Abstract
The invention discloses a method for charging a nano modified power-type zinc-nickel secondary battery and capable of reducing damage to the battery at an initial charging stage and a final charging stage. The method comprises a pre-charging stage, a constant current stage and a balancing stage, wherein at the pre-charging stage, the charging current is slowly increased at a speed of 15 to 20 amperes per hour from zero till the charging current reaches a set charging current at the constant current stage, and the electric quantity of the secondary battery reaches 5 to 10 percent; and at the later stage of constant current charging, after the electric quantity of the secondary battery reaches 90 percent, the charging enters the balancing stage, the charging current is gradually reduced at the speed of 15 to 20 amperes per hour till zero, and the charging is finished. The damage of high current to the nano modified power-type zinc-nickel secondary battery is reduced by increasing the pre-charging stage and the balancing stage so as to greatly prolong the service life of the nano modified power-type zinc-nickel secondary battery.
Description
Technical field
The present invention relates to a kind of charging method, refer more particularly to the charging method of nano modified power-type zinc-nickel secondary battery.
Background technology
When nano modified power-type zinc-nickel secondary battery is charged, usually directly adopt methods such as constant current, constant voltage to force nano modified power-type zinc-nickel secondary battery is charged, initial stage in charging does not have preliminary filling process slowly, there is not equilibrium process slowly in the latter stage of charging, this just makes nano modified power-type zinc-nickel secondary battery sustain damage in the initial stage and the latter stage of charging, has shortened useful life greatly.
Summary of the invention
Technical problem to be solved by this invention is: a kind of charging method that can reduce the charging initial stage and latter stage battery be caused the nano modified power-type zinc-nickel secondary battery of damage is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the charging method of nano modified power-type zinc-nickel secondary battery, and its step comprises: preliminary filling stage, constant-current phase and equilibrium stage three phases; In the preliminary filling stage, charging current is slowly increased by the speed of zero beginning according to 15～20 amperes/hour, reach the charging current of the constant-current phase of setting until charging current, at this moment, the electric weight of secondary cell reaches 5～10%, in the constant current charge later stage, when the electric weight of secondary cell reaches after 90%, enter equilibrium stage, charging current reduces gradually according to 15～20 amperes/hour speed, until being zero, charging finishes.
The invention has the beneficial effects as follows: the present invention is by increasing preliminary filling stage and equilibrium stage, reduce the damage that big electric current forced charge causes nano modified power-type zinc-nickel secondary battery, prolonged the useful life of nano modified power-type zinc-nickel secondary battery greatly.
