Design of Smart Charger
摘要：本设计以德州仪器公司的MSP430F149单片机来设计一种智能充电器。该智能充电器通过采样电路把相关电池充电状态的充电电流、电池电压和温度信号送入单片机的A/D转换口进行转换，然后单片机根据模糊控制充电算法来改变降压斩波控制器BUCK电路的PWM脉冲输入波的占空比，从而达到来实现对充电过程的智能控制，此外该系统还包括有相应的显示电路、键盘电路以及报警电路，用来输入一些充电参数且通过LCD显示器和声光报警来做出系统的相关提示。本智能充电器设计的模糊控制充电策略，进行智能控制，从而实现数字化、智能化、通用化和低功耗的特点。
Abstract: this design is to build a smart charger using Texas Instruments’ MSP430F149 microcontroller. The smart charger send charging current, battery voltage and temperature signal at certain charging state to the microcontroller’s A/D interface for conversion via sampling circuit. The microcontroller then change the duty cycle of the PWM pulse input wave of chopper controller’s buck circuit based on fuzzy control charging algorithm, realizing smart control of charging process. The system also includes display circuit, keyboard circuit and alarm circuit for the input of charging parameters, and prompts charging state via LCD display and sound/light alarm. This smart charger utilizes fuzzy algorithm for smart control, showing digitalization, intelligence, universalization, and low-power features.
