摘　　要：为了利用锂离子电池放电特性来延长移动设备的使用时间,分析了锂离子电池容量消耗的特点,提出了基于该容量消耗特点的考虑电池放电特性的电压调节策略BADVS。把锂离子电池放电过程分为线性放电和非线性放电两个阶段,提出的BADVS策略在不同的放电阶段采用不同的优化目标和不同的优化方法。仿真实验结果表明,该策略在电池放电的整个过程中都能有效地减少电池容量消耗。To extend the using time of mobile devices according to the lithium-ion battery＇s discharge behavior, the characteristic of capacity consumption for lithium-ion battery was analyzed and a battery-aware dynamic voltage scaling algorithm BADVS based on it was presented. The battery discharge was divided into linear discharge and non-linear discharge two phases. The proposed algorithm had different optimal objectives and methods during different discharge phases. The simulation results show that the algorithm effectively makes a reduction of battery capacity consumption during the whole discharge procedure.
