摘　　要：为了对同线扩音电话中的镍氢电池组提供尽可能完备的保护和管理,并解决镍氢电池在小电流充电模式下的效率问题,提出了一种镍氢电池的充放电管理单元。基于BUCK-BOOST芯片设计了一个宽输入范围、高效率的稳压电源;基于PIC12F615单片机和LTC3114芯片设计了充放电管理单元,确定了系统工艺,设计了系统电路,测试了相关功能。经实验研究表明,该电池管理单元充电效率高,工作灵活可靠,取得了良好的效果。In order to protect and manage the nickel-metal hydrogen battery pack in the same line of telephone and to solve the problem of the efficiency of nickel-metal hydrogen battery in low current charging mode, propose a charge and discharge management unit for nickel-metal hydrogen battery. Design a wide input range and high efficiency power supply based on BUCK-BOOST chip. Design the charging and discharging management unit which based on PIC12F615 MCU and LTC3114 chip, confirm the system technology, design the system circuit and test the related functions. The experimental study shows that the battery management unit is efficient, the operation is flexible and reliable, and has achieved good results.
