Description
Technical field
The present invention relates to power technique fields, relate in particular to a kind of replacing method of behindhand battery.
Background technology
In the communications industry, the stand-by power supply of DC power system mainly adopts lead-acid batteries, in batteriesIf the cell that capacity is lower is called behindhand battery, because batteries need to ensure to reach certain puttingThe electricity time, if there is behindhand battery in batteries, batteries in the time not reaching certain discharge time,The capacity of possible behindhand battery is used up, and now the duty of behindhand battery can change, if heldBattery pack works on, and may cause damage to other batteries of connecting with behindhand battery, therefore needs holdingBehindhand battery in battery pack is changed in time. But, lack at present behindhand battery decision method effectively, pastToward do not change in time behindhand battery because the judgement of behindhand battery is inaccurate, whole batteries is damagedBad, thus have influence on whole electric power system safety.
Summary of the invention
The invention provides a kind of replacing method of behindhand battery, can effectively judge behindhand battery,Thereby change in time behindhand battery, guarantee whole electric power system safety.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of replacing method of behindhand battery is provided, for the 48V batteries being formed by 24 cells,Comprise:
Detect the capacity C of each cell, and obtain the average size of cell in described batteriesA；
For each cell, judgementWhether >=7%, if so, belong to behindhand battery, if not,Do not belong to behindhand battery;
Removable parts or all behindhand battery.
Particularly, described removable parts or whole behindhand battery comprise:
In the time of number≤4 of 1 < behindhand battery, described batteries is discharged, when minimum capacity batteryVoltage drop during to 1.8V, detect the monomer voltage of behindhand battery, change monomer voltage≤1.87V's whereinBehindhand battery;
In the time of number=1 of behindhand battery, minimum capacity battery is behindhand battery, and inferior small-capacity cells does not belong toBehindhand battery, ifBe greater than 3%, change behindhand battery.
The replacing method of behindhand battery provided by the invention, by average size and the cell of batteriesThe percentage of the difference of capacity recently determines whether behindhand battery, thereby can enter behindhand battery timely and effectivelyRow is changed, and guarantees whole electric power system safety.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will be to implementingIn example or description of the Prior Art, the accompanying drawing of required use is briefly described, and apparently, the following describesIn accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not payingGo out under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the flow chart of the replacing method of a kind of behindhand battery in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearlyChu, intactly description, obviously, described embodiment is only the present invention's part embodiment, instead ofWhole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not making creationThe every other embodiment obtaining under property work prerequisite, belongs to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of replacing method of behindhand battery, for by 24 listsThe 48V batteries of body battery composition, comprising:
Step 101, detect the capacity C of each cell, and obtain the flat of cell in this batteriesAll capacity A;
Step 102, for each cell, judgementWhether >=7%, if so, belong to and fall behind electricityPond, if not, does not belong to behindhand battery;
Step 103, removable parts or whole behindhand battery.
The replacing method of behindhand battery in the present embodiment, holds by average size and the cell of batteriesThe percentage of the difference of amount recently determines whether behindhand battery, thereby can carry out behindhand battery timely and effectivelyChange, guarantee whole electric power system safety.
Particularly, above-mentioned steps 103, removable parts or whole behindhand battery comprise:
In the time of number≤4 of 1 < behindhand battery, above-mentioned batteries is discharged, when minimum capacity batteryVoltage drop during to 1.8V, detect the monomer voltage of behindhand battery, change monomer voltage≤1.87V's whereinBehindhand battery;
In the time of number=1 of behindhand battery, minimum capacity battery is behindhand battery, and inferior small-capacity cells does not belong toBehindhand battery, ifBe greater than 3%, change behindhand battery.
In this step, first need to consider the quantity of behindhand battery, if behindhand battery in batteriesQuantity is more, and replacing all behindhand batteries are wherein cumbersome, in some situation, it would be better directly by whole groupBattery is changed, therefore need to be according to the actual feelings of batteries in the time that the number of behindhand battery is greater than 4Condition, how the considerations such as such as service life are specifically changed; In the time of the negligible amounts of behindhand battery in batteries,The direct behindhand battery of changing is wherein comparatively economic way, therefore only electric for falling behind in this stepPond number is less than or equal at 4 o'clock and directly changes. In addition, simple according to the average size of batteries and monomer electricityThe behindhand battery that the percentage of the difference of tankage is judged might not can not use completely, in the communications industry,When being discharged to 1.8V, regulation cell stops electric discharge, according to the discharge data analysis to a large amount of batteries,When cell is discharged to 1.8V termination from 1.87V, probably can emit 7% electric weight, therefore at batteryWhen group termination electric discharge, voltage is greater than the behindhand battery of 1.87V and still can in batteries, normally works one sectionTime, in the situation that batteries can ensure certain discharge time, these behindhand batteries can be temporarily notChange. In addition, in the time that the number of behindhand battery is 1, minimum capacity battery is behindhand battery, inferior littleWhen capacity battery does not belong to behindhand battery, now also need to consider to hold between behindhand battery and time small-capacity cellsAmount extent, if the capacity difference between this behindhand battery and time small-capacity cells is very little, if explanationWhen this behindhand battery electric discharge reaches final voltage 1.8V, inferior small-capacity cells has also approached final voltage 1.8V,Therefore can temporarily not change this behindhand battery.
It should be noted that, above-mentioned batteries can be in the power-supply system in communication bureau room.
The replacing method of behindhand battery in the present embodiment, holds by average size and the cell of batteriesThe percentage of difference of amount recently determines whether behindhand battery, and select according to the concrete condition of behindhand battery asWhat is changed, thereby can change behindhand battery timely and effectively, guarantees whole electric power system safety.
The above be only the specific embodiment of the present invention, but protection scope of the present invention is not limited toThis, any be familiar with those skilled in the art the present invention disclose technical scope in, can expect easilyChange or replace, within all should being encompassed in protection scope of the present invention. Therefore, protection scope of the present invention shouldProtection domain with described claim is as the criterion.
