EV battery testing evaluates the safety, performance, durability and failure behaviour of electric vehicle battery systems under defined operating and fault conditions.
Testing may be performed at cell, module, pack or complete vehicle subsystem level depending on the application and compliance requirements. Programmes often combine environmental, mechanical, electrical and abuse testing to assess how battery systems perform throughout their intended service life.
The objective is simple: to verify that batteries remain safe, reliable and fit for purpose when exposed to the conditions likely to be encountered during transportation, installation, operation and foreseeable misuse.

The consequences of battery failure can be significant, ranging from operational disruption and financial loss to serious safety risks. Manufacturers must therefore demonstrate that batteries can withstand mechanical damage, thermal events, electrical faults and environmental stresses without creating unacceptable hazards.
Effective EV battery testing helps organisations:
Testing also provides valuable engineering data that can be used to improve battery design, optimise performance and enhance long-term reliability.
Resonate Testing provides independent EV battery testing services to support product development, design validation, transportation approval, certification programmes and market access activities. Our battery testing capabilities help manufacturers, integrators and developers generate the evidence required to demonstrate battery safety, durability and compliance throughout the product lifecycle.
UNECE Regulation No. 100 (R100) establishes requirements relating to the safety of rechargeable energy storage systems used within electric vehicles.
The regulation is widely recognised across international automotive markets and addresses key aspects of battery safety, durability and protection. Requirements include assessments of battery behaviour under mechanical, thermal and electrical stresses, helping manufacturers demonstrate that battery systems remain safe throughout their operational life.
Resonate Testing can support organisations developing compliance evidence for vehicle certification programmes aligned with UNECE R100 requirements.

UNECE Regulation No. 136 specifies safety requirements for vehicles powered by rechargeable electric powertrains in the L-category vehicle sector.
The regulation is particularly relevant for electric motorcycles, scooters, quadricycles and other lightweight electric vehicle platforms. Similar to UNECE R100, it focuses on battery system safety, electrical protection and rechargeable energy storage system performance.
Compliance programmes often require evidence demonstrating that battery systems continue to operate safely following exposure to environmental, mechanical and electrical challenges throughout their service life.
Before lithium batteries can be transported commercially, they are typically required to demonstrate compliance with applicable transportation requirements.
UN 38.3 testing assesses battery suitability for transportation through a series of environmental and mechanical evaluations designed to simulate conditions encountered during shipping and logistics operations.
Testing may include:
Resonate Testing supports organisations seeking transportation approval for batteries used within electric vehicles and battery-powered systems.
Abuse testing forms a critical element of EV battery safety evaluation and helps manufacturers understand how batteries behave when subjected to extreme or fault conditions.
Our battery abuse testing capabilities can support investigations involving:
Battery abuse testing is often undertaken alongside compliance programmes to provide deeper insight into battery failure modes and safety performance.
Resonate Testing provides manufacturers with access to a multidisciplinary testing facility capable of supporting battery, environmental, vibration, shock and fire-related test programmes from a single location.
Whether you require UN 38.3 testing, support for a UNECE R100 programme or battery abuse testing for product development, Resonate Testing can help generate the evidence needed to demonstrate battery safety, reliability and compliance.
Electric vehicle batteries must continue to perform safely despite exposure to challenging environments throughout their operational life.
Resonate Testing combines battery expertise with extensive environmental and mechanical testing capability to assess battery performance under realistic service conditions.
