WIPO Patent Application WO/2018/121183

Kind Code:

A1

Abstract:

Provided are a method and device for estimating utility of replacement of a battery pack for an electric vehicle and a charging management method and system based on the above method and device. 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. The utility value represents a degree of influence of replacement of the first battery pack with the second battery pack over service efficiency and service life of a battery pack set comprising the first battery pack and the second battery pack. The present invention facilitates improving service efficiency of a managed battery in a battery replacement mode and extending overall service life of the battery.
