Abstract

The invention discloses a battery module group of an electric vehicle, which comprises several batteries and a plurality of flexible connection devices which can be connected to each of the batteries respectively, and all the batteries are spliced ​​together and conducted. The flexible battery module provided by the present invention can be attached to a curved surface, so it can be more flexibly arranged on a vehicle.

Description

technical field [0001] The invention relates to the field of automobile power, in particular to a battery module of an electric automobile. Background technique [0002] With the improvement of environmental protection standards and the development of electric vehicle technology, electric vehicles are gradually replacing traditional cars. [0003] The power of electric vehicles comes from the on-board battery. The volume of the battery often determines the capacity of the battery. Therefore, the battery of an electric vehicle is generally large, and a large space needs to be reserved for the installation of the battery, such as: the chassis of the car, the trunk or Behind the seat etc. This makes the arrangement of the space in the car subject to many restrictions. [0004] Therefore, how to reduce the limitation of the car battery on the interior space of the car is a technical problem that those skilled in the art need to solve at present. Contents of the invention ...
