In general, a battery is a medium for storing electric energy, and stores electricity by using a charging device and supplies it to a load electric device. The battery mainly drives a power source of a moving electric device or a power source of an electric and electronic device, a car or a generator Or, it is used to supply power to electronic devices such as electric devices. In recent years, with the development of electricity and electronic technology, electronic devices using batteries increase and diversify, precision, high functionality, and advanced power supply are stable. With this demand, the importance of batteries is gradually increasing.

Such a battery is charged through a charging device, and charging and discharging are continuously used to supply electrical energy stored in the battery to the electronic device.

In the case of such a lead-acid battery, the manufacturer's recommended life span is about 2 to 5 years, but various batteries such as long life-battery and nickel-hydrogen battery have been developed and used due to the recent development of technology. .

The service life of a battery is greatly affected by its performance and lifespan by the operating environment such as ambient temperature, charging and discharging conditions, and overcharge or irreparable discharge due to an abnormality of the charging device or user's carelessness. Overdischarge), cell failure inside the battery, abnormality of charging device, thermal runaway due to heat generation, etc., suddenly deteriorate performance or shorten the life, and discharge capacity decreases due to deterioration of pole plates or poles. It is not possible to store or supply the electric energy normally due to the loss, so starting of a car or an emergency generator is impossible, and power failure is not compensated in the emergency power supply device, which may cause a great inconvenience or a dangerous situation for the user.

In addition, when charging or discharging a battery that is over-charged or deteriorated with a battery voltage higher than a threshold value due to a charging device, there is a problem that an electric device malfunctions or malfunctions with explosion risk. Methods are tried and developed.

For example, in Korean Patent Publication No. 10-2006-0130509, 'Method and Apparatus for Adjusting the Charge or Discharge Output of Battery', the voltage of the battery cell or pack is measured to limit the predetermined power to correspond to the maximum output of the battery estimated in the previous step.
