Abstract
The invention relates to a specific direct-current storage battery charging device which comprises a power module (1), management modules (2) and storage batteries (5). The specific direct-current storage battery charging device is characterized in that the management modules (2) are directly connected to the two electrodes of the storage batteries (5) in parallel, all the management modules (2) are connected with the power module (1) through power lines (3) respectively, all the management modules (2) are powered by the power module (1), a diode (4) is reversely connected into a direct-current loop in series, and a charger (6) is isolated from a direct-current storage battery pack. According to the specific direct-current storage battery charging device, an original direct-current storage battery pack charging mode is changed, the mode that the single storage batteries are independent is adopted for specifically charging the storage batteries, the problem that the voltages of the storage batteries are not balanced when the whole storage battery pack is charged is solved, the service life of the storage batteries is greatly prolonged, and stability of system running is not affected.
Description
Technical field
The invention belongs to direct-flow storage battery group applied technical field, relate in particular to a kind of specific aim direct-flow storage battery charging device, it is mainly used in the industries such as electric power, communication, finance, mining industry, media, power supply.
Background technology
At present, in DC power system, storage battery is cascaded and forms back-up source and provide energy for whole power-supply system, when normal operation, charger is powered to whole DC load, charger is simultaneously also for batteries is charged online, in the time of charger fault or dead electricity, batteries can seamless switching be that DC load is powered, safeguards system is normally moved, and general batteries requires to support power supply in 2 hours, but, find by practical application, because of batteries in support battery undertaken whole group by charger always and carry out floating charge, along with the lengthening of storage battery running time and the variation of ambient temperature, each joint accumulator property in batteries changes, some accumulator internal resistance change causes greatly the float charge voltage at its two ends to uprise, and whole group of float charge voltage of charger is certain, so must cause the float charge voltage step-down of some storage battery, under this situation along with after the long-play of batteries, we find that the hydraulic performance decline of whole group storage battery is faster, in the course of time just there is huge potential safety hazard in storage battery, in the time that direct current system needs batteries to carry out supplying power for outside, discovery causes whole group storage battery group cannot externally export rated current because the hydraulic performance decline of a few batteries is too fast.Exist at present some technology specially the storage battery of batteries to be carried out to on-Line Voltage equilibrium, although but this technology has solved battery tension equalization problem, but portfolio effect is poor, or how effect needs outside universal instrument monitoring, comparatively trouble, cannot carry out specific aim Charge Management to storage battery, lack for storage battery provides best float charge voltage, ensure the useful life of storage battery.
Summary of the invention
The object of the present invention is to provide a kind of specific aim direct-flow storage battery charging device, solve in existing application technology whole group of batteries is charged to the inconsistent problem of cell batteries float charge voltage, increasing storage battery service life, realizing the technical scheme that object of the present invention takes is: a kind of specific aim direct-flow storage battery charging method, include power module, administration module and storage battery, it is characterized in that: administration module is directly attempted by storage battery the two poles of the earth, each administration module unification is connected with power module by power line, carry out Power supply by all administration modules of electric power source pair of module, administration module can gather the terminal voltage of storage battery, according to floating charge strategy, the storage battery of different performance state is carried out to specific aim and disperse distributing floating charge, reverse series diode in DC loop simultaneously, by charger and the isolation of direct-flow storage battery group, in the time of normal operation, charger is powered to DC load, in the time of charger fault or dead electricity, diode current flow, by batteries, DC load is powered, ensure the continuity of DC load power supply.
The present invention is in conjunction with on-the-spot application request, find the problem that traditional storage battery group exists and a kind of new thinking proposing, change the pattern of original direct-flow storage battery group charging, the mode that adopts cell batteries charge independence to disperse, each joint storage battery is carried out to specific aim charging, solve the unbalanced problem of battery tension that whole group of charging brings, the useful life of greatly having improved storage battery, and the stability of not impact system operation.

Fig. 1 is system configuration schematic diagram of the present invention.
In figure: 1, power module, 2, administration module, 3, power line, 4, diode, 5 storage batterys, 6, charger, 7, DC load.
Embodiment
Below in conjunction with brief description of the drawings and embodiment, the present invention will be further described in detail.Referring to accompanying drawing, a kind of specific aim direct-flow storage battery charging device, include power module 1, administration module 2 and storage battery 5, it is characterized in that: administration module 2 is directly attempted by storage battery 5 the two poles of the earth, each administration module 2 is unified to be connected with power module 1 by power line 3, by power module 1, all administration modules 2 are carried out to Power supply, administration module 2 can gather the terminal voltage of storage battery 5, according to floating charge strategy, the storage battery 5 of different performance state is carried out to specific aim and disperse distributing floating charge, reverse series diode 4 in DC loop simultaneously, by charger 6 and the isolation of direct-flow storage battery group, in the time of normal operation, charger 6 is powered to DC load 7, in the time of charger 6 faults or dead electricity, diode 4 conductings, by batteries, DC load 7 is powered, ensure the continuity that DC load 7 is powered.
Therefore, the present invention is in conjunction with on-the-spot application request, find the problem that traditional storage battery group exists and a kind of new thinking proposing, change original direct-flow storage battery group by whole group of mode of charging of charger, and adopt to cell batteries carry out by battery performance state carry out specific aim independently disperse charge, on the basis that does not affect original system mode operational reliability and stability, solve the unbalanced problem of battery tension that whole group of charging brings, the useful life that directly extends storage battery is nearly more than 2 years, reduce greatly the cost of investment of direct current system.
