Description

Technical Field

[0001] The present application belongs to the field of battery technology, and specifically relates to a battery module structure. Background Art

[0002] The battery module is an intermediate energy storage unit between the battery cell and the battery pack. It is formed by connecting multiple cells in series and in parallel, and adding auxiliary structural parts that play the role of collecting current, collecting data, fixing and protecting the cells. The battery cells will generate a lot of heat during the discharge or charging process. If the heat accumulates inside the battery and is not dissipated in time, the temperature of the battery module will continue to rise, which will damage the battery module, cause the cell to bulge and deform, and cause permanent damage and failure of the battery.

[0003] However, most existing battery modules use external structures to dissipate heat for the battery cells, which results in a large overall battery system volume, high cost, uneven overall heat dissipation, and average heat dissipation effect. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of the present application is to provide a battery module structure with simple and compact structure, simple and quick installation and disassembly, reduced cost, uniform heat dissipation and good effect.

[0006] The present application provides a battery module structure, including a main body and a fixing belt, wherein the fixing belt is sleeved on the main body; the main body includes a plurality of battery cells, a plurality of heat sinks and two end plates, the battery cells and the heat sinks are alternately stacked in sequence between the two end plates, and the plurality of battery cells are connected in series.

[0007] Preferably, it further comprises a top plate, wherein the top plate is installed on the top of the main body.

[0008] Preferably, two tab terminals are further included, wherein the tab terminals are mounted on the end plate and connected to the battery cell.

[0009] Preferably, it further comprises a collecting component, and the collecting component is installed on the main body.

[0010] Preferably, two fixing belts are provided, one fixing belt is sleeved on the bottom end of the main body, and the other fixing belt is sleeved on the top end of the main body.

[0011] Preferably, the end plate is provided with a limiting groove, and the fixing belt is installed in the limiting groove.

[0012] Preferably, the heat sink is provided with a heat dissipation duct.

[0013] Preferably, the heat dissipation duct is provided with reinforcing ribs.

[0014] Compared with the prior art, the battery module structure of the present application is provided with multiple heat sinks, and a heat sink is arranged between the battery cells. When the battery cells generate heat, the heat of the battery cells is transferred to the heat sink, and the heat sink dissipates heat for each battery cell, with uniform heat dissipation and good heat dissipation effect. At the same time, a fixing belt is provided, which binds the battery cells and the heat sink between the two end plates. The installation and disassembly are simple and quick, the overall volume is small, and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
