摘要：由于电池的充电过程对其寿命影响最大，根据镍镉电池的特性，设计了以PIC16F73作为控制器的智能镍镉电池充电器。利用电池的电压和温度数据作为输入,设计了模糊控制器，采用模糊控制方法对电池进行充电以保证电池的充足率。利用PIC16F73的I2C接口进行组网，在PC机的监控下可以同时对40组矿灯电池进行充电。实践证明，该智能充电器智能化程度高，体积小，成本低，工作稳定可靠，具有较好的实用价值。

Abstract: For the charging of battery has the most effect on its lifetime, taking the PIC16F73 as controller, the intelligent charger was designed, according to the characteristic of Ni/Ca battery. Using the battery voltage and temperature data as input, a fuzzy controller was designed to charge battery, the full capacity of battery was guaranteed. Furthermore, forty batteries could be charged once time under the monitoring of PC, using the I2C interface of PIC16F73. Experiment results prove that the charger has an intelligent performance, works steadily, and has the excellent practical value.
Key words: Ni/Ca battery; PIC16F73; fuzzy control; I2C bus
