AI Technical Summary

Technical Problem

The air-cooled structure of the existing battery pack will cause too low temperature in a colder environment, affecting the working condition of the battery pack.

Method used

A new energy battery pack with adjustable air cooling capacity is designed. By setting a heat dissipation component on the end surfaces of the upper case and the lower case, including the main air inlet and the side air inlet, the main air duct and the side air duct are used to introduce and discharge the cooling airflow, and the cooling airflow is closed in a colder environment through an open and closed wind barrier structure to achieve sealing and insulation of the cavity.

Benefits of technology

It effectively improves the temperature control of the battery pack in a colder environment, prevents the temperature from being too low, and ensures the normal working state of the battery components in a colder environment.

Abstract

The utility model discloses an air cooling capacity adjustable new energy battery pack which comprises a lower shell, an upper shell, a battery element and a heat dissipation assembly, and a cavity is formed between the upper shell and the lower shell; the battery element is positioned in the cavity; the heat dissipation assembly comprises a main air inlet and a side air inlet, the main air inlet and the side air inlet are connected to a main air pipeline and a side air pipeline respectively, and air blocking structures capable of being opened and closed are arranged in the main air inlet and the side air inlet respectively. When the battery pack is in a cold use environment, the main air inlet and the side air inlets are closed by the air blocking structure of the heat dissipation assembly, so that cooling airflow cannot enter the cavity, the cavity can be ensured to be in a sealed state, the heat preservation effect on the battery element is further realized, the working state of the battery element in the cold environment is ensured, and the service life of the battery element is prolonged. The problem that the working condition of the battery pack is affected due to the fact that the temperature of the battery pack is too low when an existing air cooling structure of the battery pack is in a cold environment can be effectively solved.
