Test programs for large batteries used in electric vehicles.

Competing in the global market requires manufacturers to determine early in the development cycle which energy distribution systems, voltages and safety concepts will best meet all of their customers’ needs. UL’s extensive safety science experience eases EV battery development processes for OEMs and battery manufacturers.

New Requirements for Large Batteries
Battery technologies currently under development are likely to introduce the need for consumers and EV stakeholders to be informed about personal protection, handling electrical grid voltage under the hood, and fire suppression. The industry continues to develop best practice guidance regarding the safest ways to recharge (or swap) these batteries at home or at public quick charging stations.

To address the key industry challenges, we have introduced new testing and certification programs for large batteries:

  • Batteries for Use In Electric Vehicles – UL 2580
  • Batteries for Use In Light Electric Vehicle (LEV) Applications – UL 2271
  • Road vehicles – Functional safety – ISO 26262

These tests evaluate the ability to safely withstand simulated abuse conditions based upon the manufacturer’s specified charge and discharge parameters. The standards were designed jointly with key stakeholders in the EV community to help mitigate the risk of fire and electrical hazards and to enhance the overall safety of batteries for EVs.
