Resonate Testing supports IEC 62619 battery safety testing for industrial lithium-ion batteries used in Battery Energy Storage Systems (BESS), industrial vehicles, marine, rail, UPS, telecom backup and critical power applications.
Testing is carried out at Resonate Testing’s purpose-built facility in Newry, Northern Ireland, providing practical access for UK and European manufacturers preparing batteries for safety assessment, certification routes and market readiness.
IEC 62619 is the internationally recognised safety standard for industrial lithium-ion batteries. It applies to rechargeable lithium battery cells and systems used in applications such as BESS, UPS, telecom backup power, industrial vehicles, marine and rail systems. The standard assesses battery safety under electrical, mechanical and thermal fault conditions.

Ready to plan IEC 62619 battery testing? Send your cell or battery details, datasheet, target standard, sample condition and acceptance criteria for engineer review.
IEC 62619 testing often requires an early review of the battery design, intended application, cell chemistry, battery management system (BMS), sample condition, charge state and safety requirements.
Share your battery specification, drawings, chemistry, capacity, voltage, protection circuitry, intended use, sample quantity and certification requirements. Resonate Testing can review the proposed IEC 62619 test programme before quotation.
A common misconception is that compliance at cell level automatically covers an entire battery system. Under IEC 62619, safety requirements apply to the complete industrial battery application, including the cells, battery management system (BMS), protective devices, electrical connections and enclosure.
Battery systems often incorporate additional safety functions and control features that can influence overall safety performance. Changes in design, integration, capacity, configuration or protection circuitry can affect compliance and may require further assessment.
Failure to demonstrate compliance with IEC 62619 can result in delays during product approval, difficulties accessing global markets, increased project risk and challenges meeting customer, regulatory or contractual safety requirements.
| Standard / Guidance | Primary Focus | Typical Relevance |
|---|---|---|
| BESS and renewable energy storage | Stationary energy storage safety and performance | Stationary storage for grid, commercial and renewable energy systems |
| Telecom, UPS and emergency power | Backup and standby power reliability | Backup and critical power systems where continuity matters |
| Industrial vehicles | Motive power battery safety and durability | Forklifts, AGVs, AMRs and other battery-powered equipment |
| Marine and rail | Transport battery safety and environmental resilience | Propulsion, auxiliary power and onboard energy storage systems |
Test programmes can be shaped around the applicable battery type, risk profile and certification objective. Resonate Testing can support the core IEC 62619 safety test areas and related investigation work.

Cell or battery datasheet, drawings and product application
Target standard, customer specification and acceptance criteria
Chemistry, nominal voltage, capacity, configuration and protection circuitry
Sample quantity, condition, state of charge and preconditioning needs
Required safety, performance, abuse, environmental or transport tests
Temperature, voltage, visual or customer instrumentation requirements
Enclosure, venting, insulation, BMS and containment features
Hazardous material, stored energy, shipping and emergency response information
A mechanical safety test used to assess battery performance following accidental handling impacts.
A safety function that interrupts current flow when current exceeds safe operating limits.
The available capacity of a battery expressed as a percentage of its rated capacity.
A safety device or electronic function designed to prevent hazardous conditions such as overcharge, overcurrent or overheating.
The spread of thermal runaway or failure from one cell or module to adjacent cells or modules within a battery system.
An unintended low-resistance connection between battery terminals that can produce excessive current and heat.
Two or more secondary cells connected together to provide electrical energy.
A rechargeable electrochemical cell capable of being charged and discharged repeatedly
An assembly of one or more battery packs, together with associated control, monitoring and protection equipment.
A group of modules or cells connected together and equipped with protection devices and electrical connections.
A collection of cells assembled into a mechanical and electrical unit that forms part of a battery pack.
For projects that need deeper evidence on battery behaviour under severe or abnormal conditions, testing can include additional abuse and investigation methods.
These tests help engineering teams understand how cells, modules or systems respond to fault conditions and how risk controls perform during a severe event.
Many battery programmes require more than one standard. Resonate Testing can help identify the relevant test route and support related requirements across industrial, transport and aviation-linked battery applications.
Send your battery specification, drawings, intended application and any certification requirements for review. The engineering team can advise on the most suitable test approach, programme readiness and supporting standards.
