Abstract

어댑터 및 배터리가 연결되어 있는지를 검사하고, 어댑터 및 배터리가 연결되어 있을 경우에 변수를 초기화하면서 충전 시작신호를 출력한 뒤에 어댑터 및 배터리가 연결되어 있는지 다시 한번 검사하고, 어댑터 및 배터리가 계속 연결되어 있을 경우에 충전시간이 초과되었는지를 판단하고, 충전시간이 초과되지 않았을 경우에 검사간격 시간이 초과되었는지를 판단하여 검사간격 시간이 초과되었으면 배터리의 전압을 감지하고, 카운트 변수가 n값보다 작을 경우에 감지된 배터리의 전압이 이전 배터리 전압보다 작은지를 판단하여 작을 경우에 카운트 변수를 1 증가시키고, 카운트 변수가 n값보다 크거나 같을 경우에 감지된 배터리의 전압이 이전 배터리 전압보다 작은지를 판단하여 작지않을 경우에 카운트 변수를 0으로 치환시키고, 전압을 이전 배터리 전압으로 치환시키고, 충전 시간이 초과되었거나 배터리의 전압이 이전 배터리 전압보다 작다고 n번 판단될 경우에 충전 중지신호를 출력한 뒤에 종료되는 단계로 구성됨으로써, 현재 감지된 충전 배터리의 전압이 이전에 감지된 충전 배터리의 전압보다 작은 경우가 여러번 검출될 경우에 충전 배터리가 만충전되었다고 판단을 하여 배터리의 충전을 중지함으로써 배터리의 충전에 대한 신뢰성을 높인 배터리 충전 제어방법에 관한 것.Checks if the adapter and battery are connected, outputs the charge start signal while initializing the parameters when the adapter and battery are connected, checks again if the adapter and battery are connected, and keeps the adapter and battery connected. If it is, it determines whether the charging time has been exceeded.If the charging time is not exceeded, it is determined whether the inspection interval time has been exceeded. If the inspection interval time is exceeded, the voltage of the battery is detected. If the detected battery voltage is less than the previous battery voltage is determined to increase the count variable by 1, and if the count variable is greater than or equal to n value is determined whether the detected battery voltage is less than the previous battery voltage If not small, replace the count variable with 0 and transfer the voltage. The battery is configured to replace the battery voltage and terminate after outputting the charge stop signal when it is determined that the charging time has been exceeded or the voltage of the battery is smaller than the previous battery voltage. The present invention relates to a battery charge control method of improving reliability of charging a battery by determining that the rechargeable battery is fully charged when the case where the voltage of the rechargeable battery is less than the detected voltage is detected several times.

어댑터 및 배터리가 연결되어 있는지를 검사하고, 어댑터 및 배터리가 연결되어 있을 경우에 변수를 초기화하면서 동시에 충전 시작신호를 출력한 뒤에 어댑터 및 배터리가 연결되어 있는지 다시 한번 검사하고, 어댑터 및 배터리가 계속 연결되어 있을 경우에 충전시간이 초과되었는지를 판단하고, 충전시간이 초과되지 않았을 경우에 검사간격 시간이 초과되었는지를 판단하여 검사간격 시간이 초과되었으면 배터리의 전압을 감지하고, 카운트 변수가 n값보다 작을 경우에 감지된 배터리의 전압이 이전 배터리 전압보다 작은지를 판단하여 감지된 배터리의 전압이 이전 배터리의 전압보다 작을 경우에 카운트 변소를 1 증가시키고, 카운트 변수가 n값보다 크거나 같을 경우에 감지된 배터리의 전압이 이전 배터리 전압보다 작은지를 판단하여 감지된 배터리의 전압이 이전 배터리의 전압보다 작지 않을 경우에 카운트 변수를 0으로 치환시키고, 전압을 이전 배터리 전압으로 치환시키고, 충전시간이 초과되었거나 감지된 배터리의 전압이 이전 배터리 전압보다 작다고 n번 판단될 경우에 충전 중지신호를 출력한 뒤에 종료되는 단계로 이루어지는 것을 특징으로 하는 배터리 충전 제어방법.Checks if the adapter and battery are connected, initializes the parameters when the adapter and battery are connected, outputs the charge start signal at the same time, checks again that the adapter and battery are connected, and keeps the adapter and battery connected If the test time is exceeded, it is determined whether the charging time has been exceeded. If the test time is exceeded, the battery voltage is detected. In this case, it is determined whether the detected battery voltage is smaller than the previous battery voltage, and the count variation is increased by 1 when the detected battery voltage is lower than the previous battery voltage, and detected when the count variable is greater than or equal to n. Detects whether the voltage of the battery is lower than the previous battery voltage. If the voltage of the battery is not less than the voltage of the previous battery, it is determined n times that the count variable is replaced with 0, the voltage is replaced with the previous battery voltage, the charging time is exceeded or the detected battery voltage is less than the previous battery voltage. The battery charging control method comprising the step of terminating after outputting a stop charge signal.
