AI Technical Summary

Technical Problem

Traditional battery pack cooling methods are slow and have limited cooling capacity, which affects the performance of devices using the battery.

Method used

A battery pack structure is designed, including a housing assembly and connectors. By providing a first opening and a second opening that are connected in the housing assembly, and providing a first channel therein, external air can flow to remove the heat from the battery cell assembly, thereby improving heat dissipation efficiency.

Benefits of technology

By allowing external air to flow within the channel, heat from the battery cell components is effectively dissipated, improving the heat dissipation efficiency of the battery pack. This makes it suitable for both static and dynamic devices, enabling rapid heat dissipation.

Abstract

Embodiments of the present application provide a battery pack and an electric device with the battery pack. The battery pack comprises a housing assembly, a first connecting member and a cell assembly. The housing assembly has a first space. The housing assembly is provided with a first opening and a second opening communicating with the first space. The first connecting member is accommodated in the first space. The first connecting member is provided with a first channel. The first opening and the second opening communicate through the first channel. At least part of the cell assembly is arranged in the first space. In a first direction, projections of the first opening and the second opening are separated from a projection of the cell assembly. The first direction is a stacking direction of cells in the cell assembly. Heat of the cell assembly of the battery pack flows in the first channel through external air and is dissipated to the external environment, thereby improving the heat dissipation efficiency of the cell assembly.
