Abstract

The invention discloses a battery system, a control method and an electric automobile. The battery system comprises a main battery module, a standby battery module and a first electric relay, after being in series connection with the first electric relay, the standby battery module is in parallel connection with the main battery module. Through the adoption of the battery system, the control method and the electric automobile provided by the application of the invention, the available electric quantity of the battery system is improved, and the using time of the battery system is prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery system and a control method. Background technique [0002] Electric vehicles, as the name suggests, refer to vehicles powered by on-board power supplies and driven by motors. The service life and reliability of electric vehicles are mainly determined by the life and reliability of the battery system. [0003] At present, the service life of the battery system of the electric vehicle is generally low, therefore, a battery system with a long service life is urgently needed at present. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, an object of the present invention is to propose a battery system, in which a backup battery module is incorporated into the battery system, which increases the available power of the battery system, and make...
