The stable operation of new energy vehicle depends on the SOC estimation of lithium battery.In this regard,an SOC estimation method of lithium battery based on FFRLS and GSAPF was proposed.On the basis of using RLS to identify the parameter of lithium battery,the forgetting factor was introduced,and the weights of old data and new data were redistributed through the forgetting factor,so as to reduce the data saturation phenomenon of RLS,and the SOC of lithium battery was estimated by combining GSAPF.Experimental result shows that this method has high precision.
