To resolve the battery charging problem , designed a AT89S52 microcontroller core universal smart charger, describes working principle, design of intelligent charger features some modes of charging ,and discussed in detail the system of hardware and software implementation. As a result of the high-performance micro-controller and high resolution A/D conversion circuit, ensure that the charger has a very high precision. In the basic parameters characteristics of battery is introduced on the basis of, also introduces the design of hardware system, including data acquisition circuit, control circuit, man-machine interface and microprocessor controller and power part, and the core components of the charger AT89S52 single chip microcomputer was introduced in full. Focus on include the charger software function design, the software control system not only has carried on the demand analysis, must also be charging control system reliability, stability, security and econ
