摘要: This paper presents a variable-current charging strategy of Li-ion batteries. Since the battery characteristics vary with state charge ( SOC ), it is more reasonable to divide process based on than cut off voltage. We find an optimal pattern proposed by Non-dominated Sorting Genetic Algorithm-III (NSGA-III). The Second-order Thevenin model established simulate process. Verification experiments are performed and results show that obtained has temperature loss reduction 2.9 °C 0.5% compared constant current-constant voltage (CC-CV) under same time capacity.
