Description
Technical field
The utility model belongs to electronic information technical field, relates to a kind of battery charging management, discharge management, sulphur removal repair function of harvesting in the storage battery comprehensive intelligent management equipment of one, is specifically related to that a kind of intelligent accummulator charges and discharge and online sulphur removal comprehensive monitor.
Background technology
Valve-control sealed lead acid battery with in light weight, take up an area of less, invertibity is good, voltage characteristic is steady, long service life, applied widely, safe and reliable, outstanding advantage such as maintenance workload is few, has replaced acid-proof at a distance from battery cruelly.But the battery capacity of valve-control sealed lead acid battery is difficult to test, and management of charging and discharging and environment for use are had relatively high expectations.For the rated capacity and normal useful life of maintaining valve control sealed lead acid battery, must implement correct operational mode and meticulous maintenance management to it.
At present, mainly valve-control sealed lead acid battery is carried out maintenance management from Charge Management, discharge management and through three aspects of capacity that ad hoc approach recovers the deterioration storage battery.
Charge in batteries administrative skill aspect; Generally adopt to have and all fill with the floating charge pattern, possess the charging device of constant current pressure limiting function, whole group storage battery unification is charged: the storage battery that at first discharge is finished through charge mode to fix time and constant current quickly supplements energy to battery; All filling the end back is that storage battery provides constant float charge voltage and very little floating current with the floating charge pattern, prevents that storage battery from descending because of the capacity that self discharge causes.Because batteries is in series by cell, the consistency quality of every joint cell is the principal element of decision accumulator property.Each internal resistance of single cell varies in size, and during with the charging of this charging device accumulators group, certainly will cause in the charging process every joint cell charging unbalanced, if things go on like this can make the consistency of cell continue to worsen, and finally causes battery capacity to descend.
When storage battery is in discharge condition; Detect the terminal voltage of batteries in real time through detector, when finding that the pressure drop of batteries end to predefined control threshold values, thinks that the energy content of battery exhausts; For preventing that battery over-discharge from causing decreased performance, cut off storage battery output with the protection battery.Because there are not linear relationship in performance and its terminal voltage of storage battery; But determine by the consistency of monomer whose battery; When detecting the discharge of management of battery, for the battery of high conformity, after accumulator voltage arrives the control threshold values with detector; Each cell still possesses certain discharge capability, causes storage battery energy to fail to make full use of; For the battery of consistency difference, during accumulator voltage no show control threshold values, there has been the partial monosomy energy content of battery to exhaust, be in over-discharge state, this state meeting major injury accumulator property causes the quick deterioration of battery capacity.
Usually adopt capacity online or off-line type battery capacity prosthetic appliance recovery deterioration storage battery; The deterioration batteries is applied dynamic pulse, and the mode through pulse and lead sulfate crystallization resonance " smashes " also " dissolving " big lead sulfate crystallization gradually; Make it to be dissolved in electrolyte; Become the granule lead sulfate, be reduced into active material, thereby recover the capacity of storage battery through common charging.This prosthetic appliance has good capacity restoration effect for dehydration and sulfuration storage battery; But because whether storage battery the deterioration naked eyes occur and can't observe; Can only appraise and decide the capacity of storage battery through test, be lower than 80% battery for capacity after being verified and just can handle.The battery capacity prosthetic appliance that uses does not at present all possess the function of volume test or on-line tracing and differentiation storage battery degradation, causes storage battery repair process work to waste time and energy.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is that a kind of intelligent accummulator charges and discharge and online sulphur removal comprehensive monitor, comprises the power supply unit that is connected successively, central control and computing unit and charging/sulphur removal mode selecting unit; Central authorities control and computing unit respectively with the data communication interface unit, go here and there and fill output control and data acquisition unit is connected with the discharge output control unit; Charging/sulphur removal mode selecting unit is respectively with string and fill output control and data acquisition unit and be connected with the sulphur removal output control unit; Power supply unit also respectively with data communication interface unit, charging/sulphur removal mode selecting unit, sulphur removal output control unit, go here and there and fill output control and data acquisition unit and be connected with the discharge output control unit.
The utility model comprehensive monitor compared with prior art, its technical advantage and good effect are:
1) mode of charged in parallel behind the first serial connection charge of employing can effectively guarantee the consistency of each cell batteries, neither owes to fill thereby guarantee to put in order Battery pack, fills only.
2) adopt the capacity management method, according to the true capacity of storage battery, the control of discharging can accurately find battery capacity to exhaust a little, avoids battery overdischarge that infringement or storage battery that storage battery causes are failed to make full use of.
3) through the accurate assurance to the storage battery actual capacity, in time find the storage battery degradation, the very first time starts sulphur removal automatically and repairs pattern, and the deterioration storage battery is in time handled, and has guaranteed the power supply capacity and the useful life of storage battery.
4) with the Charge Management of storage battery, discharge management and integrate integrated to the sulphur removal repair process technology of deterioration storage battery; Greatly reduce battery service workload and maintenance difficulties; Make battery service more scientific and intelligent, effectively improved the maintenance management level of storage battery.
