Large batteries for electric vehicles
Mitigate hazards for large format batteries with UL's Conformity Assessment Program.
With globalization, a variety of energy distribution systems, different voltages and safety concepts exist around the world. Self certification is prevalent with manufacturers having to determine a set of requirements that best meets their needs. Battery technologies, currently under development are likely to introduce the need for the consumers and EV stakeholders to be informed about personal protection, handling electrical grid voltage under hood and the need for fire suppression. Recharging of these batteries at home overnight, quick charging stations at business/parking lots and battery swapping create new uncertainties that the industry will be sorting out in the near future. To address the key industry challenges, UL is introducing new requirements for large batteries:
