The system can simultaneously on a lithium battery and 13 nickel rechargeable battery, such as stability, great flexibility. In addition, the charge current can be adjusted freely from 50~400 mA continuously in the constant current charging process, and the output voltage can be achieved 0~10 V continuous adjustment in the constant pressure charging. Experimental results show that the system effectively controlling the charging process of the batteries , which function can meet the requirements of the topic, with its charging fast, efficient, and reliable, will not damage the battery or shorten battery life, and finally can achieve the charging process Intelligent Control.Key Words:The
