AI Technical Summary

Technical Problem

The heat generated by the battery pack during operation causes the temperature to rise, reducing the safety and reliability of the battery pack. At the same time, the existing cold plate cooling method makes the battery pack complex structure and high preparation cost.

Method used

A battery pack is designed, and a first and second cooling plates are respectively arranged on the outer walls of the battery pack, and coolant is input and outputted through the first and second connectors respectively, simplifying the setting of the coolant pipeline and reducing structural complexity and preparation cost.

Benefits of technology

By simplifying the design of the cooling system, the preparation cost and structural complexity of the battery pack are reduced, while improving the heat dissipation efficiency and reliability of the battery pack.

Abstract

The utility model provides a battery pack and an automobile, and relates to the technical field of batteries. The battery pack comprises a shell, a battery pack, a first cooling plate, a second cooling plate, a first connecting piece and a second connecting piece, by arranging the first connecting piece, cooling liquid can be input into the first cooling plate and the second cooling plate at the same time, and the cooling liquid in the first cooling plate and the second cooling plate can be discharged through the second connecting piece at the same time, so that a cooling liquid pipeline does not need to be independently arranged for the first cooling plate and the second cooling plate, and the structure of the battery pack is simplified; and the preparation cost of the battery pack is reduced. The first cooling plate and the second cooling plate are further connected through a first connecting piece and a second connecting piece, so that the first cooling plate and the second cooling plate can be relatively fixed. In addition, the first cooling plate and the second cooling plate are arranged on the two opposite sides of the battery pack and can also play a role in limiting and fixing the battery pack, so that the structure of the battery pack is more stable, and the structure of the battery pack is more stable.
