In today’s fast-growing electric vehicle (EV) and battery energy storage system (BESS) markets, standardized battery modules have become essential for scalability, cost efficiency, and interoperability. A VDA355 Module Factory specializes in producing VDA355 lithium-ion battery modules — compact, high-performance building blocks that meet the dimensional standards popularized by the German automotive industry. These factories enable manufacturers, integrators, and OEMs to build reliable battery packs faster and more economically while maintaining automotive-grade quality.
Whether you are sourcing modules for passenger EVs, commercial vehicles, stationary storage, marine applications, or mining equipment, understanding what a professional VDA355 module factory delivers is key to making informed decisions.
What Is the VDA355 Battery Module Standard?
The VDA355 module refers to a widely adopted standardized lithium-ion battery module size originally influenced by recommendations from the German Association of the Automotive Industry (VDA) and popularized through early Volkswagen platforms. The “355” designation comes from the module’s approximate length of 355 mm.
Typical dimensions (with minor manufacturer tolerances):
- Length: 355 mm (±1 mm)
- Width: 151–152 mm
- Height: 108–108.5 mm
This compact form factor allows flexible series-parallel configurations in battery packs while ensuring mechanical compatibility across different vehicle platforms and energy storage systems. Although Volkswagen’s later MEB platform shifted toward larger modules (such as ~590 mm variants) for improved energy density in some applications, the VDA355 standard remains highly popular — especially in China and among global suppliers — due to its versatility, proven reliability, and ease of integration.
Key Specifications of VDA355 Modules from Leading Factories
Professional VDA355 module factories produce modules in multiple chemistries (NCM/NMC and LFP) and electrical configurations (commonly 1P4S, 2P6S, and others). Here is a representative example from a major supplier:

Inside a Modern VDA355 Module Factory: Manufacturing Excellence
A reputable VDA355 Module Factory combines precision engineering, automation, and rigorous quality systems to deliver consistent, high-reliability modules at scale. Production typically includes:
- Cell Incoming Inspection & Sorting — Prismatic cells undergo 100% testing for capacity, internal resistance, and safety. Cells are matched for optimal module performance.
- Module Framing & Cell Stacking — Precision aluminum or composite frames ensure exact VDA355 outer dimensions and structural integrity under vibration and crash conditions.
- Busbar Welding & Electrical Integration — Automated laser or ultrasonic welding creates low-resistance, high-current connections.
- BMS Integration — Advanced Battery Management Systems with balancing, thermal monitoring, and communication protocols (CAN, etc.) are installed and calibrated.
- Thermal Management & Sealing — Options for air or liquid cooling interfaces; modules are sealed for IP-rated protection.
- End-of-Line (EOL) Testing — Comprehensive validation including capacity verification, insulation resistance, high-pot testing, leak testing, and functional safety checks.
- Traceability & Quality Documentation — Full batch traceability supporting IATF 16949, ISO 9001, and automotive customer requirements.
These automated lines (often running at high throughput) minimize human error and ensure every module leaving the factory meets the tight tolerances required for seamless pack assembly.
