Description
Technical field
The present invention relates generally to a kind of circuit that is used for to the battery constant charge, and relate in particular to a kind of like this circuit that is used to make the battery constant charge, what this circuit will provide converts double surge pulse voltage (doubled surge pulse voltage) to for the direct voltage of battery charge, and the battery lead plate that only will this double surge pulse voltage when carrying out battery charge offers battery, thereby oxidized and stick to and prevented the aging of battery when impurity on the battery lead plate is removed on battery lead plate, thus with battery recovery to it reset condition also thereby make this battery to use for a long time.
Background technology
Usually, battery is a kind of device of being made up of positive electrode plate, negative electrode plate and electrolyte and can be used as the power supply that produces direct current (DC) electromotive force by the chemical action battery.The operation that chemical energy changes into electric energy is known as discharge, and the operation that provides electric energy and this electric energy to be converted to the chemical energy that will store from external power source is known as charging, and these operations are well-known in the art.
Battery through aforesaid charging and discharge repeatable operation is called as storage battery (storage battery or secondary battery), and it is widely used as and is automobile, the battery that electrical equipment such as refrigerator, mobile phone, notebook computer etc. use.
In addition, the battery with high internal resistance charges in the pulse current charge mode.
Pulse current charge is that the response clock pulse is a kind of mode of battery charge, wherein typically when have the pulsating voltage of setting level greater than work setting voltage (duty set voltage) and cell voltage during less than the battery buffer voltagc battery be recharged.
In this traditional pulse current charge mode, be battery charge thereby the work setting voltage typically is set in about 3.53V duty cycle (duty cycle) with 50% when the peak value of pulsating voltage is 5V.Below the state that fills into the electric current in the battery by aforesaid operations is described.
Also promptly, when battery during with constant-potential charge pulse to jump with the internal resistance of balancing battery and with the voltage near the battery buffer voltagc be battery charge, thereby reduce the electric current that fills in the battery gradually.
Yet traditional pulse current charge mode is defective, because electric current is constantly filled in the battery up to buffer time with 50% duty cycle, need spend long time so the charging voltage of battery reaches buffer voltagc.
Therefore, the battery charger of use disclosed pulse current charge mode in Korean Patent Application No. 1998-0042701 (on October 13rd, 1998) is suggested to shorten the battery charge time by the duty cycle that changes the ON interval, wherein finish pulse current charge, thereby allow charging voltage to reach the battery buffer voltagc according to cell voltage.
This battery charger comprises a charhing unit, a switch unit, and a full-wave rectification unit, one switches driver element, and one switches driving control unit.
This charhing unit is loaded with input current, and switch unit is controlled at the magnitude of current that charges in the charhing unit by carrying out handover operation.The full-wave rectification unit is by carrying out input voltage full-wave rectification output ripple voltage.Switch driver element and when the output of full-wave rectification unit and comparative voltage are compared, the voltage and the battery buffer voltagc of battery are compared, thereby the end value that responds two comparisons changes the output signal of this switching driver element.
This switching driving control unit becomes comparative voltage with the cell voltage that battery voltage moves to allow this level to move, and this comparative voltage is outputed to this switching driver element.Also be, this switching driving control unit becomes the electric current that the input of the voltage of this charhing unit and level move to allow to flow into this charhing unit in zero-time into buffer voltagc from the little by little linear voltage that reduces up to this charhing unit of its maximum, sets comparative voltage thereby the voltage that allows the level of this charhing unit to move becomes the work of this switch unit.As a result, this switching driving control unit when the voltage of this charhing unit becomes the battery buffer voltagc, is finished the charging of battery in the charging current that reduces battery from maximum gradually in the short time.
The battery charger of traditional use pulse current charge mode can improve charging rate, because the voltage of impulse waveform is provided when providing charging voltage to battery, but traditional battery charger is defective, because oxidation and the impurity that is attached on the battery lead plate of battery can not be removed on the battery lead plate at battery in the charging and the process of discharge operation repeatedly, and therefore these impurity internal resistance of having improved battery, and reduced the efficient of battery widely, thereby make cell degradation shorten its life cycle.

To achieve these goals, the invention provides a kind of circuit that is used to make the battery constant charge, wherein driving voltage is from preventing that by one reverse voltage diode and the adjustment driving voltage diode from offering controller to the power line that battery provides at charging circuit.
Controller receives input voltage by divider resistance from power line, uses the charging voltage of input voltage identification current/voltage (current voltage) and battery.
The controller identification input voltage that comprises an analog/digital converter is a digital value, and output is used to show the output signal of input voltage.
