Standards and Services
The standards are designed jointly with the key stakeholders of the electric vehicle landscape to help mitigate the potential risk of fire and electrical hazards and enhance the overall safety of batteries for electric vehicles. These standards evaluate the ability to safely withstand simulated abuse conditions based upon the manufacturer's specified charge and discharge parameters. The standard does not evaluate the interaction with other control systems within the EV or the performance or reliability of these devices.
Please also find more information related to the standards at our Code Authorities pages.
In addition to these safety requirements UL offers a broad range of performance verification services. Ultimately, UL's requirements for electric vehicle safety help move the industry toward performance and safety standardization.
UL's research team is collaborating closely with stakeholders involved with electric mobility, tailored to understanding failure modes and continuously improving standards, test methods, and thereby assuring safe products are entering global markets.
