本研究利用田口的粒子群优化算法来搜索一个最佳的四阶段恒流充电模式提供最大的容量，以提供最短的充电时间内的长运行时间。目标是基于充电时间和放电容量比两者共享相同权重来最大化所应用的充电模式的成本函数。放电容量比被定义为使用四阶段恒流充电策略在0.3C的恒流下放电直到达到3.0V的预设电压的电池与使用恒流恒压充电方法的电池的总容量。充电时间是4SCC充电过程的总充电持续时间。测试标称电压为3.7 V、额定容量为840 mAh的圆柱形Sanyo UR 14500 P电池。在测试中，允许1.262 C、1.082 C、0.662 C和0.258 C的最佳4SCC顺序将电池充电到标称容量的94.7%，持续67 min，采用0.7C ~ 4.2V的恒流恒压充电方式，截止电流为0.05C，可将电池充电至99.5% 119分钟内达到额定容量。
This study utilizes a Taguchi-based particle swarm optimization algorithm to search an optimal four-stage constant current charge pattern for delivering the maximum capacity to provide long runtimes within the shortest charging time. The goal is to maximize the cost function for the applied charge pattern based on the charging time and discharge capacity ratio that both share the same weight. The discharge capacity ratio is defined as the total capacity of a cell discharged at a constant current of 0.3 C using the four-stage constant current charging strategy until reaching the preset voltage of 3.0 V to the one employs the constant current constant voltage charging method. The charging time is the overall charging duration of the 4SCC charging process. Sanyo UR14500P batteries in the cylindrical shape with a nominal voltage of 3.7 V and a rated capacity of 840 mAh are tested. In the tests, the optimal 4SCC sequence of 1.262 C, 1.082 C, 0.662 C and 0.258 C is allowed to charge the battery up to 94.7% of the nominal capacity for 67 min, and the constant current constant voltage charging arrangement of 0.7 C to 4.2 V and the cut-off of 0.05 C are used to charge the battery up to 99.5% of the nominal capacity in 119 min.
