VDA 355 Module Applications Beyond the Passenger Car
Short answer: VDA 355 modules — standardised prismatic battery modules measuring approximately 355 × 151 × 108 mm — are suited to applications beyond the passenger car: electric boats, AGVs, forklifts and industrial machinery. Their mechanical standardisation and well-documented electrical interfaces make them practical for integrators who need a proven cell-to-module foundation without committing to a proprietary design.
The passenger car is where the VDA 355 format was standardised, but the same module envelope serves shipbuilders, AGV manufacturers, forklift OEMs and machinery builders just as well. Each application class imposes different environmental, cycling and certification constraints — and understanding those differences is where pack integration decisions are made.
Why a standardised automotive module works in other markets
The advantages of the VDA 355 format trace back to one decision: decoupling the mechanical pack architecture from a single cell supplier. The module's fixed envelope — 355 mm long, with defined busbar positions and a flat cooling surface — means an integrator can design a pack structure once and source cells from more than one qualified manufacturer. That supply-chain flexibility, originally engineered for automotive procurement, transfers directly to marine, industrial and off-highway programmes where long product lifetimes make single-source dependency a serious risk.
The modules are rated for vehicle duty: the three VDA 355 modules in the Avantis Energy catalogue are rated at 1,500–2,000 cycles, at 80 % or 95 % depth of discharge (DoD) depending on the module. That figure fits the utilisation profile of most industrial vehicles and many marine applications. It does not fit high-cycle stationary storage, where purpose-built ESS modules rated at 8,000 cycles or more at 80 % DoD are the appropriate starting point. The two product families must not be confused in a system specification.
Application by application
Electric and hybrid boats
Marine integration of automotive battery modules is growing, driven by harbour emissions regulations and the electrification of short-sea and inland waterway vessels. The VDA 355 module's compact prismatic form fits efficiently into hull voids and below-deck compartments where cylindrical or pouch cells are harder to manage mechanically.
The critical difference from a car pack is the environment. Salt air, condensation and hull vibration impose demands on the enclosure, not on the module itself. Ingress protection (IP rating) is a property of the battery housing the integrator builds around the modules; it is not a module-level specification. Thermal management also shifts: marine packs may use liquid cooling drawn from the vessel's raw-water circuit, or air cooling where ambient temperatures are moderate. Either approach can interface with the module's flat base, which serves as the cooling surface.
Classification societies — Bureau Veritas, DNV, Lloyd's Register and others — set the certification framework for shipboard energy storage. Those bodies publish their own rules for battery systems on vessels; meeting them is the responsibility of the system integrator and the shipyard. The module format itself does not carry marine type approval; compliance is established at the system level.
Chemistry is a real choice on board. Weight and volume count on a vessel, which favours the energy density of NCM; LFP's thermal stability weighs heavily in an enclosed hull. LFP versus NCM in a VDA 355 module sets out the trade-off.
Automated guided vehicles (AGVs)
AGVs cycle frequently and predictably, with shallow individual cycles and opportunity charging during loading or unloading. What counts for the cycle budget is the number of equivalent full cycles those partial events add up to per year — calculate that first, then compare it with the module's rated cycle life. A compact, energy-dense module also leaves more room in a small chassis for payload and mechanics.
The VDA 355 module's defined mechanical envelope simplifies AGV chassis design. A standard module tray can be replicated across a fleet without redesigning around each cell generation. The cell supervision circuit (CSC) scope varies by module and project; the integrator defines the BMS architecture separately and should not assume a given slave board is included.
Vibration in a warehouse AGV is low-frequency and low-amplitude compared with an off-road vehicle. Pack-level shock and vibration testing per IEC 62619 or UN 38.3 remains the integrator's obligation. The IEC 62619 standard covers safety requirements for secondary lithium cells and batteries for use in industrial applications and is the applicable framework for AGV battery systems.
Industrial vehicles: forklifts, reach stackers and terminal tractors
Lift trucks and port equipment run multi-shift operations with opportunity charging at every rest stop. Energy throughput per day is high, and the pack must tolerate the vibration and shock of uneven yard surfaces. At 400 equivalent full cycles a year, a five-year service life adds up to 2,000 cycles, the upper end of what the VDA 355 modules in the catalogue are rated for.
Integrators working in this segment should size the pack conservatively — using 80 % DoD as the operating boundary rather than pushing deeper — and confirm the module's rated cycle life against the expected daily cycle count before committing. The EU Battery Regulation 2023/1542 introduces durability and cycle-life declaration requirements for industrial batteries; integrators placing battery systems on the European market should confirm their system-level compliance obligations under that regulation.
Mining and construction machinery
Off-highway equipment presents the most demanding mechanical environment in this group. Shock loads, dust, extreme temperature ranges and long service intervals combine to raise the bar on pack design. The VDA 355 module itself is engineered for automotive duty, which includes defined shock and vibration limits; the pack housing, mounting isolation and thermal management system must address everything the module specification does not cover.
Cooling is particularly relevant: construction machinery may work through a frosty morning and a hot afternoon on the same site. The module's flat cooling interface supports liquid-cooled plates, which is the standard approach in duty cycles that generate sustained heat. Battery heating for cold-start is a separate design element, typically implemented at pack level.
Avantis Energy supplies VDA and MEB battery modules qualified through factory-level inspection and lot-by-lot documentation, which supports the traceability requirements that arise in regulated industrial markets.
Format comparison across application classes
| Application | Cycle profile | Key environmental factor | What the integrator adds | Certification framework |
|---|---|---|---|---|
| Electric boat | Moderate cycles, variable depth | Salt air, condensation | Sealed enclosure (IP), marine cooling loop | Classification society rules (DNV, BV, LR) |
| AGV | Frequent shallow cycles, opportunity charge | Low vibration, indoor temperature | Compact tray, BMS for fleet charging | IEC 62619, UN 38.3 |
| Forklift / terminal tractor | High daily throughput, opportunity charge | Moderate vibration, outdoor exposure | Robust mounting, cycle budget check | EU Battery Regulation, IEC 62619 |
| Mining / construction | Irregular, deep discharge possible | High shock, dust, wide temperature range | Shock isolation, heating and liquid cooling | Application-specific, national regulations |
What stays the same and what the integrator must own
Across all four application classes, the module geometry, busbar layout and cooling interface remain constant — that is the value of the standardised format. What the integrator must design specifically for each application is the enclosure (including IP class), the thermal management system, the BMS architecture, the mounting and isolation strategy, and the system-level certification path.
The module's cell configuration — 1P4S, 2P6S or 3P4S in LFP or NCM — determines nominal voltage and energy content. Selecting the right configuration for the application's voltage bus and energy requirement is the first engineering decision; VDA 355 module dimensions and specifications provides the dimensional and electrical reference for that calculation.

If you are sizing a pack for a boat, AGV, or industrial vehicle, bring the application's voltage, energy and environmental requirements to a technical conversation. Discuss your pack requirements with Avantis Energy or review the available VDA and MEB module configurations as a starting point.
Frequently asked questions
What are the main VDA 355 module applications outside passenger cars?
VDA 355 modules are used in electric and hybrid boats, automated guided vehicles (AGVs), industrial lift trucks, port equipment and off-highway construction or mining machinery. In each case the standardised mechanical envelope simplifies pack design, while the enclosure, thermal system and certification path are adapted for the specific application.
Should a boat or AGV use LFP or NCM VDA 355 modules?
It depends on what the application is short of. NCM offers higher energy density, which counts where space and weight are tight, as on a vessel or in a compact AGV chassis. LFP offers greater thermal stability, which counts in an enclosed hull. Either way the enclosure, BMS and thermal system carry the safety case at system level.
Does a VDA 355 module carry marine or industrial type approval?
No. The module format does not carry system-level type approval. Classification society approval for a marine installation — and industrial certification under frameworks such as IEC 62619 — is obtained at the battery system level by the integrator or system builder, not at the module level.
How many cycles can a VDA 355 module deliver in an AGV application?
VDA 355 modules are rated for vehicle duty: the three modules in the Avantis Energy catalogue are rated at 1,500–2,000 cycles, at 80 % or 95 % depth of discharge depending on the module. For AGVs with shallow opportunity-charge cycles this budget is usually sufficient over a normal service life, but the integrator should verify cycle count against the application's daily throughput before finalising the specification.
Is a VDA 355 module suitable for stationary energy storage?
Not as the primary building block. Stationary storage with high daily cycling requires purpose-built ESS modules rated at 8,000 cycles or more at 80 % DoD. VDA 355 modules are engineered for vehicle duty and should not be specified as the standard choice for grid-scale or commercial stationary packs where cycle life is the dominant design driver.
