Description

Technical Field

[0001] This utility model applies to the field of battery PACK technology, specifically relating to the fixing, heat preservation, and protection of battery modules, and particularly to an EPP box for the protection and fixing of battery modules inside a battery PACK pack. Background Technology

[0002] The conventional insulation method for existing battery modules in two-wheeled / three-wheeled vehicles is to use epoxy boards for insulation protection around the perimeter. The battery pack is fixed in place by foam filling, which is costly. Furthermore, when the battery pack is used in low-temperature environments, the lack of insulation inside the box can cause the battery pack to fail to start or reduce its performance, thus reducing the vehicle's driving range. Therefore, we propose an EPP box for the protection and fixation of battery modules inside the battery pack to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the conventional insulation method for battery modules using epoxy boards for insulation protection, and the use of foam filling for fixing the battery pack in the enclosure. These methods are costly and, when the battery pack is used in low-temperature environments, the lack of insulation inside the enclosure can lead to the battery pack failing to start or experiencing reduced performance, resulting in a decrease in the vehicle's driving range. The invention proposes an EPP enclosure for the protection and fixing of battery modules inside the battery pack.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An EPP enclosure for protecting and securing battery modules inside a battery pack includes a battery enclosure, an EPP enclosure on the inner wall of the battery enclosure, battery modules and series bars on the inner wall of the EPP enclosure, and the battery modules and series bars are compatible with each other. An EPP cover is provided on the top of the EPP enclosure, and a battery cover is provided on the top of the battery enclosure.

[0006] As a preferred embodiment of this utility model, the inner wall of the EPP box is fixedly connected with multiple battery module partitions at equal intervals, and the number of battery module partitions is three.

[0007] As a preferred embodiment of this utility model, the top of the EPP box is provided with a limiting slot and a V-shaped limit, both of which are adapted to the EPP box cover.

[0008] As a preferred embodiment of this utility model, the right side of the EPP box is symmetrically provided with positive and negative electrode outlets, and the number of positive and negative electrode outlets is two.

[0009] As a preferred embodiment of this utility model, both the EPP box body and the EPP box cover are made of 15 times the amount of EPP material, with a density of 60Kg / m³.

[0010] This invention effectively solves the problems of fixing, heat preservation, and protection of the battery pack inside the box through a simple structure, effectively reduces the shaking problem of the internal battery modules during use, and effectively enhances the heat preservation performance of the battery pack in low-temperature environments, thus having good practicality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0018] Reference Figures 1-5 An EPP enclosure for protecting and securing the battery modules inside a battery pack, including...

[0019] The battery box 1 has an EPP box 2 on its inner wall, and a battery module 3 and a series bar 4 are provided on the inner wall of the EPP box 2. The battery module 3 and the series bar 4 are compatible. The top of the EPP box 2 has an EPP box cover 5, and the top of the battery box 1 has a battery box cover 6.

[0020] As a preferred embodiment of this utility model, the inner wall of the EPP housing 2 is fixedly connected with multiple battery module partitions 7 at equal intervals, and the number of battery module partitions 7 is three.

[0021] As a preferred embodiment of this utility model, the top of the EPP box 2 is provided with a limiting slot 9 and a V-shaped limit 10, both of which are adapted to the EPP box cover 5.

[0022] As a preferred embodiment of this utility model, the right side of the EPP box 2 is symmetrically provided with positive and negative electrode outlets 8, and the number of positive and negative electrode outlets 8 is two.

[0023] As a preferred embodiment of this utility model, both the EPP box body 2 and the EPP box cover 5 are made of 15 times the amount of EPP material, with a density of 60Kg / m³.

[0024] The working principle of this utility model is as follows: Both the EPP housing 2 and the EPP cover 5 are made of 15 times EPP with a density of 60 kg / m³. Expanded polypropylene (EPP) is a high-performance, highly crystalline polymer and gas composite material with excellent shock absorption and heat insulation properties. It has a high recovery rate after deformation, is environmentally friendly, non-toxic, odorless, and has good heat resistance, chemical corrosion resistance, oil resistance, and biodegradability. The battery module 3, EPP housing 2, and EPP cover 5 are all molded parts. In actual use, each battery module 3 is first assembled according to the usage requirements. After spot welding the current-carrying plates, each battery module 3 is assembled into the EPP housing 2 in sequence. After the battery module 3 is assembled, the module series bus 4 is installed and the acquisition line is connected. Finally, the EPP cover 5 is installed. To disassemble, simply open the EPP cover 5, remove the series bus 4 and the acquisition line, and then take out each module.
