Abstract
Disclosed is a simple nickel-cadmium battery charger. The charger comprises a simple circuit structure and a small number of electronic components. The charger has anti-counter-charging and anti-overcharge functions; by selecting a proper capacitor C1 in a resistance-capacitance voltage-reducing circuit, the charger can perform constant-current charging; and then the charger can stop charging automatically after full charge, so that the charger has the anti-overcharge function.
Description
Technical field
The present invention relates to a kind of charger of simple nickel separation cell.
Background technology
Nickel separation cell is many used in the live and work of people, is all have very for the charger to nickel separation cell
Polyelectron element and very complicated electronic circuit composition, because original paper is more, the fault rate of product is just high, uses very to user
It is inconvenient.
The content of the invention
A kind of charger of simple nickel separation cell of the present invention, from a small amount of electronic devices and components and simple electronic circuit group
Into, nickel separation cell can be charged, and charge be full of can also automatic stop function electricity.
A kind of charger of simple nickel separation cell, its circuit composition by capacitance-resistance voltage reduction circuit, rectification circuit filter circuit and
Charging circuit is constituted.
Description of the drawings
Fig. 1 is a kind of circuit theory diagrams of the charger of simple nickel separation cell.
Specific embodiment
As shown in drawings, R1, C1 composition capacitance-resistance voltage reduction circuit, reduces alternating current 220V voltage to give rectifier after some volts
B circuit rectifies, the direct current supply next stage circuit of output ripple is working power.
As shown in figure 1, C2 is filter circuit, the direct current of pulsation is become smoother direct current.S、R2、R3、R4、
D constitutes charging circuit, and S is the IC chip of model TL431, and charging current is determined by the electric capacity C1 in capacitance-resistance voltage reduction circuit, choosing
The value of electric capacity C1 when selecting conjunction, you can meet the charging current value needed for battery E.
The course of work of charger：When just charging, because battery E both end voltages are relatively low, the datum mark pressure side current potential of R3 is less than
Benchmark is pressed, the cut-off of integrated package R3 internal drives pipe, and its access is on whole charging circuit without impact.With the carrying out charged,
After battery sufficient voltage, when the current potential of R3 sliding ends reaches rated value about 2.5V, the conducting of integrated package R3 internal drives pipe, i.e. R3
By electric capacity C2 shorted on both ends, the charging current whole Jing R3 shuntings exported by C1, therefore battery E overcharges can be prevented.It is used to draw during D
Lead the reversely charging effect of charging current and isolation rechargeable battery.
Claims (1)
1. a kind of charger of simple nickel separation cell, it is characterised in that：Circuit composition is filtered by capacitance-resistance voltage reduction circuit, rectification circuit
Circuit and charging circuit are constituted；Capacitance in described capacitance-resistance voltage reduction circuit determines the straight of charging current, and this charger has
Anti-overcharge and counnter attack charge function.
