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

Product Overview

Every prismatic PACK build answers one question at the two ends of the stack: what holds the cells together when they try to move? For modules assembled from 280Ah and 314Ah cells, this sheet metal end plate is that answer. It sits at the extremity of the battery module assembly, closes the compression stack, and converts the swelling force generated during cycling into a controlled, evenly distributed load rather than a point stress on the outermost cell.

The part is formed from 1.2mm SPCC cold rolled steel with tensile strength of >=240Mpa, and it is finished by full integral electrophoresis so that the whole body, faces, inner holes and bending corners, carries an anti-corrosion, anti-rust and insulating layer. Its 174mm (Width) x 188mm (Height) x 19.7mm (Thickness) envelope is matched to 280Ah and 314Ah cells, which means the plate drops into standard large-capacity module designs without adaptor plates or re-drilled fixtures.

Product Features

Made for PACK and Module Assembly Lines

The plate is designed as a production component, not a prototype fitting. Predictable outline dimensions and consistent flatness let it feed stacking and compression stations at line speed, keeping takt time stable across a shift.

1.2mm SPCC Steel Under >=240Mpa Tensile Load

Large-format cells push outward with real force. The steel grade and gauge combination gives the plate the pressure resistance needed to restrain cell swelling and displacement while remaining rigid enough to stay flat across the module face.

Cell Compatibility Across 280Ah and 314Ah

The same plate serves both mainstream capacities, plus similar large-size prismatic lithium cells. PACK planners can standardise on one end plate across multiple module variants instead of carrying separate part numbers.

Crack-Free Forming for Long Module Life

Deep drawing and bending are executed so that every deformed zone stays smooth, burr-free and crack-free, with residual thickness above 90%. A plate that ships without micro-cracks does not become the failure origin after a thousand cycles.

Electrophoresis Insulation in Service Conditions

Modules often live in cabinets, containers or outdoor enclosures where humidity and dust are constant. The integral coating covers the inner holes and bending corners as thoroughly as the flat faces, supporting insulation performance and oxidation resistance over the service life.

Technical Specifications

Application Scope

The plate is aimed squarely at large-capacity prismatic PACK projects: industrial and commercial energy storage power stations, grid energy storage systems, off-grid solar storage equipment and large-scale backup power supplies. In all of these, the end plate is the structural accessory that pairs with 280Ah and 314Ah cells to close the module and protect the stack.

Why Choose Us

Accessory Specialisation

We build supporting structural parts for large-capacity energy storage cells, and we understand the mechanical stress and safety design conventions of industrial modules.

Quality Gate at Every Step

Raw SPCC screening plus in-line checks on stamping, stretching, bending and electrophoresis keep defects out before shipment.

Safety Built Into the Form

Crack-free integral forming removes the structural weak points that later turn into module faults, while electrophoresis handles corrosion and insulation duty.

Supply You Can Plan Around

Standard plates are stocked, automated lines support bulk volume, and the quoted cycle is 10-15 working days with factory-direct pricing.

Drawing-Based Customisation

Where a module needs a different size, thickness or surface treatment, production follows customer drawings rather than forcing a catalogue part.
