Abstract

The invention discloses a battery management system and an electric vehicle. The battery management system comprises a battery management module; the at least two battery cells comprise a shell, a cover plate, a roll core and an acquisition circuit, at least one end of the shell is provided with an opening, and the cover plate is used for sealing the opening end of the shell; the acquisition circuit and the roll core are arranged in the shell, and the acquisition circuit is used for acquiring working parameters of the roll core; wherein the cover plate is provided with a transmission part, and the transmission part is connected with the acquisition circuit; the connecting piece is respectively connected with the battery management module and the transmission part; wherein the transmission part is used for transmitting the working parameters to the battery management module, and the battery management module is used for controlling the working state of the battery cell according to the working parameters. According to the battery module, each battery cell can be independently managed, so that the reliability of the battery module is improved.

Description

Technical field [0001] The present application relates to the field of battery management technology, in particular to a battery management system and electric vehicles. Background [0002] In related technologies, the battery pack includes a plurality of battery modules and battery management modules (BMS), battery management modules and each battery module is connected to collect information about the fixed cells in the battery module. [0003] However, this information only represents the information of some cells in the battery module, so the battery management module cannot manage each cell in the battery module, which affects the reliability of the battery module. Contents of the Invention [0004] The present application is intended to solve at least one of the technical problems present in the prior art. To this end, the present application proposes a battery management system and electric vehicles, which can realize the independent management of each battery cell, ther...
