Problems solved by technology

[0004] At present, in order to reduce the weight of the battery pack, that is, to reduce the weight of the battery pack and increase the specific capacity of the battery pack, structural glue is usually used to bond multiple single cells to assemble a battery pack. In the medium and long-term vibration state, the structural adhesive is very easy to fail, which makes the internal structure of the battery pack unstable

Abstract

The invention relates to the field of batteries, and discloses a battery pack. The battery pack (1) comprises a battery unit (10). The battery unit (10) comprises a plurality of single batteries (100), a connecting component (11) is arranged on each single battery (100), and the battery pack (1) further comprises a supporting component (12) which can be matched with the connecting components (11)to connect the connecting components (11) of the adjacent single batteries (100). According to the invention, the connecting components are arranged on the single batteries of the battery pack, and the supporting components which can be matched with the connecting components are further arranged in the battery pack so as to connect the connecting components of the adjacent single batteries, so that the overall structure of the battery pack is firm.

Description

technical field [0001] The present invention relates to the field of batteries, in particular to a battery pack. Background technique [0002] Electric vehicle, that is, electric drive vehicle, also known as electric drive vehicle. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle is a vehicle that uses the battery as the energy source, and converts the electrical energy into mechanical energy through the controller, motor and other components to control the current size and change the speed. As a new energy green vehicle, electric vehicles have significant effects in energy saving and environmental protection, and thus have been more and more widely used. [0003] In order to enable electric vehicles to achieve higher cruising range, it is necessary to install battery packs on electric vehicles such as electric vehicles. A plurality of single cells are usually arranged in a battery pack to improve t...
