The present invention relates to a regeneration device by the internal resistance of the battery, and in detail, while measuring the internal resistance of the battery by varying the level of the surge pulse voltage that changes the DC voltage supplied during charging according to the resistance value to the terminal The present invention relates to a battery and an internal resistance regeneration device capable of reducing the performance of a battery while effectively removing oxidized and adhered foreign matter.

In general, a battery is composed of a positive and negative electrode plate and an electrolytic solution, and can be used as a power source by generating direct current electromotive force by chemical reaction. The state of changing chemical energy into electrical energy is called discharge. In addition, it is well known that the state of charging and supplying electrical energy from an external power source to be converted into chemical energy is accumulated.

The battery which is repeatedly charged and discharged is called a storage battery or a secondary battery, and is widely used as a battery for a vehicle, a household battery such as a shaver, a battery for a mobile phone, a battery for a laptop, and the like.

Among the above batteries, a battery having a high internal resistance is charged by a pulse charging method.

The pulse charging method charges the battery according to a clock pulse. The pulse charging method charges the battery when the pulse current power supply of the set level is higher than the duty set voltage voltage and the voltage of the battery is lower than the battery full charge voltage.

In order to charge at 50% duty in the conventional pulse charging method, the duty set voltage is about 3.53V when the pulse power supply is 5V peak, and the state of the current charged in the battery by the above operation is as follows.

That is, while charging the battery at a constant voltage, the current charged in the battery is gradually reduced by skipping pulses to compensate for and charge the internal resistance of the battery near the battery's full charge voltage.

However, this conventional technique has a disadvantage in that it takes a long time for the charging voltage of the battery to reach the buffer voltage as the battery is constantly charged with a current of up to 50% duty.

Accordingly, a patent application No. 1998-0042701 (pulse charging method battery charging circuit) dated October 13, 1998 was proposed to charge the battery by changing the duty of the on-period pulse charging in order to provoke the battery buffer voltage according to the battery voltage To make the time faster,

It consists of a charging unit, a switching unit, a full-wave rectifying unit, a switching driver and a switching drive control unit,

The charging unit to charge the input current,

The switching unit performs a switching operation to adjust the amount of current charged in the charging unit,

The full wave rectifying unit rectifies the input power to output the pulse power.

The switching driving unit compares the output of the propagation current unit with the comparison voltage and compares the voltage of the battery with the battery buffer voltage to vary the output signal according to the main comparison value.

The switching driving control unit inputs the voltage of the charging unit by level shifting the voltage of the battery to be the comparison voltage and outputting the voltage to the switching driving unit, and flows into the initial charging unit until the voltage of the charging unit becomes a buffer voltage. In order to decrease the current gradually increasing linearly from the maximum value, the voltage of the charging unit is level shifted to become the comparison setting voltage of the switching unit so that the charging current of the battery is gradually reduced from the maximum value to the battery buffer voltage. It was done in a short time.

However, in the conventional pulse charging method of the battery charging circuit as described above, when the charging voltage is applied to the battery, the voltage can be applied in the form of pulse wave to speed up the charging, but the battery is repeatedly charged and discharged continuously. It is not possible to remove the foreign matter attached to the electrode plate of the oxidized, the foreign matter is to increase the internal resistance to greatly reduce the efficiency of the battery, so there was a problem that the battery is aged and can not be used for a long time.

Accordingly, Patent Registration No. 338897 (Life Extension Device for Efficient Use of Battery) was proposed.

The life extension device connected to the battery is composed of a state monitoring unit and the pulse generating unit of the remaining configuration except the state monitoring unit,

The state monitoring unit detects when a voltage higher than the battery's holding voltage is applied between the first and second power terminals (+,-) of the battery and generates a driving signal. A voltage detector for detecting a voltage between power supply terminals and a drive switch for operating when the output voltage of the voltage detector is higher than or equal to a predetermined level by the battery holding voltage are output.

The voltage detector includes a diode connected in a forward direction to the first power supply terminal, a resistor connected to one end of the diode, and a variable resistor connected between the other end of the resistor and ground.

The drive switch includes a transistor having a base connected to the variable resistor, an emitter grounded, and a drive signal supplied to a collector.

An oscillator for generating a clock signal oscillating at a predetermined frequency in response to the driving signal to generate a DC pulse in response to a driving signal of the state monitoring unit to supply the first power terminal of the battery; A direct current coupled to a switch for performing a switching operation in response to a clock signal of the oscillator, and generated between the first power supply terminal and an output terminal of the switch and generating the direct current pulse by the counter electromotive force generated in the switching operation of the switch. It consisted of a pulse generator.

The oscillator comprises an oscillating integrated circuit " 4584 " generating a frequency of 10.1 kHz, the switch comprising a transistor having an emitter grounded, a base connected to the output of the oscillator and a collector connected to the DC pulse generator. It was.

The DC pulse generator includes a diode connected in a reverse direction between the first power terminal and the output terminal of the switch, a resistor connected at one end to the cathode of the diode, a capacitor connected between the other end of the resistor and ground, and the resistor. It consists of an inductor coil connected between the other end of and the output end of the switch.

The lifespan extension device for efficient use of the conventional battery constructed as described above outputs a DC voltage of 13.2 to 13.8 volts which is converted from an AC voltage from a generator, which is a generator.

The state monitoring unit detects that the voltage applied between the first and second power terminals (+,-) of the battery is 13.2 volts or more, and generates a driving signal. As the transistor is turned on, current flows to its collector-emitter. The oscillator in the pulse generator was turned on to perform the oscillation operation.

As a result, " high " was applied to the base of the switch-in transistor at a period of about 10 kilohertz, and the switching operation of turn on and off was alternately performed.

As a result, a counter electromotive force was generated in the coil in the DC pulse generator and supplied to the first power terminal (+) of the battery as a DC pulse.

Therefore, the square wave pulse of about 13.2 volts or more is continuously supplied to the positive electrode plate through the positive electrode of the battery as tens of kilohertz, and the square wave pulse is about 2 A current, so the crystallized sulfate accumulated in the positive electrode of the battery is reactivated to activate the active sulfur molecule. This was to return to the electrolyte which is a battery solution.

However, the life extension device for efficient use of the conventional battery as described above has the disadvantage that the above-mentioned DC pulse is continuously applied while power generation by the generator is started due to the start of a passenger car. Of course, since a high current of 2A flows through the transistor which is the switch, heat is generated while the transistor repeatedly performs on / off. In addition, the transistor has to be overheated and damaged due to continuous operation in a state where a passenger car is started.

In addition, since the transistor, which is the switch, is damaged due to overheating and cannot be recognized even when it is always on, there is a problem such that the DC pulse is continuously supplied even in a state in which the start is not started, rather than a cycle caused by the oscillator.

Therefore, the present invention was devised to solve the above-described problems, and by measuring the internal resistance of the battery, the level of the surge pulse voltage which changed the DC voltage supplied during charging according to the resistance value was changed. It is an object of the present invention to provide a regeneration device by the internal resistance of a battery capable of reducing the performance of the battery while effectively removing foreign matters that have been oxidized and attached thereto.
