Abstract

The invention discloses a lithium battery pack, which comprises a battery box. There is an installation cavity in the middle of the battery box. A suspended installation plate is installed on one side of the inner wall of the installation cavity. A battery cavity is arranged in the installation plate. Each battery cavity Each is provided with a lithium battery cell, one side of the installation plate is installed on one side of the inner wall of the installation cavity through an elastic connection structure, and a heat exchange component is arranged on the top surface of the installation cavity, facing the bottom surface of the installation cavity of the heat exchange component A drainage assembly is arranged on the top, and cooling holes are arranged on the bottom of the battery box. The invention is simple in structure, has very good cushioning performance, can effectively cope with vibration occasions, and can use vibration force to realize heat exchange, and has very good waterproof performance to ensure that no water accumulates inside.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a lithium battery pack. Background technique [0002] The lithium battery pack installs more than one battery cell in a battery box to form a complete battery pack. This kind of battery pack is large in size and heavy in weight. When it is used, it is used in many occasions under vibration. Therefore, the traditional The anti-seismic performance of the lithium battery pack is poor, which causes the lithium battery to be in a vibration environment all the time, which makes the lithium battery pack face the situation of crushing and rupture, and the service life is short. Moreover, the lithium battery pack will generate a lot of heat during use, which will seriously affect the service life of the lithium battery pack, and the external water will enter the battery box through the cooling holes, causing a short circuit to the battery cells, and the waterproof effect is poor. Conten...
