Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
The embodiment of the present invention provides a kind of electric quantity of lithium ion batteries display packing, and as shown in Figure 1, this display packing comprises the steps:
Step 101, reads battery voltage value U, draws battery initial quantity of electricity cp according to lithium ion battery charging and discharging curve.
In this step, lithium ion battery charging and discharging curve is drawn by the inherent feature of lithium ion battery, but in order to ensure that lithium ion battery charging and discharging curve is more close to actual conditions, can take multiple measurements lithium ion battery, drawing out lithium ion charging and discharging curve according to repetitive measurement value, as shown in Figure 2, is the charging and discharging curve of lithium ion battery described in this step figure, the curve being wherein positioned at top is voltage curve, and the curve being positioned at below is current curve.By this curve chart, we can see the corresponding relation of lithium ion battery voltage, electric current, therefore, after reading battery voltage value U, battery initial quantity of electricity cp can be drawn by the characteristic of the lithium ion battery charging and discharging curve shown in Fig. 2, make initial quantity of electricity cp=current electric quantity dp.
Step 102, detects cell current value I, judges the charging and discharging state of battery according to current value I.
In this step, detect cell current value I, those skilled in the art can build current detection circuit by current detecting instrument or voluntarily, determine that battery is in charged state or discharge condition according to the size direction of current value I, therefore, the concrete circuit structure judging the charging and discharging state of battery according to current value I is repeated no more.In this step, when battery is in discharge condition, then enters into step 103 and do further process; When battery is in charged state, then enters into step 104 and do further process.
Step 103, carries out timing to Tf discharge time.Once judge that battery is in discharge condition in a step 102, then need to start immediately to carry out timing to Tf discharge time, be understandable that, discharge time, Tf reset, therefore, give current electric quantity dp-cell current value I* Tf discharge time of current electric quantity dp=last time in step 105, reset Tf discharge time.Can find out, each current electric quantity dp upgrades, and discharge time, Tf can be cleared, and made battery in the discharged condition, and current electric quantity dp keeps real-time status.
In the discharged condition, along with the accumulation of Tf discharge time, current electric quantity dp can reduce gradually, therefore, the mistake preventing battery is needed to put, and in step 107, then judge whether that current electric quantity dp is less than or equal to 0, owing to being obtained by the inherent characteristic curve of lithium ion battery to the initial quantity of electricity cp of battery in previous step 102, therefore, some deviations may be there are for different batteries, therefore, on current electric quantity dp=current electric quantity dp-cell current value * Tf discharge time once condition under, current electric quantity dp there will be less than 0 and equal 0 situation, charged state is transferred to owing to may stop electric discharge at certain stage battery, or (mobile phone communication or take pictures the stage) causes electricity to be beated to occur that battery load current increases suddenly, therefore, when judging that current electric quantity dp is greater than 0 in step 107, then illustrate that the electricity of battery is not released complete, need to turn back to the charging and discharging state again judging battery in step 102, current electric quantity dp is upgraded further, if judge in step 107 that current electric quantity dp is less than or equal to 0, then illustrate that the electricity of battery is close to spent condition, but now can not conclude battery just discharge off completely, because also there is the situation that above-mentioned electricity is beated, therefore also must do further process, namely step 109 couple current electric quantity dp does and further sentences again: judge whether that cell voltage U is less than battery operated lower voltage limit Ux.Battery operated lower voltage limit Ux is also an inherent characteristic of lithium ion battery, can find out that from battery charging/discharging characteristic curve battery operated lower voltage limit Ux is the magnitude of voltage ensureing normal battery operation, if battery works at battery operated below lower voltage limit Ux for a long time, the working life of battery can be had a strong impact on, and battery operated lower voltage limit Ux is at about 3.1V, according to the property difference of indivedual lithium ion battery, battery operated lower voltage limit can be 3.0V ~ 3.2V, and battery operated lower voltage limit gets 3.1V in the embodiment of the present invention, electric power detection requirement can be met.
In step 109, if cell voltage U is more than or equal to battery operated lower voltage limit Ux, i.e. U >=3.1V, then illustrates that the electricity of battery there occurs and beat, what current electric quantity was inreal releases to 0, therefore also needs to return in step 102 to make further judgement.
And in embodiments of the present invention, in order to demonstrate the numerical value of current electric quantity dp more accurately in real time, when step 109 judges that cell voltage U is more than or equal to battery operated lower voltage limit Ux, enter into step 113: display electricity is 1%, and then turns back in step 102 and judge battery charging condition further.
If in step 109, cell voltage U is less than battery operated lower voltage limit Ux, then after the double standards that electricity judges and voltage is sentenced again, can conclude that the current electric quantity dp of battery is inevitable has released totally, therefore, enter into step 111: discharge off, display battery electric quantity is 0%.
So far, by the agency of is complete for battery step display in the discharged condition, next introduces battery step display in the charge state.
Step 104, carries out timing to charging interval Tc.Once judge that battery is in charged state in a step 102, then need to start immediately to carry out timing to charging interval Tf, be understandable that, charging interval Tc resets, therefore, give the current electric quantity dp+ cell current value I* charging interval Tc of current electric quantity dp=last time in step 106, reset charging interval Tc.Can find out, each current electric quantity dp upgrades, and charging interval Tc can be cleared, and makes battery in the charge state, and current electric quantity dp keeps real-time status.
In the charge state, along with the accumulation of charging interval Tc, current electric quantity dp can increase gradually, therefore, need to prevent overcharging of battery, therefore in step 108, can judge whether that current electric quantity dp is less than the true electricity dz of battery, the true electricity dz of battery is battery parameter value inherently, therefore when current electric quantity dp is less than battery true electricity dz, then illustrate that battery is not yet full of, and therefore turns back to step 102 and makes further judgement.If when current electric quantity dp is more than or equal to battery true electricity dz, then illustrate that battery is close to being full of, but it is complete now can not to conclude that battery has just charged completely, because also there is the situation that above-mentioned electricity is beated, therefore also further process must be done, namely step 110 couple current electric quantity dp does and further sentences again: judge whether cell voltage U >=4.2V and cell current value I ﹤ 100mA, in step 110, if cell voltage U is less than 4.2V and battery current I is more than or equal to 100mA, then illustrate that the electricity of battery there occurs to beat, what current electric quantity was inreal is filled to 100%, therefore also need to return in step 102 to make further judgement.
If in step 110, cell voltage U is more than or equal to 4.2V and battery current I is less than 100mA, then after the double standards that electricity judges and voltage, electric current are sentenced again, can conclude that the current electric quantity dp of battery is inevitable to be full of, therefore, enter into step 112: charge complete, display battery electric quantity is 100%.
Certainly, be understandable that, in the embodiment of the present invention, display 0% or display 100% can adopt " discharge off " or " charging complete " to substitute, and are the change in display format herein, therefore still belong in protection scope of the present invention.
