基于单片机的电动工具锂电池管理系统设计

摘要

Choose the lithium battery whose anode is ternary material, single section voltage 3.6V, and using 3 in series 1 in parallel, the 10.8V lithium variable speed drill as the main object of study and application. Analyzed the lithium batteries in power tool industry facing some problems in the process of application, including:charger, PCM circuit complex, poor reliability, large self power consumption, high cost. Design and development with PIC16F616 SCM as the core of the charge-discharge control system.%选用正极为三元材料的锂电池，单节电压3.6V，3串1并，以10.8V锂电调速电钻为主要研究与应用对象，分析了锂电池在电动工具行业应用过程中所面对的一些问题，包括：充电器、P C M电路复杂、可靠性差、自耗电大、成本高等，并设计开发以P I C16F616单片机为核心控制的充放电系统。
