Abstract

The invention relates to new energy vehicle technology, in particular to a method and device for estimating the utility of the electric car battery pack placement and a charging management method andsystem based on the method and device. The method for estimating the utility of the electric car battery pack placement comprises the following steps that status data associated with a first battery pack and a second battery pack are obtained, and the status data comprise application history of the first battery pack and performance parameters of the second battery pack; the utility value is determined based on the status data, and the utility value is used for representing the effect degree of the operation of replacing the first battery pack by using the second battery pack to the use efficiency and service life of a battery pack assembly which the second battery pack is belonged. The method and device for determining the utility of the electric car battery pack placement is conducive toimproving the use efficiency and prolonging the overall life of managed batteries under the switching mode.

Description

technical field [0001] The present invention relates to new energy vehicle technology, in particular to a method and device for estimating the effectiveness of battery pack replacement in electric vehicles and a charge management method and system based on the method and device. Background technique [0002] In order to significantly reduce the carbon dioxide emissions of automobiles, the automobile industry is investing a lot of manpower and material resources in the research and development of new automobiles that use electricity as a power source, such as hybrid electric vehicles and pure electric vehicles. Pure electric vehicles refer to vehicles that use on-board batteries as the power source, drive the wheels with motors, and meet the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. [0003] However, there are still many difficulties in the popularization and p...
