초록

A voltage setting value for charging a battery starts from a first constant voltage level less than a full battery voltage and after a period of time the battery voltage reaches that first level and the charging current begins to decrease. The charging current decrease is detected and the voltage value is increased to a next constant voltage level and the process is repeated until the constant voltage level is reached that equals the full battery voltage. Each time the voltage level is changed the corresponding percentage of the battery voltage is displa...
