可编程电池充电器设计

摘要

为实现对不同充电方式的可编程控制的目的，采用由BUCK电路、STC12C5A60S2单片机和上位机软件组成的可编程电池充电器设计方案。通过对通用充电器与可编程电池充电器对锂电池充电测试结果的对比分析表明，本设计能够实现恒流、恒压以及混合多段式充电，合理控制充电过程能更好的利用电池的容量。本充电器可用于研究不同电池的最佳充电方案。%In this paper, in order to operate at different charging modes by programmable controlling, the design of a programmable battery charger including BUCK converter, STC12C5A60S2 MCU and computer software, was proposed. The charging test of lithium battery show that the charger has a great charging performance in constant current, constant voltage and multistage modes. Moreover, its capacity can be largely improved by controlling the charging process reasonably and this charger can also be used to study the optimal charging strategy of different batteries.
