Abstract
The invention provides a constant-current charger. The constant-current charger is characterized in that a reactance is used for restricting a charging current for reducing the power consumption of a component which is used for limiting the current; wherein an inductor or a capacitor is used.
Description
Technical field
Patent constant current charger of the present invention, relates to a kind of manufacture field of industrial electrical equipment.
Background technology
To charge charger used usually to the battery of automobile accumulator jar and electric motor car, it is a kind of charger of constant pressure type, its charging voltage exported, often be limited at by about 1.2 of the nominal voltage of rechargable battery times, along with the rising of the terminal voltage of battery in charging process, pressure reduction between the terminal voltage of charger and the terminal voltage of battery, As time goes on and gradually reduce, and the design of this charger is, when charging current is little arrive to a certain degree after, just electricity is nipped off, so that ensure can not overcharge.
But, this charging modes, has the shortcoming that serious, is exactly, not thorough owing to charging at every turn, to cause on Plante-type plate take off attached lead sulfate, can not fully molten getting back in sulfuric acid solution go, in the course of time, this part lead sulfate, will crystalline particle be transformed into, when charging current is not enough large, be just difficult to by lead sulfate more molten getting back in sulfuric acid solution go.
This situation, scholar's brainstrust, is called " cell degradation: (average charge and discharge about 800 times) its internal resistance must increase, that voltage of the now charger output of first wife; be just not enough to overcome group within aged used batteries, therefore just can not fill electricity and go usually all mistakenly.To processing the conventional methods of used batteries exactly " scrapping ".
It is reported that the charger that the whole world charges the phone scraps 50,000 tons every year.
Summary of the invention
A utility model " high-voltage charger " originally, (patent No. is: ZL200920004591.4) is exactly design to overcome this drawback, and it is in fact the charging method that have employed constant current formula.
Problem for convenience of description, existing for lead acid accumulator.In charging process, there is a constant electric current to fill in battery all the time, this guarantees the lead sulfate on Plante-type plate, can fully molten getting back in sulfuric acid solution go.But by practice over 4 years, finding that original scheme is desirable not to the utmost, because of the element of the Limited Current that it adopts, is that its energy consumption is larger with pure resistance.
Now adopt a kind of more advanced scheme---carry out Limited Current with reactance, because of induction reactance and capacitive reactance all not consumed powers.
Now with capacitor (C) for capacitive reactance, limiting charging current is example, (see Fig. 1)
The voltage that civil power is 220 volts, is inputted by (A) and (B) two ends in Fig. 1, the appearance (C) of a serial connection capacity suitable, then through full-wave bridge rectifier circuit (D), carries by the battery that charges.
Its economy and social effect are all divided huge, and this scheme can be save user and to defecate fund, and the battery scrapped can be made to come back to life, and that is, battery can have been reported never more from now on.Charger for mobile phone also can adopt this kind of scheme from now on, and its charger also can not have been scrapped again.
