What is a VDA355 Battery Module？
What is a VDA355 Battery Module
1. Core Definition
VDA355 is a standardized lithium-ion battery module specification issued by VDA (Verband der Automobilindustrie / German Association of the Automotive Industry).
The number "355" stands for its fixed standard length: 355 mm
Unified outer dimension: 355 mm (L) × 151 mm (W) × 108 mm (H)
It was originally developed for Volkswagen’s MEB electric vehicle platform and later adopted as a global universal automotive battery standard by most OEMs and cell manufacturers (CALB, CATL, A123, etc.)
2. Internal Cell & Electrical Configurations
It uses standard square automotive cells (base cell size: 148×90mm) with flexible series-parallel layouts to match different voltage/capacity demands:
| Common Wiring | Cell Layout | Typical Nominal Voltage | Typical Capacity |
| 1P12S | 12 cells in series | ~44.4V (NCM) | ~50–52Ah |
| 2P6S | 6 cells series, 2 parallel | ~22.2V | ~100–106Ah |
| 3P4S | 4 cells series, 3 parallel | ~14.8V | ~150–174Ah |
| 4P3S | 3 cells series, 4 parallel | ~11.1V | ~200–220Ah |
Compatible cathode chemistries:
NCM / NCA (high energy density for passenger EVs)
LFP (low cost, long cycle life for commercial vehicles & energy storage)
LTO (ultra-long cycle, fast charging for industrial equipment)
3. Key Standardized Design Features
Interchangeability
Uniform mounting holes, terminal positions, cooling channel interfaces, and BMS sampling sockets. Modules from different brands can be swapped in the same battery pack, cutting supply chain risks and after-sales maintenance costs.
Integrated Safety & Thermal Design
Built-in liquid cooling channels, insulation layers, pressure relief valves, and FPC voltage/temperature sampling boards, complying with VDA automotive safety and thermal runaway control rules.
Compact & High Integration
Aluminum alloy housing for lightweight heat dissipation; single module weight ~11-12kg, energy range ~1.7-2.3 kWh per unit.
4. Main Application Scenarios
New Energy Vehicles (core use)
Pure electric passenger cars & PHEVs (VW MEB platform, mainstream European/Chinese EV brands)
Light commercial EVs, electric buses, mining machinery
Stationary Energy Storage
Household energy storage, industrial UPS, solar storage systems
Special Equipment
Electric ships, AGVs forklifts, airport ground vehicles, off-road machinery
5. Core Advantages of VDA355 Standard
Lower manufacturing cost: Mass automated assembly enabled by unified sizing
Simplified vehicle pack design: OEMs do not need custom module molds
Flexible capacity expansion: Stack multiple modules in series/parallel to build high-voltage battery packs
Global supply compatibility: Universal standard shared by European, Chinese, Korean battery suppliers
How to distinguish a VDA355 Battery Module is New or used?
New vs Used VDA355 Module
1. Visual Inspection
New: Scratch-free aluminum shell; shiny unburnt busbars; intact torque paint marks on screws; dry cooling ports; complete factory protective film; no re-welding or re-gluing.
Used: Polished scratches, darkened busbars; misaligned screw paint marks; re-taped terminals; coolant residue at cooling ports.
2. Label & Serial Number Check
New: Sharp laser engraving without sanding; consistent production batch/date for module and internal cells.
Used: Sanded original codes with blurry reprinted labels; cell production dates much earlier than module label.
3. Electrical Test
Cell voltage difference: New NCM ＜20mV, LFP ＜30mV; Used ＞50mV
Internal resistance: New cells fluctuate within 5%; Used cells over 15% higher
Capacity: New ≥98% rated capacity; Used mostly below 90%
