Abstract
The utility model discloses utilize the principle of depolarization, turn-off in the twinkling of an eye at the constant current source, discharge to being charged the battery heavy current in the twinkling of an eye through depolarization circuit, in time eliminate polarization reaction, make by the battery be in the best all the time by the charged state. The charger comprises a transformer 1, a rectifier 2, a constant current and voltage regulating switch 3, a pulse generator 4, a depolarization 5, a timing control 6 and the like.
Description
The utility model is a kind of family expenses cadmium nickel (zinc-manganese) quickly charging battery device.
Current, ickel-cadmium cell is in family and people's routine work, obtained in the life being extensive use of, therefore, being in great demand of ickel-cadmium cell charger.Yet the charger supporting with the family expenses ickel-cadmium cell all belongs to plain edition, and its charging interval is longer, needs at the soonest to be generally 7～12 hours more than 3 hours, and the time-consuming electricity that takes is extremely inconvenient.
These family expenses ickel-cadmium cell quick charger is exactly the quick charger a kind of small-sized, easy to carry that is developed at above-mentioned present situation, and it is applicable to the ickel-cadmium cell quick charge in family, news interview photoflash lamp, communication apparatus, part instrument, the instrument.
This fills device soon and is made of circuit such as transformer, rectifier, constant current and switch, pulse generator, depolarising and timing controlled, transformer and rectification circuit provide operating voltage and the charging principal voltage are provided for other circuit, constant-current circuit provides the constant current charge electric current to being recharged the pond, simultaneously, be again a charge switch, whether control its switch by the output signal of pulse generator.The pulse generator output signal is also controlled depolarization circuit, the depolarization circuit output be recharged that the pond is anodal to link to each other, the timing control circuit output is controlled charge switch, depolarization circuit and pulse-generator circuit respectively.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 block diagram
Fig. 2 electrical schematic diagram
The quick charger of present embodiment is by transformer 1, rectifier 2, constant current and switch 3, pulse generator 4, circuit such as depolarising 5 and timing controlled 6 constitute, the secondary output voltage of transformer B obtains after two groups of full-wave rectifications of D1～D4+V1 charging principal voltage and+the integrated package back work voltage of V2.
T1, D5, D6, R8 constitute constant-current source, finish the constant current charge to battery E1, E2.This constant-current source is again a charge switch simultaneously, and whether its switch is subjected to the control of pulse generator IC1.
T2 is a discharge switch, controlled by IC1, when T1 turn-offs, and the T2 conducting, to R9, transient large current discharge is finished unpolarizing through T2 for E1 and E2.
IC2 is a timer circuit, close K when IC212 pin stop over/breakdown to place+during the V2 high level, timer resets, simultaneously, the T3 saturation conduction, T1, T2 all end, when K places empty position, timer work, T3 ends, and charger enters normal operating conditions; When the IC2 timing then, the IC23 pin is kept high level and is made the T3 conducting, charger quits work.
The R10 that is connected between main charge power supply+V1 and T1 collector electrode and the anode is a trickle resistance, and the little electric current that still has several milliamperes after charger is shut down is to battery E1, E2 boost charge, and it is fuller to make battery absorb electric energy.
Battery E1, E2 are two batteries that are connected in series in the present embodiment, during charging, can have only E1 or have only E2;
The timer timing is 15 minutes in the present embodiment.
This quick charger utilize discharge resistance R9 and discharge switch T2 at constant-current source T1 shutdown moment to high-rate battery discharge, realize the unpolarizing in the charging process, make and be recharged the pond and be in the optimal charge state all the time, not only the charging interval was shortened to tens minutes by a few hours in past, and remedied that common charger does not have the undercharge that automatic detection device causes or the defective of the damage battery that causes of overcharging, prolonged battery life to a certain extent, compare with general charger, it is little to have volume, advantage in light weight, easy and simple to handle, that charge efficiency is high, to be a kind of wide market that has, dark novel quick charger popular to people.
Claims (1)
1, family expenses ickel-cadmium cell quick charger, it is characterized in that by transformer 1, rectifier 2, constant current and switch 3, pulse generator 4, circuit such as depolarising 5 and timing controlled 6 constitute, the operating voltage that transformer and rectification circuit provide charging principal voltage and other circuit to need, constant-current circuit provides the constant current charge electric current to being recharged the pond, simultaneously, it is again a charge switch, whether its switch is controlled by the output signal of pulse generator, the output signal of pulse generator is also controlled depolarization circuit, the depolarization circuit output be recharged that the pond is anodal to link to each other, the timing control circuit output is controlled charge switch respectively, depolarization circuit and pulse-generator circuit.
