Abstract

The application relates to a method and a device for identifying an abnormal single battery in a storage battery set. The method comprises steps of collecting operation data of the storage battery set, wherein the operation data at least comprise the working voltage value of each single battery of the storage battery set; determining whether a first preset condition is met or not according to the operation data; and when the first preset condition is met, identifying the abnormal single battery according to the corresponding relation between the working voltage value of each single battery of the storage battery set and the single battery. By collecting the working operation data of the storage battery set, the abnormal single battery can be effectively identified using the operation data, and the safety of the storage battery set and the vehicle can be improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a method and device for identifying abnormal single cells of a battery pack. Background technique [0002] New energy vehicles generally refer to new vehicles that use unconventional vehicle fuels as power sources or use conventional vehicle fuels and adopt new vehicle power devices. Currently existing new energy vehicles mainly include hybrid or pure electric vehicles. As the core component of electric vehicles, the battery pack is generally composed of dozens to hundreds of single cells connected in series and parallel. During the long-term charge and discharge process of the battery pack, due to the differences in the charging acceptance capacity, self-discharge rate, and capacity decay rate of the individual cells in the battery pack, the gap in the charge capacity of the individual cells in the battery pack is getting larger and larger. , showing a divergent ...
