UL Solutions offers a comprehensive range of electric vehicle (EV) battery testing services, including abuse and fire exposure/thermal propagation and performance testing services at the cell, module and pack levels. We leverage these services to help EV original equipment manufacturers (OEMs), battery manufacturers and suppliers differentiate their batteries from competitors and boost end consumers’ confidence in the value of their products. We serve a wide range of industries, including automotive, aerospace, commercial and marine.
Our safety science, compliance expertise and innovative testing laboratories can help you efficiently and confidently navigate rapidly evolving requirements to bring energy technology products to market. By partnering with us, you can validate your EV batteries’ critical safety, reliability and performance characteristics and test against key regulations, standards and requirements — all with one testing services provider.
- Our EV battery testing services cover abuse testing, environmental testing, and performance evaluation:
- Thermal propagation testing via crush, heater, nail, overcharge, short circuit, or exposed flame
- Powered thermal cycle endurance
- High/low temperature operating endurance
- Immersion thermal shock testing (IPX7)
- Impact, drop, and altitude testing
- Vibration and shock testing
- Gas composition analysis
Thermal propagation and fire exposure testing services
Our team of experts uses modern equipment and technology to conduct thermal propagation and fire exposure testing and analysis. We deliver detailed test reports to help inform your decisions regarding:
- First responder strategy and tactics
- Vehicle installation and design validation
- Fire protection (integral or external) effectiveness
- Forensic analysis
We take an incremental approach to thermal propagation and fire exposure testing, from cell to pack level, to determine the minimum testing needed to prove product acceptance:
| Level | Activities |
| Cell | Develop cell thermal runaway initiation technique and characteristics, including gas composition. |
| Module | Determine propagation behavior within the module and thermal energy release outside of the module. |
| Pack | Open test configuration of module-to-module fire spread to determine the effectiveness of the anti-propagation barrier and insulating materials. Identify heat release rate and gas analysis to determine the potential for explosion. |
| Fire exposure | Controlled test configuration to determine the ability to prevent an explosion as a result of exposure to a simulated fuel or vehicle fire external to the electrical energy storage. |
We conduct battery testing in accordance with the following common standards as well as many others:
- UL 2580, the Standard for Batteries for Use In Electric Vehicles
- UN 38.3
- UNECE R100
- SAE J2464
- SAE J2929
- DO-311A
- IEC 62619
- IEC 62620
- IEC 62660-3
- FMVSS No. 305a
- GB 38031
