Embodiment
Below cooperate graphic and the present invention's preferred embodiment, further setting forth the present invention is to reach the technological means that predetermined goal of the invention is taked.
Please refer to shown in Figure 1ly, is a kind of control device of charging, and it includes a control module 10 and a charging circuit 20.
This control module 10 includes a signal converter 11, a CPU (central processing unit) 12 and a connector 13.
This signal converter 11 can be an analog/digital converter (Analog to Digit Converter), it has an input end and an output terminal, this input end can be electrically connected a mesuring battary 30, the voltage to be measured of being exported to receive mesuring battary 30, this signal converter 11 is by this output terminal output after the digital signal with voltage transitions to be measured.
This CPU (central processing unit) 12 is electrically connected the output terminal of this signal converter 11, to receive the digital signal of these signal converter 11 outputs.Have a trace routine in this CPU (central processing unit) 12, judge type and corresponding output one control signal of this mesuring battary 30 according to voltage to be measured, in this preferred embodiment, to judge that this mesuring battary 30 is rechargeable battery or non-rechargeable battery, if rechargeable battery, then export a charging control signal, if non-rechargeable battery is then exported one and stopped charging control signal.
This connector 13 can be universal I/O (General Purpose I/O, GPIO), is to be electrically connected this CPU (central processing unit) 12, and maybe this stops charging control signal in order to receive and externally to transmit this charging control signal.
This charging circuit 20 is electrically connected the connector 13 of this mesuring battary 30 and this control module 10, maybe this stops charging control signal to receive this charging control signal, if receive charging control signal, then export a charge power supply so that this mesuring battary 30 is charged, stop charging control signal if receive, then stop to export charge power supply and stop this mesuring battary 30 charging.
Please refer to process flow diagram shown in Figure 2, the testing process of this trace routine below is described in detail in detail.
Judge that whether voltage to be measured that a mesuring battary 30 exports is less than a rechargeable battery ceiling voltage (step 101); Wherein, because of the output voltage (such as 1.2V) of general rechargeable battery (such as Ni-MH battery) be relatively less than the output voltage (such as 1.5V) of non-rechargeable battery (such as alkaline battery), therefore with the output voltage of general rechargeable battery as this rechargeable battery ceiling voltage, be the judgment standard of non-rechargeable battery as this mesuring battary 30 of preliminary judgement, and this rechargeable battery ceiling voltage is available for users to select.
If this voltage to be measured, judges then that voltage to be measured is from the mesuring battary 30 of non-charging greater than this rechargeable battery ceiling voltage; If after judging the mesuring battary 30 of voltage to be measured from non-charging, then export one and stop charging control signal, make charging circuit 20 stop 30 chargings of this mesuring battary.
If this voltage to be measured, judges then that whether this voltage to be measured is less than the maximum voltage (step 102) that detects less than this rechargeable battery ceiling voltage; Wherein, this maximum detects voltage and refers to the critical voltage that general rechargeable battery must be recharged, and should be available for users to select by maximum detection voltage, the rechargeable battery of specified exportable 1.2V for example, it is 0.8V that the user can select maximum detection voltage, if therefore when rechargeable battery output is lower than the voltage of 0.8V, represent its electric weight not enough and must be recharged.
If this voltage to be measured detects voltage (being that voltage to be measured is greater than this maximum detection voltage and less than this rechargeable battery ceiling voltage) greater than this maximum, representing these mesuring battary 30 electric weight is near state of saturation, but when mesuring battary 30 is near state of saturation, be that to be not easy to judge mesuring battary 30 be chargeable or non-rechargeabel.Therefore the accuracy that detects in order to improve battery variety must continue to judge whether this voltage to be measured detects voltage less than this maximum, detects voltage until this mesuring battary 30 is discharged to voltage to be measured less than this maximum.
If this voltage to be measured less than this maximum detection voltage, represents the electric weight deficiency of mesuring battary 30 and must be recharged; And before to mesuring battary 30 charging, because the kind of mesuring battary 30 not yet is determined, therefore to before these mesuring battary 30 chargings, must judge first that this mesuring battary 30 is rechargeable battery (step 103).
Please refer to process flow diagram shown in Figure 3, judging whether this mesuring battary 30 is in rechargeable battery (step 103) step, the internal resistance of the general rechargeable battery of cause is relative internal resistance greater than general non-rechargeable battery, therefore the charging rate of rechargeable battery can be slower than non-rechargeable battery; Therefore, according to this characteristic, this CPU (central processing unit) 12 generally speed of rechargeable battery charging is benchmark, and makes a test duration and a target voltage (step 201) according to this reference system.
Making this test duration and target voltage (step 201) afterwards, is to make charging circuit 20 outputs one surcharge control signal (step 202), within a short time mesuring battary 30 being charged.
Judging whether voltage to be measured promote within this test duration reaches this target voltage (step 203); If wherein voltage to be measured reaches target voltage beyond this test duration, this CPU (central processing unit) 12 judges that this mesuring battary 30 is rechargeable battery; Otherwise, if voltage to be measured this test duration with interior this target voltage that reaches, charging rate is very fast because the internal resistance of mesuring battary 30 is little in representative, this CPU (central processing unit) 12 judges that voltage to be measured is from non-rechargeable battery.
If judging this voltage to be measured from non-rechargeable battery, then exports one and stops charging control signal.
Come self-charging battery if judge this voltage to be measured, export a charging control signal, after charging circuit 20 receives charging control signal, namely to these mesuring battary 30 chargings (step 104).
In sum, this CPU (central processing unit) 12 is before execution judges whether this mesuring battary 30 is the step of rechargeable battery (step 103), to judge tentatively first whether the voltage to be measured that mesuring battary 30 is exported drops in the voltage range of this maximum detection voltage and the formation of rechargeable battery ceiling voltage, if voltage to be measured is greater than aforesaid voltage range, expression mesuring battary 30 is non-rechargeable battery, and can tentatively get rid of non-rechargeable battery; If voltage to be measured falls within the aforesaid voltage range, the electric weight of expression mesuring battary 30 is in state of saturation and is not easy to judge the kind of mesuring battary 30, therefore CPU (central processing unit) 12 continues to judge whether voltage to be measured detects voltage less than this maximum, until discharging into, mesuring battary 30 is lower than the maximum judgement that voltage just carries out battery variety afterwards that detects, so, effectively promote the accuracy of judging battery variety, reduce the chance of erroneous judgement.
By pick-up unit provided by the invention and detection method, can detect mesuring battary is rechargeable battery or non-rechargeable battery, if rechargeable battery, can be to this mesuring battary charging, otherwise, if non-rechargeable battery then stops this mesuring battary charging, to avoid the to cause dangerous situation of battery leakage, blast etc. to occur.In addition, along with the rechargeable battery of various models is different, various rechargeable battery output voltage sizes are also not identical with charging rate, by the present invention, the user can be according to corresponding this rechargeable battery ceiling voltage, this maximum detection voltage adjusted of case, and should test duration and this target voltage, and whether the mesuring battary that can detect various models be rechargeable battery.
The above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, in the scope that does not break away from technical solution of the present invention, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
