Abstract

The invention discloses a battery pack for an electric vehicle. The battery pack comprises a shell, a battery group and a battery management part, wherein a battery group placement area and an auxiliary part placement area are formed in the shell; a heat dissipation device is arranged on the shell; the battery group comprises a plurality of battery units and is arranged in the battery group placement area of the shell; each battery unit is a basic battery module which comprises a plurality of battery monomers and battery brackets; and the battery management part is connected with the battery group and arranged in the auxiliary part placement area of the shell. According to the battery pack for the electric vehicle, the battery group and various auxiliary parts such as the battery management part can be arranged in the battery pack, so the battery pack has integrated functions; and by adoption of a modular battery unit design method, requirements of different electric vehicles on the size, voltage, capacity, safety and the like of the battery pack can be met according to different combinations of the battery units.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery pack for electric vehicles. Background technique [0002] As the main energy storage element of electric vehicles, batteries are the key components of electric vehicles and directly affect the performance of electric vehicles. In order to facilitate the installation of batteries in electric vehicles, many manufacturers of electric vehicles currently integrate multiple batteries into one battery pack by placing batteries in battery packs, and then install the battery packs on electric vehicles. Powering electric vehicles. However, this kind of battery pack is only used to accommodate the battery, and its function is relatively single. Many components used with the battery need to be connected to the battery pack, which makes the arrangement of the internal components of the electric vehicle complicated and inefficient, and is also not conducive to maintenance ...
