Unit 24 not with the situation such as the electric property coupling of the first communication unit 24, charge controller end control unit 23 will stop filling
Electricity.
Fig. 2 is refer to, Fig. 2 is the charging schematic diagram that electronic installation 30 operates in dynamic current charge mode.Transverse axis in Fig. 2
It is the time.First in time T0To time T1Period when, charge controller end control unit 23 can because charge be set as dynamic
Current charging mode, and make current output current IOIt is the pairs of maximum charging current values of electronic installation 30, battery unit 34 because defeated
Go out electric current IOAnd cause current voltage value VBIt is lasting to rise.In time T1When, because battery detecting unit 35 detects battery unit
34 current voltage value VBMagnitude of voltage threshold value V is reachedD, therefore electronics end control unit 32 can produce it is corresponding
Electronics end signal is interrogated with informing the end of charge controller 20 when charge controller end control unit 23 receives electronics end
Number and obtain battery unit 34 and charged to magnitude of voltage threshold value VDInformation when, charge controller end control unit 23 can according to this
Control electric current feedback control unit 21 reduces output current IO, such as Fig. 2 times T1To time T2It is shown, output current IOIt is less than
Pairs of maximum charging current values, current voltage value VBAgain according to output current IOAnd rise.In the time T of Fig. 22When, current voltage value
VBAgain achieve magnitude of voltage threshold value VD, therefore charge controller end control unit 23 repeats above-mentioned step again, persistently enters
Row output current IOAdjustment, until battery unit 34 is charged to load voltage value completely.
Fig. 3 is refer to, Fig. 3 is the charging schematic diagram that electronic installation 30 operates in constant-current charge pattern.Transverse axis is in Fig. 3
Time.First in time T0To time T1Period when, charge controller end control unit 23 can because charge be set as determining electric current
Charge mode, and make current output current IOIt is the pairs of maximum charging current values of electronic installation 30, battery unit 34 because output electricity
Stream IOAnd cause current voltage value VBIt is lasting to rise.In time T1When, because battery detecting unit 35 detects battery unit 34
Current voltage value VBMagnitude of voltage threshold value V is reachedD, therefore electronics end control unit 32 can produce corresponding electronics
Device end signal to inform charge controller end 20, when charge controller end control unit 23 receives electronics end signal simultaneously
Obtain battery unit 34 and charge to magnitude of voltage threshold value VDInformation when, charge controller end control unit 23 can be controlled according to this
Electric current feedback control unit 21 is stopping output current IO, such as Fig. 2 times T1To time T2It is shown.When battery detecting unit 35 is detectd
Battery unit 34 is measured because stopping charging and causing its magnitude of voltage from magnitude of voltage threshold value VDFall below magnitude of voltage threshold
Value VDWhen, electronics end control unit 32 can according to this produce corresponding electronics end signal and be sent to charge controller
30.When charge controller end control unit 23 receives this electronics end signal, can be obtained according to this electronics end signal
Know that electronic installation 30 needs to proceed to charge, therefore the control electric current feedback control unit 21 of charge controller end control unit 23
Power circuit 10 is set to continue to output the output current I of pairs of maximum charging current valuesOBattery unit 34 is charged, such as Fig. 3 times T2Arrive
T3It is shown.Charge controller end control unit 23 simultaneously continues in accordance with the above to output current IOIt is adjusted, until battery list
Unit 34 is charged to load voltage value completely.
According to the above, can more converge it is whole go out charge control system of the invention operation method.Fig. 4 is refer to, Fig. 4 is
The operation workflow embodiment schematic diagram at the end of charge controller 20, confirms electronic installation 30 in step 401 charge controller 20 first
Whether can be communicated with electronic installation 30 with the electric property coupling of charge controller 20, and charge controller 20, that is, first logical
Whether news unit 23 can communicate with the second communication unit 31.Then in step 403, charge controller 20 is according to the electricity for receiving
Sub-device end signal confirms the information such as the charging operations pattern and pairs of maximum charging current values of electronic installation 30, and confirmation is finished and carried out
Step 405, anti-returns to step 401.In step 405, charge controller 20 is according to the electronics end signal and electricity for receiving
The charging operations pattern of sub-device 30 switches output current IO.In step 407, charge controller 20 judges whether that end is filled
Electricity, when being judged as YES complete charge, when being judged as that otherwise returning step 405 continues to charge.
Fig. 5 is refer to, Fig. 5 is the operation workflow embodiment schematic diagram at the end of electronic installation 30, first in step 501, electronics
Device 30 judges whether to start to charge up program with the electric property coupling of charge controller 20 and after can communicating, and when being judged as YES, is walked
Rapid 503, it is anti-, carry out step 501.In step 503, electronic installation 30 is persistently received and confirmed by the current electricity of battery unit 34
Pressure value VB, in step 505, judge the current voltage value V of battery unit 34BWhether magnitude of voltage threshold value V is equal toDIf being judged as
It is to carry out step 507, proceeds to charge, and by current voltage value VBInformation transmission to charge controller 20, work as judgement
It is no, electronics end control unit 32 then closes second switch unit 509.Carry out after step 507 is performed and again step
505, persistently judge the current voltage value V of battery unit 34B。
It is comprehensive the above, due to this case charge control system can the electronic unit of feedback in time 34 charged state it is (current
Magnitude of voltage VB), and charge controller 20 is communicated back in the way of signal, therefore charge controller 20 can not receive circuit in signal
Influence and in the case of being lost, correct by signal and quickly charged to battery unit 34, charge control of the invention
System is more because of the charged state for accurately grasping battery unit 34, therefore security during more effective raising charging.Additionally,
Battery unit 34 charges to magnitude of voltage threshold value V by initial pairs of maximum charging current valuesDAfterwards, the present invention is reducing output current value
Or battery unit 34 is charged in the way of pairs of maximum charging current values intermittent charge, effectively reduce current versus cell cell life
Influence, not only can reach the mesh ground of quick charge, more can effectively safeguard battery unit life-time dilatation, promote commercial effect
Benefit.
