It is on the basis of integrated charging management chip MAX1898EBU42 to charge control module. It also has some protection functions, for example charging, overvoltage protection and temperature protection. It used AT89C51 as the core of the control system, to achieve full automatically disconnect and alarm to remind users can extend battery life. ADC0832 analog-to-digital conversion, with the acquisition of voltage, through LCD1602 LCD display voltage and charge process. This paper uses the combination of hard and soft to control to charge intelligently. The experiment proves that the design of the charger has low power consumption, system stable and reliable work, high intelligent degree, and low cost, low loss, high security, high service life. It will be the ideal product in life.
