Abstract

The embodiment of the invention discloses a battery pack equalization control method and device, and equalization control equipment. The control method comprises steps: when a whole vehicle power downinstruction is received or charging of the battery pack is detected to be over, a first to-be-equalized cathode mix in the battery pack is determined; first equalization need time for the first to-be-equalized cathode mix is calculated; and according to the first equalization need time, the first to-be-equalized cathode mix is controlled to be equalized. Through the equalization control method and the device, and the equalization control equipment disclosed in the embodiment of the invention, after the whole vehicle is power-down or the charging of the battery pack is over, the battery pack is controlled to start equalization, and the problem of inadequate equalization of the battery pack can be solved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method and device for equalizing control of a battery pack, and equalizing control equipment. Background technique [0002] In recent years, the broad prospects of new energy vehicles have promoted the rapid development of the power battery industry. As the core component of new energy vehicles, power battery packs have a direct impact on the performance of the vehicle. [0003] The power battery pack is composed of multiple cells connected in series. Due to the difference in the self-discharge rate of the cells, the battery pack will have the problem of inconsistent available capacity of each cell after a period of operation. The inconsistency of the battery pack is an important factor that leads to the performance degradation of the whole pack, so the battery pack needs to be balanced by means of equalization. [0004] At present, the equalization process of the battery pa...
