Abstract
* The invention relates to battery pack equalizing equipment, which comprises storage batteries and is characterized by further comprising a processing device, a relay switching circuit, a charging circuit, a discharging circuit and a current adjusting circuit, wherein the charging circuit and the discharging circuit are connected with the storage batteries respectively and are connected with the processing device through the relay switching circuit; and the processing device is further connected with an RS485 communicating circuit and the current adjusting circuit. The internal resistance and the voltage of the single storage battery are measured through the processing device so as to charge and discharge the single battery in an equalizing manner, which is equivalent to that a small charger and a discharger are added to the single storage battery to automatically adjust and control all single batteries in a storage battery pack in an online equalizing mode; and the voltage and the volume at the end of each storage battery is equalized to avoid overvoltage charging and undervoltage charging for the single batteries, thereby charging and online activating the batteries with poor performance.
Description
Technical field
The present invention relates to a kind of battery equalizing equipment.
Background technology
Weighing the good and bad most important index of accumulator property is battery capacity, because the difference of storage battery manufacturing process, can not accomplish that every capacity in the storage battery long-time running can both reach consistent, be under the charger floating charge state on whole group of storage battery, because the performance difference of cell batteries, can be because accumulator super-charge or owe to fill and cause the batteries quick aging.Although the regular property checked discharge has certain effect to the activation storage battery, not can solve the aging problem of cell batteries.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: a kind of battery equalizing equipment is provided, can overcomes defects, can carry out automatic equalization, increasing storage battery service life to the storage battery of transformer station direct current system.
The technical solution adopted for the present invention to solve the technical problems is: described battery equalizing equipment, comprise storage battery, it is characterized in that: also comprise processing unit, relay switch circuit, charging circuit, discharge circuit and current regulating circuit, charging circuit and discharge circuit connect respectively storage battery, charging circuit is connected the relay switch circuit and connects processing unit with discharge circuit, processing unit also connects RS485 communicating circuit and current regulating circuit.
Processing unit is single-chip microcomputer and peripheral circuit thereof.Wherein charging circuit, discharge circuit, relay switch circuit and current regulating circuit are universal circuit.
The beneficial effect that the present invention has is: by processing unit the internal resistance of cell batteries, the measurement of voltage are realized cell batteries is carried out balance charge/discharge, can make the balancing performance of each batteries consistent, well play the purpose of activation storage battery, prolong the useful life of storage battery.This device is equivalent to add a small-sized charger and discharge instrument to cell batteries, automatically to the online balanced control of regulating of each cell in the batteries, allow every joint accumulator voltage, capacity be in equilibrium value, prevent the charging of cell over voltage, can replenish electricity and online activation to the weak battery of performance.
Description of drawings
Fig. 1 is frame principle figure of the present invention;
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
As shown in Figure 1, battery equalizing equipment, comprise storage battery, also comprise processing unit, relay switch circuit, charging circuit, discharge circuit and current regulating circuit, charging circuit and discharge circuit connect respectively storage battery, charging circuit is connected the relay switch circuit and connects processing unit with discharge circuit, processing unit also connects RS485 communicating circuit and current regulating circuit.
Processing unit is single-chip microcomputer and peripheral circuit thereof.Wherein charging circuit, discharge circuit, relay switch circuit and current regulating circuit are universal circuit.
Processing unit is started working after receiving balanced order by the RS485 communicating circuit, processing unit is judged and where is tied storage battery in the battery pack and need to carry out equilibrium, by relay switch circuit connection charging circuit and discharge circuit corresponding storage battery is carried out balance charge/discharge, processing unit making current regulating circuit guarantees accumulator cell charging and discharging safety simultaneously.
Wherein the single-chip microcomputer of processing unit is preferentially selected STC89C54RD+.
The effect of each circuit is as follows:
Relay switch circuit: by the relay switch circuit needs are carried out balanced storage battery and be linked in corresponding charging circuit or the discharge circuit.
Charging circuit: if battery tension is excessively low, need to charge, the storage battery that then will need to charge is linked in the charging circuit and charges.
Discharge circuit: if battery tension is too high, need to discharge, to keep the normal voltage of storage battery, the storage battery that then will need to discharge is linked in the discharge circuit and discharges.
Current regulating circuit: current regulating circuit intercoms mutually with processing unit, and in the storage battery balancing procedure, electric current is excessive when preventing accumulator cell charging and discharging, and during charging, along with cell voltage rises to normal working voltage, charging current weakens gradually; During discharge, along with cell voltage drops to normal working voltage, discharging current weakens gradually.
The RS485 communicating circuit: processing unit can carry out communication with host computer by the RS485 communicating circuit, receives the order from host computer, and to the host computer return data.
