The most in use, all the maximum voltage of super capacitor can be set near its maximum use value, it is therefore desirable to super
Level electric capacity carries out Control of Voltage accurately.
When super capacitor is charged by charger, constant current is used directly to fill the mode with constant voltage floating charge, at super capacitor
When voltage is relatively low, use constant current large current charge, when the voltage of super capacitor is close to setting, use the mode of constant voltage floating charge instead,
The electric current that the present invention uses only detects voltage at constant-current charging phase, does not the most substantially have power attenuation.Electricity when super capacitor
When crimping nearly setting, by intelligent decision charge condition, then decide whether to need energy of releasing.Its concrete implementation process is such as
Under:
First resistance R1, the second resistance R2 and the 3rd resistance R3 connect end 102 to being connected to the first connection end 101 and second
The voltage of super capacitor carry out dividing potential drop, the voltage of super capacitor is sampled, the first of A point sampling obtained afterwards is adopted
High accuracy the first reference voltage that sample voltage and the first controllable accurate source of stable pressure U1 provide contrasts, when the voltage of super capacitor
When value exceedes setting, this first sampled voltage can be higher than the first reference voltage so that the first controllable accurate source of stable pressure U1 conducting,
Drag down B point voltage value so that the first audion Q1 conducting, and then make the first Darlington transistor Q2 conducting, by the 11st electricity

Simultaneously according to the maximum charging current of system, set maximum leakage current.
After releasing the overvoltage of super capacitor, the voltage of super capacitor, still above setting, illustrates this
Super capacitor or foregoing circuit there occurs overvoltage fault, now use warning circuit unit 50 output alarm signal, its process
It is: by the 13rd resistance R13, the 14th resistance R14, the 15th resistance R15 carries out dividing potential drop to this overvoltage, to super capacitor
Overvoltage sample, the second sampled voltage of C point sampling obtained afterwards and the second controllable accurate source of stable pressure U2 provide
High accuracy the second reference voltage contrast, when the magnitude of voltage of super capacitor exceedes setting, this second sampled voltage meeting
Higher than the second reference voltage, the second controllable accurate source of stable pressure U2 conducting, drag down D point voltage value so that the 3rd audion Q4 conducting,
And then making the second light emitting diode D1 luminous alarm, this alarm signal will connect end 501 and the 4th by the 3rd and connect end 502
Output.

The two-stage type balancing circuitry for super capacitor module that the present invention relates to can be to the electricity of each super capacitor
Pressure accurately measures；For the charging process of super capacitor, only when the voltage of super capacitor is close to setting, just can cause
Some energy losses, because when the voltage of super capacitor is close to setting, by intelligent decision charge condition, then deciding whether
Need energy of releasing, during releasing, moreover it is possible to dynamically adjust leakage current so that the energy consumption of overall plan compared to
Prior art is substantially reduced；For false alarm situation of the prior art, it may be assumed that as long as charging voltage reaches setting it is necessary to hold
OK: on the one hand start leadage circuit, send an overvoltage signal to system the most immediately, thus need artificial intervention,
See whether super capacitor is damaged or other failure condition, present invention employs warning circuit unit 50 so that release back
The enabling signal on road and external alarm signal separately, only when have occurred that release and super capacitor magnitude of voltage still
In the case of exceeding setting, just explanation strictly there occurs overvoltage fault, thus greatly reduces the probability of false alarm.Because
Just release sample circuit unit 10, contrast circuit of releasing unit 20, release on-off circuit unit 30 and leadage circuit unit 40
For, the probability that above-mentioned false alarm occurs is the highest, as long as substantially charging arrival will be reported to the police.
Which kind of mode no matter the two-stage type balancing circuitry that the present invention relates to, use, as long as by above-mentioned leadage circuit unit 40
Separately process with warning circuit unit 50, thus reach to prevent the purpose of false alarm, all belong to protection scope of the present invention.
