Abstract
The utility model relates to 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, reverse series diode (4) in DC loop, by charger (6) and the isolation of direct-flow storage battery group.The utility model has changed the pattern of original direct-flow storage battery group charging, adopt independently mode of cell batteries, each joint storage battery is carried out to specific aim charging, solved the unbalanced problem of battery tension that whole group of charging brings, greatly improved the useful life of storage battery, and the stability of not impact system operation.
Description
Technical field
The utility model belongs to direct-flow storage battery group applied technical field, relates in particular to a kind of specific aim direct-flow storage battery charging device, and 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, during normal operation, charger is powered to whole DC load, charger is simultaneously also for batteries is charged online, when 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, by practical application, find, because of batteries in support battery by charger, undertaken whole group always and carry out floating charge, along with the lengthening of storage battery running time and the variation of ambient temperature, the accumulator property that respectively saves 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, when 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 bother, 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 purpose of this utility model 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, by all administration modules of electric power source pair of module, carry out Power supply, 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, while is reverse series diode in DC loop, by charger and the isolation of direct-flow storage battery group, when normal operation, charger is powered to DC load, when charger fault or dead electricity, diode current flow, by batteries, DC load is powered, ensure the continuity of DC load power supply.
The utility model 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, changed 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, solved 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.
Accompanying drawing explanation:
Fig. 1 is system configuration schematic diagram of the present utility model.
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 accompanying drawing explanation and embodiment, the utility model is described in more 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, the unified power line 3 that passes through of each administration module 2 is connected with power module 1, by 1 pair of all administration module 2 of power module, carry out 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, while is reverse series diode 4 in DC loop, by charger 6 and the isolation of direct-flow storage battery group, when normal operation, charger 6 is powered to DC load 7, when charger 6 faults or dead electricity, diode 4 conductings, by batteries, DC load 7 is powered, ensure the continuity of DC load 7 power supplies.
Therefore, the utility model 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, changed original direct-flow storage battery group by whole group of mode of charging of charger, and adopt, cell batteries is carried out to by battery performance state, carry out specific aim independently disperse to charge, on the basis that does not affect original system mode operational reliability and stability, solved 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, reduced greatly the cost of investment of direct current system.
