection technique of moving communicating field, specifically refer to a kind of battery method whether on the throne of sense terminals equipment.
Background technology
In general terminal device, all be furnished with adapter (ADAPTER) and battery, design charging circuit simultaneously, finish the charging conversion to battery by ADAPTER, need this moment to judge whether battery is on the throne.
At present, judge the method that battery is whether on the throne, as shown in Figure 1, turn off charge switch preestablishes battery threshold voltage not on the throne simultaneously, carries out the detection of cell voltage then, if detected cell voltage is lower than this threshold value, think that promptly battery is not on the throne.
This kind method can accurately not judge whether battery is on the throne really; because in some cases; the voltage of possible battery is very low; or the holding circuit of inside battery disconnects (after the charging; holding circuit can be connected); whether on the throne even at this moment battery is on the throne, detected cell voltage is also very low, detect battery erroneous judgement thereby cause.
Summary of the invention
The invention provides a kind of battery method whether on the throne that detects accurately, determining that to solve in the prior art whether on the throne battery exist the disconnected problem of erroneous judgement in the when of.
For addressing the above problem, the invention provides following scheme:
1, whether on the throne a kind of battery of sense terminals equipment method comprise the steps:
(1) voltage according to the actual charging of battery is provided with wealthy family's limit value, according to the sparking voltage of electric capacity in detection time of battery port threshold ones is set;
(2) disconnect charging circuit and detect first voltage of battery port;
(3) connect charging circuit and detect second voltage of battery port;
(4) relatively, second voltage is compared with the wealthy family limit value,, determine that then battery is not on the throne, otherwise definite battery is on the throne if first voltage is lower than threshold ones and second voltage is higher than wealthy family's limit value with first voltage and threshold ones.
First voltage of the detection battery port in the described step (2) disconnects charging circuit detection again after a period of time.
Connection in disconnection in the step (2) and (3) is removed to control charge switch by software or hardware signal and is realized.
The beneficial effect that the present invention brings is:
1, whether on the throne whether on the throne in the present invention if can detect battery accurately, avoids battery itself on the throne, but because the voltage of battery is lower or the holding circuit of inside battery disconnects, thereby detected cell voltage is very low, and cause battery erroneous judgement.
2, whether on the throne the present invention can avoid battery erroneous judgement, thereby carry out follow-up action accurately, for example cell voltage carried out the charging of little electric current, the better protect battery.
Description of drawings
Fig. 1 is the structural representation under the charge switch off-state of the present invention.
Fig. 2 is the structural representation under the charge switch closure state of the present invention.
Embodiment
The present invention carries out twice detection to cell voltage and judges whether battery is on the throne by opening and turn-offing of control charging circuit.
Be earlier default two threshold values of voltage of battery before detecting, one is threshold ones, and one is wealthy family's limit value.Wealthy family's limit value is set according to the voltage of the actual charging of battery, and threshold ones is determined according to the situation of circuit discharging.For example: actual charging voltage is 12V, considers that the ratio of precision such as the lower limit of charging voltage is 11.5V, takes the precision of voltage detecting circuit into consideration, does a surplus, and wealthy family's limit value can be got 11V.Low threshold voltage is considered the sparking voltage of capacitance discharges in detection time of battery port, and not on the throne as the theoretical analysis battery, the voltage of battery is 0.5V in the time of this voltage of software detection, and the precision that combined circuit detects is considered surplus, desirable 1.5V.
Twice testing process is as follows:
1, as shown in Figure 1, disconnect charging circuit by software or hardware signal control charge switch, disconnect charging circuit after a period of time, the capacitor discharge of battery port finished substantially and (mainly was that general circuit has the electric capacity parallel connection, determines according to the capacitance discharges time in practice this moment.), carry out the detection of cell voltage again, if detected cell voltage then satisfies battery first condition not on the throne less than the threshold ones of setting.
2, as shown in Figure 2, by software or the closed charging circuit of hardware signal control charge switch, this moment, charging circuit was connected, the voltage of adapter (ADAPTER) output directly is added to battery port by switch, charging circuit, detect cell voltage, if detected cell voltage then satisfies battery second condition not on the throne greater than wealthy family's limit value of setting.
If the condition in 1 and 2 satisfies simultaneously, the voltage that is battery satisfies simultaneously after turn-offing charging circuit, the battery port voltage that detects is lower than the threshold ones of setting, is connecting wealthy family's limit value that the battery port voltage that detects behind the charging circuit is higher than setting, and it is on the throne to think that then battery does not have; If in the time of can not satisfying above two conditions simultaneously, determine that then battery is on the throne.
The beneficial effect that the present invention brings is:
1, whether in place in the present invention if can detect accurately battery, avoids battery itself in place, but because electricity The voltage in pond holding circuit lower or inside battery disconnects, thereby the cell voltage that detects is very low, and leads Send a telegraph whether erroneous judgement in place of pond.
2, the present invention can avoid whether erroneous judgement in place of battery, thereby carries out accurately follow-up action, example As cell voltage is carried out the charging of little electric current, protect preferably battery.
Obviously, those skilled in the art can carry out various changes and modification to method of the present invention and not take off From the spirit and scope of the present invention. Like this, if of the present invention these revise and modification belongs to right of the present invention Require and the range of equivalent technologies, then the present invention also be intended to comprise these change and modification interior.
