摘　　要：详细介绍了采用PIC16C74单片机为控制核心的锂离子电池(7串电池组)保护电路的硬件、软件设计。利用PIC16C74单片机强大的判断和逻辑运算能力及软件的灵活性,实现了对锂离子电池工作状态的检测,及对锂电池的防过充电、防过放电及防止过电流功能。This paper deals mainly with the hardware and software design of the protective circuit for lithium-ion batteries （7 in series）,whose control center is PIC16C74. By making full use of the powerful judgment and logic calculation of PIC16C74 as well as the flexible software, this paper tests the working condition of the lithium battery and realizes the protection performance of overcharge, overdischarge and over current.
