Embodiment
For above-mentioned and other purposes of the present invention, feature, advantage and embodiment can be become apparent, appended accompanying drawing is described in detail as follows:
Fig. 1 is the flow chart of charging method of the present invention.At first, judge whether a rechargeable battery is connected (step S110) with a charger.If when charger is not connected with rechargeable battery as yet, then continue execution in step S110.When rechargeable battery is connected with charger, then provide a predetermined rechargeable electrical energy current potential to give rechargeable battery, in order to carry out first charging procedure (step S120).After finishing first charging procedure, the user can take out rechargeable battery and use this battery from charger.
Should can be electric current current potential (current level) or voltage potential (voltagelevel) by predetermined rechargeable electrical energy current potential.In a possibility embodiment, when the voltage of rechargeable battery does not reach a voltage setting value as yet, can utilize a fixing electric current current potential that rechargeable battery is charged.When the voltage of rechargeable battery reaches this voltage setting value, then can change and utilize a fixing voltage potential that rechargeable battery is charged.Along with the capacity rising of rechargeable battery, the electric current current potential that offers rechargeable battery can reduce thereupon.When the electric current that receives when rechargeable battery reaches a current setting value, then stop to provide this voltage potential to give rechargeable battery.
Then, judge whether rechargeable battery connects charger (step S130) once more.If when rechargeable battery does not connect charger as yet once more, then continue execution in step S130.If when rechargeable battery connects charger once more, then measure a use value of rechargeable battery, and provide one first adjustment rechargeable electrical energy current potential to give rechargeable battery, in order to carry out one second charging procedure (step S140).The resulting use value of step S140 can be, and that carries out the time of this first charging procedure, the dump energy of rechargeable battery (remaining capacity), rechargeable battery opens the loop voltage (OCV) or the internal resistance of rechargeable battery.
In a possibility embodiment, the first adjustment rechargeable electrical energy current potential is relevant with this use value.For example, according to the use value that is obtained, the predetermined rechargeable electrical energy current potential that is provided when dynamically adjusting first charging procedure.Adjusted result is the first adjustment rechargeable electrical energy current potential that second charging procedure is provided.
Suppose that after finishing first charging procedure, rechargeable battery has one first charging capacity current potential (capacity level); After finishing second charging procedure, rechargeable battery has one second charging capacity current potential.When the use value of rechargeable battery during less than one first preset value, can adjust the rechargeable electrical energy current potential by first, make the second charging capacity current potential greater than the first charging capacity current potential.When use value during greater than one second preset value, adjust the rechargeable electrical energy current potential by first, make the second charging capacity current potential less than the first charging capacity current potential, wherein the second charging capacity current potential needs greater than a lower limit charging potential.In this example, first preset value can equal second preset value.
In addition, in first and second charging procedure, be not the lasting action that rechargeable battery is charged.With first charging procedure is example, when carrying out first charging procedure, only between a first phase, just rechargeable battery is charged; And in a second phase, stop rechargeable battery being charged.For example, because rechargeable battery is only when receiving predetermined rechargeable electrical energy current potential, the just action that can charge.Therefore, provide predetermined rechargeable electrical energy current potential give rechargeable battery during can be described as between this first phase.Stopping to provide after predetermined rechargeable electrical energy current potential gives rechargeable battery, and before rechargeable battery breaks away from charger during can be described as this second phase of first charging procedure.Time sum total during first and second is the duration of first charging procedure.Similarly, in second charging procedure, also non-continuing charged to rechargeable battery.When carrying out second charging procedure, only between a third phase, just rechargeable battery is charged; And between a fourth phase, stop rechargeable battery being charged.
One may embodiment in, can be by detecting the duration of first charging procedure, and obtain the use value of rechargeable battery, and according to the use value that is obtained, adjust the duration between third phase of second charging procedure.For example, if use value (i.e. the duration of first charging procedure) is during greater than a preset value, then the duration between the third phase is greater than the duration between the first phase; If use value is during less than this preset value, then the duration between the third phase is less than the duration between the first phase.
In another may embodiment, can be according to the length of first or the second phase in first charging procedure, and obtain the use value of rechargeable battery.In this example, according to the use value that is obtained, the just length between the third phase of may command second charging procedure.For example, if when the second phase in first charging procedure, (promptly stop rechargeable battery charging, and rechargeable battery not breaking away from the time of charger) was greater than a preset value, it is longer that the expression rechargeable battery is stranded in time of charger.Therefore, can increase duration between third phase in second charging procedure.Because the duration between the third phase depends on that first adjusts the size of rechargeable electrical energy current potential, therefore, need provide first a less adjustment rechargeable electrical energy current potential, can elongate the duration between the third phase.When utilizing a less electric energy current potential that rechargeable battery is charged action, can increase the life-span of rechargeable battery.
In other embodiments, provide this predetermined rechargeable electrical energy current potential give this rechargeable battery during, move if rechargeable battery when breaking away from charger suddenly, will interrupt charging, make rechargeable battery can't be charged to a preset capacity.Therefore, before carrying out second charging procedure, detect earlier the time of rechargeable battery actual reception, and according to the result who detects, adjust the duration between third phase of second charging procedure to this predetermined rechargeable electrical energy current potential.For example, if the duration that rechargeable battery receives this predetermined rechargeable electrical energy current potential during less than a Preset Time value, then in second charging procedure, provides a bigger rechargeable electrical energy current potential, to dwindle the duration between the third phase, use rechargeable battery to store more electric energy.
In addition, except obtain a use value of rechargeable battery at step S140, also can before carrying out first charging procedure, detect rechargeable battery, to obtain a preceding value.Therefore, in another possibility embodiment, the first adjustment rechargeable electrical energy current potential that second charging procedure is provided is relevant with this use value and preceding value.In this example, the first adjustment rechargeable electrical energy current potential is determined by the weighted mean (weightingaverage) of this use value and this preceding value.
Weighted mean (K
N) account form following as show, but be not limited to this:
K
N＝(a*K
N-1+b*C
N)/(a+b)
Wherein, a, b are the arithmetic number constant; K
N-1Be preceding value; C
NBe use value.
In addition, in another possibility embodiment, can detect a triggering signal and whether be triggered.When this triggering signal is sent out, then provide a maximum charge electric energy current potential to give rechargeable battery, in order to carry out corresponding charging procedure.For example, before carrying out second charging procedure,, then this maximum charge electric energy current potential first is adjusted the rechargeable electrical energy current potential as this if this triggering signal is triggered.In other embodiments, when carrying out second charging procedure,, then provide first to adjust the rechargeable electrical energy current potential if triggering signal is not triggered.Yet if triggering signal is triggered, and first when adjusting the rechargeable electrical energy current potential less than an evoked potential, replaces first with this a maximum charge electric energy current potential or a bigger rechargeable electrical energy current potential and adjust the rechargeable electrical energy current potential.If triggering signal is triggered, and first when adjusting the rechargeable electrical energy current potential greater than this evoked potential, then still provides this first to adjust the rechargeable electrical energy current potential.
After finishing second charging procedure, when being connected in charger again,, also need provide the second adjustment rechargeable electrical energy current potential to give rechargeable battery, in order to carry out one the 3rd charging procedure except detecting a use value of rechargeable battery once more as if rechargeable battery.If before carrying out the 3rd charging procedure, this triggering signal when the number of times that is triggered reaches a preset times, then second is adjusted the rechargeable electrical energy current potential with this maximum charge electric energy current potential as this in a Preset Time.Yet, after finishing second charging procedure,, still provide this second adjustment rechargeable electrical energy current potential to give rechargeable battery if this triggering signal is not triggered.
Though when triggering signal is triggered, can provide a maximum charge electric energy current potential to give rechargeable battery.But when if the interior resistive of rechargeable battery itself is big, then excessive rechargeable electrical energy current potential will speed up the speed that rechargeable battery wears out.Therefore, in a possibility embodiment, can before each charging procedure, detect the internal resistance of rechargeable battery, and, dynamically adjust the current potential of maximum charge electric energy according to testing result.
Fig. 2 is the schematic diagram of batter-charghing system of the present invention.As shown in the figure, batter-charghing system 200 comprises, electric energy output unit 210, control unit 220 and measuring unit 230.When rechargeable battery connected electric energy output unit 210, control unit 220 triggered electric energy output unit 210, in order to rechargeable battery is carried out one first charging procedure.After finishing first charging procedure, the user may be taken out rechargeable battery by electric energy output unit 210.When rechargeable battery connects electric energy output unit 210 once more, a use value of measuring unit 230 acquisition rechargeable batteries.After the use value of rechargeable battery was captured, control unit 220 triggered electric energy output unit 210 once more, in order to rechargeable battery is carried out one second charging procedure.
In a possibility embodiment, after finishing first charging procedure, before the user took out rechargeable battery, control unit 220 stored the charging interval or the standby time of rechargeable batteries, in order to the use value as rechargeable battery.Therefore, when rechargeable battery connected electric energy output unit 210 once more, measuring unit 230 just can carry out second charging procedure to rechargeable battery according to previous stored value.
As shown in the figure, electric energy output unit 210 has a position 211.When rechargeable battery was seated in position 211, electric energy output unit 210 just can carry out charging procedure to rechargeable battery.Electric energy output unit 210 has the electric current of deciding (constant current) and decides two kinds of charge modes of voltage threshold currents, in order to an electric current current potential or a voltage potential to be provided.For example, in constant current mode, electric energy output unit 210 can go out the maximum current current potential.When the voltage of rechargeable battery reached a voltage setting value, then electric energy output unit 210 changed with constant voltage mode rechargeable battery is charged.Charging current can rise along with the voltage of rechargeable battery and descend gradually.When charging current during, then stop rechargeable battery being charged less than a current setting value.
In a possibility embodiment, when rechargeable battery connected electric energy output unit 210, control unit 220 provided one first charging signals.Electric energy output unit 210 provides a predetermined rechargeable electrical energy current potential to give rechargeable battery, in order to carry out first charging procedure according to this first charging signals.When rechargeable battery connected electric energy output unit 210 once more, control unit 220 provided one second charging signals.Electric energy output unit 210 provides one first adjustment rechargeable electrical energy current potential to give rechargeable battery, in order to carry out second charging procedure according to this second charging signals.
Because the charging signals that electric energy output unit 210 can be provided according to control unit 220 gives rechargeable battery and produce corresponding rechargeable electrical energy current potential.Therefore, by the control charging signals, just can and then control the charging capacity of rechargeable battery.For example, when the charging signals that receives when electric energy output unit 210 is 5V, then rechargeable battery is charged with maximum charge electric energy current potential (as 29.4V).At this moment, rechargeable battery can be charged to peak capacity 100%.When being 0V, then rechargeable battery is charged with a rechargeable electrical energy current potential (as 28.7V) as if the charging signals that receives when electric energy output unit 210.At this moment, rechargeable battery can be charged to 90%.
In addition, when carrying out first or second charging procedure, electric energy output unit 210 may not be to continue to provide this predetermined rechargeable electrical energy current potential or this first adjustment rechargeable electrical energy current potential to give rechargeable battery.With first charging procedure is example, and when carrying out first charging procedure, electric energy output unit 210 provided this predetermined rechargeable electrical energy current potential to give rechargeable battery, and in the second phase, stops to provide this predetermined rechargeable electrical energy current potential to give rechargeable battery between the first phase.Same, when carrying out second charging procedure, electric energy output unit 210 provided this first adjustment rechargeable electrical energy current potential to give rechargeable battery, and between the fourth phase, stops to provide this first adjustment rechargeable electrical energy current potential to give rechargeable battery between the third phase.
When rechargeable battery connected electric energy output unit 210 once more, measuring unit 230 can obtain a use value of rechargeable battery.In a possibility embodiment, control unit 220 can directly produce the rechargeable electrical energy current potential and give rechargeable battery according to this use value.In another possibility embodiment, control unit 220 can be exported corresponding charging signals according to this use value, makes electric energy output unit 210 that corresponding rechargeable electrical energy current potential is provided.
In addition, between the above-mentioned third phase (promptly in second charging procedure, provide this first adjust the rechargeable electrical energy current potential during) duration can be relevant with this use value.For example, when the use value time of first charging procedure (as carry out) during greater than a preset value, electric energy output unit 210 provides this first to adjust rechargeable electrical energy current potential and give the time of rechargeable battery greater than providing this predetermined rechargeable electrical energy current potential to give the time of this rechargeable battery.When use value during less than this preset value, then electric energy output unit 210 provides this first to adjust rechargeable electrical energy current potential and give the time of this rechargeable battery less than providing this predetermined rechargeable electrical energy current potential to give the time of this rechargeable battery.
One may embodiment in, control unit 220 can be according to the use value of rechargeable battery, adjusting should predetermined rechargeable electrical energy current potential, and adjusted result first adjusts rechargeable electrical energy current potential and provides and give rechargeable battery as this.In another may embodiment, control unit 220 can be adjusted this first charging signals according to the use value of rechargeable battery, and with adjusted result as this second charging signals.Therefore, electric energy output unit 210 just can be according to this second charging signals, first adjusts the rechargeable electrical energy current potential and produce this.
In addition, suppose that after finishing this first charging procedure, rechargeable battery has one first charging capacity current potential; After finishing this second charging procedure, the voltage of rechargeable battery has one second charging capacity current potential.When the use value of rechargeable battery during less than one first preset potential, second charging signals that electric energy output unit 210 just can be provided according to control unit 220, provide the first adjustment rechargeable electrical energy current potential to give rechargeable battery, make this second charging capacity current potential greater than this first charging capacity current potential.
Opposite, when use value during greater than one second preset potential, what electric energy output unit 210 was provided first adjusts the rechargeable electrical energy current potential and will make this second charging capacity current potential less than this first charging capacity current potential.Though this second charging capacity current potential is less than this first charging capacity current potential, this second charging capacity current potential is still greater than a lower limit charging potential.In addition, this first preset potential can equal this second preset potential.
Measuring unit 230 these measured use values can be, and carry out the total time, first or the duration of the second phase, the dump energy of rechargeable battery, the charging interval of driving loop voltage, rechargeable battery of rechargeable battery or the internal resistance of rechargeable battery of this first charging procedure.In the present embodiment, measuring unit 230 obtains a use value of rechargeable battery before second charging procedure carries out.In another possibility embodiment, measuring unit 230 more can detect rechargeable battery, to obtain a preceding value before first charging procedure carries out.Therefore, control unit 230 just can provide this second charging signals according to this preceding value and this use value.For example, control unit 230 can determine this second charging signals according to the weighted mean of this preceding value and this use value.
In order to make measuring unit 230 have the function of measuring use value, measuring unit 230 need have corresponding module.In the present embodiment, measuring unit 230 comprises voltage measurement module 231, dump energy estimating module 232, signal controlling module 233, charge and discharge monitoring module 234, but is not in order to limit the present invention.In other embodiments, can omit one or part of module of 230 li of measuring units, or add other module among measuring unit 230 according to the use value of the required measurement of reality.
Please refer to Fig. 2, electric energy output unit 210 more comprises a specific button 212.When specific button 212 was pressed, a triggering signal was triggered by meeting.When signal controlling module 233 detects this triggering signal and is triggered, just export a control signal, make the corresponding charging signals of control unit 220 outputs.At this moment, the charging signals that electric energy output unit 210 is just produced according to control unit 220, and a maximum charge electric energy current potential is provided or provides a bigger rechargeable electrical energy current potential to give rechargeable battery.
For example, when carrying out second charging procedure, or before carrying out, if when specific button 212 is pressed, then electric energy output unit 210 provides this maximum charge electric energy current potential, first to adjust the rechargeable electrical energy current potential as this.In another possibility embodiment, when being pressed as if specific button 212, the first adjustment rechargeable electrical energy current potential that electric energy output unit 210 is exported is greater than predetermined rechargeable electrical energy current potential.In other possibility embodiment, when carrying out second charging procedure, electric energy output unit 210 provides this first adjustment rechargeable electrical energy current potential to give rechargeable battery.At this moment, when being pressed as if specific button 212, then adjust the rechargeable electrical energy current potential according to first, whether decision need utilize another rechargeable electrical energy current potential to replace the first adjustment rechargeable electrical energy current potential.For example, when adjusting the rechargeable electrical energy current potential greater than a predetermined trigger current potential as if first, electric energy output unit 210 still continues to provide this first adjustment rechargeable electrical energy current potential.If first when adjusting the rechargeable electrical energy current potential less than this predetermined trigger current potential, electric energy output unit 210 changes into provides a new rechargeable electrical energy current potential to give rechargeable battery, and wherein this new rechargeable electrical energy current potential is greater than this first adjustment rechargeable electrical energy current potential.
The present invention does not limit the number of times of charging procedure.When rechargeable battery is connected with electric energy output unit 210, just can carry out a charging procedure to rechargeable battery.For example, after finishing this second charging procedure, when being connected to electric energy output unit 210 once more as if this rechargeable battery, then electric energy output unit 210 provides one second adjustment rechargeable electrical energy current potential to give this rechargeable battery, in order to carry out one the 3rd charging procedure.
Before carrying out this second charging procedure, if when the number of times that is pressed in a Preset Time of specific button 212 reaches a preset times, then control unit 220 is adjusted the rechargeable electrical energy current potential with this maximum charge electric energy current potential as this first and second.Rechargeable battery is adjusted the rechargeable electrical energy current potential according to this first and second again, carries out corresponding charging procedure.When specific button 212 was not pressed, control unit 220 provided corresponding charging signals or corresponding rechargeable electrical energy current potential is provided according to the use value of rechargeable battery, in order to rechargeable battery is carried out charging procedure.
