UL Certifications for Energy Storage

UL 1973The energy storage industry has become highly regulated to ensure safe deployments in the field. The most widely adopted safety standard for energy storage systems is UL 9540, which requires electrochemical batteries inside of an ESS to be evaluated against UL 1973.

Nuvation Energy High-Voltage and Low-Voltage BMS modules have been UL 1973 Recognized and evaluated for functional safety, which dramatically reduces the UL 1973 certification effort. These modules have been evaluated using the UL 991 and UL 1998 standards for Functional Safety. UL’s RU Functional Safety Mark on our BMS modules is your assurance that our battery management systems arrive ready to support your UL 1973 and UL 9540 certification efforts.

With over one thousand configurable settings, Nuvation Energy’s BMS is one of the most flexible battery management systems in the world. So how does a configurable BMS get certified as functionally safe? When you request the UL 1973 Recognized variant, we will configure the BMS to manage your batteries to manufacturer specifications, lock down those functional safety settings at the factory, and provide a fingerprint of those settings that can be used to verify their correctness.

You will still be able to configure settings that do not impact functional safety. For example, if your PCS requires a certain voltage minimum to remain operational, you can program the BMS to communicate a warning or disconnect the batteries if the voltage drops below that PCS-driven threshold. Or if you’d like to ensure you can obtain a certain number of charge / discharge cycles over the life of the battery, you can dial in the min/max State of Charge (SOC) to increase the cycle count.

Many battery management systems exist to protect the battery and nothing more. Nuvation Energy’s BMS provides the best of both worlds with UL Recognition and configurable flexibility.
