Completo Battery Energy Storage Cabinet Production Line

Etapa 01/09Battery Energy Storage

Raw Sheet Metal

BESS cabinet production starts with cold-rolled galvanized steel, stainless steel, or aluminum sheet. Material is sheared to line-ready blanks and inspected for flatness before large-panel cutting and forming.

• Galvanized steel most common for outdoor BESS cabinets
• Typical thickness: 1.5mm – 3.0mm for container bodies
• Flatness check before laser cutting and panel bending

Next: Fiber Laser Cutting

Step 02 / 09Battery Energy Storage

Corte a laser de fibra

Fiber laser cutting blanks large cabinet side panels, hinged doors, base trays, cable gland plates, and mounting brackets with ±0.1mm accuracy — the precision step for every battery storage enclosure line.

• Door, side panel, and base tray blanking
• Cable gland, window, and hinge cutouts
• Galvanized, stainless, and mild steel processing

Next: Automatic Panel Bending

Step 03 / 09Battery Energy Storage

Automatic Panel Bending

The core forming step on BESS lines — automatic panel benders form four-side cabinet bodies, access doors, and PCS covers in one pass with consistent flange width for gasket-ready outdoor sealing.

• One-pass U-box and cabinet body forming
• Door and cover production with ±0.1° accuracy
• Standardized ESS cabinet models at high volume

Next: CNC Press Brake

Step 04 / 09Battery Energy Storage

Freio de prensa CNC

Press brakes complement the panel bender — forming battery rack channels, base frame stiffeners, mounting brackets, and deep structural sections that exceed single-cycle panel bender capacity.

• Battery rack channel and stiffener bending
• Base frame and support bracket forming
• Automatic crowning for long container panels

Next: CNC Turret Punching

Step 05 / 09Battery Energy Storage

Puncionamento de torre CNC

CNC turret punching produces ventilation louvers, cable entry patterns, and repeated mounting holes on BESS doors and side panels — critical for thermal management and high-volume ESS production.

• Vent louver and airflow hole patterns
• Cable gland and connector mounting holes
• Batch punching for standardized cabinet models

Next: Welding

Step 06 / 09Battery Energy Storage

Soldagem

MIG, TIG, and laser welding join cabinet frames, battery rack brackets, and structural reinforcements — delivering the load-bearing strength required for outdoor container and commercial ESS deployments.

• Frame corner and rack bracket welding
• Low-distortion laser weld on visible seams
• Post-weld dimension check before coating

Next: Grinding & Deburring

Step 07 / 09Battery Energy Storage

Grinding & Deburring

All laser-cut edges and weld seams are deburred and ground smooth — essential for gasket sealing surfaces, safe cable routing, and uniform powder coating on outdoor-rated BESS enclosures.

• Burr-free edges on door flange sealing surfaces
• Flush weld grinding on structural joints
• Surface prep before phosphating or coating

Next: Powder Coating

Step 08 / 09Battery Energy Storage

Revestimento em pó

Electrostatic powder coating with curing oven delivers corrosion protection for outdoor BESS containers and commercial ESS cabinets — typically RAL7035 or custom colors with 500+ hour salt-spray rated finishes.

• Outdoor-rated corrosion protection finishes
• Pre-treatment: degreasing and phosphating
• Even film build on deep cabinet sections

Next: Finished BESS Cabinet

Step 09 / 09Battery Energy Storage

Finished BESS Cabinet

Completed battery energy storage cabinets, outdoor container enclosures, and PCS housings pass final inspection — door alignment, vent pattern verification, and dimensional QC before export packing.

• Door gap and gasket flange verification
• Vent pattern and cable entry position check
• Export crate packing for overseas BESS projects
