What Is a VDA355 Battery Module?

As electric vehicles and battery energy storage systems continue to evolve, standardized battery module designs have become increasingly important. Among these standards, the VDA355 battery module is one of the most widely recognized formats used throughout the automotive industry.

Rather than referring to a specific battery model, VDA355 defines a standardized module size that enables manufacturers to design battery systems with greater compatibility, easier integration, and improved production efficiency.

What Does VDA355 Mean?

VDA355 is a battery module standard originally developed by the German Association of the Automotive Industry (VDA). The name “355” refers to the approximate module length of 355 mm.

Typical external dimensions are approximately:

• Length: 355 mm
• Width: 151 mm
• Height: 108 mm

Although small dimensional differences may exist between manufacturers, most VDA355 modules follow this standardized footprint, allowing system designers to interchange modules more easily.

Common VDA355 Configurations

Different battery cell capacities can be arranged into various series and parallel configurations while maintaining the same external dimensions.

Typical configurations include:

These configurations provide flexibility for different vehicle architectures while keeping manufacturing standardized.

Compatible Battery Cells

VDA355 modules are commonly assembled using prismatic NMC battery cells from manufacturers such as CALB, SVOLT, REPT, EVE Energy, and Gotion High-Tech.

Depending on project requirements, battery capacities may range from approximately 50Ah to over 120Ah while maintaining the same module dimensions.

Advantages of VDA355 Modules

The standardized design offers several engineering advantages:

• Simplified battery pack development
• Higher manufacturing efficiency
• Better compatibility across platforms
• Easier maintenance and replacement
• Mature automotive supply chain support
• Flexible voltage and capacity combinations

These benefits have made VDA355 one of the preferred module formats for electric vehicles, commercial vehicles, AGVs, forklifts, marine applications, and stationary energy storage.

Typical Applications

VDA355 battery modules are widely used in:

• Electric passenger vehicles
• Low-speed electric vehicles
• Commercial EV platforms
• Automated guided vehicles (AGVs)
• Electric forklifts
• Marine battery systems
• Residential and commercial ESS

Conclusion

The VDA355 battery module has become an industry-standard platform that balances standardization with design flexibility. Its consistent dimensions, multiple electrical configurations, and compatibility with various battery cells make it a practical choice for modern battery system development.

As battery technology continues to advance, VDA355 modules remain an important building block for scalable EV and energy storage solutions.
