Description
Technical Field
The invention relates to the technical field of storage batteries, in particular to a charging method of a valve-regulated lead-acid storage battery for traction.
Background
The conventional charging method adopted by the valve-regulated lead-acid storage battery for traction is constant-voltage current limiting, 2.4V/monomer is usually used, the current is limited to be charged until the current value is stable and unchanged, and the storage battery is considered to be fully charged.
Therefore, the existing charging method of the valve-regulated lead-acid storage battery for traction cannot ensure the service efficiency of traction equipment and prolong the service life of the storage battery at the same time.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a method for charging a valve-regulated lead-acid storage battery for traction, which can ensure the use efficiency of traction equipment and prolong the service life of the storage battery.
In order to achieve the purpose, the invention is realized by the following technical scheme: a charging method of a valve-regulated lead-acid storage battery for traction comprises the following steps:
in the first stage, a constant current value I is used1Charging the storage battery until the total voltage of the battery pack reaches U1The charging time of the first stage is t1Wherein I1=X·C5A,X∈[0.1,0.5],U1YV/monomer @30 ℃, Y ∈ [2.35, 2.45 ∈ [ ]];
In the second stage, constant voltage value U is used1Charging the storage battery until the current value reaches I2Second orderCharging time of a segment is t2Wherein, I2=Z·C5A,Z∈[0.01,0.05];
A third stage of constant current I2Charging the storage battery for t3。
Further, when t is1+t2And when the time is less than 15min, finishing the charging and not carrying out the third-stage charging.
Further, the total charging time t1+t2+t3<14h。
The invention has the beneficial effects that: the invention provides a charging method of a valve-regulated lead-acid storage battery for traction, which is used for respectively carrying out constant-current charging and constant-voltage charging on the storage battery in a first stage and a second stage. The two stages keep the traditional constant-voltage current-limiting charging mode and finish the recharging of most of the capacity of the valve-regulated lead-acid storage battery. The low-current constant-current charging in the third stage can make up the insufficient charging in the first two stages and reduce the sulfation of the storage battery, and the water loss of the storage battery is less under the condition that the total charging rate is basically kept consistent, so that the service life of the storage battery is prolonged. Therefore, the charging method of the valve-regulated lead-acid storage battery for traction can ensure the use efficiency of traction equipment and prolong the service life of the storage battery.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the attached drawings and the detailed implementation modes.
As shown in fig. 1 to 3, the present embodiment provides a method for charging a traction valve-regulated lead-acid battery, which divides the charging process of the battery into a first stage, a second stage and a third stage. The first stage and the third stage are constant current stages, and the second stage is a constant voltage stage. Specifically, the method comprises the following steps:
the first phase is at a constant current value I1And carrying out constant current charging on the storage battery. The accumulator is a battery pack composed of a plurality of single bodies, and the charging time t of the first stage1To U by total voltage of the battery1The standard is. Wherein, I1=X·C5A,X∈[0.1,0.5],U1YV/monomer @30 ℃, Y ∈ [2.35, 2.45 ∈ [ ]]C5 represents the 5-hour rated capacity of the battery, and @30 ℃ represents that the design temperature of the present embodiment is based on 30 ℃. When the total voltage U of the battery pack1And when the preset value is reached, charging the storage battery enters a second stage.
The second stage is at a constant voltage value U1Constant voltage charging is carried out on the storage battery, and the charging time of the second stage reaches I by the current value2The standard is. Wherein, I2=Z·C5A,Z∈[0.01,0.05]. The first stage and the second stage retain the traditional constant voltage current-limiting charging mode. Preferably, I in this embodiment is adopted1And I2The value range of the valve-regulated lead-acid battery can complete recharging of most of the capacity of the valve-regulated lead-acid battery with higher efficiency.
The third stage is at a constant current value I2Charging the storage battery for t3. In particular, the third phase is at a smaller current I2The storage battery is charged, so that the insufficient charging in the first two stages can be made up, the sulfation of the storage battery can be reduced, and the water loss of the storage battery is less under the condition that the total charging rate is basically kept consistent, so that the service life of the storage battery is prolonged.
In one embodiment, when t is1+t2And when the time is less than 15min, finishing the charging of the storage battery, and not performing the third-stage charging. Batteries with shorter sum of first and second stage charging times are typically of relatively sufficient capacity, and the skilled artisan has found that for such relatively sufficient capacity batteries, the first and second stages have been able to achieve full charge. If the charging of the third stage is continued, the charging of the third stage is mainly a side reaction of the electrolyzed waterThis not only increases the charging time, but also leads to excessive water loss in the battery. Therefore, it is preferable that when t is1+t2And when the time is less than 15min, the storage battery finishes charging, and the third-stage charging is not carried out any more, so that the problem of overcharge and water loss of the storage battery with more sufficient capacity can be avoided.
In one embodiment, the total charging time t1+t2+t3And (5) less than 14h, technicians find that the storage battery basically achieves a better charging effect after being charged for 14 h. Therefore, the total charging time is not more than 14h, the charging effect of the storage battery can be ensured, and the charging time can be better saved.
As can be seen from the experimental data of fig. 2 and 3, the total charging time is saved by about 35% to 53% by using the charging method of the present application, and the total charging rate is substantially kept consistent.
While there have been shown and described what are at present considered the fundamental principles and essential features of the invention and its advantages, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
