However, for additional lead-acid battery charge charger charging for a long time exists, the problem of low charging efficiency, and cannot meet the requirements of the modern social production and living fast and efficiently. Therefore, research and development of a smart charger to meet the requirements of the lead-acid battery charging has important practical significance. This paper analyzes the characteristics of lead-acid battery charging, constant current charging, constant voltage charging and floating charge combination of the charging strategy for the system requirements to take charge mode automatically converted automatically determine the charge state of intelligent charging. Intelligent charging method close to acceptable charging current charging curve forlead-acid battery, meet the ideal charging method for lead-acid battery.In order to realize the intelligent charging of the battery pack, using the ATmega16 micro-controller to charge the battery and intelligent control. Introduction of intelligent charger based on ATmega16 MCU control circuit principle and structure, and the design of the software process.Key words：Electric vehicles; Intelligent Charger;AVR microcontroller; stage constant-current / constant-voltage 毕业设计（论文）任务书附表一题目
