无线识别装置的无线智能充电器设计

摘要

充电器对充、放电电流、充电电压、温度等的监控需求越来越严格.文中基于AVR单片机实现无线智能充电器的设计,使用该设备充电时,只需将被充电电池放在充电器上,通过无线的方式就可以将充电器的能量及信息与电池进行传递,实现安全通信,间接地控制电池充电,做到无线充电和智能化,从而省去了电线连接的过程.可实时采集电池端电压、充电电流、电池温度、充电时间,并对充电过程中各个参数值进行智能控制,同时系统中还设计了充电保护电路,以防止电池的过充和过放对电池造成损害.%The charger to recharge and discharge current, voltage, temperature monitoring needs to be more strict.This design is based on AVR microcomputer wireless intellectual charger.For this equipment charge, it only will be placed on the rechargeable battery charger.In wireless mode the energy and information of the changer and the battery can be transmitted, to achieve the safety communication, indirect control battery charging, wireless, truly intelligent charging, and to eliminate the wire.The real-time data acquisition, battery charging electric current, voltage, temperature, battery charging time, and various parameters in the process of charging an intelligent control system are designed, as well as the charging protection circuit, in order to prevent the battery overcharge for battery and damage.
