The method comprises the following steps: acquiring state data associated with a first battery pack and a second battery pack, the state data comprising usage history of the first battery pack and performance parameters of the first battery pack and the second battery pack; and determining a utility value according to the state data, wherein the utility value is used to characterize a degree of impact of an operation of replacing the first battery pack with the second battery pack on the service efficiency and service life of a battery pack set to which the first battery pack and the second battery pack belong. The method facilitates improving the service efficiency of a managed battery in a battery swap mode and extending the overall service life thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for determining utility of replacement of battery pack for electric vehicle","description":"Provided are a method and device for estimating the utility of replacement of a battery pack for an electric vehicle, and a charging management method and system based on the method and device.
