Abstract

The invention discloses a full-life-cycle cost evaluation method for gradient utilization of a lithium iron phosphate power battery. The method comprises the following steps of S1, performing gradientutilization grading on the power battery according to the SOH of the lithium iron phosphate power battery; S2, constructing a battery use total capacity model in each gradient utilization period; S3,constructing a cost model of each gradient utilization period; and S4, estimating a full-life-cycle cost change trend of the lithium iron phosphate power battery according to the data obtained in steps S1-S3, and outputting a result. Compared with prior art, the invention innovatively provides the full-life-cycle cost evaluation method for gradient utilization of the lithium iron phosphate powerbattery; the full-life-cycle cost of an electric vehicle power battery can be reasonably evaluated; cost utilization and cost sharing of each period in full-life-cycle of the power battery are divided; and the method has an important meaning for defining and evaluating value utilization and cost sharing of the power battery in an electric vehicle period and other application periods.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a method for estimating the life cycle cost of a lithium iron phosphate power battery cascade utilization. Background technique [0002] Power batteries are an important part of electric vehicles, and the cost of power batteries accounts for about 40% of the entire cost of electric vehicles. At present, although the cost of power batteries is mainly borne by electric vehicle manufacturers, in fact, it is borne by consumers during the specific use process. The high cost will limit the further development of the electric vehicle industry. [0003] In addition to reducing the production cost of power batteries through the research and development of new technologies and new products, it is also possible to reasonably estimate the full life cycle cost of electric vehicle power batteries and allocate the cost of power batteries to all stages of their life cycle. Significantly...
