Abstract
The invention discloses a method for charging a lead-acid storage battery able to shorten charging time and making charge current safe and comfortable, dividing the whole charging course into at least three charging stages, each of which charges the lead-acid storage battery in turn in constant current and voltage modes. And the method is mainly used to charge lead-acid storage batteries.
Description
Technical field
The present invention relates to a kind of charging method of lead acid accumulator.
Background technology
At present, the constant voltage and current limiting method is the most frequently used a kind of in all lead acid battery charge modes.So-called constant voltage and current limiting method is actually constant voltage charge and constant current charge is combined, so be called the mixed charged method again.In the charging incipient stage, because the voltage of storage battery is relative low excessively, excessive and damage battery for fear of charging current, so adopt the constant current charge method to limit charging current, but generally speaking, this charging current is still bigger, and this helps the even compactness of positive active material and interfacial structure, improves the capacity and the cycle life of accumulator plate; With constantly carrying out of charging, the voltage of storage battery constantly raises, and when the voltage of storage battery reaches predetermined value, just switches to constant voltage charging method from the constant current charge mode storage battery is charged.The shortcoming of this charging method is: this above-mentioned predetermined value is no matter how selected, all can't be in harmonious proportion this a pair of contradiction of charging interval and charging current.If this predetermined value is fixed high, the charging interval can shorten, and still, charging current will be excessive, can produce a large amount of heat and gas and separate out in charging process, consumes a large amount of electrolyte; If this predetermined value is fixed low, though can make charging current safety moderate, the charging interval will become very long.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and not only can shorten the charging interval, but also can make the charging method of the moderate lead acid accumulator of charging current safety.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of charging method of lead acid accumulator, whole charging process comprises at least three charging stages that are connected mutually, and each charging stage charges to lead acid accumulator with constant current and constant voltage mode again successively.
In at least three above-mentioned charging stages that are connected mutually, the charging current of current constant mode reduces successively, and the charging voltage of constant voltage mode raises successively.
Whole charging process comprises three charging stages that are connected mutually.
Before three above-mentioned charging stages that are connected mutually, also comprise a pre-charging stage.
Beneficial effect of the present invention is: adopt substep constant voltage, constant current charge, can avoid producing a large amount of heats and gas is separated out, thereby control water electrolysis effectively, reduce the loss of electrolyte; Constant relatively charging end voltage, electric current is provided, shortened the time of charging greatly.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
The charging method of a kind of lead acid accumulator of the present invention is divided into three charging stages that are connected mutually with whole charging process, with constant current and constant voltage mode lead acid accumulator is charged successively again in each electricity stage.Charging voltage curve A from Fig. 1 and charging current curve B are as can be seen, in three charging stages that mutually are connected, the charging current of current constant mode reduces successively, from C/8 to C/16 again to C/32, the charging voltage of constant voltage mode raises successively, from 1.2U to 1.25U again to 1.31U.The detailed process of above-mentioned charging method is: as shown in Figure 1, before three charging stages that are connected mutually, also have a pre-charging stage 1, in this pre-charging stage 1, adopt the constant voltage suitable storage battery to be carried out the precharge of certain hour with the rated voltage U of storage battery; Enter the phase I 2 that constitutes by constant current charge 21 and constant voltage charge 22 then, in this stage, at first storage battery is charged with the constant current about C/8, when the voltage of storage battery rises to 1.2 times of rated voltage U and is 1.2U, then use this value of 1.2U instead storage battery is carried out constant voltage charge, along with constantly carrying out of charging, charging current constantly reduces, when charging current is decreased to C/16, then enter the second stage 3 that constitutes by constant current charge 31 and constant voltage charge 32, in this stage, at first storage battery is carried out constant current charge with this value of C/16, when the voltage of storage battery rises to 1.25 times of rated voltage U and is 1.25U, then use this value of 1.25U instead storage battery is carried out constant voltage charge, along with constantly carrying out of charging, charging current constantly reduces, when charging current is decreased to C/32, then enter the phase III 4 that constitutes by constant current charge 41 and constant voltage charge 42, in this stage, at first storage battery is carried out constant current charge with this value of C/32, when the voltage of storage battery rises to 1.31 times of rated voltage U and is 1.31U, then use this value of 1.31U instead storage battery is carried out constant voltage charge, along with constantly carrying out of charging, charging current constantly reduces, when charging current was decreased to C/64, whole charging process finished.
The advantage of the present invention in having kept the constant voltage and current limiting method, that is: also adopted bigger charging current that storage battery is charged in the constant current charge 21 in the phase I 2 of charging, guarantee the even compactness of positive active material and interfacial structure, improved the capacity and the cycle life of accumulator plate; Simultaneously, substep constant voltage of the present invention, current constant mode can avoid producing a large amount of heats and gas is separated out, thereby control water electrolysis effectively, reduce the loss of electrolyte; In addition, the phase III 4 provides constant relatively charging to finish electric current C/32 and charging end voltage 1.31U, has shortened the time of charging greatly.
