Abstract

The invention discloses a soft package battery module frame assembly, a battery assembly and a new energy automobile, relates to the technical field of new energy automobiles, and solves the technicalproblem that a frame structure of an aluminum shell battery module in the prior art is not suitable for a soft package battery module. The soft package battery module frame assembly is provided witha battery module mounting part and a PCB data acquisition board mounting groove. The soft package battery module frame assembly sleeves a battery module and enables the battery module to be located inthe battery module mounting part, and tabs on the two sides of the battery module are exposed. The PCB data acquisition board mounting groove is used for mounting a PCB data acquisition board and enabling the PCB data acquisition board to be connected with tabs on two sides of the battery module. According to the soft package battery module frame assembly, the PCB data acquisition board can conveniently acquire the voltage and the temperature of the battery module, and the acquisition mode of the voltage and the temperature of tabs at two sides of the soft package battery module is effectively improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a soft pack battery module frame assembly, a battery assembly with the soft pack battery module frame assembly, and a new energy vehicle with the battery assembly. Background technique [0002] With the development of new energy vehicles and the maturity of power batteries, power batteries are developing towards higher energy density, smaller volume and higher power density. Compared with aluminum-cased batteries and steel-cased prismatic batteries, pouch batteries packaged with aluminum-plastic film have the advantages of small size, light weight, high safety, and various designs of external dimensions. Therefore, battery cells composed of pouch batteries are more and more widely used in electric vehicles as energy storage devices. [0003] The battery module is the core of the energy system, and the battery management system must monitor the voltage and temperature...
