280Ah / 314Ah Prismatic Battery Sheet Metal End Plate | SPCC Electrophoresis End Plate for Energy Storage PACK

Product Overview

Two material decisions define this part: which steel, and what covers it. The base is 1.2mm SPCC cold rolled steel, a grade chosen for consistent gauge, workability and a tensile strength of >=240Mpa that stays stable from coil to coil. The cover is a full integral electrophoresis coating, black, applied to the finished geometry so that the corrosion barrier exists on the flat faces, inside the holes and around the bending corners at the same time.

Between those two decisions sits the forming step, which determines whether the material actually performs as specified. Precision deep drawing and bending leave the deformed zones crack-free and burr-free, and residual thickness is kept above 90% of the original plate. The resulting component measures 174mm (Width) x 188mm (Height) x 19.7mm (Thickness) and is compatible with 280Ah, 314Ah and similar large-size prismatic lithium cells, one part number covering the mainstream large-format capacities used in energy storage modules. The black finish also makes coating coverage easy to verify by eye before a plate is released to the stacking station, which shortens the gap between inspection and assembly.

Product Features

SPCC Cold Rolled Steel at 1.2mm

Cold rolled SPCC gives a flat, uniform substrate with predictable forming behaviour. At 1.2mm, the section is thick enough to resist deformation and extrusion stress generated by large cells while staying within normal module envelope limits.

Tensile Strength >=240Mpa, Verified Not Assumed

Incoming screening keeps the plate above the >=240Mpa threshold, so the pressure-bearing capacity quoted in the specification is the capacity the shipped part delivers.

Black Full-Body Electrophoresis Coating

Electrophoresis deposits evenly, including into inner holes and bending corners where spray coatings thin out. The result covers anti-rust, anti-corrosion, weather resistance and insulation duty in a single treatment.

Compatibility With 280Ah and 314Ah Cells

The 174 x 188 x 19.7mm footprint is matched to these two capacities and to similar large-size prismatic cells. Designers can carry the same end plate across module variants rather than qualifying a second part.

Forming That Preserves Material Integrity

Crack-free edges and >=90% residual thickness mean the mechanical properties of the steel survive the manufacturing process, so the plate behaves like 1.2mm SPCC and not like a thinned-out approximation of it.

Technical Specifications

Application Scope

The material set of SPCC steel plus integral electrophoresis is intended for high-power energy storage environments: industrial and commercial storage stations, grid storage systems, off-grid solar storage equipment and large-scale backup supplies. In these settings the coating carries the corrosion and insulation workload, which is why full coverage rather than partial coating matters.

Why Choose Us

Material Control From the Coil

Qualified SPCC steel with stable tensile strength is the starting point; nothing enters production without meeting the grade.

Coating Quality as a Specification

Electrophoresis coverage is inspected, not left to chance, because insulation performance depends on complete deposition.

Long Experience in Energy Storage Parts

Years of producing structural accessories for large-capacity cells means we know how module stress and safety requirements translate into a sheet metal design.

Cost and Availability

Stocked standard plates, automated precision lines, bulk-order support and factory-direct pricing keep total procurement cost down.

Custom Material Options

Non-standard sizes, thicknesses and surface treatments are available to match your drawings and module design.
