Compliance & Safety

Global Certifications

American BMS meets the most rigorous international safety, performance, and transport standards for battery management systems. Our commitment to compliance ensures safe, reliable, and globally deployable energy storage solutions.

UN

UN 38.3

United Nations Manual of Tests and Criteria, Section 38.3

What It Covers

UN 38.3 is the internationally recognized standard for the safe transport of lithium metal and lithium-ion batteries. It mandates a series of eight rigorous tests that simulate conditions batteries may encounter during transportation.

Test Requirements

  • T.1 Altitude Simulation Low-pressure conditions simulating air transport at 15,000m
  • T.2 Thermal Test Rapid temperature cycling between 75C and -40C
  • T.3 Vibration Sinusoidal vibration simulating transport conditions
  • T.4 Shock Half-sine shock pulses in multiple orientations
  • T.5 External Short Circuit Short circuit at 55C with less than 0.1 ohm resistance
  • T.6 Impact / Crush Mechanical crush or impact testing
  • T.7 Overcharge Charging at twice the recommended current
  • T.8 Forced Discharge Forced discharge with external power source

Why It Matters for BMS

The BMS plays a critical role in ensuring batteries pass UN 38.3 by providing protection against overcharge, over-discharge, short circuit, and thermal events. Our BMS firmware includes specific safety protocols that activate during the extreme conditions tested under UN 38.3.

American BMS Advantage

Our integrated approach means the BMS is tested as part of the complete battery system, not as an afterthought. This ensures seamless protection coordination between hardware, firmware, and Digital DNA analytics.

UL

UL 1973

Standard for Batteries for Use in Stationary, Vehicle Auxiliary Power, and Light Electric Rail Applications

What It Covers

UL 1973 evaluates batteries intended for use in stationary applications (such as residential and commercial energy storage), vehicle auxiliary power, and light electric rail. It assesses electrical, mechanical, and environmental safety.

Key Test Categories

  • Electrical Tests Overcharge, over-discharge, short circuit protection validation
  • Mechanical Tests Drop, vibration, and mechanical shock resistance
  • Environmental Tests Temperature cycling, humidity, and altitude exposure
  • Thermal Runaway Assessment of cell-to-cell propagation resistance
  • Enclosure & Markings Fire resistance, IP rating, and safety labeling

Why It Matters for BMS

UL 1973 specifically evaluates the BMS as a safety-critical component. The BMS must demonstrate reliable overcharge/over-discharge protection, thermal management, and fault detection. Our system exceeds these requirements through multi-layered hardware and software safety mechanisms.

American BMS Advantage

Our redundant safety architecture includes independent hardware protection circuits that operate even if the main BMS processor fails, exceeding the single-point-of-failure requirements in UL 1973.

UL

UL 9540

Standard for Energy Storage Systems and Equipment

What It Covers

UL 9540 is the comprehensive safety standard for complete energy storage systems (ESS). It covers the entire system including batteries, BMS, power conversion, thermal management, and integrated controls. This is the go-to standard for residential and commercial ESS installations.

Key Requirements

  • System-Level Safety Complete ESS evaluation including all subsystems
  • UL 9540A Testing Thermal runaway fire propagation evaluation
  • Functional Safety BMS fault response and fail-safe verification
  • Grid Integration Safe interconnection with utility grid systems
  • Installation Safety Clearance, ventilation, and fire suppression requirements

Why It Matters for BMS

The BMS is the nerve center of any UL 9540-listed system. It must coordinate thermal management, fault isolation, and emergency shutdown procedures. Our BMS provides the intelligence layer that enables systems to meet the stringent UL 9540A thermal runaway propagation requirements.

American BMS Advantage

Our Digital DNA platform provides continuous monitoring that goes beyond UL 9540 requirements, offering predictive safety intervention before fault conditions develop into safety events.

IEC

IEC 62619

Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications

What It Covers

IEC 62619 is the international safety standard for lithium batteries used in industrial applications including energy storage, telecom backup, UPS systems, and material handling equipment. It is widely recognized across European and Asian markets.

Key Test Areas

  • Electrical Safety Overcharge, forced discharge, and external short circuit
  • Thermal Safety Thermal abuse, propagation resistance testing
  • Mechanical Safety Crush, impact, and vibration testing
  • BMS Functional Safety Protection circuit verification and fail-safe testing
  • Environmental Testing Temperature extremes and humidity exposure

Why It Matters for BMS

IEC 62619 explicitly requires BMS functional safety testing, making it a cornerstone certification for any BMS targeting industrial energy storage. The standard validates that the BMS correctly manages cell protection, thermal response, and fault conditions.

American BMS Advantage

Our BMS architecture is designed from the ground up for IEC 62619 compliance, with dual-redundant measurement circuits and hardware-level protection that operates independently of the main control software.

IEC

IEC 62133

Safety Requirements for Portable Sealed Secondary Lithium Cells and Batteries

What It Covers

IEC 62133 addresses safety requirements for portable sealed secondary lithium cells and batteries used in portable applications. Part 2 specifically covers lithium systems and is a prerequisite for many international market certifications.

Key Test Areas

  • Continuous Charging Extended charge at maximum voltage and current
  • External Short Circuit Short circuit at ambient and elevated temperatures
  • Free Fall / Drop Mechanical shock from specified heights
  • Thermal Abuse Exposure to elevated temperatures (130C)
  • Crush & Impact Mechanical deformation testing

Why It Matters for BMS

For portable and modular battery systems, IEC 62133 compliance ensures the BMS provides adequate protection in consumer-accessible scenarios. The BMS must prevent unsafe conditions even when subjected to misuse or environmental extremes.

American BMS Advantage

Our scalable BMS platform supports configurations from portable modules to utility-scale systems, maintaining IEC 62133 compliance at the cell level while scaling up to meet UL and UN requirements at the system level.
