NMC Chemistry 2P12S · 44.04 V Nominal 6.87 kWh · 156 Ah 222 Wh/kg VDA 590 Brand New · Direct from OEM ⬡ VDA 590 Compliant Form Factor This module conforms to the VDA 590 dimensional standard (590 × 225 × 108 mm) established by the Verband der Automobilindustrie (German Association of the Automotive Industry). The VDA 590 format, also known as the MEB 590 standard, was developed alongside Volkswagen's Modular Electric Drive (MEB) platform and has become a widely adopted industry benchmark for large-format battery modules across OEMs and pack integrators worldwide. VDA 590 compliance means this module shares standardized external dimensions, mounting interfaces, and thermal coupling surfaces with other VDA 590 class modules on the market. This simplifies mechanical integration, enables multi-source procurement strategies, and allows drop-in compatibility with pack enclosures and cold plates designed to the VDA 590 envelope. Overview The LG E78-2P12S module delivers high specific energy and strong power capability in a compact, industry-standard enclosure, making it an ideal building block for electric vehicle battery packs, renewable energy storage systems, and industrial backup power. The 2P12S layout pairs two cells in parallel across twelve series groups, combining fast charging with a wide operating temperature range and a large, flat cooling interface for straightforward pack-level thermal design. Built on LG Energy Solution prismatic NMC cell technology, this module is widely used in OEM traction packs and stationary storage systems worldwide. Its VDA 590 compliant mechanical envelope and M6 power terminals make it easy to integrate into custom series/parallel pack architectures with industry-standard BMS controllers and existing VDA 590 pack designs.

Integration Notes VDA 590 envelope: module dimensions conform to the VDA 590 standard (590 × 225 × 108 mm), enabling compatibility with pack enclosures, cold plates, and structural housings designed to this widely adopted form factor. Cooling surface: indirect cooling via bottom face; target interface area of ~500 mm × 215.4 mm, clean, flat, and thermally coupled to cold plate or heat sink. Module clearances: allow +10 mm minimum (standard) or +15 mm (with planned swelling margin) between modules for cell expansion and mechanical tolerance. Power terminals: M6 studs; typical torque 9 Nm ±10% on clean, flat copper or tinned lugs. Environmental sealing: module is not sealed; ensure pack-level IP-rated enclosure to prevent condensation and ingress. BMS compatibility: integrates well with the Orion BMS family (Standard, 02, or JR2) depending on pack voltage and application requirements. Evolve Electrics stocks all Orion BMS variants.

Earlier 7.4 V references in some documentation apply to smaller 2S sub-modules, not the full 2P12S assembly. Is this module VDA 590 compliant? Yes. The LG E78-2P12S conforms to the VDA 590 dimensional standard (590 × 225 × 108 mm), established by the German Association of the Automotive Industry. This is the same form factor used across Volkswagen's MEB platform and adopted by numerous other OEMs and pack integrators worldwide. VDA 590 compliance ensures drop-in compatibility with pack enclosures and cold plates designed to this standard envelope. Which BMS is recommended for use with this module? We recommend the Orion BMS family (Standard, 02, or JR2) depending on your pack architecture and total series cell count. Evolve Electrics is an authorized Orion BMS distributor and can help you select the right unit for your application. Is liquid cooling required? Indirect cooling via the bottom surface is strongly recommended for sustained power output, optimal cycle life, and operation at higher C-rates. The module's flat bottom face is designed for thermal coupling to a cold plate or heat exchanger. How many modules do I need for a 48 V system? A single E78-2P12S module provides 44.04 V nominal, which works well in nominal 48 V architectures. For higher voltage systems, connect modules in series. For example, two modules in series yield ~88 V and four yield ~176 V. Contact our engineering team for pack design guidance. Can this module be used for energy storage (ESS)? Yes. The E78-2P12S is widely used in residential and commercial energy storage systems, solar buffering, and microgrid applications. Its high cycle life, wide temperature range, and scalable architecture make it well suited for stationary storage deployments. Is a 3D CAD model available? Yes. A STEP file is available for download in the Downloads & Resources section above. Use it for mechanical integration, enclosure design, and pack layout planning. What certifications does this module support? The module supports UL, CE, and UN38.3 certification at the pack level when properly integrated with a BMS, enclosure, and safety systems. Evolve Electrics can advise on certification pathways for your specific application.
