Battery Module Insulation Bracket

Battery Module Insulation Bracket

The Battery Module Insulation Bracket utilizes premium battery-grade, flame-retardant modified engineering plastics—primarily glass fiber-reinforced PA66 and weather-resistant PC/ABS alloys. Specially formulated to meet the UL94 V-0 high flame-retardancy standard, the material offers exceptional performance, including superior dielectric strength, resistance to electrolyte corrosion and thermal shock (high/low temperatures), as well as resistance to aging and vibration fatigue. It is designed to withstand the harsh operating conditions inside battery packs—such as high temperatures, fluctuating thermal cycles, continuous vibration, and enclosed, humid environments—thereby ensuring the safety and stability of the battery module at the material level.

Leveraging an integrated precision injection molding process, the product features complex, composite structures—such as precise cell-positioning slots, reinforcing ribs, locating bosses, mounting clips, open-work cooling channels, and embedded screw bosses—formed in a single step. This ensures tight dimensional tolerances and high batch-to-batch consistency, eliminating the need for secondary processing steps like trimming, drilling, or additional assembly; this significantly simplifies the battery module assembly process and boosts efficiency on automated production lines. The lightweight, high-strength structural design ensures rigid support and secure cell positioning while incorporating standardized cooling air channels to accelerate heat dissipation, effectively reducing the risk of thermal runaway and extending the overall service life of the battery module.

The product offers exceptional versatility, compatible with various specifications of prismatic and cylindrical cell modules. It is suitable for a wide range of applications, including power battery packs for new energy vehicles, portable energy storage units, commercial and industrial energy storage cabinets, and PV-integrated storage systems. Fully customized services are available; dedicated molds can be developed based on customer 3D drawings, cell parameters, module structures, and protection standards to precisely meet specific requirements for structural layout, insulation, thermal management, and assembly. The product supports mass production and complies with the standards required for various mid-to-high-end new energy equipment applications.

Common types of battery module insulation brackets include:

1. Prismatic Cell Insulation Brackets (EV Power Battery Type): Injection-molded from light gray or black flame-retardant PA66; features precise cell positioning slots, heat dissipation cutouts, and locking clips. With a structured design, they are ideal for EV power battery modules, providing insulation and secure positioning. These precision-molded parts include reinforcing ribs, heat dissipation cutouts, and mounting holes, and are widely used inside new energy vehicle battery packs.

2. Cylindrical Cell Insulation Brackets (General-Purpose Energy Storage Type): Integrated plastic brackets with multiple slots and independent cell separators; designed with gaps for heat dissipation to prevent short circuits and cell movement. Compatible with 18650, 21700, and large cylindrical energy storage cells, they are designed for mass module assembly. Made from black flame-retardant PA66 via integrated injection molding, they feature circular cell slots and locking clips, serving residential energy storage and large cylindrical lithium battery modules by ensuring cell isolation and secure positioning.

3. Precision Brackets with Reinforcing Ribs (High-Strength Type): Features integrated surface ribs, screw bosses, and sealing slots; offers uniform wall thickness and dimensional stability. Resistant to vibration and electrolyte exposure, these brackets meet the rigorous operating conditions of automotive power battery packs and offer high dimensional precision.

4. Module Assembly Display Brackets (Finished Assembly Type): Showcases the integrated assembly of brackets and cells, clearly demonstrating insulation, orderly arrangement, and airflow channel structures; ideal for displaying real-world product applications.

5. Array-Style Cell Insulation Trays: Integrated multi-cavity design allowing for mass cell arrangement; incorporates features for both insulation and heat dissipation/airflow management, making them suitable for assembling industrial and commercial energy storage battery modules.
