Voltage substantially maintains an equal level, and is now adjusted rear A point voltages and is also reduced to 0.1V.The battery charger 104 exports stable
Two current versus cells are charged.
Charge for a period of time again after, if judging unit 102 judges that detecting unit 101 is detected 104 in battery charger
When middle battery electric quantity is higher than Second Threshold, judging unit 102 is to the base stage I1 output high level of the first triode Q1, to institute
State the output high level of the base stage 12 (corresponding to the 3rd Regulate signal) of the second triode Q2, now the first triode Q1 conductings, institute
The second triode Q2 conductings are stated, now B point voltages continue to decline, it is assumed that drop to 0.05V, then now A point voltages are electric more than B points
Pressure, therefore the output end output voltage reduction of the operational amplifier U, the electric current increase being now input in optocoupler Q3, now,
Pwm chip 40 reduces the sky ratio that the electric current of output to battery charger 104 is accounted for so that the battery charger 104
The charging current virtual value of output is reduced, and power output reduces.I.e. described battery charger 104 exports the 3rd electric current the (the 3rd
The electric currents of electric current ＜ second) battery is charged.Due under the charging current virtual value of the output of the battery charger 104
Drop so that A point voltages decline, is adjusted after being adjusted when rear A point voltages substantially maintain an equal level with B point voltages and is also reduced to 0.05V.
Now, flow into the electric current in optocoupler Q3 and generally remain stable, pwm chip 40 controls the battery charger 104 and exports
The 3rd stable current versus cell is charged.
It is understood that the current effective value of the output of the battery charger 104 is bigger, the charge rate of battery is got over
Hurry up.That is, battery charging rate of the battery charging rate of the first electric current more than the second electric current；The battery of the second electric current fills
Battery charging rate of the electric speed more than the 3rd electric current.
Optionally, adjustment unit 103 also include negative-feedback circuit, the negative-feedback circuit include the first electric capacity C1, second
