As emissions mandates, government incentives, shifting economics and other factors drive the widespread transition to renewable energy and fuel the electric vehicle (EV) market’s continued growth, critical to success in this highly competitive market is the EV battery. In this transformative era, EV original equipment manufacturers (OEMs) and EV battery manufacturers’ success hinges on their ability to balance the speed of launching innovative products to market with achieving and validating performance criteria and demonstrating product compliance in dynamic supply chains.
Battery testing helps demonstrate performance and reliability and differentiates products in the marketplace. EV batteries must also meet regulatory, industry and manufacturer requirements and standards.
UL Solutions offers a comprehensive range of 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 OEMs, battery manufacturers and suppliers differentiate their batteries from competitors and boost end consumers’ confidence in the value of their products.
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 include:
- Fire exposure and thermal propagation testing
- Damp heat testing
- Splash water testing
- Immersion thermal shock testing (IPX7)
- Stone impact testing
- High-temperature operation endurance (HTOE) life cycle testing
- Crush and nail penetration testing
Abuse testing services for the EV battery cell, module and pack
Our EV battery abuse testing at the battery cell, module and pack levels covers a wide range of scenarios, including:
- Overcharging
- Overdischarging
- Thermal runaway
- Puncture
- Impact
We use industry-leading equipment and techniques to simulate these conditions and test the performance of your batteries under stress.
Our testing equipment includes:
- Shakers that can hold up to 3,000 kg
- Battery cyclers with capability of up to 1,500 V/500 kW
- Environmental chambers, including specialized chambers for the shaker tables — 2.3 m × 2.2 m × 3.1 m
- Fire test cells with thermal cameras, reinforced walls and explosion-rated blowout panels
- High-altitude simulation chambers
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. |
