Abstract
The utility model relates to a charger and belongs to a chemical battery, which is suitable for charging for various batteries which can be charged and various dry batteries which can not be charged. The utility model is characterized in that a resistance R and a diode D are connected in series with the positive end of a battery E and the output ends of C and R voltage dividers; the reverse charging of the cell can be carried out by the negative half cycle of the alternating current with 220V which is carried out the voltage reduction by the C and R voltage dividers through the resistor connected in series and the diode, for eliminating the polarization phenomenon in the cell; the service life of the cell can be extended. The utility model has simple circuit structure, low cost, small size and convenient operation.
Description
The utility model relates to a kind of charger of novel two directions charging, belongs to chemical cell, is applicable to various chargeable batteries and can not fills dry cell and charge.
Existing charger all is the single direction charging, and battery generation because of polarization phenomena in the discharge use strengthens internal resistance, and energy reduces, and the existence because of polarization during charging is hindered charging, and all demutations of the active matter of electrode cause undercharge.
For overcoming above-mentioned shortcoming, the utility model provides a kind of New-type charge device that can eliminate the two directions charging of inside battery polarization (obstruction battery charge) phenomenon.
Fig. 1 is the electrical schematic diagram of existing charger, and Fig. 2 is an electrical schematic diagram of the present utility model.
By Fig. 1, the 220V alternating current is through divider C, R1Step-down is by diode D1After the halfwave rectifier battery E is charged, this is the charging of single direction.
Profile of the present utility model is a cuboid, and there is printed circuit board (PCB) housing the inside, one side circuit board electric elements of the present utility model are set, another side has the bracing frame of placing two kinds of need rechargeable batteries.
The utility model realizes by following technical measures, and promptly in charge circuit, series resistor R and diode D between the anode of battery E and C, R voltage divider output make the 220V alternating current through CR
1The voltage divider step-down, its negative half period carries out reverse charge through the resistance R and the diode D of serial connection to battery E, like this, can eliminate the polarization phenomena of inside battery, prolongs the useful life of battery.
In conjunction with Fig. 2 content of the present utility model and embodiment are described below:
On the basis of existing halfwave rectifier charger, between the anode of battery E and voltage divider output, be connected a resistance R
2And diode D
2, at diode D
1Negative pole, D
3Positive pole and the negative terminal of battery E between be connected with clamp circuit D
4D
SThe diode group, according to the big or small number of determining diode of the electromotive force of battery E, the effect of clamp circuit is to avoid battery E to overcharge.
The course of work: the 220V alternating current is through voltage divider C, R
1After the step-down, sinusoidal wave positive half cycle is through diode D
1Rectification is through D
3To battery E charging, sinusoidal wave negative half period is through diode D
2Rectification is through resistance R
2, to the reverse low current charge of battery E, diode group D
4D
SBe clamp circuit, can avoid battery E to overcharge.
The voltage divider that is connected with power supply is by capacitor C and resistance R
1Form, its output V meets diode D
1Positive pole, be connected in series a diode D again
3Be connected with the positive pole of battery E, the negative pole of battery E connects power supply, diode D
1Negative pole and diode D
4Positive pole connect D
4D
SBe one group of diode of polyphone, D
SNegative pole be connected with power supply.According to the size decision capacitor C of battery E electromotive force, resistance R
1, R
2Size.
The utility model is a kind of pulsation charging modes, promptly sinusoidal wave positive half cycle carries out large current charge to battery, sinusoidal wave negative half period carries out reverse low current charge to battery, to eliminate the polarization phenomena of inside battery, and can be to filling with common charger, but the waste battery with chargeable factor carries out restorative charging, this charger adopts positive half cycle large current charge, supply with the battery electric energy supplement, the little electric current of negative half period charges in the other direction and makes the electrode activity thing carry out chemical reaction, the demutation of intensifier electrode active material repeatedly.Battery life is prolonged, and low cost of manufacture, volume is little, and is easy to use.Through on probation, reached design effect fully.
