Technical field

The utility model relates to electronic equipments, is specifically related to the charge in batteries limiter.

Background technology

The design of battery charger roughly has two types in the market: 1, second order segmentation; Be first constant voltage charge, charging current rises with battery tension and reduces gradually, after the storage battery electric energy adds to a certain degree; The voltage of storage battery rises to the set point of charger; The red diode indicator light of charger extinguishes, and the green diode indicator light is lighted, and charger changes the tiny stream electric current floating charge of second stage automatically over to.2, three is stage, promptly first constant current charge, and then constant voltage charge changes tiny stream electric current floating charge again over to.To the tiny stream electric current floating charge of storage battery appropriate time, be further sufficient electric weight on the one hand, be reparation and maintenance on the other hand to storage battery, can prevent that storage battery from forming irreversible sulfation.Practical proof generally is advisable with 2-3 hour tiny stream electric current floating charge, can cause the lead-acid battery dehydration if overcharge for a long time, makes the grid heavy corrosion of its positive plate generate a kind of irreversible oxidation thing simultaneously, causes grid distortion, embrittlement, loses skeleton and electric action; Long-term undercharge then can make unreacted active material form the positive bulky grain lead sulfate of irreversible height (PbSO4) crystal grain, makes charge in batteries time lengthening even scraps too early; Therefore to overcharge of a battery or all positive plates of serious harm storage battery of owing to charge, shorten the useful life of storage battery.In the daily life, charging person thinks that the charger green light lights, and just thinks that storage battery is full of, and complete charge causes tiny stream electric current floating charge not carry out at once, and lead-acid battery is then owed to fill; Another common situation is because of the operating time relation, and returning from work evening just begins charging, and complete charge when go to work the next morning causes lead-acid battery to overcharge for a long time.So have many professional persons to propose: " lead-acid battery is not damaged, but fills bad ".

Summary of the invention

The utility model problem to be solved is to above-mentioned technical deficiency; How a kind of charge in batteries limiter is provided; This socket can carry out timing to charger final stage tiny stream electric current floating charge; After the floating charge of tiny stream electric current reached set point, regularly socket cut off the 220V AC power complete charge of battery charger automatically, and manual work is cut off the electricity supply again.

The technical problem that utility model proposed is to solve like this, constructs a kind of charge in batteries limiter, it is characterized in that: comprise ac power switch K1, electromagnetism unhook coil driver, timing circuit, DC power supply circuit four parts; Ac power switch K1 adopts the switch of charged magnetic uncoupling rigging; Electromagnetism unhook coil driver is made up of triode Q1, triode Q2, resistance R 1 and capacitor C 5; Timing circuit is made up of quartzy small alarm clock, plug P1, jack J1, resistance R 2 and the timing start-up control triode Q3 of band timing function; Dc power electric routing transformer T, bridge rectifier diode D3-D6, filter capacitor C1, filter capacitor C2 and three-terminal voltage-stabilizing ic chip 1 constitute; Attaching plug one end links to each other with the 220V electrical network, and the moving contact 1 of

K switch

1 and 2 ends are in parallel with timing socket CZ, and another road is connected with the elementary of transformer T; Electromagnetism unhook coil one end is connected with triode Q1 collector electrode, and the feeder ear of the other end and+12V is connected, and coil two ends and diode D2 are connected in parallel; The jack J1 that draws regularly the start-up control signal directly links to each other with the plug P1 that introduces timing start-up control signal; Resistance R 2 one ends link to each other with plug P1; Resistance R 2 other ends are connected with control triode Q3, and the collector electrode of control triode Q3 is connected with the base stage of adjustment pipe Q4.

The beneficial effect of the utility model is: the useful life that prolongs lead-acid battery; Practice thrift the spending of frequent change lead-acid battery; Exempt the hardship that the charger power supply is broken off in manual work everyday, slowing down to scrap the pollution of environment too early and economize on resources because of lead acid accumulator all has far-reaching social effect.
