Which Battery Safety Standards Matter for AGV and AMR Projects in the U.S.?

For a U.S. AGV or AMR project, there is no single safety certificate that covers the battery, vehicle, charging system, transportation, and workplace installation at once. An AGV battery may need to satisfy an industrial battery standard, while the completed vehicle is evaluated under a different safety framework and the lithium battery must separately meet transportation requirements.

For procurement and engineering teams, the practical approach is to separate compliance into four layers: battery safety, vehicle or mobile-platform safety, lithium battery transportation, and workplace installation. IEC 62619, UL 3100, ANSI/ITSDF B56.5, ANSI/A3 R15.08, ISO 3691-4, UN 38.3, UL 583, OSHA requirements, and NFPA standards can all matter, but they do not serve the same purpose.

Which AGV Battery Safety Standards Actually Matter?

The most relevant AGV battery certification depends first on what is being evaluated. A lithium battery pack, an autonomous mobile platform, an automated forklift, and a charging installation have different safety boundaries.

For most industrial projects, procurement teams should ask three questions before requesting any certification:

• What type of AGV or AMR will use the battery?
• Is the requirement for the battery pack, complete vehicle, or installation?
• Will the battery be shipped separately or installed in equipment?

That distinction prevents one of the most common specification mistakes: treating every safety standard as interchangeable.

UL 2271 for Battery Packs

UL 2271 covers electrical energy storage assemblies used in light electric vehicle applications. Its scope includes battery packs, modules, and related energy-storage assemblies used in LEVs. It is therefore a battery-level standard, not a general safety standard for every industrial AGV.

An engineering team should not simply add “UL 2271 required” to every AGV battery RFQ. The application first needs to fit the scope of the standard.

This distinction becomes particularly important with industrial trucks. UL 2271 specifically separates its LEV scope from heavy-duty ride-on industrial trucks, while other UL standards address industrial vehicle applications.

For an AGV project, the better procurement question is:

Which UL standard applies to this exact battery-and-vehicle configuration?

That wording makes the supplier identify the certification scope rather than presenting an unrelated certificate.

IEC 62619 for Industrial Batteries

IEC 62619 is directly relevant to industrial lithium-ion battery systems. The standard establishes safety requirements and tests for secondary lithium cells and batteries used in industrial applications.

Importantly for warehouse automation, IEC explicitly identifies automated guided vehicles (AGVs) as one of the motive applications within the scope of IEC 62619, along with forklift trucks and other industrial vehicles.

This makes IEC 62619 particularly useful when evaluating an industrial AGV battery because it addresses battery safety rather than navigation or vehicle behavior.

For buyers, IEC 62619 documentation can help establish that the battery design has been evaluated against recognized industrial lithium battery safety requirements. It should still be reviewed alongside the standards applicable to the complete AGV or AMR.

UN 38.3 for Lithium Transport

Any lithium AGV battery that enters commercial transportation also needs a separate transportation-safety review.

UN 38.3 refers to the lithium battery tests contained in subsection 38.3 of the United Nations Manual of Tests and Criteria. In the United States, PHMSA identifies these design tests as part of the requirements associated with transporting lithium batteries and also addresses the availability of lithium battery test summaries.

An UN38.3 battery is tested for transportation conditions. That does not mean UN 38.3 certifies the battery for safe operation inside an AGV.

A useful way to distinguish the standards is:

Why Certifications Are Not Interchangeable

The certification printed on an AGV battery should always be interpreted within its scope.

UN 38.3 does not replace industrial battery safety testing. IEC 62619 does not certify the navigation system of an AMR. Likewise, a vehicle-level standard does not automatically demonstrate that every possible replacement battery configuration has independently met the appropriate battery requirements.

This layered approach is especially important because AGVs and AMRs combine several systems:

• battery cells and modules;
• battery management system;
• power distribution;
• drive system;
• charger;
• navigation and sensing;
• safety controls;
• fleet or supervisory controls.

A strong compliance specification therefore identifies which standard applies to each relevant part of the system instead of asking for a generic “safety certified” product.

How UL 3100 Applies to AGV Battery Systems

UL 3100 addresses battery-operated automated mobile platforms used in commercial and industrial environments. Its scope covers platforms used for tasks such as carrying, lifting, product picking, and towing, and includes systems powered by lead-acid or lithium-based batteries.

For an AGV battery project, UL 3100 matters because the battery does not operate independently. It becomes part of an integrated electrical, charging, control, and mobile platform.

Battery and Charger Integration

Battery compatibility should be evaluated as part of the complete power system.

That includes the relationship between:

• battery voltage;
• allowable charge current;
• discharge current;
• charger output;
• BMS limits;
• vehicle controller;
• charging contacts or connectors;
• emergency shutdown behavior.

UL 3100 expressly covers rechargeable battery-powered automated mobile platforms using conductive charging systems, whether charging occurs on board or off board.

For this reason, choosing an AGV battery solely by voltage and amp-hour capacity is not sufficient for a production deployment. The battery, charger, BMS, and vehicle controls need to function as a coordinated system.

BMS and Protective Controls

The BMS is a central safety layer in a lithium AGV battery.

Depending on the battery architecture, protective functions commonly address conditions such as:

• excessive cell voltage;
• low cell voltage;
• excessive current;
• short circuit;
• abnormal temperature;
• charging outside permitted limits.

The exact protection thresholds should come from the battery design, cell requirements, vehicle operating profile, and applicable safety evaluation rather than generic values copied from another battery.

For procurement teams, this means BMS documentation should explain what the protective functions monitor, how the battery responds to abnormal conditions, and how the BMS communicates relevant faults to the vehicle where communication is required.

Off-Board Charger Requirements

Automatic charging is common in AGV and AMR fleets because vehicles can return to charging points between tasks or during scheduled charging windows.

UL 3100 specifically states that portions of the system located off the automated mobile platform, such as an off-board charger, are intended to be installed in accordance with the National Electrical Code, NFPA 70.

This means AGV battery safety does not stop at the battery connector.

Engineering reviews should also consider the charger, branch circuit, charging location, docking arrangement, equipment protection, and installation requirements applicable to the facility.

When UL 583 Applies

Not every battery-powered automated vehicle belongs under UL 3100.

The current UL 3100 scope states that automated mobile platforms covered by the standard are not provided with forks and are not intended to operate as forklifts. Devices with forklift capability are treated as industrial trucks and evaluated under the applicable industrial-truck requirements.

UL 583 covers electric-battery-powered industrial trucks, including forklift trucks, tractors, platform-lift trucks, and other vehicles intended for industrial use. It addresses risks including fire, electric shock, and explosion and also covers power sources intended for those trucks.

This classification should be resolved early in an AGV battery project. An automated cart and an automated forklift may operate in the same warehouse but follow different product-safety paths.

AGV and AMR Safety Standards Beyond Batteries

AGV safety standards extend well beyond battery certification. Mobile robots operate around workers, racks, conveyors, doors, workstations, and other vehicles, so the finished machine needs a broader safety assessment.

In the U.S., ANSI/ITSDF B56.5 and ANSI/A3 R15.08 are particularly important frameworks for different categories of autonomous industrial equipment.

ANSI/ITSDF B56.5 for AGVs

ANSI/ITSDF B56.5 addresses driverless automatic guided industrial vehicles and automated functions of crewed industrial vehicles.

The current B56.5-2024 edition establishes safety requirements associated with the design, operation, and maintenance of powered, unmanned automatic guided industrial vehicles and the systems in which they operate.

This is broader than AGV battery certification. It considers the industrial vehicle as a working system rather than evaluating only its energy source.

A project may therefore have an AGV battery that satisfies an appropriate battery standard while still requiring separate evaluation of vehicle motion, controls, operating conditions, and system safety.

ANSI/A3 R15.08 for AMRs

ANSI/A3 R15.08 focuses on industrial mobile robots.

Part 1 provides safety requirements for the industrial mobile robot itself, while Part 2 addresses IMR systems, applications, and system integration.

This distinction is important for AMR battery safety because the battery is only one risk-control element within a much larger autonomous system.

A compliant deployment also has to consider how the robot is integrated into its workplace, including interactions with people, other machines, charging stations, and material-handling equipment.

ISO 3691-4 System Safety

ISO 3691-4:2023 addresses safety requirements and verification for driverless industrial trucks and their systems.

The standard recognizes driverless industrial trucks as powered trucks designed to operate automatically and considers the operating environment an important part of safe deployment.

However, ISO makes an especially important distinction for battery engineers: requirements for the power source are not covered by ISO 3691-4.

An AGV battery therefore needs to be evaluated under the appropriate battery and electrical safety requirements separately from ISO 3691-4 vehicle-level considerations.

Battery Scope vs. Vehicle Scope

The easiest way to structure an AGV or AMR compliance review is to assign every standard a clear scope.

This framework avoids asking one AGV battery certificate to prove something it was never designed to evaluate.

When OSHA, NFPA, and Shipping Rules Apply

Product standards are only one part of a U.S. deployment. Transportation, facility electrical work, fire safety, and workplace practices can introduce additional requirements.

The applicable rules depend on how the AGV or AMR is classified and where and how the equipment will be operated.

UN 38.3 Test Summaries

For lithium batteries entering transportation, procurement documentation should include the information needed to verify UN 38.3 testing.

PHMSA explains that lithium batteries must undergo the applicable design tests in subsection 38.3 and provides guidance covering the lithium battery test-summary requirement.

When purchasing an AGV battery, buyers should be able to connect the test documentation to the actual battery being supplied rather than receiving an unrelated report for a different pack.

That makes the exact battery identification and test-document reference important parts of supplier qualification.

OSHA 1910.178 Charging Areas

OSHA 29 CFR 1910.178 applies to powered industrial trucks within its defined scope and contains requirements for changing and charging storage batteries.

Among other provisions, OSHA requires battery charging installations for applicable powered industrial trucks to be located in designated areas and addresses fire protection, ventilation, protection of charging equipment, and precautions against open flames, sparks, and electric arcs.

These rules should not automatically be applied to every small AMR simply because it contains an AGV battery or lithium battery. The equipment classification and applicable OSHA provisions should first be established.

NFPA 505 Industrial Truck Safety

NFPA 505 is the Fire Safety Standard for Powered Industrial Trucks Including Type Designations, Areas of Use, Conversions, Maintenance, and Operations. The standard addresses the fire-safety framework for powered industrial trucks and their use in industrial environments.

It becomes particularly relevant when the automated vehicle falls within powered-industrial-truck classifications.

For battery selection, that means the operating environment should be defined before finalizing the AGV battery specification. Vehicle type, facility classification, and fire-safety requirements can affect which equipment standards need to be considered.

NEC Rules for Off-Board Chargers

The National Electrical Code enters the discussion when charging equipment becomes part of the facility electrical installation.

UL 3100 specifically connects off-board portions of an automated mobile platform system, including chargers, with installation under NFPA 70, the National Electrical Code.

For facility engineers, the practical lesson is simple: do not approve the AGV battery first and leave the charging infrastructure until the end of the project.

Battery voltage, charging power, docking design, charger location, electrical installation, and vehicle duty cycle should be reviewed together.

What Procurement Teams Should Require From Battery Suppliers

A good AGV battery RFQ should ask for more than voltage, capacity, chemistry, dimensions, and price. It should establish whether the battery is appropriate for the specific vehicle, charging architecture, operating environment, and compliance path.

The objective is not to collect the largest possible stack of certificates. It is to obtain the right evidence for the right application.

Applicable Standards by Vehicle Type

Start by defining the vehicle.

Is the battery intended for:

• a low-profile transport AGV;
• an autonomous mobile robot;
• a tugger;
• an automated platform;
• an automated forklift;
• another driverless industrial truck?

That classification can change which AGV safety standards and battery requirements apply.

IEC 62619 explicitly includes AGVs within its industrial motive-application scope, while UL 3100 and UL 583 distinguish between automated mobile platforms and industrial trucks.

Certification Scope and Markings

Do not ask only:

“Does this AGV battery have UL or IEC certification?”

Ask which standard applies, which battery configuration was evaluated, and whether the documentation covers the battery that will actually be supplied.

The review should identify details such as:

• battery family or product identification;
• rated voltage;
• applicable configuration;
• relevant certification or test standard;
• associated markings;
• test or certification reference.

This helps prevent a certificate for one configuration from being treated as evidence for an electrically or mechanically different battery pack.

Test Reports and Traceability

Traceability matters because a lithium battery is a system assembled from cells, interconnects, protective components, enclosure hardware, BMS electronics, connectors, and software or firmware where applicable.

Procurement documentation should make it possible to connect the delivered AGV battery with its supporting compliance records.

For transported lithium batteries, the UN 38.3 test-summary documentation should likewise correspond to the applicable battery type.

BMS Safety Documentation

The BMS should not be treated as a feature checklist.

Its protective strategy should match the electrical and operating requirements of the AGV battery, charger, and vehicle.

Useful documentation can identify:

• monitored conditions;
• protection functions;
• fault responses;
• permitted charge conditions;
• permitted discharge conditions;
• temperature monitoring;
• communications required by the vehicle;
• behavior after a protective event.

For OEM projects, this information also helps vehicle engineers define how battery faults interact with the robot controller and fleet operating strategy.

Charger Compatibility Records

Battery and charger compatibility should be documented before deployment.

This becomes especially important for AGV and AMR fleets using automatic docking, opportunity charging, or frequent partial charging because charging is integrated directly into fleet operation.

The supplier should be able to define the electrical charging requirements for the AGV battery, while the system integrator verifies that the charger and vehicle follow those requirements.

For automated mobile platforms evaluated under UL 3100, charging can occur through conductive systems either on or off the vehicle, and off-board system components have separate installation considerations.

Change Control and Requalification

The final procurement requirement is often overlooked: define what happens when the battery changes.

A change in cells, BMS hardware, protective devices, enclosure design, electrical configuration, charger interface, or other safety-relevant components can affect the relationship between the supplied product and its original evaluation.

For long-term AGV programs, suppliers should maintain controlled product documentation and communicate safety-relevant changes rather than allowing a qualified AGV battery specification to drift over successive production batches.

This is especially important when one battery platform will support a fleet for several years. A strong qualification process does more than approve the first sample. It establishes a repeatable battery configuration, traceable documentation, compatible charging requirements, and a clear process for reviewing future changes.
