From several farads to tens thousand of farads, there is the highest power density, and charge/discharge rates is very fast, can be from entirely in several seconds
Discharge condition arrives fully charged state.
Owing to each monomer of super capacitor group is all different individuality, in production technology, the factor such as production time causes
There is difference in super capacitor performance index.Although along with the continuous progress of technology, the difference before dispatching from the factory, between super capacitor inside
Constantly reduce, but during using, faint discordance constantly can be amplified along with use condition.Such discordance
By increasing with design load deviation for the capacity that causes whole group of super capacitor.In charging process, the monomer that capacity is little will first
It is filled, causes the super capacitor of other capacity can not obtain enough capacity；In discharge process, the little monomer of capacity is first
Being discharged into blanking voltage, stopping is discharged by whole group of super capacitor.The existence of such problem of inconsistency, causes super capacitor
The active volume of group and the aspect such as service life far away from monomer super capacitor, and increase super capacitor is managed and
The difficulty controlled.Practice have shown that, significantly subtract when the consistency problem of super capacitor group develops into indivedual super capacitor generation capacity
Little, when internal resistance such as significantly improves at the situation, the performance of whole group of super capacitor can be at short time high progression, so that whole super electricity
Appearance group is scrapped.
In order to solve super capacitor group problem of inconsistency, there has been proposed the balancing technique of super capacitor.Balanced management
The voltage to the effect that detecting super capacitor group, the parameter such as electric current, these parameters are identified, analyze super capacitor
Concordance, discharges to the monomer of energy height by controlling device, makes the state of each monomer reach unanimity.By effectively
Balance route strategy and equalizing circuit can improve the consistency problem of super capacitor group, it is possible to extend the longevity of super capacitor group
Life, reduces the maintenance cost of super capacitor group, and the electric automobile making safe and efficient intelligence use puts it over.
The most general equalization methods is that each super capacitor is configured a discharge resistance, by checking each monomer
Voltage, is discharged by the discharge resistance of oneself correspondence to the monomer that monomer is higher.When super capacitor Capacity Ratio is bigger,
This discharge resistance discharge current would become hard to meet the requirement of fast uniform.If by discharge resistance merit corresponding for each super capacitor
Rate becomes big, and its volume and heat radiation are by the face of new challenge, and what the system of existing employing resistance equilibrium seldom had big current balance is
System.
